室内培养底栖端足类日本大螯蜚饵料研究

Study on marine amphipod Grandidierella japonica cultured in Lab as food

本文在实验条件下探讨了５种饵料对海洋底栖端足类日本大螯蜚的培养效果。实验指标为存活率、生长速度、日增长率和发育状况。结果表明，青岛大扁藻与新月菱形藻１∶１混合液的培养效果最佳，合成饲料是较好的补充饵料，螺旋藻粉不宜作为日本大螯蜚的培养饵料。动物性饵料培养效果不如植物性饵料，但对日本大螯蜚的早期快速成长具有一定的促进作用。

In the five kinds of marine amphipod Grandidierella japonica as food,the strains mixed with platymonos helgolandica and Nitzschia closterium at 1∶1 had the best cultural effects for the survivor、growth and develop of the amphipods juvenile under the experimental conditions.For the species,synthetic food for the river crab should be listed as a potential supplementary food and spirulina cold be not suitable as a goog food.Animal food were not as good as unicellullar algae,but giving a promoting effect to the growth of G. japonica in the early stage.
