摘要
针对海带夏苗致病与育苗水系中细菌大量繁殖有密切的关系,于1984年在福建三沙海带育苗室同时从微生物、生理生态和培养技术三个方面对水系中微生物进行监控,具体步骤为:1.小心地抽出,古海况及气象条件不佳时,即停止抽水;2.育苗海水要经黑暗沉淀和过滤;3.种海带必须健康清洁,将首批放散的孢子水排掉不用,而以第二批孢子水采苗;4.育苗苗帘须经过严格漂洗和消毒。通过以上措施取得育苗的成功。
The Chinese Laminaria summer sporeling cultivation industry has often encountered disease problems during recent years. One of the possible cause was thought to be the overgrowth of certain bacteria in cultivation seawater system. In 1984, bacterial monitoring and controlling for the seawater system was effected by the authors at Sansha Laminaria Sporeling Cultivation Station, Fujian. At the same time some other physio-ecological and cultivation measures has also been taken to promote healthy growth and development of juvenile Laminaria and to prevent diseases. The result was positive. The following measures have to be taken to reduce the abundant growth of bacteria in seawater system: 1) The pumping of seawater should be conducted carfully and stopped when the oceanographic and weather conditions are not good. 2) Pre-treat seawater by sedimentation in darkness and sand filteration to reduce the abundant growth of bacteria effectively. 3) Mother plant of Laminaria for spore collecting should be clean and healthy, and the first batch of zoospores discarded before formal spore collecting. 4) Cultivation strings should be washed and sterilized thoroughly. There is no need for alarming at the appearance of gel like hat at the top of some premature gametophytes, which is not a sign of disease.
