Abstract

Barbus are valuable fishes in THE CASPIAN SEA, and BARBUS CAPITO is one of the commercial species. In the present research, a total of 207 specimens from 25 sampling stations in GILAN PROVINCE coasts in the years 2001-2002 were biologically studied in terms of their growth, REPRODUCTION and feeding. The following biological factors were recorded and analyzed: Length-weight average variations in different age and sex groups, length-weight relationship, growth coefficient, gonadosomatic index variation, sex ratio, average fecundity, sexual maturation stages, gastrosomatic and fatness indexes, relative length of intestine, stomach vacuity index, hepatosomatic index, accumulation of fat around digestive tract. Relation between length and weight was logarithmic; the L ∞ was found to be 73.7 centimeters and the growth coefficient was equal to 0.3254. Sex ratio of male to female was 3:1 gonadosomatic index peaked in REPRODUCTION season and was related to feeding intensity and hepatosomatic indexes. Relation between feeding intensity index and gastrosomatic index was direct, while to vacuity index was inverse.
