3.1 INTRODUCTION
Identifying the potential fishing zones (PFZ) is very useful as it minimizes the time and fuel spent on searching the fish resources. In the present study, the annual chlorophyll a and sea surface temperature variations in east and west coast of India was investigated using Moderate Resolution Imaging Spectroradiometer (MODIS) ocean color data and it was correlated with the fish catch data. The results of the study indicated that the chl a concentration ranged from 0.1 to 60 mg m-3 and SST from 17 to 28°C in both the coasts. Chlorophyll a concentration was twice higher in west coast as compared to east coast throughout the study period. There was a positive relation between the total fish catch and chl a in both the coasts, which can be used for predicting the fish catch thereby reducing the fuel spent on searching fish shoal.
