Abundance and Reproductive Biology of the Penaeid Prawns of Bagamoyo Coastal Waters, Tanzania
MetadataShow full item record
The coastal waters of Bagamoyo in Tanzania constitute an important penaeid prawn trawling ground. Despite the high economic value attached to this resource, the biological information necessary for its sustainable exploitation is scanty and fragmented. The present study was therefore designed to investigate the species composition, population abundance and reproduction of the penaeid prawns in Bagamoyo coastal and nearshore waters. Samples were obtained monthly for a period of one year from inshore waters adjacent to the Ruvu Estuary while additional samples were bought at the beach from artisanal fishermen. In the laboratory, samples were identified to the species level. Four penaeid species, Fenneropenaeus indicus (formerly known as Penaeus indicus [Farfante and Kensley, 1997]), Penaeus monodon, P. japonicus, and Metapenaeus monoceros were found in the Ruvu Estuary and nearshore waters. Fenneropenaeus indicus was the most abundant, and more so during the rainy season than th.....
