Abstract

The length-weight relationship (LWR) of eight commercially important marine fish species belonging to 5 families landed by trawlers along the Mumbai coast of India from October 2015 to May 2016 is reported. Fish samples were collected from trawl catch of M.F.V NARMADA, training cum research vessel of ICAR-CIFE. The species studied were Coilia dussumieri, Cynoglossus arel, Harpadon nehereus, Lepturacanthus savala, Johnius borneensis, Johnius macrorhynus, Johnius belangerii and Johnius glaucus. The regression coefficient ‘b’ values were estimated as 2.781, 2.869, 3.345, 3.312, 3.132, 3.099, 3.152, and 3.059 respectively. The analysis include the first record of L-W relation of J. glaucus, not available in FishBase.
