Abstract: Trawling operations, extended wide and far, have resulted in the emergence of many non-conventional fishery resources. Apart from regular commercial crustacean resources of shrimps, crabs and lobsters, crucifix crab, C. feriatus, C. smithii and C lucifera are forming bulk catch in regular trawl fishery recently. The south-west coast of India contributes one-third of country’s stomatopod production in which Oratosquilla nepa contributes the maximum. Extension of fishing grounds has resulted in exploitation of larger-sized stomatopods Harpiosquilla harpax, which is edible. Present study aims at understanding the spatio-temporal distribution of these non-conventional resources, through GIS-based resource mapping which is indicative of their distribution and abundance. The study showed that there is good potential for commercial exploitation of non-conventional resources which can form a part of the commercial fishery in coming years to enrich the seafood availability and to provide new avenues for fishermen for maximising their returns from the fishery.
