Summary This study presents the first report of length–weight relationships ( LWR s) for Apocryptes bato (Hamilton, 1822), Salmophasia phulo (Hamilton, 1822), and Silonia silondia (Hamilton, 1822), excluding Anodontostoma chacunda (Hamilton, 1822) , from fishermen's catches landed in a coastal artisanal fishery at Patuakhali, Southern Bangladesh. Specimens were sampled occasionally over a period of 1 year between August 2014 and September 2015. Fishes were collected from coastal fishermen using cast nets (mesh size <0.5 cm) for A. bato, set bag nets (mesh size 0.5 cm) for A. chacunda and S. silondia, and lift nets (mesh size <0.5 cm) for S. phulo . The LWR s obtained were W = 0.006L 2.99 , ( r 2 ) = 0.976, W = 0.011L 3.04 , ( r 2 ) = 0.971, W = 0.006L 3.00 , ( r 2 ) = 0.945 and W = 0.007L 2.99 , ( r 2 ) = 0.988 for A. bato, A. chacunda, S. phulo, and S. silondia , respectively.
