8.3.2. Advantages of remote sensing in fisheries

• To image large areas at once
• To discreetly observe a range of scales
• To repeat observations frequently
• To make observations independent of weather

Ocean applications of remote sensing

• Locating potential fishing zone
• Algal (Primary production) and other plankton
• Ocean pattern identification
• Fish stock and marine mammal assessment
• Intertidal zone activities
• Wetland mapping and monitoring
• Weather forecasting
• Pollution monitoring
• Oil spill
• Shipping

Prerequisites for the application of remote sensing to fisheries
It requires previous knowledge of

• Habitat preference of the fish
• Biological qualities of the waters
  
• Oceanography of the area
• Behaviour of a given fish at various temperatures, and catch rates obtained under those conditions
