Length-weight relationships of three fish species from Dayang River, northeast China

Length-weight relationships (LWRs) were determined for three fish species from Dayang River, northeast China. The specimens were collected using drift gillnets (80 x 2 m, four mesh sizes: 4, 5, 6 and 8 cm) seasonally from April to November 2020. All LWRs were statistically significant (p < .01), with r(2) values being >= 0.95. This study provides a new record of LWR for Takifugu xanthopterus and the new size ranges for Planiliza haematocheila (15.6-66.2 cm) and Lateolabrax japonicus (29.9-45.4 cm).
