Summary Length–weight relationships of 41 fish species (20 families) collected from the Korangi‐Phitti Creek area on the northern side of the Indus delta at the northern Arabian Sea are presented. This study provides first reports of length–weight relationships for seven species ( Sardinella brachysoma , Arius arius , Trachinotus mookalee , Nuchequula blochii , Gerres limbatus , Brachirus orientalis , and Synaptura commersonnii ). The coefficients of determination ( r 2 ) were > 0.90 for 35 species. Estimates of b ranged from a minimum 2.204 for Liza carinata to a maximum of 3.535 for Pseudorhombus arsius ; 16 species showed isometric growth ( b = 3), eight species showed positive allometric growth ( b > 3), while 17 species showed negative allometric growth ( b < 3).
