Abstract :

Abstract Some growth characteristics of L.klunzineri were investigated in Bahrekan (east coast of Khuzestan Province) between April 2005 & March 2006. A total of 1880 specimen was sampled, of which 947 specimen was measured & analyzed. Mean value of length for the male and female were calculated as 17/97±1/15 and19/11±1/49 and mean value of weight for the male and female was as73/43±13/71and 85/91±20/95 respectively. Length-weight relationship was calculated as W=0.024L2.76 (n=336, R2=0.72) for males, W=0.011L3.00 (n=596, R2=0.78) for females and W=0.0208L2.82(n=936,             R2 =0.82) for total specimen. Mean values of condition factor (K) were 1.25± 0.14 in males and 1.35±0.15 for females. The highest K value was found in June and the lowest in March. Growth indices for males and females of studied fishes were found to be L∞=20, 24 (cm), K=0.83, 1.2 (year-1) and to=-0.15, -0.21 respectively. According to biological characteristics and comparing to American fisheries society (AFS) indices and Fuzzy logic expert system, L.klunzineri is classified as low vulnerable group fishes.
