Abstract
The common silver biddy Gerres oyena is one of the most commercial fish species in the Gulf of Suez. The reproductive characteristics of G. oyenawere investigated in the Gulf of Suez during the period from 2015 to 2016. The overall sex ratio of males to females was estimated at 1: 2.1. Males predominated the small length groups from 10.5 to 13.5 cm, while females dominated the larger lengths >13 cm. The monthly average values of gonad weight percentages and monthly different maturity stages showed that the species spawns during late spring with intensive spawning in May. The length at first sexual maturity was estimated at 13.5 cm for males and 14.1 cm for females which indicates that all individuals over two years of age were sexually mature. The results of this study can be used as a key figure for the conservation and maintenance of this commercially valuable stock in the Gulf of Suez.
