| 摘 要： | 目的]为两种“吉富”罗非鱼的养殖结构优化及其运输提供理论依据。方法]在恒温20±0．5℃条件下，用呼吸室法对“JNM”和“GTC”两种吉富罗非鱼的呼吸耗氧率、窒息点进行了试验。结果]①平均体重为381．90±19．25g的“JNM”昼夜平均耗氧率为O．069±0．022mg/（g·h）；平均体重为302．00±7．76g的“GTC”昼夜平均耗氧率为0．033±0．017mg/（g·h）。②两种试验鱼的耗氧率与饥饿时间呈负相关，代谢率随着饥饿程度的加深而降低。③“JNM”和“GTC”的窒息点分别是：1．54±0．17、1．70±0．23mg/L。结论]当温度在20±0．5℃时，“GTC”与“TNM”相比，需氧量大．窒息点低。

| Abstract: | Objective]The research aimed to provide the theoretical basis for the aquaculture structure optimization and transportation of two kind of GIFI strain Nile Tilapia.Method] Under constant temperature 20±0.5 ℃,the oxygen consumption rate and asphyxiation point of Oreochromis JNM and Oreochromis GTC were studied by using the method of respiratory chamber.Result] ① The oxygen consumption rate were 0.069±0.022 mg/(g·h) for O.JNM(average weight 381.90±19.25 g) and were 0.033±0.017 mg/(g·h) for O.GTC(average weight 302.00±7.76 g).② The oxygen consumption rate of Oreochromis niloticus changed inversely with the starvation of fish.The metabolic rate decreased when the starvation deeped.③The asphyxiation points were 1.54±0.17 mg/L for O. JNM,were 1.70±0.23 mg/L for O.GTC.Conclusion] When the temperature at 20±0.5 ℃,O.JNM cost more oxygen than O.GTC,the asphyxiation points of O.JNM was lower than O.GTC. |
