摘要
[目的]通过投喂3种常见的鱼类开口饵料,以筛选多鳞白甲鱼仔鱼适宜的开口饵料,旨在为多鳞白甲鱼的大规模苗种培育和人工配合饵料的开发奠定基础。[方法]采用丰年虫、微粒子配合饲料、蛋黄3种开口饵料投喂多鳞白甲鱼仔鱼30 d,研究多鳞白甲鱼在这3种不同开口饵料投喂下的成活率和生长变化情况。[结果]多鳞白甲鱼仔鱼在开口阶段,投喂丰年虫和微粒饲料能够保证较高的成活率,也能满足仔鱼生长的需要,而投喂蛋黄表现为成活率低、生长速度缓慢。[结论]3种开口饵料中,丰年虫是多鳞白甲鱼仔鱼适宜的开口饵料。
[Objective]The purpose of this experiment was to screen out the suitable initial bait for larva of Onychostoma macrolepis by feeding three kinds of common fish initial bait,so as to lay a foundation for large-scale breeding of scaly white turtle and the development of artificial diet.[Method]O.macrolepis larva were raised with forzened rotifer,microparticle diets and yolk for 30 days to study the effects of three different initial diets on the survial and growth of the larva.[Result]The results showed that the larva fed with forzened rotifer and microparticle diets had significant higher survival rates than yolk fed group in opening stage.The larva fed with yolk had the lowest efficiency on the survival rate and growth rate.[Conclusion]The results indicated that forzened rotifer was the best initial diet for O.macrolepis.
