摘　　要：研究了不同浓度的三角褐指藻和不同种单胞藻单独喂养及混合喂养对婆罗异剑水蚤Ａｐｏｃｙｃｌｏｐｓ ｂｒｏｎｅｏｅｎｓｉｓ群体增殖的影响。经１０ｄ的培养，初步得出：三角褐指藻对婆罗异剑水蚤适宜的浓度为２０×１０＾４￣５０×１０＾４ｃｅｌｌ／ｍｌ；在４种单胞藻中，等鞭金藻效果最好，扁藻次之，小球藻最差；几种单胞藻混合喂养婆罗异剑水蚤，其群体增殖效果总体上比单种藻类喂养来得显著。The reproduction of Apocyclops borneoensis population has been investigated by feeding Phaeodactylum tricornutum of different concentrations, and different unicellular in mixture. Preliminary conclusions were drawn after a 10 d period. The optimum concentration of P. tricornutum for A. borneoensis lies between 20 ×10~4 cell/ml and 50 × 104 cell/ml. A- mong the four species of unicellular algaes, the effect of Isochrysis sp. is best, while Platymonas helgolandica the second, and Chlorella sp. the worst. Generally, the effects of mixture feeding are significant than those of single-species feeding. Corresponding discussions are followed.
