Length-weight relationships for seven fish species from the Nandujiang River in Hainan Island, China.

Length-weight relationships ( LWRs) were determined for seven fish species collected during 2014 and 2015 between January and July each year from Nandujiang River. The study used drift gillnet with 4 cm mesh (100 m long × 1.2 m high) as well as electrofishing. The parameter ' b' of the LWR equations varied between 2.963 to 3.171 for the species studied.
