褶皱臂尾轮虫;酵母;饵料藻类;最适投喂密度;培养效果
摘  要:
采用种群累积培养法研究了两种酵母、两种藻类对褶皱臂尾轮虫的最适投喂密度。结果表明 ,这四种饵料对褶皱臂尾轮虫的最适投喂密度 (× 10 6cell·ml-1)分别是 :干酵母 ,15 ;鲜酵母 ,5 ;微绿球藻 ,4 5 ;三角褐指藻 ,2 0。同时 ,在最适密度下比较了这四种饵料对轮虫的培养效果。结果表明 ,四种饵料对轮虫的培养效果以微绿球藻为最优 ,其它依次为三角褐指藻 ,鲜酵母 ,干酵母。实验结果显示 ,褶皱臂尾轮虫批量培养及至工厂化培养的首选饵料是微绿球藻和三角褐指藻

摘  要:
Comparative studies on optimum feeding densities of two planktonic algae and two yeasts for the ingestion and growth of the rotifer, Brachionus plicatilis, were conducted by using population accumulative culture method, and regulating food densities once a day. A comparative test of feed efficiency of two alage and two yeasts for rotifer were undertaken on the basis of its experiment of optimunm feeding densities. The results show that optimum feeding densities ( ×10 6 cell·ml -1 ) of the algae were 45 for Nannochloropsis oculata, 20 for Phaeodactylum tricornutum and of the yeast were 5 for fresh yeast, 15 for dry yeast. The feed efficiency of Nannochloropsis oculata for the rotifer was more excellent than other three foods.
