Abstract: India is one of the important marine fish producing countries. Conventionally, for profitable fish catch, fishermen have to spend a lot of time scouting the region using up precious fuel and time as the fish resources are affected by spatial and temporal nature of various environmental factors like temperature, availability of food, currents, wind etc. Due to limited visibility, fishing vessels are unable to see the dynamic nature of environmental parameters on a larger scale that affect the distribution of fish resources. However, satellite remote sensing offers a synoptic view of the ocean in space and time and can provide information needed to assess and locate the probable areas of fish aggregation. In view of this, Space Applications Centre (SAC) initiated and developed an approach to identify and forecast Potential Fishing Zones (PFZ) using remote sensing technique and transferred the technology to Indian National Centre for Ocean Information Services (INCOIS) for operational execution.
