| Research Abstract |
Relationship between forest structures and biodiversity in mangrove ecosystem was surveyed, and impact of disappearance of mangrove forest on coastal fish assemblage was clarifies in South Thailand. Genetic structure and resource status of fish in Tonle Sap Lake in Cambodia were surveyed and recent changes in fish resource in the lake were clarified. Entry of marginal farmers to local fisheries was suspected be the cause of increase of fishing pressure. There exists slack of the rice production and absence of alternative job as the background of the entry. Production mechanism of extensive fish culture in Lao was studies from viewing point of feeding habit and feeding damage by aquatic insects was estimated. Relationship between salt intrusion and agriculture system and impact of fish culture as an element of integrated farming system on local hygienic environment was surveyed in Vietnam. Process of disruption of local fisheries resources was surveyed in Philippines and it was clarified that establishment of transportation system and increase of fish price caused the entry to the local fisheries from outside.
Conclusively, the low intensive to the management of local resource in local communities where community spirits are weak sometime allows entry of capital, labor forth and technology from outside and cause the destruction of local resources.
