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

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.
