Vimba Vimba Fish


Binomial Name: Vimba Vimba
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Cypriniformes
Family: Cyprinidae
Subfamily: Leuciscinae
Genus: Vimba
Species: V. vimba

Other Names: vimba bream, vimba,zanthe, or zarte

Habitat:
Vimba vimba is distributed in fresh waters and in brackish estuaries of rivers draining to the Caspian Sea, Black Sea and Baltic Sea, and in the North Sea basin in the Elbe and Ems drainages. There are records from Armenia, Austria, Azerbaijan, Belarus, Bulgaria, Czech Republic, Estonia, Finland, France, Georgia, Germany, Hungary, Iran, Latvia, Lithuania, Moldova, the Netherlands, Poland, Romania, Russia, Serbia and Montenegro, Slovakia, Sweden, Switzerland, Turkey, and Ukraine.

The vimba bream is a semi-anadromous fish, which migrates from brackish water to rivers for spawning. Permanently fresh-water populations exist as well. In the Baltic Sea the species is distributed up to 62°-63° N in Sweden and Finland.

Description:

The vimba bream was at one time classified as a bream as it also has a long anal fin, but has now been placed in a different genus. Its body is not as deep as that of the bream. It also resembles the asp but its mouth is small and behind the snout whereas the asp has a large mouth with the lower jaw protruding. This species grows to about 25 to 45 centimetres (9.8 to 17.7 in) with a weight of up to 2 kilograms (4.4 lb). The scales are small and there are about sixty of them along the lateral line. This fish is a deep bluish-green on the dorsal surface and silvery along the flanks. The eyes are yellow and the pectoral and pelvic fins have reddish-yellow bases. The colouring becomes more vivid in the breeding season and males may have the operculum, base of the fins and the belly turn orange.

Vimba breams move in small shoals along the sea coast, feeding on invertebrates which they pick from the seabed, and the eggs of other fish. They leave the sea in May or June, swimming upriver to spawn in fast-moving tributaries with stony or gravelly bases and little vegetation. The males prepares several areas of riverbed on which the females deposit batches of eggs. In Lithuania, there is a festival each year along the shore of the Neman River to celebrate the arrival of the fish.

Useful properties and composition vimba vim:
Meat vimba contains much protein, which in its nutritional value can be compared with meat protein, and even more – vimba protein does not contain harmful saturated fat consists of essential amino acids, which are essential for full functioning of the human organism. These amino acids include lysine, methionine, taurine, and tryptophan. Taurine – the most useful amino acid that the air is needed for people suffering from atherosclerosis, edema, hypertension and other problems with the cardiovascular system. Therefore Sirt is extremely useful for people with the above problems. In addition, the protein found in fish, is easily digestible and easily digestible. Vimba smoked

Like the other inhabitants of the water depth, vimba contains some vitamins, macro- and microelements, which are dominated by fluorine. As is known, it is necessary for the body to tissue strength bone and tooth enamel, as well as the health of brain cells and the blood. Fluoride prevents the development of dental caries, rickets and osteoporosis. Many contained in vimba chromium, which promotes the absorption of carbohydrates, improves myocardial metabolism and regulates blood glucose and molybdenum helps to prevent anemia.

From vitamins vimba present only vitamin PP, or niacin. Vitamin PP is actively involved in carbohydrate and protein metabolism, and normalizes the activity of the nervous system, contributes to the work of the brain, reducing the level of bad cholesterol in the blood.

Known Hazards: Due to the relatively high calorie vimba it is not recommended to use for people who are overweight. Also abuse of the meat vimba liver and pancreas is not advisible.

Vhetki Fish. (Barramundi)

Binomial Name: Lates calcarifer
Kingdom: Animalia

Phylum: Chordata
Class: Actinopterygii
Order: Perciformes
Family: Latidae
Genus: Lates
Species: L. calcarifer

Other Names:Asian sea bass
Bengali Name : Vhetki Fish

Habitat:
The barramundi (Lates calcarifer) or Asian sea bass, is a species of catadromous fish in family Latidae of order Perciformes. The species is widely distributed in the Indo-West Pacific region from Southeast Asia to Papua New Guinea and Northern Australia. Known in Thai language as pla kapong, it is very popular in Thai cuisine.

Description:
This species has an elongated body form with a large, slightly oblique mouth and an upper jaw extending behind the eye. The lower edge of the preoperculum is serrated with a strong spine at its angle; the operculum has a small spine and a serrated flap above the origin of the lateral line. Its scales are ctenoid. In cross section, the fish is compressed and the dorsal head profile clearly concave. The single dorsal and ventral fins have spines and soft rays; the paired pectoral and pelvic fins have soft rays only; and the caudal fin has soft rays and is truncate and rounded. Barramundi are salt and freshwater sportfish, targeted by many. They have large, silver scales, which may become darker or lighter, depending on their environments. Their bodies can reach up to 1.8 m (5.9 ft) long, though evidence of them being caught at this size is scarce. The maximum weight is about 60 kg (130 lb). The average length is about 0.6–1.2 m (2.0–3.9 ft). Its genome size is about 700 Mb, which was sequenced and published in Animal Genetics (2015, in press) by James Cook University.

Barramundi are demersal, inhabiting coastal waters, estuaries, lagoons, and rivers; they are found in clear to turbid water, usually within a temperature range of 26?30 °C. This species does not undertake extensive migrations within or between river systems, which has presumably influenced establishment of genetically distinct stocks in Northern Australia.

Life cycle:
The barramundi feeds on crustaceans, molluscs, and smaller fish (including its own species); juveniles feed on zooplankton. The barramundi is euryhaline, but stenothermal. It inhabits rivers and descends to estuaries and tidal flats to spawn. In areas remote from fresh water, purely marine populations may become established.

At the start of the monsoon, males migrate downriver to meet females, which lay very large numbers of eggs (several millions each). The adults do not guard the eggs or the fry, which require brackish water to develop.

The species is sequentially hermaphroditic, with most individuals maturing as males and becoming female after at least one spawning season; most of the larger specimens are therefore female. Fish held in captivity sometimes demonstrate features atypical of fish in the wild: they change sex at a smaller size, exhibit a higher proportion of protandry and some males do not undergo sexual inversion:

Uses:
As Food: Barramundi have a mild flavour and a white, flaky flesh, with varying amount of body fat.

In Australia, such is the demand for the fish that a substantial amount of barramundi consumed there is actually imported. This has placed economic pressure on Australian producers, both fishers and farmers, whose costs are greater due to remoteness of many of the farming and fishing sites, as well as stringent environmental and food safety standards placed on them by government. While country of origin labelling has given consumers greater certainty over the origins of their barramundi at the retail level, no requirement exists for the food service and restaurant trades to label the origins of their barramundi.

In the US, barramundi is growing in popularity. Monterey Bay Aquarium has deemed US and Vietnam-raised barramundi as “Best Choice” under the Seafood Watch sustainability program.

Barramundi are a favorite food of the region’s apex predator, saltwater crocodiles, which have been known to take them from unwary fishermen.

Nile perch—a similar fish found in the Afrotropic ecozone, or sub-Saharan Africa—is often mislabeled as barramundi.

Bengali cuisine:
Locally caught bhetki (barramundi) is a popular fish among Bengali people, mainly dished in festivities like marriages and other important social events, cooked as Bhetki macher paturi, bhetki macher kalia or coated with suji (semolina) and pan fried. It is very popular among people who are usually sceptical to eat fish because of their tiny pin bones. Bhetki fillets have no pin bones in them. In Bengali cuisine therefore the fry of “Bhetki” fillets is popular, commonly known as “Fish Fry” which is considered to be of good quality if it is made of this fish.

Neutricinal value:

Low in Fat:
A 6-ounce fillet of fresh barramundi contains 140 calories, and 13 percent of this amount — approximately 18 calories, or 2 grams — comes from fat. For a woman on a 2,000-calorie diet, a serving of barramundi would supply only 2 to 3.5 percent of her recommended daily limit of fat. Barramundi contains no saturated fat, although it does have 70 milligrams of cholesterol, which is 23 percent of the total a healthy adult should have each day. Columbia Health assures that, despite the cholesterol content, the health benefits of fish like barramundi still make it a good choice in a balanced diet.

Rich in Omega-3 Fatty Acids:
A serving of some commercially farmed barramundi contains about 1 gram of omega-3 fatty acids, nearly as much as the 1.5 grams of omega-3 fatty acids found in every serving of fatty fish like salmon, mackerel or herring. There isn’t a recommended daily allowance of omega-3 fatty acids, but eating two servings of fish such as barramundi per week will supply most adults with enough, says the University of Massachusetts Medical School. A diet high in omega-3 fatty acids may help lower your cholesterol and decrease your risk of heart disease, cancer and neurological disorders.

Excellent Protein Choice:
The Centers for Disease Control and Prevention says that the average adult woman needs 46 grams of protein per day, while a man should have about 56 grams. Barramundi supplies 35 grams of protein in a 6-ounce fillet – that’s 76 percent of a woman’s protein RDA and 62 percent of a man’s daily protein requirement. You may have a better chance of avoiding chronic diseases such as diabetes, cancer and heart disease if you get more of your protein from plant-based sources, poultry or seafood, rather than red or processed meats.

Variety of Vitamins and Minerals:
Like all fish, barramundi is a source of a number of essential vitamins and minerals that support your immune, cardiovascular and nervous systems, including selenium, zinc, magnesium, vitamin A and calcium. Each 6-ounce fillet of barramundi contains 40 milligrams of calcium, or 4 percent of the 1,000-milligram daily recommended intake for adults. Barramundi also provides approximately 4 percent of an adult’s required intake of vitamin A.

Health Benefits of Barramundi:
Let’s take a closer look at the health benefits of barramundi.

Low Mercury Levels:
Barramundi is one fish that eats plankton for surviving, unlike other fish that gobble up smaller fish. This makes the palmer a healthier food option for all the fish lovers as the mercury levels in this fish are very low. Moreover, you can relish this fish without any guilt of contributing to its extinction, merely because it relies on the freshwater organism plankton for its sustainability.

Prevents Cancer:
There is a very high level of omega-3 fatty acids in barramundi, which are often considered good, as the body needs a certain amount of HDL or good cholesterol for normal functioning. Omega-3 fatty acids have also been directly linked to lower risk of cancer, making barramundi a very valuable catch indeed.

7 Incredible Benefits of Barramundi

Tuna Fish

Family: Scombridae
Subfamily: Scombrinae
Tribe: Thunnini
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Scombriformes

Habitat: Tuna fish are found in all sorts of habitats (places), including coastal estuaries, lakes, wetlands, rivers, mountain streams and even alpine tarns.

For both long- and shortfins, places to hide (cover) during daylight are very important – water weed, tree roots, undercut banks, and debris piles are all suitable types of cover. They are able to squeeze into very small spaces and dig down into the mud.

Description:
A tuna is a saltwater fish that belongs to the tribe Thunnini, a sub-grouping of the mackerel family (Scombridae). Thunnini comprises fifteen species across five genera, the sizes of which vary greatly, ranging from the bullet tuna (max. length: 50 cm (1.6 ft), weight: 1.8 kg (4 lb)) up to the Atlantic bluefin tuna (max. length: 4.6 m (15 ft), weight: 684 kg (1,508 lb)). The bluefin averages 2 m (6.6 ft), and is believed to live for up to 50 years.

Tuna, Opah, mackerel sharks are the only species of fish that can maintain a body temperature higher than that of the surrounding water. An active and agile predator, the tuna has a sleek, streamlined body, and is among the fastest-swimming pelagic fish – the yellowfin tuna for example, is capable of speeds of up to 75 km/h (47 mph). Found in warm seas, it is extensively fished commercially, and is popular as a game fish. As a result of overfishing, stocks of some tuna species, such as the southern bluefin tuna, are close to extinction.

Nutritional Value of Tuna Fish:
The health benefits of tuna fish can be attributed to the impressive content of vitamins, minerals, and organic compounds found in this delicious fish. [1] These include antioxidants and protein, without much-saturated fat or sodium. It also has impressive levels of selenium, phosphorous, iron, magnesium, and potassium. In terms of vitamins, there is a wealth of vitamin B12 and niacin, as well as a good amount of vitamin B6 and riboflavin.

Health Benefits of Tuna Fish

Heart Health:
Perhaps the most common health benefit that is attributed to tuna fish is its significant impact on heart health.  In terms of reducing coronary heart diseases, tuna fish has high levels of omega-3 fatty acids, which help reduce omega-6 fatty acids and LDL or bad cholesterol in the arteries and blood vessels. Furthermore, it often replaces foods with high saturated fat content, further lowering the risk of heart diseases.

Blood Pressure:
The anti-inflammatory omega-3 fatty acids can help reduce blood pressure. [3] Potassium, found in tuna, is a vasodilator and is very good for lowering blood pressure. Reducing hypertension can significantly boost your health by lowering the strain on your cardiovascular system. This will help prevent heart attacks and strokes, as well as conditions like atherosclerosis.

Eye Care:
Tuna fish, being rich in omega-3 fatty acids, is a great option for preventing eye disorders like age-related macular degeneration. [4] This disease is the major reason behind the occurrence of blindness in the elderly people. The blindness is also caused due to diabetic complications and tuna can help in reducing the chances of diabetic retinopathy.

Growth and Development:
Tuna fish is packed with high levels of protein. [5] A single serving of only 165 grams (approximately 1 can of tuna fish) contains more than 80% of your daily protein requirement. Proteins are the building blocks of our body that guarantee growth, faster recovery from wounds and illnesses, improved muscle tone, and overall metabolic efficiency.

Weight Loss:
Tuna fish is low in calories and fat, yet loaded with beneficial nutrients like protein. The omega-3 fatty acids found in tuna stimulate a hormone called leptin, which balances the body’s food intake with the internal desire to eat more. [6] This can reduce overeating and make sure that your body is only consuming what it actually needs.

Boosted Immune System:
Tuna contains a good amount of vitamin C, zinc, and manganese, all of which are considered antioxidant in nature. Antioxidants are one of the body’s defense mechanisms against free radicals, the harmful by-products of cellular metabolism that cause cancer and other chronic diseases.  However, the real champion of tuna’s immune system-boosting potential is selenium. Tuna fish is rich in this mineral, giving nearly 200% of the daily requirement in a single serving. This makes the fish a very powerful antioxidant and immune-boosting food.

Energy Levels:
The B complex vitamins in tuna have been connected with a wide range of health aspects. [8] They are mainly involved in boosting the metabolism, increasing the efficiency of organs, protecting the skin, and increasing energy levels. By consuming tuna fish regularly, you can ensure that you are active, energetic, and healthy.

Blood Circulation:
Tuna is a rich source of iron, along with the B-complex vitamins that play an important role in red blood cell formation. [9] Without iron, people become anemic and their blood is unable to oxygenate the vital organs that need fresh oxygen to function efficiently.

Cancer Prevention:
Tuna fish has antioxidant properties, thanks to selenium and other nutrients, making it effective at preventing some types of cancer. [10] Numerous studies have connected tuna to a reduction in the occurrence of breast and kidney cancer. Selenium is a powerful antioxidant that neutralizes free radicals before they can cause a mutation in healthy cells, thereby turning them into cancer cells. Other promising results have also shown a reduction in colon cancer, thanks to the high levels of omega-3 fatty acid in the fish.

Kidney Diseases:
The potassium and sodium content in tuna is well-balanced, which helps manage the fluid balance in the body. When your body maintains a fluid balance, the kidneys function properly, thereby lowering the chances of developing serious kidney conditions.

Reduced Inflammation:
Tuna fish can keep the body’s overall stress levels down by reducing inflammation, thanks to the anti-inflammatory vitamins and minerals. [11] A reduction in inflammation across the body ensures an enhanced functioning of all organs. It also helps prevent inflammatory diseases like arthritis and gout, both of which afflict millions of people around the world.

Cell Membrane Damage:
When tuna fish is cooked, the proteins in tuna begin to break down into fragments, called peptides. These fragments can actually be powerful antioxidants that specifically target cell membranes, keeping them healthy, strong, and functioning properly. [12] Free radicals often attack membranes throughout the body, including those in the brain, so eating cooked tuna and improving the membrane protection is a very good idea!

Mercury and Selenium Balance:
Consuming any fish, or for that matter, tuna, above a certain limit can bring the mercury level in our body at an unhealthy point. Studies have shown that there is a unique form of selenium, called selenoneine. This actually binds to mercury and acts as an antioxidant, slightly changing the composition of mercury to make it less dangerous. However, studies are still ongoing to completely validate this.

Depression:
Intake of tuna fish is good for relieving depression. Findings of a research study suggest that fish consumption may be beneficial for women’s mental health. [14] It can also reduce depression levels in women.

Tips for Enjoying Tuna Fish

The taste of tuna fish makes it perfect for eating as a tuna steak, as a spread with mayonnaise on crackers or bread, in tuna salad and burger, or any of the other varieties. [15] It is versatile, delicious, inexpensive, and very good for health.

Cat fish

Binomical Name:  Siluriformes or Nematognathi

Kingdom:: Animalia

Phylum:    Chordata

Class:   Actinopterygii

Superorder:  Ostariophysi

Order:   Siluriformes

Bengali name :Aur mach or Air mach

Habitat:

Extant catfish species live inland or in coastal waters of every continent except Antarctica. Catfish have inhabited all continents at one time or another.  Catfish are most diverse in tropical South America, Asia and Africa with one family native to North America and one family in Europe.  More than half of all catfish species live in the Americas. They are the only ostariophysans that have entered freshwater habitats in Madagascar, Australia, and New Guinea.

They are found in freshwater environments, though most inhabit shallow, running water.  Representatives of at least eight families are hypogean (live underground) with three families that are also troglobitic (inhabiting caves).  One such species is Phreatobius cisternarum, known to live underground in phreatic habitats.  Numerous species from the families Ariidae and Plotosidae, and a few species from among the Aspredinidae and Bagridae, are found in salt water.

In the Southern United States, catfish species may be known by a variety of slang names, such as “mud cat”, “polliwogs”, or “chuckleheads”.  These nicknames are not standardized, so one area may call a bullhead catfish by the nickname “chucklehead”, while in another state or region, that nickname refers to the blue catfish.

Description:

Catfishs  are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat’s whiskers, catfish range in size and behavior from the three largest species, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, Vandellia cirrhosa. There are armour-plated types and there are also naked types, neither having scales. Despite their name, not all catfish have prominent barbels. Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus Corydoras, are important in the aquarium hobby. Many catfish are nocturnal,but others (many Auchenipteridae) are crepuscular or diurnal (most Loricariidae or Callichthyidae, for example).

Catfish have one of the greatest ranges in size within a single order of bony fish.   Many catfish have a maximum length of under 12 cm.  Some of the smallest species of Aspredinidae and Trichomycteridae reach sexual maturity at only 1 centimetre (0.39 in).

The wels catfishSilurus glanis, and the much smaller related Aristotle’s catfish are the only catfish indigenous to Europe: the former ranging throughout Europe, and the latter restricted to GreeceMythology and literature record wels catfish of astounding proportions, yet to be proven scientifically. The average size of the species is about 1.2–1.6 m (3.9–5.2 ft), and fish more than 2 metres (6.6 ft) are rare. However, they are known to exceed 2.5 metres (8.2 ft) in length and 100 kilograms (220 lb) in weight. In July 2009, a catfish weighing 88 kilograms (194 lb) was caught in the River Ebro, Spain, by an 11-year-old British schoolgirl.

CLICK & SEE THE PICTURES

In North America the largest Ictalurus furcatus (Blue catfish) caught in the Missouri River on 20 July 2010, weighed 59 kilograms (130 lb). The largest flathead catfishPylodictis olivaris, ever caught was in Independence, Kansas, weighing 56 kilograms (123 lb).

These records pale in comparison to a giant Mekong catfish caught in northern Thailand on 1 May 2005 and reported to the press almost 2 months later that weighed 293 kilograms (646 lb). This is the largest giant Mekong catfish caught since Thai officials started keeping records in 1981.[26] This species is not well studied since it lives in developing countries and it is quite possible it can grow even larger.[citation needed] Also in Asia, Jeremy Wade caught a 75.5 kilograms (166.4 lb) Goonch following three fatal attacks on humans in the Kali River on the IndiaNepal border. Wade was of the opinion that the offending fish must have been significantly larger than this to have taken an 18-year-old boy as well as a water buffalo.

Piraíba (Brachyplatystoma filamentosum) can grow exceptionally large and are native to the Amazon basin. They can occasionally grow to 400 lbs, as evidenced by numerous catches.

In many catfish, the humeral process is a bony process extending backward from the pectoral girdle immediately above the base of the pectoral fin. It lies beneath the skin where its outline may be determined by dissecting the skin or probing with a needle.

The retina of catfish are composed of single cones and large rods. Many catfish have a tapetum lucidum which may help enhance photon capture and increase low-light sensitivity. Double cones, though present in most teleosts, are absent from catfish.

The anatomical organization of the testis in catfish is variable among the families of catfish, but the majority of them present fringed testis: Ictaluridae, Claridae, Auchenipteridae, Doradidae, Pimelodidae, and Pseudopimelodidae.   In the testes of some species of Siluriformes, organs and structures such as a spermatogenic cranial region and a secretory caudal region are observed, in addition to the presence of seminal vesicles in the caudal region.[30] The total number of fringes and their length are different in the caudal and cranial portions between species.   Fringes of the caudal region may present tubules, in which the lumen is filled by secretion and spermatozoa.  Spermatocysts are formed from cytoplasmic extensions of Sertoli cells; the release of spermatozoa is allowed by breaking of the cyst walls.[29]

The occurrence of seminal vesicles, in spite of their interspecific variability in size, gross morphology and function, has not been related to the mode of fertilization. They are typically paired, multi-chambered, and connected with the sperm duct, and have been reported to play a glandular and a storage function. Seminal vesicle secretion may include steroids and steroid glucuronides, with hormonal and pheromonal functions, but it appears to be primarily constituted of mucoproteins, acid mucopolysaccharides, and phospholipids.

Fish ovaries may be of two types: gymnovarian or cystovarian. In the first type, the oocytes are released directly into the coelomic cavity and then eliminated. In the second type, the oocytes are conveyed to the exterior through the oviduct.   Many catfish are cystovarian in type, including Pseudoplatystoma corruscans, P. fasciatum, Lophiosilurus alexandri, and Loricaria lentiginos

Edible Uses:

Cat fish as Food :

Catfish have widely been caught and farmed for food for hundreds of years in Africa, Asia, Europe, and North America. Judgments as to the quality and flavor vary, with some food critics considering catfish excellent to eat, while others dismiss them as watery and lacking in flavor.[42] Catfish is high in vitamin D.[43] Farm-raised catfish contains low levels of omega-3 fatty acids and a much higher proportion of omega-6 fatty acids.

In Central Europe, catfish were often viewed as a delicacy to be enjoyed on feast days and holidays. Migrants from Europe and Africa to the United States brought along this tradition, and in the Southern United States, catfish is an extremely popular food.

The most commonly eaten species in the United States are the channel catfish and the blue catfish, both of which are common in the wild and increasingly widely farmed. Farm-raised catfish became such a staple of the diet of the United States that on 25 June 1987, President Ronald Reagan established National Catfish Day to recognize “the value of farm-raised catfish.”

Catfish is eaten in a variety of ways. In Europe it is often cooked in similar ways to carp, but in the United States it is popularly crumbed with cornmeal and fried.

Health Benefits of Catfish:

Many people enjoy the flavor of catfish, but it offers a variety of health benefits as well. Including the nutritious fish in your diet helps you meet your protein needs and boosts your intake of vitamins and healthy fats and fatty acids. Consider catfish regularly in your meal planning.

Low in Calories and Fat

A 3-oz. serving of catfish introduces 122 calories and 6.1 g of fat into your diet. The low amount of calories in this fish make it a popular choice for a healthy meal plan – women generally require approximately 300 to 500 calories per meal, and men need around 400 to 600 calories, so it fits in well and allows you to serve several healthy side dishes with it. The fat content is also relatively low, and little of it is saturated fat — 2 g. Avoid consuming more than 16 to 22 g of saturated fat per day; too much in your diet can trigger health problems.

Contains Healthy Fatty Acids

Eating catfish is a tasty way to boost your intake of omega-3 and omega-6 fatty acids. One serving of this fish provides 220 mg of omega-3 fatty acids and 875 mg of omega-6. You will not find federal guidelines on the consumption of these fatty acids, although the American Heart Association suggests including fish in your diet several times each week to increase the amount of fatty acids you eat. Both of these nutrients play a part in heart and cognitive health.

Provides Complete Protein

The 15.6 g of protein in a serving of catfish provides you with all of the amino acids your body needs. This high-quality, complete protein helps your body build lean muscle mass, and it also helps improve the effectiveness of your immune function. You may also rely on protein to provide energy, especially if your body has used all of the carbohydrates you have eaten for fuel.

Source of Vitamin B-12

Consume a serving of catfish, and you take in 40 percent of the daily recommended intake of vitamin B-12. As a B vitamin, the vitamin B-12 in catfish is critical to aiding your body in the breakdown of the foods you eat into usable energy, but this vitamin has other functions as well. Without enough vitamin B-12 in your diet, your nerve function suffers, and you might become lethargic.

Low in Mercury

Almost all fish contains mercury, a contaminant that may impact your nervous system, but you may safely eat catfish unless the waters in which it is caught are particularly high in mercury. The Environmental Protection Agency lists catfish as one of the mostly commonly consumed, low-mercury fish. Despite this, limiting your consumption of fish to 12 oz. per week is recommended to decrease your exposure. This is especially important if you are pregnant, since high levels of mercury may harm your fetus.

Medicinal Uses:

Venomous Persian Gulf catfish excrete a gel-like slime that dramatically speeds the healing of cuts and might spur development of a new preparation to treat wounded humans, a UC Davis researcher believes.

Economic Importance:

Catfish are easy to farm in warm climates, leading to inexpensive and safe food at local grocers. About 60% of U.S. farm-raised catfish are grown within a 65-mile (100-km) radius of Belzoni, Mississippi.

Catfish raised in inland tanks or channels are considered safe for the environment, since their waste and disease should be contained and not spread to the wild.

In Asia, many catfish species are important as food. Several walking catfish (Clariidae) and shark catfish (Pangasiidae) species are heavily cultured in Africa and Asia. Exports of one particular shark catfish species from Vietnam, Pangasius bocourti, has met with pressures from the U.S. catfish industry. In 2003, The United States Congress passed a law preventing the imported fish from being labeled as catfish.[40] As a result, the Vietnamese exporters of this fish now label their products sold in the U.S. as “basa fish.” Trader Joe’s has labeled frozen fillets of Vietnamese Pangasius hypophthalmus as “striper.”

There is a large and growing ornamental fish trade, with hundreds of species of catfish, such as Corydoras and armored suckermouth catfish (often called plecos), being a popular component of many aquaria. Other catfish commonly found in the aquarium trade are banjo catfish, talking catfish, and long-whiskered catfish.

Known Hazards:
A sting from the striped eel catfish, Plotosus lineatus, may be fatal.
While the vast majority of catfish are harmless to humans, a few species are known to present some risk. Many catfish species have “stings” (actually non-venomous in most cases) embedded behind their fins; thus precautions must be taken when handling them.
