摘要

本文研究了世界上最大的南水北调中线工程中bleekeri、H. leucisculus、Opsariichthys bidens (Xenocyprididae)、Carassius auratus、Cyprinus carpio (Cyprinidae)、Pseudorasbora parva (Gobionidae)、Acanthorhodeus chankaensis和Rhodeus ocellatus (Acheilognathidae) 8种鱼类的长度-重量关系(LWRs)。2015 - 2020年，采用底栖网、刺网、多网刺网和电渔具进行季节性取样。测定系数(r2)在0.964 ~ 0.986之间，b值在2.5 ~ 3.5之间。此外，我们的研究还更新了4个物种(H. bleekeri、H. leucisculus、A. chankaensis和O. bidens)的最大总长度信息。

Length-Weight Relationships of Eight Fish Species in the World’s Largest Water Diversion Project

The study provides the length-weight relationships (LWRs) for eight fish species, viz. Hemiculter bleekeri, H. leucisculus, Opsariichthys bidens (Xenocyprididae), Carassius auratus, Cyprinus carpio (Cyprinidae), Pseudorasbora parva (Gobionidae), Acanthorhodeus chankaensis, and Rhodeus ocellatus (Acheilognathidae), in the world’s largest water diversion project, namely, the middle route of South-to-North Water Diversion Project (SNWDP). Fish specimens were sampled by benthic fyke-nets, gillnets, multimesh gillnets, and electrofishing equipment seasonally from 2015 to 2020. The coefficient of determination (r2) was ranging from 0.964 (R. ocellatus) to 0.986 (H. leucisculus), and the b values for the eight species were within range of 2.5–3.5. Also, our study updates the information on the maximum total length for four species (H. bleekeri, H. leucisculus, A. chankaensis, and O. bidens).
