Abstract

Length-weight relationships (LWRs) were presented for 15 fish species which caught in the East China Sea during 2009–2014. All of the samples were caught by commercial and scientific survey bottom trawl vessels. The commercial fishery survey used one-single bottom trawl with the smallest mesh size 25 cm and light seine fishing with the smallest mesh size 38 cm, however, the scientific survey only used one-single bottom trawl with the smallest mesh size 20 cm. The length and weight of all the fish were measured to the nearest millimeter and milligram, respectively. The application of these estimated values should be limited to the studied waters and observed length ranges. The development and adoption of a standardized sampling format for all studies aiming to determine LWRs should be undertaken.
