Abstract

Age, growth, reproduction and feeding habits of brown comber in the eastern Aegean Sea were analysed. Total length and weight of population varied between 6.50-11.70 cm and 3.53-25.80 g respectively. Age was determined by otolith readings and maximum age was observed as 4 years. Including both sexes von Bertalanffy growth equation parameters were expressed as L∞= 12.50 cm, k= 0.54 yr-1 , t0=-1.08. Monthly values of the gonadosomatic index indicated that reproduction starts in March and lasts during July, with a maximum in May. Stomach contents were mainly Crustacea (%IRI= 97.51) and Pisces (%IRI= 2.49).
