Abstract/Description: | Geographic Information System (GIS) has become a part of our day today life in empowering institutions to formulate acceptable solutions in societal issues. More recently, public participatory GIS (PPGIS) and participatory GIS (PGIS) were viewed as more efficient tools in solving social and resource conservation issues, which empower communities those who are often ignored in traditional GIS practices. In fisheries, PGIS concept was first reported from Canada and on these lines pioneering efforts of involving concept of PGIS in fisheries is being attempted in Karnataka, where the geospatial data on fishing, catch and samples of fish caught by commercial fishing vessels were shared with the research organization and the data and samples thus shared were processed by fishery and GIS experts to come out with various tools for fishery management and resource conservation of the region. The study showed that the trawlers from Mangalore carried out trawling operations from sea off Calicut in the south (75 oE, 11 oN) to off Ratnagiri in the north (73.5 oE, 17 oN). Their depth of operation was between 5 m and 167 m, which signify the importance of revalidation of state–wise policies in introduction of mechanized vessels based on the landing in the respective states. The study showed that during the period, 237 species / groups of marine fauna were discarded of which many were juveniles of commercial species and rest were of adult size fishes of low or no market value. Spatio-temportal distribution and abundance of commercially lesser known species, which was not reported earlier from the coast,which have high trophic importance like small crabs, Charybdis hoplites and shrimp species like Metapenaeus andamanensis were brought out as the results of the study. Study also provided information on a unique ecosystem off Karnataka coast and with reef species and there is an immediate need for conserving this ecosystem. Based on the results of distribution and abundance of marine resources, spatial and seasonal restrictions on fishing efforts can be advocated in areas and seasons during which high incidence of bycatch of juveniles and non-commercial biota is being caught. This will help in sustaining marine fisheries from Malabar and Konkan coasts. |
