本文报道了四种兔鱼，连结蓝子鱼（Siganus concatenata）、蓝子鱼（S. oramin，S. striolataandS.弗吉尼亚被关押在饲养池和喂养底栖藻类。在提供的101种藻类和4种维管植物中，鱼只吃67种。测定了23种藻类的选择性指数E_1。其中，浒苔属（Enteromorpha）、江蓠属（Gracilaria confervoides）和江蓠属（G.结果表明，圆柱形的指数最高，分别为E = 0.594、E = 0.269和E = 0.182。
Four species of rabbitfishes,Siganus concatenata, S. oramin, S. striolataandS. virgatawere held in rearing tanks and fed with benthic algae. Out of 101 algae species and 4 vascular plants offered, the fishes ate only 67 species. The electivity indices E, for 23 algae were determined. The speciesEnteromorpha intestinalis, Gracilaria confervoidesandG. cylindricaproved to have the highest indices with E = 0.594, E = 0.269 and E = 0.182, respectively.
