A total of 836 samples were monthly collected from two fish landings of Bahrekanand Hendijan; 727 specimens were studied from point of sex determination, and 60specimens were studied from the fecundity point of view. This species was found tohave more abundance in autumn (esp. Oct-Nov). The samples composed of89 (12٫2٪) male, 467 (64٫2٪) female and 171 (23٫6٪) immature; the sex ratio wasM: F = 1: 5. The advanced stages of maturity (4th & 5th) were found in Octoberonward. The highest Gonadosomatic Index was in December and the lowest was inJune. The maximum absolute and relative fecundities were 183040 and 2232, respectively; the minimum absolute and relative fecundities were 44700 and 582, respectively. The minimum and maximum egg diameter was 0٫04mm (stage 2nd) and0٫75mm (stage 6th).
