Length-weight relationships of commercially important marine fishes and shellfishes of the southern coast of Karnataka, India

By K.P. Abdulrahiman, T. Harishnayak, P.U. Zacharia and K.S. Mohamed


The parameters of the length-weight relationship of the form W = aLb are presented for 51 species of commercially important marine fishes and shellfishes caught along the southern coast of Karnataka, India. Samples from commercial (trawl, purse seines, gill nets) and artisanal gears were taken during August 1999 to May 2001. The ‘b’ value ranged between 1.942 and 3.616 with a mean of 2.80, standard deviation of 0.32, and mode of 3.Length-weight relationships, Marine fish, Shellfish, Stock assessment, India, Karnataka,
