摘　　要：选择福建省黄岐半岛的皱纹盘鲍、南日岛的杂交鲍和古雷半岛的杂交皱纹盘鲍为研究对象,通过分析三个地点的鲍鱼和其可能的食物来源的稳定性碳和氮同位素比率,利用贝叶斯混合模型分别得出三个地点鲍鱼的食性.研究发现,三地鲍鱼的食性存在差异,黄岐半岛、南日岛和古雷半岛的鲍鱼的食物来源分别有3,5和4种,通过比较鲍鱼的食性比例与投饵比例之间的差异,提出应减小龙须菜占比,增大海带占比的建议.We choose 3 different kinds of abalones which are collected from Huangqi Peninsula,Nanri Island and Gulei Peninsula in Fujian Province,and analyse the stable carbon and nitrogen isotope ratios of them and their food resources.Then we use Bayesian mixture model to get the abalone, s feeding hab-its. We find that the feeding habits of the 3 kinds of abalones are all different from each other. Their food sources are 3,5 and 4, respectively. We put forward a proposal that we should decrease the asparagus and increase the kelp in abalone farming.
