Growth parameter, Length-Weight relationship and quality coefficient of klunzingeri Mullet (Liza klunzingeri(Day, 1888)) in the Coastal of Khuzestan (Northwest of Persian Gulf)

Biological characters of Liza klunzingeri, in two areas (Sajaphi and Bhrekan) in the coastal waters of Khuzestan were investigated. From March to February 2009, a total 1880 measured fish specimens, 947 specimens were analyzed. The growth indices for males and females studied fishes were found to be L?=20, 24(cm), K=0.83, 1.2 (year-1) and to=-0.15, -0.21 respectively. The length-weight relation were calculated as Y=0.024L2.76 (n=336, R2=0.72) for males, Y=0.011L3.00 (n=596, R2= 0.78) for females and Y=0.0208L2.82 (n=936,R2 =0.82 ) for both sexes. Mean length for the male and female were calculated as 17/97±1/15, 19/11±1/49 and mean weight for the male and female was as73/43±13/71, 85/91±20/95 respectively. The mean Values of condition factor (K) was 1/25± 0/14 in male specimens and 1/21± 0/15 for female specimens. The highest K value in June and the lowest in Febre were observed. According to biological characteristics and with compare to American fisheries society (AFS) indices, Liza klunzingeri is classified as low vulnerable group fishes.
