dc.description.abstractIn this study, studies on growth and reproduction biology and mortality rates, chemical composition of meat in terms of nutritional value were reviewed and the results presented as a whole in the scope of population dynamics of whiting fish (Merlangius merlangus euxinus) living in Black Sea. The regression equation of log (a) against b for different weight length relationships of whiting is Log (a) = -0.0013 (b) +1.735; r(2) = 0.998 (n = 6) for male and Log (a) = -0.0013 (b) +1.650; r(2) = 0.994 (n = 6) for the female. It was determined that the reproductive activity intensified during the summer months of the whiting continued throughout the year. It was determined that whiting meat protein contents is about 15.5 +/- 0.85% and fat ratio is about 1.5 +/- 0.54%. The results showed that the whiting, which grow as fast as the sex maturity, was under the fishing pressure and the fishing with bottom gill nets and mesh size of gill nets are suitable for whiting sustainable fisheries. It is appropriate that the fishing pressure applied on the whiting fish is high (E = 0.75 +/- 0,031) and the fishing mortality rate should be reduced to 50-60% levels. This can be achieved with no fishing, or less fishing of whiting at zero and one year old fish that have not reached sexual maturity.
