摘要： This study estimated the length-weight relationships (LWRs) and length-length relationships (LLRs) for 6 fish species in the middle Yangtze River basin and its adjacent lakes (Ochetobius elongatus (Kner 1867), Rhinogobio cylindricus (G & uuml;nther 1888), Hemibagrus macropterus (Bleeker 1870), Pseudobagrus albomarginatus (Rendahl 1928), Siniperca knerii (Garman 1912), and Coreosiniperca roulei (Wu 1930)). All fish specimens were seasonally collected through scientific research monitoring of fishery resources from May 2020 to June 2023. A triple gillnet (with a mesh size of 20-30 mm, a height of 2.0-4.0 m, and a length of 30-50 m) was employed for the capture. The LWRs and LLRs of all specimens were highly significant (p < 0.05), featuring high correlation coefficients (r(2) >= 0.9511). These findings not only enriched the data in FishBase but also offered supplementary references for the management of the Yangtze River during its fishing ban period.
