Description:
The reproduction of Pagellus acarne caught in Oran Bay was studied. The samples used were sorted monthlyfrom commercial catches of coastal trawlers operating in this area from April 2008 to July 2009. The overall sex ratio wasin favor of females 1:1.27 and length frequency distribution according to sex revealed that the females were highlyrepresentative beyond 20.5 cm of total length presuming a sexual inversion already described for this sparidae. Theestimated lengths at maturity (Lm) were 12.8 cm for females and 16.0 cm for males. Two spawning periods were made outby the follow-up of the gonado and hepato somatic indexes: a spring period from April to June with a peak in May and anautumnal period, between November and January with a peak in December. The closed season in Oran Bay extends from 1stMay to 31th August, which is to our opinion insufficient to safeguard the renewal of the resource and its spawning stock.
