Abstract:
Biological characteristics of Madagascar meager, in Choebde and Bahrekan areas, in the east coast of Khuzestan were investigated. During one year study from November 2008 to October 2009 total of 143 fish specimens were analyzed (74 males and 69 females). The Gonadosomatic Index (GSI) for the male and female were calculated as 0.66± 1.29 and 2.83 ± 2.42 respectively, with the highest value in August. The length-weight relationship were calculated as Y=0.042L^2.70 (n=74, R2=0.86) for males, Y=0.061L^2.61 (n=69, R2 =0.85) for females and Y=0.059 L^2.62 (n=143,R2= 0.86) for total fish. The growth indices for total studied fishes were found to be L∞=161.61 (cm), K=0.57 (year-1) and to= -0.17. According to biological characteristics and compared to American fisheries society (AFS) indices, Argyrosomus hololepidotus is classified as highly vulnerable fish.
