大银鱼混合营养期的人工投饵实验

报道了大银鱼混合营养期投喂小球藻，金藻，裸藻以及微粒仿生饲料的实验结果，其效果依次为金藻〉微粒仿生饲料〉小球藻〉裸藻。并观察了混合营养期仔鱼的形态变化，为大水面移植和小水体养殖大银鱼提供了理论依据。

Artificial Culture Experiments on Period in Mixed Nutrition of Protosalanx hyalocranius

In the experiment,the fry of the salangid fish Protosalanx hyalocranius at the mixtrophic stage was fed on chlorelia, chrysophyta, euglenophyta and the micro-granular mimicbiological feed respectively. The feeding time and the effect was studied. The result showed that the best feed for the salangid fish was chrysophyta, the next was the microgranular feed,the last two were chlorella and euglenophyta.The morphological change of the fry was also described, which can be helpful to the transplanting and small-sized-water culturing of the fish.
