Study on population, natural hybrids and induced hybridisation of mud crab (scylla spp.) in Malaysia

Abstract

There are four species of mud crab under genus Scylla, namely Scylla serrata, Scylla tranquebarica, Scylla paramamosain and Scylla olivacea, with one report of natural hybrid (between S. serrata male and S. olivacea female) in Japan. Previous studies on mud crab reported that only three species are found in Malaysian waters, excluding S. serrata.
