摘要
本文测定了不同温度(20、24、28、32℃)下黄颡鱼仔、稚、幼鱼的耗氧率和氨氮排泄率。结果表明,黄颡鱼的耗氧率、氨氮排泄率随体质量增大而降低,随温度升高而增大;体质量、温度与耗氧率和氨氮排泄率的关系可用RO=0.0224T0.6428積0.1284W、RN=0.2654T0.4326積0.1417W表示。
Oxygen consumption rate (RO) and NH3-N excretion rate (RN) of larvae, juvenile and young Pelteobogrus fulvidraco were studied at four different temperatures (20, 24, 28, 32℃). The results show that both RO and RN of Pelteobogrus fulvidraco rise with temperature increasing and reduce along with weight increasing; The relationships among weight, temperature, RO and RN can be expressed by the following equations: RO = 0.0224T0.6428積0.1284W , RN=0.2654 T0.4326積0.1417W.
