Abstract

The length-weight relationships (LWRs) were studied for 616 individuals covering 10 families of 12 fish species (i.e., Planiliza subviridis, Opsarius barna, Nandus nandus, Clarias batrachus, Odontamblyopus rubicundus, Taenioides cirratus, Anabas testudineus, Mystus gulio, Mystus tengara, Oreochromis mossambicus, Puntius sophore and Hyporhamphus limbatus) and 3 shellfish species (i.e., Penaeus monodon, Fenneropenaeus indicus, Metapenaeus brevicornis). Total length (cm) and body weight (g) were measured for each individual. The allometric co-efficient, b values of studied species ranged between 2.03 (M. gulio) to 3.27 (O. mossambicus) and were highly significant (P < 0.001) for all species. Our results contribute to updating the online database (FishBase or SeaLifeBase) of respective fish and shellfish species.
