Complete larval and early juvenile development of the mangrove crab Perisesarma fasciatum (Crustacea: Brachyura: Sesarmidae) from Singapore, with a larval comparison of Parasesarma and Perisesarma
The complete larval development of the sesarmid crab Perisesarma fasciatum (Lanchester, 1900) from Singapore was obtained from laboratory culture. All four zoeal stages, the megalopa and the first crab stage are described and illustrated. The morphological characteristics of the larvae of P. fasciatum are compared with those of other known larvae of the genera Perisesarma and Parasesarma. The l...

متن کاملJuvenile Penaeid Shrimp Density, Spatial Distribution and Size Composition in four adjacent habitats within a Mangrove-Fringed Bay on Inhaca Island, Mozambique
The effects of habitat characteristics (mangrove creek, sandflat, mudflat and seagrass meadow) water salinity, temperature, and depth on the density, spatial distribution and size distribution of juveniles of five commercially important penaied shrimp species (Metapenaus monoceros, M. stebbingi, Fenneropenaeus indicus, Penaeus japonicus and P. semisulcatus) were investigated during a high shrim...
متن کاملTheoretical Basis of Allometric Relationships in Juvenile Brachyura: Data from a West African Mangrove Swamp Crab Population
The carapace length-weight relationship in juvenile Brachyura (crabs) was studied theoretically to assess the relevance of the allometric factor and the validity of the condition factor as these factors are often not determined because most fishery investigations are conducted for adult population. The allometric factor appears to be the main parameter in the equation: W = aLb (where W = weight...
