Precision Fishing
Result and Discussion
fFigure 2, and 3 show the sea surface temperature map of the South China Sea off the Peninsular Malaysia coastline. The data on the SST raging from 28oC to 32. 5oC with 0.5C interval is shown. Clearly, the amount of cloud cover require some kind of mosaic of the data of r the whole season to persistent tongues of warm water that extent southward from the north is clear in all the data. This description of warm water intrusion into the south China Sea from the Gulf of Thailand was first reported in the Matahari Expedition report [4].
The thematic maps of historical catch data shown as Figure 4 also holds some interesting observations, Clearly in the first estimation, the correlation between the catch and that of the warm front is very high. Other thematic maps presently developed also show such high correlation between the warm waterfronts and the catch of pelagic fish off the coast of Peninsular Malaysia.
These results are obviously very preliminary. We have yet to determine the presence of upwelling of the coast of Trengganu during the South West Monsoon. The occurrence of the chlorophyll-a concentration and the pattern of sea surface temperature for the South China Sea for the North East, South West monsoon and two other inter-monsoon periods. Much needs to be done before a definite result can be reported.
Studies on ocean color, chlorophyll-a, upwelling and other oceanographic phenomena have yet to be done. This will provide the missing pieces towards assembling this jigsaw of oceanographic date from historical fish catch data and GIS-based decision support system for forecasting fishing grounds.
Conclusion
This major study to develop a real time fish forecasting system for the South China Sea is a bold attempt to assist the nation to achieve its aspirations to develop its offshore fishery and to harvest the fishery resources in a sustainable manner. Preliminary results of the study showed tremendous potential towards achieving the desired objectives. Several major parts of the study still requires detail research and then to be incorporated into the overall scheme of the study. We welcome comments as well as other interest collaborators to work on the project to achieve this potential powerful tool on fishery development and management.
