Wild Sea Perch

If one wants to taste this fish, it is necessary to get information on where it is brought from. Chilean Sea Perch is characterized by high content of mercury that is why a grown up should eat it no more than two times per month. Also, it is better not to buy perch that is caught close to the Crozet Islands, Prince Edward Island and in Chile (https://livecustomwriting.com/blog/summer-vacation-essay-or-have-a-good-rest). In these regions fish is caught without any control, and at the same time a lot of other sea creatures are being killed.

Always ask whether the product is certificated.

The Tilefish

Some of the experts say that this fish should be removed from the ration at all. The tilefish is another fish that has high mercury content in its meat, so its use should be limited. Besides, tilefish catching is often connected with the essential norms violation, which happens because of the exceeding of the permitted level of this kind of fish catching. It provokes the risk to get too roasted fish or spoiled one. If still one is going to serve the tilefish, then it would be better to prefer that fish, which is caught in the middle Atlantic. There they practice more gentle methods of fishing.

The Orange Roughy (Deep Sea Perch)

It is interesting that the age of the roughy can reach one hundred years, but in spite of the incredibly long life term the amount of this fish is very limited because of the long reproductive cycle and poaching. Although, fishing in the ocean is strictly regulated now, the population of the orange roughy has not restored after the “popularity explosion” of the fish a couple of dozens of years ago. People should refuse to buy deep sea perch due to environmental protection reasons at least. Besides, taking into consideration average age of caught fish individuals, it becomes possible to suppose what level of poisoning with toxic substances they have.

Most of the fish and shellfish species accumulate in their tissues Mercury compounds, which can cause serious damage to human central nervous system. The number of these compounds is various depending on the fish kind and its place in the food chain. Mercury being among the compounds of precipitation pollutes natural waters, where it is absorbed by sea plants and later by small fish and further up the chain. In the transferring process from one fish to another mercury is accumulated, and that is why its maximum level is discovered in big predators. Shark is one of them. And there is more, today the population of this fish kind has reached the lowest level in history, because most of them are being killed while other fish catching.

Swordfish is an important object of ocean fishery. It is highly appreciated by chefs all over the world because of its gentle taste and almost absolute absence of bones. Swordfish is often eaten raw. Its meat is being sliced and poured with sauce based on lemon juice. The biggest danger for ordinary consumers is the high cost of the fish. Due to this fact in the stores they often replace this fish with cheaper and not always caught according to norms other kinds of fish. For example, under the guise of swordfish they often sell palombo from shark family. They really have similar taste, but the harm of the last one is much higher.

Due to rapid reduce of the fish amount, on the markets they start to replace the lutjanus with more affordable fish kinds. Thus, they often use Tilapia and Sea bass.

Sushi Shops

Buying in a shop sushi or rolls, everyone should take into consideration that most of them are made of the fish that can be called of the highest quality. Tuna, for example, is often processed with carbon monoxide to make it have red tasty look and to prolong its shelf life.

Freshness of fish can be seen by its outward look.
