Economic Fish Larvae Mapping and Monitoring

Marine Fisheries Research and Development Bureau, Department of Fisheries (DOF)

DOF is collecting data on nutrients, water quality and amount of fish larvae by research vessels. These measurements are taken 4 times per year. This frequency is insufficient as ocean changes are more rapid and dynamic. At present, with the data available from fishing vessels larvae distribution is interpolated in controlling fishing ground for certain time of the year to protect and management fish larvae. If it is possible to use satellite data for estimate related parameters to larvae, then it is possible to provide more accurate and frequent distribution maps of fish larvae, helping sustainable fishing industry of Thailand.

The objective of this Prototype is the followings;

1) Establishing relationship of fish larvae and ocean environmental parameters observed from research vessels

2) Establishing relationships between SST, chlorophyll and salinity between vessel data and satellite data, primarily MODIS data

3) Develop a model based on the results of 2 & 3 above

4) Applying the results into fisheries conservation planning process at DOF
