Effects of temperature on food consumption, growth and oxygen consumption of freshwater prawn Macrobrachium rosenbergii (de Man 1879) postlarvae

摘要: Effects of temperature on food consumption, growth and oxygen consumption were estimated for the freshwater prawn Macrobrachium rosenbergii postlarvae at 23 °C, 28 °C 33 °C in laboratory. The results showed that animal's initial body weight had a close linear relationship with growth. Food increased directly temperature. Consumption rates (C; mg day−1 ind−1 ) groups much higher than 23 °C group (P < 0.001), group's rate was (P < 0.05). (W; mg) could be described as: C = 0.0679W + 0.185t− 3.17. Growth significantly among specific rate, as follows: SGR = −0.110W + 0.213t + 0.176. However, no effect efficiency. Oxygen (P < 0.01). weight-specific (mg O2 g−1 h−1) 0.83, 1.16 1.49 mg O2 g−1 h−1 61.92 mg M. rosenbergii.
