A total of 1582 specimens (772 males and 810 females) were collected monthly from January to December, 2007. The age composition of the sample range between 0+ and 2+in both sexes. The sex ratio was M:F= 1:1.04. The length-weight relationship calculated for all individuals, with W=0.0129 x L2.927. von Bertalanffy growth parameters were for males, L∞=3.31cm, K=0.6597 year-1, to =0.9483 year for females L∞=6.62cm, K=0.2369 year-1, to =0.9259 year for all samples, L∞=5.84cm, K=0.2369 year-1, to =-1.0740 year. A total of 102 stomachs were examined and total of organisms identified from alimentary canal.
