采用实验生态学方法研究了不同规格近江牡蛎的呼吸和排泄生理生态学参数.结果显示,近江牡蛎耗氧率RO 随软体干重(W)的增加而减小,体重对近江牡蛎耗氧率(RO)的影响达极显著水平,RO =1.8232W?0.7600,(R2=0.8313, P<0.01);近江牡蛎的排氨率(RN)和排磷率(RP)随软体干重的增加而降低,呈负相关关系;而氧氮比O/N和氮磷比N/P在各组间未达显著水平(P>0.05), RN =0.0930W?0.6582(R2=0.7444, P<0.01)、RP =0.0126W?0.8874(R2=0.9224,P<0.01);各组不同规格近(大小)江牡蛎的O/N值较高,而N/P值则随规格增大而呈上升趋势,但差异也不显著(P>0.05).这些研究结果对牡蛎养殖密度和环境关系分析及牡蛎健康养殖具有重要参考价值.

@@@@The relationship of respiration and excretion to body size in Crassostrea hongkongensis was studied under controlled laboratory conditions, in hopes of providing some scientific data for assessing the carrying capacity of aquaculture, ecological and physiological studies of C. hongkongensis. The results showed that the oxygen consumption rate (RO) decreased significantly over the increase of dry tissue weight (W) among the groups of different body sizes (P<0.01), and the ammonia excretion rate (RN), and phosphorus excretion rate (RP) of C. hongkongensis yielded significant variations among the groups of different sizes in terms of dry tissue weight (P<0.01). However, no significant difference of O/N and N/P ratio among these groups was detected (P>0.05). The oxygen consumption rate, ammonia excretion rate, and phosphorus excretion rate of C. hongkongensis were correlated negatively with the dry tissue weight. The correlations were presented by the equations RO=1.8232W?0.7600 (R2=0.8313, P<0.01); RN = 0.0930W?0.6582 (R2= 0.7444, P<0.01); and RP = 0.0126W?0.8874 (R2= 0.9224, P<0.01). The values of O/N were high in all groups, and the N/P ratios showed incremental trend over the dry tissue weight increasing among the groups.
