| description | Study of morphological characters at fish by means of biometry is a frequently utilized method and consists in determining the variability of characters in groups of individuals, by direct measurement, weighting and statistical processing of obtained data.
Effectuation of body measurements and weighting is used to determine the increase in length of fish and to evaluate the general physiological condition. Brook trout, rainbow trout, and brown trout were the object of the current study by analyzing of 50 individuals, 10 individuals in each batch (F1, F2, C1 C2 and I1), from two trout farms from Moldova. After processing the obtained data were calculated the most representative indexes and maintenance coefficients. The obtained values were between 3.49 at batch F1 and 3.94 at batch I1 for profile index; 1.5 at batch I1 and 1.75 at batch F1 for Fulton coefficient; 1.47 at batch F2 and 1.6 at batch I1 for Kiselev index; 41.36 for batch F1 and 47.94 at batch C2 for thickness index; 19.94 C1 batch and 22.08 at F1 batch for fleshy index I, and 19.05 C2 batch and 21.2 at I1 batch for fleshy index II. Having in view the obtained results we can conclude that the analyzed fishes had a good state of maintenance. |
