Distribution patterns of freshwater prawn, macrobrachium spp. following stock enhancement programme in Sabah, Malaysia

The decline of the freshwater prawn, Macrobrachium spp. in rivers can be attributed to overfishing, habitat loss and pollution. In order to offset the pressure, a community-based stock enhancement project was initiated by Borneo Marine Research Institute (BMRI), University Malaysia Sabah, to increas...
