Many fishermen when cleaning the fish caught were found in her abdominal cavity is long (up to 120 cm) flat white worms (tapeworm). It is the causative agent of legalese or dyremose many freshwater fish — immature forms of tapeworms-flatworms. Mature individuals live in the intestines of fish-eating birds: gulls, grebes, cormorants, herons. This so-called final hosts. In addition, the development of flatworms 2 involves an intermediate host — Cyclops and fish, mainly cyprinids (bream, silver bream, roach, Rudd, roach). Entering the intestine with food, and then, in the body cavity of the fish, the parasites grow, fed by the host, compress the internal organs, causing a violation of their functions.

Caught fish affected by flatworms, after removing them from the abdominal cavity is quite suitable in food. However, meat from sick fish a few different biochemical composition of fish meat is healthy, it is less nutritious and tasty.

To defeat the parasites is simple — you only need to properly prepare the fish. And the dishes made from raw fish can be eaten only under certain conditions:

Bake pies with fish at least 30 minutes.

During salting (up to 2kg) larvae of parasites are killed:

in the hot conditions of the Ambassador (15-16°C) — within 5 to 9 days, in cold salting (5-6°C) — 6-13 days, in conditions of dry salting:

in intact fish after 9-13 days, whipped fish — 7-12 days.
