DETERMINATION OF PROTEIN FRACTIONS IN THE BLOOD OF THE HIGH ECONOMIC VALUE FISH FARMED SPECIES IN ROMANIA

T. PATRICHE, N. PATRICHE

Abstract


In aquaculture, as in any other sector where work is carried out on live bodies, to get a high production yield depends upon maintenance and monitoring of an unaltered health condition of the biological material. To monitor the health condition of the biological material in a fish farm allows us to establish the preventive measures required to stop the spread of disease and the treatment to be applied in case a mass disease occurs. For this reason to know the value of the total protein and the protein fractions in serum enables us to differentiate the normal physiological condition of the fish material under research, from the eventual pathological modifications having occurred due to the defence reaction of the body. The most part of diseases have but a little influence on the concentration of the total protein in the blood, but some influence on certain protein fractions, and they alter the ratio between albumins and globulins. The level of the total protein in serum is, first of all, a synthetic indicator of the nutritional condition of the body, presenting, at the same time, ample qualitative and quantitative variations depending on species, age, sex, stage of sexual maturity, water temperature and especially in correlation with the health condition of fish. Alterations of the ratio albumins/globulins or of the ratio between different protein fractions have important pathological implications, especially concerning the immunity capacity of fish, a decrease below 0.3 in value of the ratio albumins/globulins in serum being significant for the health condition of fish.
