Comprehensive analysis and application of Chinese Cyprinidae swimming ability

Abstract

该研究利用学术论文数据库筛选出中国鲤科鱼类游泳能力相关论文115篇，并用Origin软件进行了数据统计分析，旨在归纳和分析中国鲤科鱼类游泳能力并建立估算方法，可为正处于规划阶段和可行性研究阶段的过鱼设施流速设计提供依据.结果表明：（1）鱼类游泳速度与鱼体长度具有显著的非线性相关关系，据此建立了一系列幂函数经验公式，可为游泳能力和过鱼设施研究及设计提供依据.（2）依据所得到的经验公式和协方差分析可知，喜流水型鲤科鱼类的游泳能力>广适型>喜静水型.根据该研究得到的经验公式并结合行业规范和文献资料，对正处于规划阶段和可行性研究阶段过鱼设施流速设计的建议如下：西南地区以裂腹鱼成鱼为主要过鱼对象的过鱼设施进鱼口吸引流速范围为0.61~0.76 m/s，通道内最高流速阈值为1.28 m/s；长江中下游以四大家鱼成鱼为主要过鱼对象的进鱼口吸引流速范围为0.76~0.93 m/s，通道内最高流速阈值为1.49 m/s，以四大家鱼幼鱼为主要过鱼对象的进鱼口吸引流速范围为0.42~0.62 m/s，通道内最高流速阈值可为0.82 m/s.;In order to provide an estimation method and basis for the fish swimming ability and for the flow velocity design of fish passing facilities in the planning stage and feasibility stage, by searching the papers related to the swimming ability of Chinese Cyprinidae from the internationally recognized academic paper network database, we selected 115 and then compared them with the critical swimming speed, burst speed and total length as describing indexes by using software Origin 9.0. Results indicated:(1) The relationship between fish swimming speed and fish length is allometric rather than isometric. It is recommended that the power function can be used to fit the correlation between fish swimming speed and total length. (2) Based on the empirical formula and the covariance analysis, swimming ability of rheophilic Cyprinidae > swimming ability of semi-rheophilic Cyprinidae > swimming ability of limnophilic Cyprinidae. According to the Design code for fish passage facilities in hydropower projects in China, Guideline for fishway in water conservancy in China and literature references about fish passage facility design, as well as the empirical formula in this study, the flows for fish passing facilities in the planning and feasibility stages in southwest China and the middle and lower reaches of the Yangtze River were recommended as follows. In the southwest China, the attraction flow velocity range of the fish passing facility entrance with adult Schizothoracinae fishes as the target species is 0.61-0.76 m/s, and the maximum velocity of the passage and pool is 1.28 m/s. In the middle and lower reaches of the Yangtze River, the attraction flow velocity range of the fish passing facility entrance with adult four major Chinese carps as the target species is 0.76-0.93 m/s, and the maximum velocity of the passage and pool is 1.49 m/s. The attraction flow velocity range of the fish passing facility entrance with juvenile four major Chinese carps as the target species is 0.42-0.62 m/s, and the maximum velocity of the passage and pool is 0.82 m/s.
