Length-weight Relationships of Three Fish Species from Yellow Sea along Coastal Waters of Shandong Province, China

In this study, length-weight relationships (LWR) of three fish species (Lepidotrigla microptera, Liparis tanakae and Trachidermus fasciatus) from the Yellow Sea along coastal waters of Shandong province, China were estimated. Ninety-one samples were collected from March to June 2019 through trawl nets in the Yellow sea area (36 degrees 27'02 '' N 121 degrees 08'68 '' E). The length-weight relationships of Lepidotrigla microptera, Liparis tanakae and Trachidermus fasciatus can be expressed as W-L.microptera = 0.0123L(2)(.9)(2), W-L.(Tanakae )= 0.0848L(3)(.4)(6), W-T.fasciatus = 0.067L(3.)(06), respectively. The values of exponent b ranged from 2.92 to 3.46 for these three species. Results from the present study indicate that the weight increase of Liparis tanakae and Trachidermus fasciatus was positive allometric during the survey period. This study provided basic information for fisheries management in Yellow Sea along coastal waters of Shandong province.
