Abstract
Abstract Length-weight relationships of various shrimp species were examined based on data from bottom trawl surveys from May 2014 to April 2015 in the East China Sea. A total of 2335 individuals belonging to Penaeidae and Solenoceridae were measured and weighed. Significant length-weight relationships were found for all species. The b-values of the length-weight relationships ranged from 2.0855 (Trachysalambria curvirostris) to 3.4808 (Metapenaeopsis barbata) with a mean value of 3.10 (±0.05). The differences in b-values between sexes and seasons were also examined. Whenever possible, b-values were compared for the species obtained both in this study and some of the species previously reported in other studies. Differences in the b-values for the same species in different areas suggest the influence of differences in environmental or habitat factors, including temperature and depth.
