用室内实验生态学方法研究不同规格和温度对方斑东风螺(Babyloniaareolata)耗氧率(O)和排氨率(N)的影响。实验所用方斑东风螺规格为壳高(3 147±0 115)～(6 862±0 237)cm,软体部分干重(2 0145±0 12)～(11 0636±0 36)g。结果表明:(1)个体大小、温度以及二者的综合效应均对其耗氧率和排氨率有极显著的影响(P<0 01)。在实验温度范围内(13～33℃),不同规格的方斑东风螺耗氧率的总平均值为1 413mg/(h·g),排氨率的总平均值为217 05μg/(h·g)。(2)在实验条件下,方斑东风螺的软体部分干重(W)与耗氧量(R)之间的回归关系符合幂函数方程R=aWb,其中a的取值范围为0 9984～3 0128,平均值是1 7894;b值的范围为0 7692～0 8985,平均值为0 8430。在13～28℃温度范围内,不同规格的方斑东风螺的耗氧率随着温度的升高而增加,当温度升高到33℃时,耗氧率反而下降。(3)实验温度下,W与排氨量(A)也可用幂函数方程A=cWd表示,c值的范围为277 4091～405 3933,平均值为326 6857;d值的范围是0 4519～0 8864,平均值是0 6683。随着温度的升高方斑东风螺的排氨率呈上升趋势。(4)实验证实,高温将进一步提高方斑东风螺蛋白质的代谢水平,耗氧率和排氨率与温度(T)、W的二元线性回归方程分别为:O=-0 521-0 038W+0 050T、N=-152 640-10 581W
Effects of different specifications and temperature on Oxygen Consumption (O) and Ammonia Excretion Rate (N) of Babylonia areolata were studied by indoor experimental ecology. The test was conducted with the shell height (3 147 ± 0 115) ~ (6 862 ± 0 237) cm and the soft part dry weight (2 0145 ± 0 12) ~ (11 0636 ± 0 36) g. The results showed that: (1) The individual size, temperature and the combined effects of both had a very significant effect on the oxygen consumption rate and ammonia excretion rate (P <0.01). In the range of experimental temperature (13 ~ 33 ℃), the average oxygen consumption rate of Phyllanthus urinosa with different specifications was 1 413 mg / (h · g), and the average value of ammonia excretion rate was 217 05 μg / (h · g). (2) Under the experimental conditions, the regression relationship between the dry weight (W) and the oxygen consumption (R) of the mollusks of R. solani is in accordance with the power function equation R = aWb, where a is in the range of 0 9984 ~ 3 0128 with an average value of 1 7894; b values ranged from 0 7692 to 0 8985 with an average of 8430. In the temperature range of 13 ~ 28 ℃, the oxygen consumption rate of Elaeagnus molluscum with different specifications increased with the increase of temperature, while the oxygen consumption rate decreased when the temperature was raised to 33 ℃. (3) Under the experimental temperature, W and ammonia displacement (A) can also be expressed by the power function equation A = cWd, the range of c is 277 4091 ~ 405 3933 and the average is 326 6857. The range of d is 0 4519 ~ 0 8864, the average is 0 6683. With the increase of temperature, the rate of ammonia excretion of M. orientalis showed an upward trend. (4) Experiments confirmed that the high temperature will further improve the protein level of Asteraceae protein metabolism, oxygen consumption rate and ammonia excretion rate and temperature (T), W binary linear regression equation were: O = -0 521-0 038W +0 050T, N = -152 640-10 581W
