Quite often, strange behavior of fish is observed in water bodies. She can swim quickly and chaotically near the surface or move slowly from side to side.

At first, it may seem that this is an easy prey that can be collected with a net. However, this is a sign of a worm infestation, so take your time to catch it. Seliter fish is dangerous to human health and can be fatal.

What to do in such a situation? To get started, we recommend reading this article. This article details the methods of dealing with parasites. We also recommend contacting a specialist. Read the article >>>

What is a tapeworm

You can find out what a tapeworm looks like from the photos that are freely available on the Internet. The parasite is a helminth from the Pseudophyllidea group. This worm can grow up to 25 cm long and 2 cm wide. The tapered shape of the tapeworm makes it easy to distinguish it from other helminths.

It looks like an uneven, interlaced white ribbon. Its structure is quite simple:

  • head size 5 mm;
  • a large number of segments - in adults up to 4 thousand.

The segments of the helminth are necessary for reproduction. Eggs are formed in them, which are subsequently discarded into the environment. The parasite is able to recover from just one segment into a full-fledged tapeworm.

Tapeworm life cycle

The life cycle of a helminth consists of several stages.

  1. The worm enters the environment along with feces, which are released by infected mammals. The eggs of the parasite are able to maintain vital activity outside the host's body for a month. During this time, they must enter the body of a further host or die.
  2. Larvae are released from the eggs in the reservoir, which serve as food for crustaceans. They are intermediate carriers.
  3. When a fish eats an infected crustacean, it becomes a new host. The worm parasitizes in its abdominal cavity, gradually developing to a new larval stage.
  4. The main carrier of the parasite is the person who ate the infected fish. Also, the final carrier can be an animal, for example, a cat, a dog. The tapeworm penetrates the intestines, attaches to its walls and develops to a sexually mature individual, which will actively reproduce in the future.

Specimen fish signs

The parasite in the fish is actively growing, so it begins to squeeze the organs closest to it, which leads to their atrophy.

The fish begins to develop intoxication, metabolic problems, the swim bladder loses its hydrostatic properties.

Several ways to identify infected fish that are dangerous to humans.

  1. The fish is not able to dive to great depths. It lingers on the surface of the water, swimming on its side, sometimes on its back.
  2. The belly of such a fish is hard, swollen. If you press on it, you can surprise the segments of the parasite.
  3. During fishing, such a fish is very passive, practically does not offer resistance, and dies quickly.

To be sure that the fish is infected, you just need to gut it. Flatworms are localized in the abdominal cavity, and larvae often parasitize in:

  • liver;
  • intestines;
  • muscles near the fins.

It is impossible to see the larvae without a microscope. The peak of tapeworm infection of fish occurs during the summer period, however, invasion is possible in other seasons.

Which fish are susceptible to tapeworm infestation?

The tapeworm is capable of attacking 47 species of fish. Often, the invasion occurs in river fish, these are:

  • crucian carp;
  • silver bream;
  • pike;
  • bream;
  • roach.



Also, fish infection occurs in ecologically clean regions. Often the parasite is found in salmon, roach, herring, pollock. It should be noted that whitefish, peled, zander are not susceptible to tapeworm infection.

Is it possible to eat saline fish

Some people mistakenly believe that once the parasite is removed from the belly of a fish, it can be eaten. The larvae still remain in such fish, since they are located in muscle tissues.

If they enter the human body, then after a couple of weeks they will begin to actively develop. In some cases, the invasion is asymptomatic. Often, infection causes:

  • nausea;
  • vomiting;
  • dizziness;
  • unstable psycho-emotional state;
  • problems with the digestive system.

It is better to dispose of the seltzer fish and never let it go back into the water. You can simply throw the fish away from the reservoir, since tapeworm larvae do not survive in the ground, unless of course they enter the body of the animal that eats it. It is best to burn such fish.

If, nevertheless, the desire to eat saltiter fish has not disappeared, adhere to some rules.

  1. Send the fish to deep freeze for three days at a temperature not exceeding -20 degrees.
  2. Salt the fish for 12 days. Salt is selected from the volume of fish (12-20%).
  3. Cut the fish into small pieces and cook for half an hour, counting from the start of the boil.
  4. You can also fry the fish on all sides for about 20 minutes.
  5. Hot smoking and baking over a fire also kills the parasite.

If you come across a saltiter fish, it is better to dispose of it and in no case eat it. No amount of precaution will help eliminate the possibility of infection. It must be borne in mind that the larvae of the helminth (even if the adult worms are removed from the fish) can easily get on the kitchen utensils, which causes further infection on the hands.
