Abstract :The growth and reproduction of brown comber insert ignore into journalissuearticles values(Serranus hepatus Linnaeus, 1758); were studied using specimens collected from the central Aegean Sea between July 2004 and June 2007. A total of 2410 specimens were analyzed, and of those, 2290 individuals were mature and 120 individuals were juvenile. Analyses covered all individuals because the species is a simultaneous hermaphrodite. The length-weight relationship was determined as W = 0.013L3.11, indicating a positive allometric growth for all samples. The estimated von Bertalanffy growth parameters were L\infinity = 13.19 cm, k = 0.252 y-1, and to = -0.630 y, and the infinite weight insert ignore into journalissuearticles values(W\infinity); was calculated as 39.38 g. The growth performance index insert ignore into journalissuearticles values(j`); of the stock was calculated as 1.642. The first reproduction length was found to be 7.76 cm, corresponding to 3 years of age. The spawning period of the species was determined between May and October.
