Abstract

Age, growth, gonadosomatic index and condition factor of poor cod, Trisopterus minutus capelanus were evaluated from 593 specimens collected in Edremit Bay, the northern Aegean Sea between the years of March 2015 and February 2016 by the hauls of trawls. Total length ranged between 10.7-19.8 cm and 9.6-17.0 cm while weight varied between 9.34-95.59 g. and 8.13-51.45 g. in females and males. The male and female ratio was 1:0.42 (M:F) in the favor of males. The von Bertalanffy growth equations (in length) were found as Lt= 23.5 (1-e-0.52(t+0.50), Lt= 32.09 (1-e-0.23(t+5.83)) and the estimated b values were given as 3.0665 and 2.9655 for females and males, respectively. The condition of the fish increased during autumn. A long spawning season (about 4-5 months) in late winter-early spring occured in the population. Analysis of the diet composition showed that poor cod is carnivourus and the food spectrum of L.sceleratus consists of fishes 85% crustacea, 15%digested items, and others 2% (unidetified item). In the view of taxon düzeyi, Alpheus glaber and Liocarcinus sp. are found to be the most items in its feeding habits. Poor cod has an economic value for Turkish Seas and it is also important in the view of biodiversity.
