dc.description.abstractMorphological changes in the embryos, egg size and development, incubation period and morphological structures of newly hatched zoea of three mud crab Scylla species were determined. The three species exhibited similar embryonic development composed of 10 stages. The mean egg diameter of Scylla serrata was significantly larger (P<0.05) at the prehatch stage. The mean egg diameters of Scylla tranquebarica and Scylla olivacea were similar (P>0.05). The incubation period was the longest in S. serrata and the shortest in S. olivacea. There was a positive relationship between egg size and larval size, as S. serrata exhibited the largest egg size and first zoea. However, no correlation was detected between egg size at prehatch and lengths of the morphological structures of the newly hatched zoea. The three species exhibited similar lengths of cephalic structures, but S. olivacea had significantly shorter (P<0.05) abdominal structures. The duration of spawning from ablation was the shortest in S. tranquebarica and the longest in S. olivacea. The study is relevant to aquaculture and fisheries management of Scylla species.en
dc.description.sponsorshipThis study was supported by the Department of Science and Technology (DOST), through its Accelerated Science and Technology Human Resource Development Program, which is facilitated by the DOST – Philippine Council for Aquatic and Marine Research Development. The first author thanks the Aquaculture Department of the Southeast Asian Fisheries Development Center for allowing the study to be conducted in its Crustacean Hatchery (CH) and to the CH sta¡ for their technical support.en
