Parasites known as living organisms that exist at the expense of other creatures.Speaking of fish, highlight endoparasites.This so-called protozoan parasites that live in the fish.

very word denoting living someone else's expense, sometimes colloquially used as a curse word.Indeed, in translation it means - "freeloader."Indeed, the parasites in the fish feed on the flesh (eg lamprey) or blood creatures - their carriers, weakening the "owners", making susceptible to various diseases.In addition, they often destroys the internal organs of creatures.

parasites in fish may be tiny, as small as 5 microns.But these tiny protozoa sometimes cause fatal harm to their "masters."

disease called cryptobiosis cause flagellates of the genus Criptobia.These various parasites in fish resemble each other in appearance, but the symptoms of disease caused by them are extremely different.

Branhiopatichesky cryptobiosis was introduced by us from China with carp.The tiny parasites (14-23 microns) prefer to live and develop in the fish gill filaments, preventing her breathing.

First, the affected fish gills strongly redden, and the body itself loses its color, covered with abundant mucus.It becomes lethargic, refusing food and shows signs of choking: often floats to the surface, grasping for breath.Later, the body is very dark.

cure fish in a big pond nature is almost impossible.But it is extremely disappointing if suffering from rare instances of aquarium fish.Then we must take urgent action to prevent die all the inhabitants of the aquarium.

if simply been placed in an aquarium with infected fish or plants, very soon the first signs of the disease will be felt.All the fish in this case it is necessary to land in a separate vessel, where the first day of their treated with copper sulfate solution at the rate of 1 gram per bucket for 20 minutes.

second day fish treated with formalin, making the solution at the rate of 2.5 ml per bucket and maintaining pupils in it for half an hour.On the third day of the treatment make the fishes 'bath' with the addition of "malachite green", where they were placed for 5 hours.The solution is prepared at the rate of 0.006 g per bucket.

then floating "patient" can be returned to the general aquarium, where during this time all the parasites have already died from hunger.After the temperature in the general aquarium should be raised to 25 degrees - the most appropriate mode for the activity of these tiny pests.Unable to find the owner, and, therefore, deprived of the opportunity to eat, just dies.

But human health simply do not have the damage.It is much worse for people multicellular parasites of fish - worms, living in the belly, in internal organs or muscle tissue.The eggs of these parasites with or insufficiently cooked fish neprozharennoe get into the body and begin their life cycle.This disease is called opistorhoz.As a result, a person-support affects the liver, pancreas, and biliary tract.

parasites living at the expense of fish, it is extremely diverse.Along endoparasites described above, there are more ectoparasites - those who eat fish flesh or blood, without penetrating into the animal.These are various crustaceans, ticks, leeches, lamprey and fleas.

interesting specimens is the flea, which clings to the tongue of the fish.Gradually, the body dies, and it takes place a parasite that, while continuing to eat the blood of fish, at the same time in her life performing the role of language.This phenomenon, when the parasite performs the function of the destroyed their authority, was opened recently and just shook people!This had not yet been observed once.

To protect themselves from diseases that are caused by parasites in the fish population must be remembered that in any case can not eat raw fish.
