FORECASTING MODELS FOR TUNA FISHERY WITH AEROSPATIAL REMOTE-SENSING

Tropical tuna movements can be observed from space. We must deduce them by models based on tuna behaviour. To find high concentrations of tunas, we have to find areas with high density of tuna forage. The knowledge of the surface thermal signature of fertilizing processes of water masses is possible using satellite infrared radiometers. We can estimate forage production, and thereby predict tuna distribution. A forecasting model using the concept of the hydrological history of water masses provides a way to find high concentration of tuna. However a new way of investigation is with expert diagnostic systems.
