Distribution and abundance of prawns in a Malaysian mangrove system

Chong V. C., . and Sasekumar A., . and Lim K. H., . (1994) Distribution and abundance of prawns in a Malaysian mangrove system. [Proceedings Paper]

Species composition distribution abundance reproductive maturity and economic value of the prawn community of the Matang Mangrove Forest system in PerakMalaysia were examined. Fifteen species of penaeid and 5 species of palaemonid prawns ere found in the system which comprises a complex network of estuarine rivers waterways and coastal mud flats. Spatial partitioning is apparent among the major prawn species with Parapenaeopsis spp. generally preferring the mud flats and Penaeus and Metapenaeus the river mouths and upriver. Diel variation of prawn catches as influenced by tide and light was observed. Mean population density and biomass for mangrove rivers and waterways were respectively 4092 individuals ha-1 and 7.35 kg h-1 whereas similar entimates for mud flats were respectively 2668 individuals h-1 and 7.19 kg ha-1. The river and mud flat populations comprised 70-98 and 40-90 juvenile prawns respectively indicating the importance of these areas as nursery grounds. The fisheries of the Matang Mangrove Forest system supports an annual commercial production of 21 000 tonnes of prawns valued at US48 million for the state Perak.

Abstract

Species composition distribution abundance reproductive maturity and economic value of the prawn community of the Matang Mangrove Forest system in PerakMalaysia were examined. Fifteen species of penaeid and 5 species of palaemonid prawns ere found in the system which comprises a complex network of estuarine rivers waterways and coastal mud flats. Spatial partitioning is apparent among the major prawn species with Parapenaeopsis spp. generally preferring the mud flats and Penaeus and Metapenaeus the river mouths and upriver. Diel variation of prawn catches as influenced by tide and light was observed. Mean population density and biomass for mangrove rivers and waterways were respectively 4092 individuals ha-1 and 7.35 kg h-1 whereas similar entimates for mud flats were respectively 2668 individuals h-1 and 7.19 kg ha-1. The river and mud flat populations comprised 70-98 and 40-90 juvenile prawns respectively indicating the importance of these areas as nursery grounds. The fisheries of the Matang Mangrove Forest system supports an annual commercial production of 21 000 tonnes of prawns valued at US48 million for the state Perak.
