Abstract
Information on oceanographic features such as fronts, eddies, gyres, currents and upwelling derived from satellites is useful in fisheries, since fishes usually congregate in these areas for feeding and other physiological requirements. Satellite Remote Sensing techniques can be used to detect fish aggregation by measuring the parameters, which affect the distribution of fishes. Remote sensing is a time and energy saving technique for fishermen to locate fishery resources along the coast. Indian National Center for Ocean Information Services (INCOIS) provides satellite-based potential fishing zones (PFZs) forecasts using the integration of MODIS derived chlorophyll concentration and Advanced Very High Resolution Radiometer (AVHRR) derived sea surface temperatures (SST). In the present study evaluation of fish catch was carried out during 2017 - 2018 using commercial fishing vessels off Veraval coast at 20 to 50m depth in PFZ demarcated and non-PFZ areas using trawl net. The qualitative gut contect analysis was carried out for the fish species found in potential fishing zone and trophic modeling was attempted.
