| 摘 要： | 于1997年和1998年8－11月，对大连市大李家湾低排筏、高排筏、凌水桥和棋盘磨4个不同环境条件下筏式养殖海湾扇贝的呼吸率、饵料和环境因子进行了现场研究。结果表明，海湾扇贝呼吸率在8月最高，9月次之，10月基本最低，11月略有升高的趋势；大李家湾低排筏群体呼吸率最高，高排筏次之，棋盘磨较低，凌水桥最低。海湾扇贝耗氧量与其体重呈正相关；呼吸率与遗传多态位点杂合度（MLH）呈负相关；与饵料质量有明显的相关性，与环境因子有一定的相关性。

| Abstract: | The bay scallops ( Argopecten irradians irradians ) respiratory rate, diet quantity and quality, environmental conditions and multilocus heterozygosity (MLH) were determined in specimens from 4 cultivation rafts in the coast in Dalian (China). Choice of raft location in different cultivation sea was intended to provide an oceanic terrestrial gradient of ecological conditions. The investigated rafts were respectively the near coastal one in Dalijia Bay, the far coastal one in Dalijia Bay, the near coastal ones in Lingshuiqiao and Qipanmo, and the time is on Aug.27, Sept.18, Oct.8, Nov.1, 1997 and Aug.25, Sept.15, Oct.8, Nov.3, 1998 Experiments were performed under natural conditions of food availability and temperature in laboratory to account for the variability in nutrient concentration and environmental conditions associated with the respiratory metabolism of the hanging culture.The results indicated that bay scallop's respiratory rate was highest on August, low on September, lowest on October, little higher than the last month on December; and the rate was the highest in the near coastal raft in Dalijia Bay, the low in the far coastal raft in Dalijia Bay and Qipanmo, the lowest in Lingshuiqiao. The oxygen consumptions were positive relative to their weights, and the respiratory rates were negative to the population multilocus heterozygosity (MLH), relative to diet quantity and quality, relative to environmental factors.The tested bay scallops were introduced to China from USA, and there were no the remarkable genetic difference in these populations. But the respiratory and genetic differences among the populations were obvious due to the difference in the reared ecosystem. The say scallop's respiratory metabolism level mainly depended on the food and environmental conditions, and in Lingshuiqiao is the lowest among the four populations because of the food and environmental conditions being the best. |
