摘要: 研究了2种酵母单独投喂萼花臂尾轮虫的最适密度、饵料效果及与藻类搭配的投喂效果。结果表明,在5种密度下,面包酵母和啤酒酵母的最适密度分别为10和5×106个·ml-1.用面包酵母和啤酒酵母培养轮虫所得到的种群密度和瞬时增长率分别是用蛋白核小球藻培养的40.2%、26.0%和85.5%、76.6%.用面包酵母和蛋白核小球藻适当比例搭配投喂轮虫,其效果接近或超过单一用小球藻在最适密度下的培养效果。

Abstract: Feeding experiments were conducted to search after the optimum density and relative effeciency of two kinds of yeast Saccharomyces cerevisiae and S. carlsbergensis and their mixture with alga (Chlorella pyrenoidosa) as the food of rotifer (Brachionus calyciflorus) .The results showed that the optimum density of S. cerevisiae and S. carlsbergensis was 10×106 and 5×106 cells·ml-1, respectively.The population density and instantaneous growth rate of the rotifer fed with S. cerevisiae and S. carlsbergensis were 40.2 and 26.6%, and 85.5 and 76.6%, respectively of those fed with alga.The feeding effect of yeast-alga mixture in a proper proportion was equal or superior to that of alga.
