The aim of this study was to calculate the basic population parameters of Trachurus mediterraneus off the coast of the Eastern Black Sea. Average total length was estimated as 13.52 ± 1.884 cm for the entire population, 13.08 ± 1.594 cm for males, and 13.62 ± 1.804 for females. Average weight was 20.27 ± 8.819 g for the entire population, 18.65 ± 7.626 g for males, and 21.31 ± 9.184 g for females. Age of the fish ranged between 0 and 5 years. Length-weight, age-length, and age-weight relationships were estimated for the population, where W = 0.0089 × L^{2.9552}; L_t …

The effect of feeding frequency on nutrient digestibility and growth performance was investigated in rainbow trout (Oncorhynchus mykiss) fed a high lipid diet. The experimental diet contained 25.2% crude lipid and 40.7% crude protein. Two feeding frequencies were tested: 2 meals per day (Group I) and 6 meals per day (Group II). Fish were fed a restricted daily ration (1.5% of body weight) divided into equal meals. t the end of the experiment, the weight gain in Group I and II was 84.6% and 90.1%, respectively. There was no statistically significant difference between groups. The crude lipid and protein digestibility …
