Abstract: The oxygen consumption and ammonia excretion rates were determined in variously colored abalone Haliotisdiversicolorsupertexta with shell length of (40.58±1.69)mm (group S), (47.90±0.74)mm (group M), and (50.74±0.85)mm (group L) held in a 3 L jars at a density of 0 (control group), 1(group L), 2(group M), and 3 (group S) at water temperature of 13, 18, 23, 28 and 33 ℃ in a laboratory by ecological methods to evaluate effects of temperature and body weight on oxygen consumption and ammonia excretion rates of variously colored abalone. It was found that the oxygen consumption (Y) and ammonia excretion (A) rates were negatively correlated with body weight in variously colored abalone under the experiment temperature of 13-33 ℃ and salinity 27, with power function of Y=aW-b, where, a, 0.272 7-0.857 9; b, 0.555-0.921, and A=aW-b, Where, a, 0.415 1-1.184 3; b, 0.462-0.847. The water temperature, body size and their interaction were shown to have significant effects on the oxygen consumption rate and ammonia excretion rate(P<0.05). The oxygen consumption rate was increased with warming temperature within 13-28 ℃, with the maximal oxygen consumption rate at 28 ℃ in the three sizes of variously colored abalone, and at over 28 ℃ declining in oxygen consumption rate. There was constant increase in oxygen consumption rate within the experimental temperature, with the oxygen consumption rate Q10 ranging from 0.202 to 2.839, the average value of 1.365, and ammonia excretion rate Q10 varying from 1.278 to 3.093, with the average value of 1.813. The variously colored abalone with different szes had O/N values of 0.294-0.795, with an average value of 0.593. The findings provided basic date and references for energy budget research and culture of variously colored abalone.
