Use of spatio-temporal data in reducing low value bycatch in trawl fisheries A.P. Dineshbabul*, Sujitha Thomas' and A.C. Dinesh2 I Research Centre of Central Marine Fisheries Research Institute P.B. No. 244, Hoige Bazar, Mangalore - 575 001, Karnataka, lndia ' Geological Survey of lndia Marine Wing, Pandeshwar, Mangalore - 575 001, lndia *E-mail: dineshbabuap@yahoo.co.in In Indian trawl fisheries, fishes brought for human consumption in  fresh or processed form are termed as commercial landing and the rest brought t o  shore for fishmeal and fertilizers are called low valued bycatch (LVB). LVB is supplementing economical benefit to trawl operators, which is fetching a good amount in fish meal market and in  201 1 the estimated value realised for LVB was about Rs. 72 crores from eight major trawl fishing centres in lndia. This demand is turning out t o  be a threat for marine fish production in  the future, since LVB was found to be constituted by 247 species of fishes and shellfishes and most of them are juveniles of commercial fishes. The study conducted the seasons in  which the juvenile bycatch of the commercial species are high in  percentage. The paper stresses the need for such studies with more specialized objectives and illustrates the uti l i ty of the spatio-temporal data collection in suggesting seasonal and spatial restrictions in  fishing operations in  tropical multispecies scenario.
