摘  要:
为了研究温度对葛氏鲈塘鳢摄食和生长的影响,测定4、8、12、16、20、24和28℃条件下葛氏鲈塘鳢的摄食率和特定生长率。结表明,在温度范围内葛氏鲈塘鳢的摄食率和特定生长率的变化范围分别是2.36%~19.72%和-0.962%/d~3.009%/d。温度对葛氏鲈塘鳢的摄食率和特定生长率均有显著影响(P<0.05)。在4~24℃条件下,葛氏鲈塘鳢的摄食率和特定生长率均随温度的升高而增加,24℃条件下达到最大值,温度继续上升至28℃时摄食率和特定生长率均呈下降趋势。这说明葛氏鲈塘鳢的适宜生长温度为20~24℃。

摘  要:
Ingestion rate and specific growth rate of Perccottus glenii at 4,8,12,16,20,24 and 28℃ were measured to study the effect of temperature on ingestion and growth of Perccottus glenii. Results indicated that ingestion rate of Perccottus glenii ranges from 2. 36% to 19. 72%,and specific growth rate ranges from-0. 962 to 3. 009 % ·d at experimental temperature,respectively. Temperature affected significantly ingestion rate and specific growth rate of Perccottus glenii( P < 0. 05). Ingestion rate and specific growth rate of Perccottus glenii increased with temperature increase,and reached the peak at 24 ℃,followed by a decrease when temperature increased to 28 ℃. The results suggested that 20-24 ℃ was the range of optimal temperature for growth of Perccottus glenii.
