近几年来,日本的水产研究单位,很重视鱼虾贝种苗初期饵料(单细胞藻、轮虫及其他微型饵料生物)的稳定高产培养技术开发研究。长崎水试、石川增试、神奈川淡试、熊本水试(大矢野分场)及广岛水试等单位,还联合进行初期饵料培养技术的统一课题与自选课题研究并获得成效。现据吉田范秋先生惠赠的资料,摘要介绍长崎县水试场4年来在这方面的研究结果及尚待探讨的问题。一、海产小球藻的培养 1.海产小球藻培养方法的探讨海产小球藻在水温26—29.5℃条件下,分别以硫酸铵、尿素、过磷酸钙和“Clewat—32”等4
In recent years, Japan’s aquatic research unit attaches great importance to the development of stable and high-yield culture technologies for the initial feeding of fish and shellfish seedlings (unicellular algae, rotifer and other micro-food organisms). Nagasaki water test, Ishikawa test, Kanagawa test, Kumamoto water test (Yokohama branch) and Hiroshima water test and other units, but also jointly conducted preliminary research on the uniform and self-selected topics of the initial bait culture technology and achieved results. According to the information provided by Mr. Yoshida Fan Qiu, the paper summarizes the research results and the issues to be discussed in this aspect of Nagasaki water test facility for four years. First, the cultivation of marine chlorella 1. Discussion on the cultivation of marine chlorella Chlorella in the water temperature 26-29.5 ℃ conditions, respectively, ammonium sulfate, urea, superphosphate and “Clewat-32” and other 4
