| Abstract | The objectives of this study were 1) to assess the physicochemical parameters and diversity of plankton, benthos, and nekton 2) to describe the socio-economics of fishers, their fisheries activities, and their perceptions on fisheries resources 3) to assess the current fisheries management system, fishers’ perceptions and suggestions on fisheries management and 4) to provide recommendations for a more practical fisheries management system. This study was conducted in the freshwater fishing area in Pak Phanang River Basin (PPRB), Nakhon Si Thammarat Province, southern Thailand. Spatial and temporal sampling was designed to collect the physicochemical and biological samples. An in-depth send—structured interview using questionnaire was used to collect the socioeconomic data from 161 fishers’ households. Qualitative and quantitative statistics were used to assess biophysical and socioeconomic conditions. The physicochemical parameters revealed that the water in the freshwater fishing area during study period was within the standard range of surface water quality class 2, defined for aquatic organism conservation and fisheries. The diversity indices indicated that the biodiversity was at the medium level and the water was moderately-polluted. However, the parameters and indices varied among seasons (dry, early rainy and heavy rainy) and among sites (upstream, middle-stream and upstream). The major findings of the socioeconomic study indicated that the fishermen are highly concerned over the aquatic environment and fish stock decline which affected their fishing income. It is recommended that fishermen should be more involved in fisheries management particularly regarding regulations and decision-making. Biophysical and socio—economic information from this study can be very useful for managers in formulating appropriate fisheries policies, and for developing awareness, monitoring, surveillance, and participation programs. In addition, the results of this study can be applied for the darn’s operation under HM King’s initiative project in consideration of the aquatic animals and environment in the PPRB. |
