Abstract

To estimate the empirical relationships in anchovy, the instantaneous natural mortality rate (M) calculated from von Bertalanffy Growth Function (VBGF) parameters, maximum total length (Lmax) and sea surface temperature (T,°C) were reviewed in the Black Sea. Empirical equations were presented for evaluation of M data in their relationships to VBGF parameters, T and Lmax. Based on biological consideration and regressional definition, it was recommended to use following formulas for estimating of natural mortality rate of small pelagic fish such as anchovy. M = 0.3237 + 1.3174*(K) - 0.0036*(L∞) - 0.0117*(T); M = 0.2639 + 1.3676*(K) - 0.0003*(Lmax) - 0.0124*(T).
