dc.description.abstractIn India, trawl is the major gear contributing more than 50% of the marine fish landing and during 2008-2011, the average landing along the Indian coast was estimated at 1.7 million t. In India, fish brought from trawl fishery for human consumption in fresh or processed form is termed as commercial landing and the rest is called low valued bycatch (LVB). The increased demand for LVB from fish meal plants is an emerging threat for marine fish production in the future, since LVB was constituted mainly by juveniles of commercial fishes. The study showed that the percentage of LVB from the trawlers in India increased from 21% in 2008 to 23% in 2011. The results of the study identify some of the fishing grounds and seasons, in which the percentage of juvenile bycatch of the commercial species is very high. Implementing operational restrictions in the fishery in such areas will help in reviving the stock. The paper illustrates the utility of the spatiotemporal data in suggesting seasonal and spatial restrictions in fishing operations in tropical multispecies scenario.en_US
