“…The Indian National Centre for Ocean Information Services (INCOIS) provides remote-sensing-based potential fishing zone (PFZ) forecasts to fishermen in the islands (Grinson et al 2011(Grinson et al , 2013. The forecasts are based on chlorophyll and SST maps retrieved from ocean colour and thermal imagery, respectively (Solanki et al 2005). The islands are under cloud cover for about eight months of the year, which obscures optical and thermal imagery and hinders the generation of PFZ advisories (Grinson et al 2014).…”

Mesoscale eddies enhance the productivity in a stratified coastal environment by upwelling. The seas around the Andaman and Nicobar Islands have been found to have frequent mesoscale eddy activity. Commercial fishing grounds coincide with upwelling areas associated with cyclonic and anticyclonic eddies and also with areas between two adjacent eddies. There are different eddy zones supporting different types of fishing gears and fish. The current study aims at identifying the different zones of mesoscale eddies in the Andaman Sea and compares the productivity and fishing activity in each of them. Data collected from 454 commercial fishing trips in the Andaman Sea along with maps of sea level anomaly and Moderate Resolution Imaging Spectroradiometer (MODIS) global level 3 mapped thermal infrared (IR) daytime sea surface temperature (SST) from the Aqua and Terra satellites were used for the study. Known upwelling areas such as the periphery of anticyclonic and the core of cyclonic eddies showed higher catches in longlines, ring seines among the fishing gears, and among all the fish species groups. Downwelling areas such as the periphery of cyclonic and the core of anticyclonic eddies showed lower catches with ring seines and the fish species groups. Areas in between adjacent eddies were explored in this study and the fish captures in such areas were found to be different with types of fishing and the target fish group. The study shows results that link eddy activity with the performance of a fishery.

“…Fish populations aggregate in frontal boundaries due to accumulation of planktonic organisms. Relevance of oceanic front with fishery resources has been documented by Laurs et al (1984), Maul et al (1984) and Solanki et al (2001aSolanki et al ( , 2003a. The details of statistical analysis of fish catch data and species distribution with reference to habitat have been discussed by Solanki et al (2005).…”

Ecological associations are the inter-relationship between the species and their environment. Oceanographic processes like upwelling events and formation of eddies, rings, and fronts have been monitored using National Oceanic and Atmospheric Administration Advanced Very High Resolution (NOAA AVHRR) and Indian Remote Sensing Satellite-P4-Ocean Colour Monitor (IRS-OCM) data. Sea Surface Temperature (SST) and chlorophyll concentration (CC) images were derived from AV-HRR and OCM, respectively. Upwelling event was monitored using AVHRR-SST by detecting the differences in surface water temperature. The formation of eddies, rings, cyclonic eddies, and anticyclonic eddies and their biological responses were studied using CC. Eddies and rings were found with high phytoplankton production in the form of bloom, which provide grazing ground for fishes. The anticyclonic eddies were found with very low CC, indicating the biological deserts in the ocean. The impacts of these processes on fish catch were studied using fishing operations data procured from Fishery Survey of India. In this paper, the occurrence of different oceanographic processes, their persistence, and relevance with catch statistics of fishery resources in the study area are discussed. The study explains the potentials of satellite remote sensing to establish the habitat linkage between oceanographic processes and fishery resources.

“…However, the existence of small pelagic fish is still predictable through physical and biological indicators of sea surface environment. Physical processes in the upper ocean influence biological processes and ultimately determine the distributions of pelagic fish (Solanki et al 2005b).…”

“…Chl-a pigment is a convenient index of phytoplankton biomass (Solanki et al 2001) and it could be related to fish production (Bertrand et al 2002). SST is assumed to be an index of the physical environment, which controls the physiology of the living organisms (Solanki et al 2005b) and influences phytoplankton growth (Tang et al 2003).…”

“…The closely coupled physical and biological processes in marine ecosystems varies depending on various space and time scales, and it is represented by sea surface temperature (SST) and Chlorophyll-a (chl-a), respectively (Solanki et al 2005b). Chl-a is known as a very important oceanographic parameter in determining the productivity of the ocean.…”
