Tips for choosing
In order for the useful properties of a catfish to appear in all its glory, it is important to choose it correctly.
- The main indicator of quality - clean bulging eyes. In fresh catfish, they are not muddy or hollow. That is why unscrupulous sellers remove fish eyes before putting it on the counter.
- Gills should be without mucus, red or pink, have only a natural fishy smell. In stale condition, they get a beige or brown shade - a sign of stale goods (fish for at least a week).
- Swollen or covered with mucus belly - a clear indication of poor product quality and violation of the rules of storage.
- High-quality fish is slippery and does not stick to hands, when pressed quickly returns to its former forms (dents should not remain). Otherwise, they are trying to sell you a stale catfish.
- Tight-fitting glossy and smooth scales are another sign of quality.
If you can not buy fresh catfish and have to be content with frozen, check the packing date. It is not recommended to take fish frozen more than two months ago. Useful properties of this product have already begun to get lost.
Keep catfish needed properly. Fresh carcass is not kept in the refrigerator for more than a day. It is better to cook it immediately after purchase. Frozen fish can be placed in the freezer, but for a period not exceeding two months from the date of freezing.
Catfish - very useful fish, subject to the rules of storage practically does not exhibit harmful properties.
The use of catfish motley in cooking
The motley of catfish is white and has a delicate, pleasant taste. Its main difference from meat of other species is that it is dense. If the meat of other catfish is more gelatinous, and you still need to tinker with it before cooking, the motley fillet has an elastic texture.
This meat is suitable for cooking a variety of delicious fish dishes, ranging from fish soup, ending with a delicious casserole.
Differences from other catfish
Catfish are of five species, and blue (other names are blue or blue-green) is only one of the varieties. All of them are somewhat different from each other, and in the store, theoretically, other varieties can also be sold, so you should understand the difference.
The easiest way to distinguish a blue catfish is, naturally, in color - it is blue without pronounced inclusions of other shades, which differs from the spotted variety, whose name speaks for itself - it is variegated and even striped. The so-called common catfish is also usually striped, and the color is different - it is rather brown or gray. Two more species, Far Eastern and Eel-like catfish, are practically not consumed - they can be interesting except for small peoples of the North, and even more so for the skin, not meat. What is interesting is that the blue catfish moves rather late in the water layers, captured by minesweepers, because in the catch it usually is not less than 60-70 cm long. This means that such fish lives for quite a long time and does not come across at a young age - depending on the region of distribution, it must be at least seven years old to achieve this size.
In fairness, there are many types of fish that would be better than blue catfish. No wonder she appeared on the shelves relatively recently and is so cheap, because a few years ago, industrialists simply did not harvest it, using it as bait for halibut or simply throwing it overboard. The reason for this attitude lay in the fact that too juicy and fatty meat seems even slightly watery and liquid. Over time, this product was learned to appreciate for the high content of vitamin A, as well as for some dishes like soup, which are perfectly obtained from this fish.
Blue and colorful catfish fish - useful and harmful properties on the human body
Fish catfish is a member of the perciformes order family Anarhichadiae. The appearance of the fish is extremely frightening. Reminds eels and moray eels. Most of the representatives are very valuable for fishermen. Despite its appearance, it is very tasty.
A common factor in all representatives of this species is a long body of large size. As well as large front teeth. In addition to the front teeth, these fish also have rear and side, with which they crush food. Their jaws are very powerful. Once a year, teeth change to new ones. It is for its terrible protruding teeth that this species got its name.
Adult representatives of the species have sizes from 1 to 2 meters and can weigh up to 30 kilograms, but on average they weigh about 20 kilograms.
Among this species there are several members of the family:
- catfish - this type of catfish lives mainly on the coast of North America near Alaska,
- Far Eastern catfish - the range of this fish is the Far Eastern part of the Pacific Ocean,
- blue catfish - got the name for its color, which can vary from gray to dark blue. It lives mainly in the North Atlantic Ocean,
- striped - It is one of the largest representatives of catfish, it reaches about 20 kilograms in weight, and in length can reach one and a half meters. It lives in the waters of the White and Barents Seas. Lives mainly on the bottom. As well as a distinctive feature, for which it received its name, are black stripes on its side,
- spotty - the largest representative of catfish. It is also called the "two-meter giant." Lives predominantly in the northern seas. Name received for black spots on the sides.
Lifestyle and nutrition
Having reached a mature age, the blue catfish lives mainly on the bottom, where it finds various shelters for itself, where it hides in the daytime. It is a very aggressive fish: protecting its home, can attack any fish, even a representative of its own species.
At an early age, a representative of this species lives mainly in the open part of the sea. When the warm season comes, she likes to be in shallow water, with the onset of winter moves to the bottom.
According to ancient legends, the Far Eastern catfish loves to feed on shipwrecked sailors. But modern researchers have dispelled this myth, although it can really bite through human flesh. But these fish use their teeth mainly only to tear off any objects from the bottom. And they can also split various shells.
The food is used mainly by small inhabitants of the seas like: jellyfish, crayfish, mollusks and other fish. When the catfish change their teeth, they switch to softer food, but then they return to the old food.
По результатам исследований, учёные выяснили, что зубатки являются моногамными, ведут размножение лишь с одним партнёром на протяжении всей жизни. Fish reach puberty at the age of four years, although females reach maturation a little longer than males.
During spawning, the female lays at a time about 30 thousand eggs, which are about 7 millimeters in size. The female larvae lays mainly on the bottom between the stones. After spawning, both parents guard their future offspring.
Young representatives of catfish are born in early spring and have sizes up to 20 millimeters in length at birth. After birth, the larvae immediately swim as close as possible to the surface, where they are looking for food.
As soon as the larvae grow to the size of 6 centimeters, they begin to sink to the bottom and already lead a habitual way of life for representatives of their species.
