| Abstract | The interaction between fish distribution and oceanographic conditions has consistently influenced the fish species present in the waters off the west coast of India, especially during the biologically abundant post-monsoon season. In this study, important pelagic fish (Oil Sardine, Lesser Sardine, Anchovies, Indian Mackerel and Horse Mackerel) and environmental variables from 2018 to 2023 were examined, including upwelling indices, sea surface temperatures (SST), sea surface salinity (SSS), surface currents, and Chlorophyll-a concentrations. Focus was paid to the role of the West India Coastal Current (WICC), which has seasonal reversals and influences nutrient transport, salinity gradients and dispersal of larvae along the coast. To understand the seasonal and inter-annual variations in fish landings for the west coast of Indian states from Gujarat to Kerala, we devised a multi-source dataset framework which included Global Fishing Watch effort maps, fish landing data from CMFRI reports, satellite-derived Chlorophyll from ocean colour datasets, Copernicus ocean reanalysis for currents magnitude (vectors) and Optimum Interpolation Sea Surface Temperature (OISST) for temperature. This study improves prior knowledge of the distinct and predictable habitat preferences of the species on the fishing ground and the climate impacts on the ecosystem, which in turn facilitates planning for sustainable fisheries. Such results, in turn, augment planning for regional economic development, potential fishing zone (PFZ) optimisation, and sustainable fisheries management. |
