火腿许水蚤培养条件的初步研究

Preliminary study on cultural conditions of Schmackeria poplesia

本文研究了不同种饵料单独喂养和混合喂养，同种饵料不同浓度以及温度和盐度等环境因子对火腿许水蚤（Schmackeriapoplesia）培养效果的影响。经6～7d培养，初步得出：在单种饵料中，等边金藻（Isochrysissp．）效果最好，三角褐指藻（Phaeodactylumtricornutum）次之，小球藻（Chlorellasp．）较差。混合饵料投喂较单种饵料效果好，单独喂养小球藻，其浓度应在≥60×104个／cm3较适宜；当温度接近自然海区水温时，有较高的增殖率；火腿许水蚤在盐度21时，群体增殖率最高。在盐度14时，经19d培养，存活率最高。木文还就铒料、温度和盐度对火腿许水蚤培养效果进行讨论。

the reproduction of Schmackeria poplesia population has been investigated under the cultivation of Chlorella sp. of different concentrations, the cultivation of different unicellular algaes respectively and in mixture as well as environment conditions of temperature and sallnity. Preliminary concluslons were drawn after 6d period, Among the three specles of unlcellular algaes,the effect of Isochrysis sp. is the best,while Phaeodactylum tricornutum the second and Chlorella sp. the lowest. Generally, the effects of mixeure feeding are significant than those of single-species feeding. The optimum concentration of Chlorella sp. for Schmackerla poplesia was 60×104 ind. /cm3 and above one. The reproduction rate of Schmackeria popesia population was higher when temperature of cultivation was close to sea water and salinity was 21. Corresponding discussions are followed and study on commodity food for copepods is suggested.
