Reproductive biology of the sergestid shrimp Acetes indicus (Decapoda: Sergestidae) in coastal waters of Malacca, Peninsular Malaysia
The sex ratio, maturity, and spawning season of the sergestid shrimp Acetes indicus were determined by analyzing samples collected from coastal waters of Klebang Besar, Malacca between Apr. 2006 and Mar. 2007. The overall annual sex ratio of A. indicus was found to be 1: 2.10 (males: females). The a...
