Transparent predator. The most terrible inhabitants of sea depths — Fish Ghost
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:
• it must be fish farmed, fed artificial feed, treated and controlled for the absence of parasites ; • if it is a marine fish found in the ocean, it has to besomething immediately on a fishing vessel frozen and defrosted immediately before consumption; or it should be eaten immediately after harvest; • fish in the river in almost all species can be parasites dangerous to humans (except sturgeon). So, for example, sterlet and sturgeon may be eaten raw. While other species of fish should be salted, pickled or smoked in accordance with the developed recommendations.
Safe well cooked or deep fried fish. The regulations apply to all fish, so as to distinguish by eye if it has microscopic larvae (which, once in the human body, there will turn into adult worms), it is impossible.
Cooking the fish should be 15-20 min after boiling.
Frying — at least 15-20 minutes (the big fish is pre-cut along the ridge on the layer).
Bake pies with fish at least 30 minutes.
When hot and cold smoked fish will be cleaned completely by the time of readiness.
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.
