Abstract
In what regards the intensive and super intensive aquaculture, parasites are often the cause of severe illness manifestations. The presence of some dense fish populations, maintained in specific medial conditions, can be favourable for the growth of some parasites species and also can trigger the development of severe illnesses which can lead to a high mortality ratio, with negative aspects on the aquaculture production. The present paper reveals the evaluation of the culture fish parasitological conditions, from the anthropic ecosystem in the Galati county, from the point of view of the illness degree caused by the various parasitosis. Thus, the researches were oriented as to underline the parasitosis which affects fishes in anthropic aquatic ecosystem such as Brates, the spreading area and their evolution.

Key words: parasitosis, anthropic aquatic ecosystem, culture fish
