摘要
用水瓶法和径流装置测定了锯缘青蟹各期状幼体(Z1～Z5)在不同温度(22、24、26、28、30和32℃)下的耗氧率和氨氮排泄率.实验结果表明,耗氧率和氨氮排泄率随温度的升高而升高,但各期幼体之间存在差异;Q10值表明,最适温度Z1和Z2是24～26℃,Z3和Z4是28～30℃,而Z5是26～28℃;耗氧率和氨氮排泄率与幼体干质量呈幂函数关系,M=aDWb,耗氧率和氨氮排泄率的a值范围分别是119.26～304.64和508.13～942.17,平均值分别为180.23和754.74;b值范围分别是-0.6724～-0.5155和-0.7729～-0.4536,平均值分别为-0.5865和-0 6131;不同温度下各期幼体的O/N平均值为15.6,青蟹幼体主要以蛋白质代谢物质;耗氧率和氨氮排泄率与温度和体重的二元回归方程分别为R=14.83+0.526T-0.090DW(r2=0.8211,n=26)和E=6.09+4.47T-0 376DW(r2=0.7796,n=26),F检验表明相关性极显著(F<F0.01).
Oxygen consumption and ammonia excretion of zoea(Z1～Z5) of Scylla serrata were examined by using bottle water method and flowthrough system at six temperature(22,24,26,28,30 and 32 ℃). Results show that oxygen consumption and ammonia excretion increased with temperature rising, but there is difference among each stage larvae. Q10 values indicated that, the optimal temperature of Z1 and Z2 is 24～26 ℃, Z3 and Z4 is 28～30 ℃, and Z5 is 26～28 ℃. The relationship between oxygen consumption or ammonia excretion can be represented all by power equation, M = aDWb, a values of oxygen consumption and ammonia excretion range is 119.26～304.64 and 508.13～942.17 respectively; mean a values is 18023 and 754.74 respectively. b values is -0.6724～-0.5155 and-0.7729～-0.4536 respectively; and mean values is -0.5865 and -0.6131 respectively. The mean values of O/N of all stage larvae at different temperature is 15.6, it indicated that protein is main substrate catabolized by S. settata larvae. The linear regression relationships of oxygen consumption with temperature and larval dry weight is, R=14.83+0526T-0.090DW (r2=0.821 1, n=26) ; and that of ammonia excretion is, U=6.09+4.47T-0376DW (r2=0.779 6, n=26).
