Summary The length weight relationships ( LWR s) of ten tropical finfish species from north eastern Arabian Sea, India were studied. Specimens were caught using a wide range of fishing gear mainly trawl nets (20–25 mm), dol nets or bag nets (20–40 mm) and gill nets (80–270 mm) operated in Maharashtra maritime waters during 2012–2016. The specimens were measured for total length, and weight, then dissected and the sex confirmed. Previously unavailable in FishBase, the detailed LWR of Polydactylus mullani is reported for the first time. Maximum total lengths presented for six species in this study are new records. The existence of a differential growth between male and female was confirmed for five species, which was not known earlier. The LWR data will be useful for deriving future sustainable management and conservation strategies.
