| Abstract: | Altogether 1257 specimens collected from April to December in 1987 were studied in this paper by examining the scales for age determination The following two formulas were.used to compute the length-weight relationship of this fish:where L and W represent standard body length and weight respectively.The formula L=51.5096+0.7275R was used to calculate the relationship between body length and scales length.The growth equation is:where Lt is the standard length in mm at the age of t,and Wt is the body weight ( excluding gut gonads) in grams at the age of t215 specimens of gonads of female Harengula nymphaea were studied. |
