The Bamboo Shark Fish Species

January 6, 2022 4 Mins Read

The bamboo shark is a little bottom dweller that moves slowly. Longtail carpet shark is their common moniker, and for good cause. They have extremely long tails that are much longer than the rest of their bodies. These sharks can be found on Pacific Ocean coral reefs. They’re prevalent throughout Indonesia’s coasts and in the surrounding waters, although the species’ range stretches from Japan to India.

In Madagascar and Taiwan, these sharks are also consumed by people. The white-spotted bamboo shark also known as Chiloscyllium plagiosum is a carpet shark that grows to be about a meter long in adulthood. Humans are unaffected by this small, primarily nocturnal species. The white-spotted bamboo shark is preserved on rare occasions.

Body Structure

Whitespotted bamboo sharks have a distinctive dorsal fin that influences where they choose to reside as well as how they move with convex posterior edges of the dorsal fins. Purple and pink spots with dark bands and a white body make up this color pattern. This family’s colour is distinct, making identification a breeze.

Bamboo Sharks frequently rest on the bottom of their habitat, held up by their bent and depressed pectoral fins, with their head and trunk propped up. Bamboo sharks’ teeth aren’t really different from one another. Every molar has a midline apex and moderate lingual base buds with 26–35 molars on the upper jaw and 21–32 teeth on the jaw bone.

Albinism in sharks is extremely unusual, and it has only happened a few times. It is estimated that one out of every 10,000 individuals of this species is born albino. At SeaWorld of Orlando, three albino white-spotted bamboo sharks have spawned.

Since 2007, the Downtown Aquarium in Denver, Colorado has seen annual hatchings of albino white-spotted bamboo sharks, and some are currently on display. These are some of the most frequent shark species kept in home aquariums due to their modest size and bottom-dwelling lifestyle. In captivity, they are easy to feed and breed.

Diets

These sharks hunt on small fish and invertebrates at night. Their teeth are tiny and can be used to grab or crush prey. When biting soft prey, the points of the teeth sink into the flesh, but when biting hard prey, the teeth pivot backward. The flattened front surface of the teeth forms a continuous plate for crushing crabs, protecting the tooth tip.

Adult sharks require more carbon than juvenile sharks, especially during the rainy season. Bamboo sharks have an edge over pelagic sharks since they are benthic predators. They have electroreceptors along their snout that help them discover prey buried in the sand and mud, making them particularly efficient users of this technology.

Their teeth are small as well, and they use them to grab or crush weaker prey. Their teeth can literally twist backward to consume harder shelled food! This protects the teeth’ tips and provides a continuous hard and flat surface on which to crunch crab or clamshells.

They have a maximum of 67 teeth. Bamboo sharks have spiracles, which are little apertures behind their eyes that allow them to take in oxygenated water. Their fins are tiny and unmuscled, and they mostly use them to support themselves up in the sand.

Breeding

Bamboo sharks are oviparous, which means they lay eggs. The eggs are about five inches in length and emerge after 14 or 15 weeks. The young are about 6 inches long when they hatch. A clutch of eggs from a female bamboo shark hatched without any visible mating in July 2002, according to Doug Sweet, curator of fishes at the Belle Isle Aquarium in Detroit. This appears to be the first time parthenogenesis has been observed in this species.

Atlantic Salmon Fish – 7 Awesome Species | Characteristics, Feeding, Breeding

December 30, 2021 4 Mins Read

The Atlantic Salmon Fish is a ray-finned fish belonging to the Salmonidae family, they can survive in both fresh and saltwater. It is the third-largest Salmonidae species, after Siberian Taimen and Pacific Chinook Salmon, and can reach a length of one meter. Atlantic salmon can be found in rivers that drain into the ocean and in the northern Atlantic Ocean.

The majority of these fish species’ populations are anadromous, meaning they hatch in streams and rivers but migrate out to sea as they grow to mature, after which the adult fish return upstream to reproduce. The life cycle of Atlantic salmon begins with spawning and juvenile rearing in rivers. To feed, grow, and mature, they go to saltwater.

The color and look of mature fish change as they return to rivers to reproduce. Some populations of this fish are “landlocked,” meaning they only travel to large lakes and spend their whole lives in freshwater. These populations can be found all over the species’ range.

Individuals of this type can grow to enormous proportions, although they are uncommon. Bay salmon, black salmon, caplin-scull salmon, fiddler, Sebago salmon, silver salmon, outside salmon, and winnish are some of the other names for Atlantic salmon. They are known as parr, smolt, grilse, grilt, kelt, slink, and spring salmon at various stages of their maturity and life cycle.

Body Structure of Atlantic Salmon Fish

The pigmentation of young Atlantic salmon differs from that of adults. They have blue and red markings when they are in freshwater. They have a silver-blue luster as they mature. The black spots mostly above the lateral line, but the caudal fin is normally unspotted, are the clearest way to recognize them as an adult. Males turn a faint green or red color when they reproduce. The salmon’s body is fusiform, and its teeth are well developed. Except for the adipose fin, all fins are dark-skinned.

The fish average 71 to 76 cm in length and 4 to 6 kg in weight after two years at sea. Specimens that spend four or more winters feeding at sea, on the other hand, can grow to be much larger. An Atlantic salmon caught in the estuary of the River Hope in Scotland in 1960 measured 49.44 kg, the biggest recorded in all known literature. Another, caught in Norway in 1925, measured about 161 cm in length, making it the world’s longest Atlantic salmon.

Habitat

The Housatonic River and its tributary, the Naugatuck River, housed the United States’ southernmost Atlantic salmon spawning runs. However, Henry Hudson claimed in 1609 that Atlantic salmon previously ran up the Hudson River. Furthermore, fish scale evidence from 10,000 years ago places Atlantic salmon in a pond on the shore of New Jersey. Rivers in Europe and the northeastern coast of North America are natural breeding places for Atlantic salmon.

Atlantic salmon can still be found in Europe, as far south as Spain, and as far north as Russia. Some of the species’ southern populations in northern Spain are shrinking due to sport fishing. Changes in the freshwater environment and climate have a big impact on species distribution. Because Atlantic salmon is a cold-water fish, it is extremely sensitive to variations in water temperature.

Diets

Within a few days, juvenile salmon develop a feeding reflex. They start hunting after the yolk sac is absorbed by the body. Juveniles eat small invertebrates at first, but as they grow older, they may devour small fish. They hunt both in the substrate and in the current during this period. Salmon eggs have been known to be consumed by some. Caddisflies, blackflies, mayflies, and stoneflies are the most regularly eaten insects. Salmon prefer capelin as a meal when they are adults.

Arripis Trutta: Australian Salmon Fish Breed – 3 Beautiful Species info, Pictures and facts

December 30, 2021 4 Mins Read

Arripis Trutta: Australian Salmon Fish Breed is not related to salmons or trouts of the family Salmonidae, despite the fact that it is referred to as a salmon in Australia and its species trout. Eastern Australian salmon, bay trout, black back, blackback salmon, buck, buck salmon, cocky salmon, colonial salmon, newfish, and salmon trout are some of the other frequent names for this species.

Arripis Trutta: Australian Salmon Fish Breed, also known as kahawai in New Zealand and Australian salmon in Australia, is one of four marine fish species found in colder waters around Australia’s southeastern and southwestern shores, as well as the New Zealand shoreline. Salmon form massive schools, weighing up to a hundred tonnes and containing thousands of individuals.

Body Structure of Australian Salmon

Arripis trutta is a tall and skinny fish with a streamlined body. In smaller individuals, a bony ridge edge of bone beneath and in front of each eye displays visible serrations. The scales of larger fish are smoother. The caudal fin’s lobes are about the same size as the head. The dorsal side of these fish is dark bluish-green, while the ventral side is silvery white.

The upper flanks of juveniles have golden bars, which break up into large spots as the fish grows older. The caudal and spiny parts of the dorsal fin have a blackish margin, and the pectoral fin is bright yellow. In the dorsal fin, there are 9 spines and 15-17 soft rays, and 3 spines and 9-10 soft rays in the ventral fin.

The highest total length recorded is 89 centimeters, though most are around 47 cm long, and the maximum weight recorded is 9.4 kilos. The gill raker count is the most persistent difference between this species.

Habitat

Arripis Trutta: Australian Salmon Fish Breed are long-distance migratory fish that can travel thousands of kilometers. The adults form vast schools along oceanic beaches and exposed coastal areas, congregating in very large schools off oceanic beaches and exposed coasts. They are found in colder southern seas in Western Australia, but they are also frequent in regions north of Perth during the winter months.

Adult Arripis trutta prefer clear, shallow waters along surf beaches, rocky reefs, and coastal estuaries, but some schools can also be found in deeper offshore areas.

Salmon are temperature-sensitive, and their seasonal travel is linked to the strength of the Leeuwin Current and Capes Current, as well as subsequent water temperatures. Warmer coastal waters cause fish to congregate in certain seasons in deeper cooler offshore water.

Large schools of salmon were seen in south-western waters as far north as Exmouth in 2015 and 2016, which is further north than ever before reported. Arripis trutta can be found off the coast of Australia and New Zealand in the southern Pacific Ocean.

They can be found from Moreton Bay in Queensland to western Victoria and northern Tasmania, with sporadic sightings on South Australia’s Kangaroo Island. In the Tasman Sea, they can also be seen around Lord Howe Island and Norfolk Island. They are found all along the coast of New Zealand but are more numerous north of Kaikoura on the South Island.

Diets

It’s a carnivorous species that eat pelagic fish that are not big and pelagic crustaceans like shrimp. During their juvenile phase, they feed a range of crustaceans and polychaetes; but, as adults, they prefer small schooling fish, baitfish such as pilchards, sprats, and anchovies.

Larger apex predators like seals, dolphins, and sharks hunt on Arripis trutta. The feeding salmon schools drive the schools of fish they prey on to the surface, allowing seabirds to eat on them.

When they are roughly four years old and have grown to a length of 39 cm, they spawn for the first time. They have a lifespan of up to 26 years.

Bala Shark Fish Specie

December 23, 2021 4 Mins Read

Bala Shark Fish Specie: Balantiocheilos melanopterus, often known as the tricolor shark, tricolor sharkminnow, silver shark, or shark minnow, is one of two species in the genus Balantiocheilos. This species is not a genuine shark, but its torpedo-shaped body and huge fins have earned it the name. It was first described by Bleeker in 1851 under the name Barbus melanopterus.

The Malay Peninsula, Sumatra, and Borneo are home to the Bala shark. Confusion with the recently described and potentially extinct B. ambusticauda led to previous records further north in the Mekong and Chao Phraya Rivers. The species was also considered to live in Thailand’s Mekong and Chao Phraya rivers. However, in 2007, Ng and Kottelat confirmed that this information was incorrect.

Bala Shark Fish Specie Body Structure

The dorsal, caudal, anal, and pelvic fins have black borders, and the dorsal, caudal, anal, and pelvic fins are silver. To locate and catch their prey, they have large eyes. The Bala shark can grow up to 35 centimeters in length, with females being smaller. The scales of the Bala Shark are well-defined and have a silver metallic luster. The hue darkens as it gets closer to the top and fades as it gets closer to the bottom.

Many river basins in their natural range have become rare or extinct. Fishermen in Danau Sentarum (Borneo) stated in 1993 and 1995 that population levels had dropped substantially after 1975 for no apparent reason. Overfishing for the aquarium fish trade or forest fires in 1975, which resulted in contamination, was named by fishermen as a possible cause. The species is believed to be extinct in the Batang Hari basin (Sumatra), and all B. melanopterus individuals exported to the aquarium trade from Indonesia and Thailand are captivity bred.

Habitat

Bala sharks can be found in big and medium-sized rivers and lakes at midwater depths. They are resilient fish that can withstand temperature variations, pH changes, and other variables that would harm other fish. The pH of the water should be between 6.0 and 8.0. Soft to medium water hardness is ideal for this species. The water temperature should be regulated between 22 and 28 degrees Celsius (72 and 82 degrees Fahrenheit). Bala sharks prefer to be kept in pairs or groups of two or more. Because it is a proficient jumper, it requires a covered aquarium, although it may damage itself on the tank’s lid.

Diets

They eat phytoplankton and small crustaceans, rotifers, and insects and their larvae, but predominantly small crustaceans, rotifers, and insects and their larvae.

These fish would form shoaling groups while they hunted for food, escaped predators, and looked for mates in the wild. Bala Sharks must be with their species to avoid developing harmful habits that could lead to their premature death.

Small fish can be eaten by Bala Sharks if they are small enough to fit in their mouth. Snails, which are a component of their natural diet, are also a favorite food for these opportunistic feeders. Arowanas, big cichlids, and pufferfish are some of the predatory animals to watch.

Behavior

Once they’ve become used to their new surroundings, Bala Sharks will become more active. They’ll be grouped together in close proximity. They would sometimes imitate each other’s movements, and jumping is a good defense tactic. It allows fish to flee from their predators for a short time.

Reproduction

Bala Sharks don’t have the best parenting skills. Once the eggs have been placed and fertilized, females pay little attention to them. Males do not offer protection to their offspring. Males and females would devour their eggs and newly hatched fry, in reality.

Caring

You’ll need to feed your fish the right diet at the right time, and you’ll need to keep an eye on the water conditions. They can survive for up to ten years on average.

The Atlantic Cod Fish Species

December 23, 2021 4 Mins Read

The Atlantic Cod Fish Species (Gadus morhua) is a benthopelagic fish belonging to the Gadidae family, which includes 22 different species. Cod can be found north of Cape Hatteras, North Carolina, and around both the coasts of Greenland and the Labrador Sea in the western Atlantic Ocean; in the eastern Atlantic, it can be found from the Bay of Biscay north to the Arctic Ocean, including the Baltic Sea, the North Sea, the Sea of the Hebrides, areas around Iceland, and the Barents Sea.

Along with Pacific cod and Greenland cod, the Atlantic cod is one of three species in the genus Gadus. Cod refers to a range of fish species, not all of which are classed as Gadus, though some do belong to the Atlantic cod family, Gadidae.

Cod drew Europeans to North America for short fishing trips and later persuaded them to stay as fishermen benefitted from the flaky white flesh, high protein content, and low-fat level of this fish. As Europeans explored North America in search of a route to Asia, they discovered an abundance of enormous cod and began fishing along the coast of what is now New England, using makeshift fishing encampments.

One of the most extensively fished species is the Atlantic Cod Fish Species. North European fishermen have been catching Atlantic cod for a thousand years, following it across the North Atlantic Ocean to North America. It aided the US and Canadian fishing industries until 1992 when cod fishing was prohibited. Several cod stocks crashed in the 1990s (losing more than 95 percent of their maximum historical biomass) and have yet to fully recover, even after fishing was stopped. In many locations, the lack of an apex predator has resulted in a trophic cascade. Many other cod stocks are still in jeopardy.

The Atlantic Cod Fish Species Body Structure

The biggest cod ever recorded was 1.5 meters long and weighed 47 kilograms, however, most cod is between 60 and 120 centimeters long and weigh up to 40 kilograms. The size and weight of men and females are similar. Its habitat stretches from the coast to the continental shelf, down to 300 meters (1,000 feet). One of the most extensively fished species is the Atlantic cod.

Brown or green in color, with dots on the dorsal side that fade to silver ventrally. There is a visible stripe along its lateral line used to detect vibrations. The lateral line is a light line that runs down the side of their body. Their chin has a conspicuous barbel, or whisker-like projection, giving them a catfish-like appearance. Individuals have three dorsal fins and two anal fins, which are all pronounced.

Behavior

Atlantic cod are shoaling fish that congregate in huge, size-structured groups. Larger fish operate as scouts and guide the shoal in the right direction, especially during post-spawning feeding migrations inshore. During migration, cod actively feed, and when food is encountered, shoal structure changes. Shoals are assumed to be rather leaderless, with all fish having similar status and resources and benefits distributed equally.

In the Baltic, Atlantic cod are apex predators, and adults are largely unaffected by predation. Adult cod, on the other hand, may hunt on juvenile fish, who are known to perform cannibalism.

During the day, swimming speed was faster than at night. This is mirrored in the fact that cod search for food more vigorously during the day. Cod’s activity pattern is expected to change depending on the length of daylight, therefore activity fluctuates throughout the year.

Diets

Fish such as herring, capelin, and sand eels, as well as mollusks, crabs, and sea worms, make up the diet of Atlantic Cod Fish Species. Fish is the primary food source for huge Atlantic cod. Decapods are the predominant food source in some areas, with fish serving as a supplement to the diets.

Reproduction

Atlantic Cod Fish Species reproduce once a year during a one- to two-month spawning season. Males and females congregate in spawning schools, which produce an average of 8.3 egg batches per spawning season. Spawning takes place in February or April, with a female having up to 9 million eggs. In the water, the eggs and newly hatched young float freely. Males fertilize the released eggs after females release gametes in a ventral mount.

Size-based reproductive hierarchies exist among cod males. Larger cod males are more successful in mating and produce the greatest number of progeny in a community.

The Atlantic Bonito Fish Breed

December 16, 2021 3 Mins Read

The Atlantic bonito fish breed is part of the same mackerel family (Scombridae) as tuna. The bonito is a strong swimmer and travels in fairly large schools. It is common for bonito to travel in shallow waters that have lots of baitfish, which they like to eat.

Bonitos are a ray-finned predatory fish of the Scombridae family, which also includes the mackerel, tuna, and Spanish mackerel tribes, as well as butterfly kingfish.

The Atlantic Bonito is a huge tuna and mackerel that belongs to the Scombridi family of fish. The Sarda Sarda range stretches from the eastern Atlantic’s Mediterranean Sea and the Black Sea to Norway, South Africa, and Nova Scotia, all the way to the western Atlantic’s northern Gulf of Mexico. It has been discovered in Colombia and Venezuela, despite the fact that it is not usually seen in the Caribbean Sea.

Body Structure of Atlantic Bonito Fish Breed

The Atlantic bonito differs from its relative by having dark oblique stripes on the back and a maxillary that is only about half the length of the head, whereas the striped bonito has nearly horizontal striping on its topside and a maxillary that is more than half the length of the head. Atlantic bonito can reach 75 centimeters (30 in) in length and weigh 5–6 kilograms (11–13 lb). In the Azores, a fish weighing 18 pounds 4 ounces (8.3 kg) set the world record.

The dorsal fins of Atlantic bonito are relatively close together or separated by a short interspace. It has a totally scaled body, with the scales on the pectoral fin and lateral line being the largest. Bonitos (fish belonging to the genus Sarda) are distinguished from tuna by their compressed bodies, lack of teeth on the roof of the mouth, and color differences.

The striped bonito, Sarda orientalis, and Atlantic bonito share Atlantic waters. The striped bonito have been caught as far north as Cape Cod on the Atlantic coast. Its behaviors are similar to those of the more widespread Atlantic bonito, but it is slightly smaller.

Habitat and Diets of Atlantic Bonito Fish Breed

It usually travels in big groups and can be found off the coast of New York City, where it is known as “skipjack” due to its propensity of jumping out of the water. The spawning season is in June, and specimens measuring 12–15 centimeters (4.7–5.9 in) long are collected off the coast of Long Island in September.

Skipjack tuna is a small, wide-bodied fish that has longitudinal stripes on its back. It is the only tuna with such stripes on its back; all others have them on their abdomen. Skipjack tuna’s upper sides and back are steel blue in color.

The Atlantic bonito has been a tireless hunter. They consume a wide variety of fish, including herring, menhaden, hake, mackerel, anchovies, shrimp, and squid. They have been reported to survive for at least nine years, but they aren’t particularly large fish.

Uses of Atlantic Bonito Fish Breed

Bonito is a popular Mediterranean culinary fish with meat that is comparable to tuna and mackerel and a size that is halfway between the two. Tuna fishermen frequently catch bonito while trawling for larger animals. Most fishermen consider it to be inferior to tuna as a food fish, probably due to its higher oiliness, however, it is occasionally used as bait.

The Asian Carp Fish Breed

December 16, 2021 4 Mins Read

The Asian Carp Fish Breed refers to a group of heavy-bodied cyprinid fishes that are found in the United States. Cyprinids from the Indian subcontinent, such as catla (Catla catla) and mrigal (Cirrhinus cirrhosus), are not classified and are collectively referred to as “Indian carp.” In the United States, Asian carp are classified as an invasive species.

To help clean their commercial ponds, fish growers in predominantly southern areas began importing Asian carp from China in the 1970s. Bighead and silver carp populations have exploded where they’ve established themselves in the Mississippi River basin.

Humans are also responsible for the spread of invasive carp. Young carp have been introduced to other bodies of water thanks to the release of live bait carrying these fish. Invasive carp may be able to get through Mississippi River locks carried by barges and recreational watercraft.

Carp are a type of fish that can be found in Europe and Asia. The common carp (Cyprinus carpio) has been found in the United States for more than a century. Bighead carp, black carp, grass carp, and silver carp are together known as “Asian carp, the newest carp invaders, are inflicting their own brand of havoc in the Mississippi River and its surrounding rivers and lakes.

These four fish species were imported to the United States in the 1970s to limit the growth of algae, weed, and parasite growth in aquaculture, weeds in canal systems, and as a sewage treatment method.

Carp are also known to degrade water quality, causing sensitive creatures such as native freshwater mussels to perish. Carp from Asia have been known to take over entire streams, essentially displacing native species. Because Asian carp out-compete other fish for food and space in the lakes and rivers they infest, they cause considerable damage to native fish populations.

Distribution of Asian Carp

Mississippi River basins are known to contain well-established Bighead, silver, and grass carp, where they can reach extremely high populations, particularly for bighead and silver carp. From Louisiana to South Dakota, Minnesota, and Ohio, bighead, silver, and grass carp have been caught in that watershed. Grass carp have been found in at least one additional watershed in Texas, and they could be found further.

Grass carp have been caught in all of the Great Lakes except Lake Superior, but no indication of a reproducing population has been found thus far. There have yet to be any silver or black carp discovered in any of the Great Lakes. The Great Lakes are teeming with common carp.

Behavior of The Asian Carp Fish Breed

Boats often frighten silver carp, causing them to leap up to 2.5–3.0 meters (8–10 feet) into the air, and encounters with the fish have resulted in countless boaters being badly hurt. “Reported injuries include cuts from fins, black eyes, broken bones, back injuries, and concussions,” according to the Environmental Protection Agency. This behavior has been attributed to the closely related bighead carp; however, these fish do not generally jump when startled.

Diets

Carp are voracious feeders and can grow to be extremely enormous. Exceptional people can weigh up to 110 pounds, but the majority of them are much lighter. When introduced to new settings, several Asian carp species can cause harm. Native mussels and snails, some of which are already endangered, are eaten by black carp. By modifying the populations of plants, insects, and fish, grass carp can change the food webs of a new environment. Silver carp eat the plankton that larval fish and mussels need to survive.

Breeding The Asian Carp Fish Breed

Adult carp stay in slow-moving water, but when it comes to laying eggs, they prefer high, fast-moving water during spawning. They lay hundreds of thousands of eggs at a time, allowing populations to quickly expand and spread. As a result, they can quickly outcompete native species, putting ecosystems at risk.

Arowanas fish species

December 9, 2021 4 Mins Read

Arowanas, also known as bony tongues, are freshwater fish that belong to the family Osteoglossidae. They can be found in freshwater streams and rivers of Australia, Africa, Asia, and South America. The Arowana is the only species of fish that is native to both Asia and Australia. There are 10 common types of Arowana kept as pets; four from Asia, three from South America, two from Australia, and one from Africa.

Arowanas are a type of fish that are native to the Amazon Basin, tropical and subtropical regions. There are a number of different species of this fish, all with their own unique differences. and have been popular among aquarium enthusiasts for over three decades. Arowana species, like other types of fish, vary in appearance. Some species come in brilliant arrays of color, from bright red to dazzling silver.

Different species of Arowanas can be found in different regions of the world. In South America, there are two species, silver, and black Arowana. A number of species are located in Asia; including the endangered Asian Arowana. Two species live in Australia, while a single species lives in India.

Bonytongues derive their name from the fact that they have a toothed bone on the floor of their mouth. Their teeth bite against teeth located on the roof of their mouth, which is called the roof of the bony tongue’s mouth. The Arowana is capable of breathing air and can absorb oxygen through its swim bladder, which has capillaries.

Arowanas are known for being difficult pets to maintain. They are expensive, require lots of space, need to be fed a special diet, and have a tendency to be aggressive.

Osteoglossids are carnivorous surface feeders. They have excellent jumping abilities, making them great at catching insects and birds. Osteoglossum species have been seen leaping more than 6 ft from the water surface to pick off insects or birds overhanging branches.

Body Structure

The head of an Arowana is bony and the elongated body is covered by large, heavy scales, which have a mosaic pattern of canals. The dorsal and anal fins are long based, but the pectoral and ventral fins are small.

Arowanas are large fish with elongated bodies. Their mouths face upwards, so they can catch food from the surface of the water. These fish are usually silver or blue in color and have a long, eel-like body. They come in a variety of colors, including red.

Arowana is also characterized by two, darkly colored, barbells that extend from its bottom lips. These barbells can be delicate and easily damaged. The species typically grow to around 2 to 3 ft.

Habitat

Arowana species usually live in freshwater environments; they are common in rivers, lakes, ponds, river basins. They can survive in environments with less oxygen than many other fish species, which helps them avoid competition. In low-oxygen habitats, preys tend to be more sluggish and easier to catch.

Diets

These Arowanas fish have a variety of prey. They eat basically anything that fits in their large mouths and they mainly feed at or near the surface. Their main food consists of crustaceans, insects, small fish, and basically anything that falls into the water.

Biology

Arowanas display parental care, which is unusual among fish. They build nests and protect their young after they hatch. They are mouthbrooders, holding sometimes hundreds of eggs in their mouths. The young may make several tentative trips outside the parent’s mouth to investigate the surroundings before leaving. Unlike most fishes that start reproducing at around six months of age, the Arowana usually takes three to four years to reach sexual maturity.

Armored catfish species

December 9, 2021 3 Mins Read

The Loricariidae, or the armored catfish, is one of the largest families of catfish. There are over 650 species of this fish currently known. More are being discovered yearly, with an overabundance in some regions. In North America, two types of armored catfish have been recognized: the armadillo del Rio, Hypostomus plecostomus, and sailfin catfishes in genus Pterygoplichthys. Their native range is the Amazon River Basin.

Invasive armored catfish have been around in Florida since the 1950s, and they are also seen in Texas. They were first seen in Mexico 15 years ago within the Reservoir El Infiernillo in Michoacán in central Mexico.

The armored catfish (Loricaria armata) is native to Africa and Costa Rica. It lives in warm freshwater habitats such as the tropical regions of both Africa and Costa Rica or large lakes in Texas and Florida. This fish has been relocated by owners and released into the wild after hurricanes, growing to enormous numbers in various parts of the globe.

The armored catfish is a freshwater fish that can tolerate average salinity, and it lives in the Southeastern region of the United States. The bony spines of this fish aren’t poisonous; they are used as protection to keep off predators. Scared or threatened, the armored catfish extends its fins to keep away from being swallowed. it may well survive in low-oxygen waters, gulping air and surviving out of water for greater than 30 hours due to vascularized abdomen which enable it to breathe air.

Due to the fact that they eat fish eggs, armored catfish can wipe out an entire species or at least cause numbers of other fish to drastically decline. Then, they lay their own eggs by the thousands. The male fish protects the eggs so that other species of fish cannot hurt the unborn fish, guaranteeing their survival. These invasive creatures have become a problem in many areas.

Body Structure

The armored catfish got its name from the way it looks. The armored plates that cover its body make it look like a suit of armor. Armored catfish grow to be about 12-20 inches long and weigh 1.5-2.5 kilos (3.3-5 pounds). They are nocturnal, with eyes adapted to low light conditions. The armored catfish lives in freshwater, however, can tolerate average salinity.

The armored catfish is covered in bony plates, has a triangular shape with a smooth bottom, and is spotted in a leopard pattern. Its mouth lacks teeth but scrapes algae from submerged tree trunks, rocks, and river bottoms.

Diets

The armored catfish have a limited diet due to the fact that it does not have any teeth. They survive by sucking the algae off of underwater plants or the bottom of a riverbed, as well as fish eggs.

Biology

In the wild, armored catfish will create lengthy burrows along shorelines and females will deposit eggs. These burrows can collapse under the weight of a human, becoming nuisances that can cause damage and increase the chance of abrasion on the canal and water bank.

Males stick around to guard the nest and the female may lay more than 300 eggs in their nests. Loricariids are cavity builders and may lay eggs in four to 20 days, depending on the species. Males guard the nests and may also stand up to a variety of ecological situations, they are extremely territorial.

The Archerfish Species

December 2, 2021 4 Mins Read

The Archerfish Species is a monotypic family. The archerfish, or spinner fish, is a saltwater fish that lives in the Pacific and Indian oceans. The family is small and consists of ten species in a single genus, Toxotes. Most species live in freshwater rivers, streams, pools, and estuaries. Two or three of the species are euryhaline: they inhabit both fresh and brackish water.

One of the species, T. jaculatrix, is found in freshwater rivers and streams as well as brackish mangrove swamps. The Archerfish is a tropical and subtropical fish that can be found in Southeast Asia, Northern Australia, India, Sri Lanka, Bangladesh, and Melanesia.

The archerfish is known for its unique hunting method. Its diet consists of land bugs and other small animals, which it shoots down with a jet of water. They are able to shoot prey down with water droplets from their specialized mouths. The archerfish hunts for food with the help of a glandular secretion from the roof of its mouth, which shoots an insect attracting prey.

Archerfish are notoriously unique in their shooting. Almost every time, an adult fish hits the target on the first shot. While it is widely believed that all archerfish species do this. They can bring down insects and other prey up to 3m above water level. This is partially due to their good eyesight, but also to their ability to compensate for refraction.

When an archerfish chooses its prey, the fish rotates its eye so that the image of the prey falls on a particular portion of the eye. The fish then squirts a jet of water at its victim by forming a small groove in the roof of its mouth and tongue into a narrow channel. The archerfish does this by contracting its gill covers and forcing water through the channel.

The position of the fish that shoots up to seven times in succession is directly beneath the prey, and they learn this is their best shooting spot. When shooting up to three meters, they are accurate only around one to one and a half meters. The blast of water may not bring down insects but the weight of the water on its wings brings it down.

Body Description of The Archerfish Species

The archerfish is a small fish, and its body can grow up to 15 cm long. It has silver stripes and two black spots on top of its head. An archerfish is a small tropical fish that lives in large rivers, lagoons, and lakes with abundant growth of water hyacinths. It is characterized by its largemouth, the depths of which are about one-third the length of its head.

The trunk has two pairs of fully formed fins: pectoral fins and pelvic fins. The fish has a slender body with a pointed face. The dorsal and anal fins are far back on the body, and the tail has a rounded edge. It is silver-gray or greenish-brown with yellow spots on its sides.

The Banded Archerfish have four to six black vertical bars on its body. The first bar is across the eye, and the last is before the tail end. These black bars are also seen in their dorsal fin as well as their anal fin. Since they have these bars it was given its name of Banded Archerfish.

Diets

Since they are omnivores, they can be fed live insects, mealworms, and freeze-dried plankton. Dry seaweed can also be given to them as they grow. Smaller fish can also be given to them as they grow since they hunt other aquatic creatures in the wild too. Most insects are eaten with relish. They have an average life of 8-10 years to live.
