| 摘 要： | 用封闭静水式装置测定了体重2.3-4.7g厚颌鲂幼鱼的耗氧率和窒息点,用封闭静水式和封闭流水式装置测定了体重9.9-55.1g圆口铜鱼的耗氧率和窒息点。结果表明:在15-27℃条件下,厚颌鲂的耗氧率随着温度的升高而升高,耗氧率与水温呈线性关系;在水温24.8℃时厚颌鲂的窒息点为(0.91±0.08)mg/L。在水温23-27℃、封闭静水实验条件下,圆口铜鱼的耗氧率随体重增加而降低,两者呈指数关系;圆口铜鱼耗氧率昼夜变化明显,夜间耗氧率大于白天,推测圆口铜鱼夜间活动较多。在水温24.5-26.0℃条件下,体重21.8-46.3g圆口铜鱼的窒息点变幅较小,平均(1.14±0.23)mg/L。研究表明两种鱼都为耗氧率和窒息点较高的鱼类。

| Abstract: | Both of Megalobrama pellegrini and Coreius guichcnoti are endemic fish in the upper reach of Yangtze River(from Yichang to Yibin).The construction of the hydroelectric projects,such as the Gezhouba Dam,the Three Gorges Dam,and hydropower cascade exploitation in the Jinsha River,drastically modifies physical environment and regulates flow in the Yangtze River course.This causes the habitats fragmentation to fish,blocks their migration routes,and destroys their spawning grounds,leading to the severe negative ... |
