Fish fish strife

Fish is a valuable and sought-after, and for many also the most favorite food product. From it you can cook a lot of delicious, tender, easily digestible, delicious, healing dishes.

And more and more people are ready to eat fish not only on the same "fish" day - Thursday, but much more often.

If you ask yourself the question: which of the fish is the most useful, then there will be only one answer - the sea! And fat and caught in the wild.

Why not river? Because the state of river ecosystems, especially shallow ones and those that flow near human habitats, is catastrophic. They are dirty and lifeless.

The “diagnosis” of the waters of the oceans is not much more comforting, but there the highest concentration of harmful and destructive substances is observed for the most part along the coastline.

Fishing, on the other hand, is usually carried out in deep water, far from the coast, so the catch has a satisfactory ecological cleanliness.

Another unpleasant thing for a person who wants to eat right and healthy is the fact that the fish that fills the windows of shops and market stalls, despite its external attractiveness, is far from healthy.

All this is an assortment of fish farms engaged in artificial breeding different varieties fish.

For fattening such fish, growth stimulants, dyes, antibiotics, hormones and other components that are terrible for the human body are used.

In this regard, you need to be very well versed in fish, so that in an effort to get the most useful, you do not have to pay for a synthetic salmon carcass.

What is the most commonly farmed fish?

1. All types of sturgeons, since most of them are included in the Red Book lists and there is no such catch in the wild.

2. Almost the entire list of salmon fish, and especially trout and salmon.

3. Dorado fish.

4. The famous sea bass (it is also on the lists prohibited from catching in nature).

5. Carps, carps, silver carps - although not sea fish, they are tasty and fatty, but, unfortunately, they are also grown on artificial feed.

6. The lion's share of seafood (mussels, shrimp, scallops, lobsters with langoustines, oysters).

7. Telapia fish and pangasius fish. About them in general separately. Not only are these types of fish already considered scavengers and scavengers, they have also begun to be bred in industrial aquariums.

Moreover, for the growth rate and weight gain, they are treated with male sex hormones.

Fish that are still wild
