Abstract

Fecundity estimates were made on a total of 92 mature fish of whipfin Silver-biddy, Gerres filamentosus (Cuvier, 1829) of different lengths and weights, collected during the early June of 2010 to October 2010. Log-Log relationships were calculated between fecundity (either absolute or relative) and fish length, fish weight, ovary length and ovary weight. A linear relationship exists between the individual absolute fecundity and fish length or ovary weight. It was found that, absolute fecundity increased at a rate proportional to the power of 4.31115, 1.41549, 1.89836 and 1.122 of the total length, the body weight, the ovary length and the ovary weight, respectively. While the regression coefficients of the relative fecundity estimations for the total length, the body weight, the ovary length and the ovary weight were 3.31115, 0.41549, 0.89836 and 0.0.122, respectively. The observations of the present study showed that fecundity, either absolute or relative, depended mainly on body length and to a lesser extent on body weight, and ovary length. Therefore, fish length is the best expression for fish fecundity and can be used for the prediction of Gerres filamentosus (Cuvier, 1829) production in the Hurghada Red Sea, Egypt.
