Age, growth and sex ratio of chub (Leuciscus cephalus L., 1758) in Topçam Dam Lake (Aydın)

Abstract

Sex and age compositions, age-length, age-weight relations, condition factors were investigated on 332 chub (Leuciscus cephalus L. 1758) specimens caught in the Topçam Dam Lake between June 1999 and June 2000. The age compositions of specimens were between I-VII years and sex percentages were calculated as 72.89%for females and 27.11%for males. The forked length and weight of females and males varied from 10.7-26.2 cm, 19.8-344.0 g and 9.7-23.5 cm, 16.2-203.1 g., respectively. Growth of population was the most rapid at the first years of life afterwards growth ratio was slower. Growths were calculated by the Von Bertalanffy the following growth equations were found for females and males, respectively. Lt= 40.18 (1-e 0.121(t+1.575)); Wt= 1188.43 (1-e-0.121(t+1.575)) 3.19; Lt= 27.08(1-e-0.302(t+0.455)); Wt= 272.86 (1-e-0.302(t+0.455)) 2.85. The following equations for lengthweight relationship were determinated for females and males, respectively. W= 0.009082 L3.19; W= 0.022537 L2.85
