GIS-Based Model for Economic Marine Mollusc Production and Coastal Aquaculture Management in Pattani Bay:

Supat Khongpuang: Ph.D.

Pattani Bay, and its adjacent area is a relatively small bay in the southern most part of Thailand. It is used intensively for many purposes; fish processing plants, urban and community settlement, coastal aquaculture (shrimp farms, cockle, mussel, sea bass and seaweed culture), communal/industrial waste water treatment area, fishing grounds, and a mangrove reserved area. Focusing on marine molluscs, the bay and nearby area (74 km2 in total water area) has at least 90 species, wat least 10 of which are of economic importance. Among the various uses, some conflicts are inevitable. GIS–based modeling is one of the possible technologies that can be used as a part of the Pattani bay sustainable fishery resources management. Initially, the project will develop a “GIS-Based Model for Economic Marine Molluscs Production and Coastal Aquaculture Management in Pattani Bay”. In summary, marine molluscs distribution will be mapped, a model for some economic mollusc production estimation will be developed as well as some cultured species that are mentioned above. Based on the bay ecology and the current land use activities, some additional models, which relate to and negatively impact, coastal aquaculture (sea water and fresh water intrusion, and waste water distribution) in the study area would be included.

The overall objective is to develop a GIS-Based Model for Economic Marine Mollusc Production and Coastal Aquaculture Management in Pattani Bay to use as a part of the integrated bay management plan that could be applied to other bays, lakes and/or other semi-enclosed areas in ThailandThe proposed outputs are:
