小丑鱼室内循环水养殖设施与技术

摘要

为了实现规模化人工养殖小丑鱼（ Amphiprioninae），研发了小丑鱼室内循环水养殖设施和技术。1组循环水养殖系统由10个玻璃钢养殖桶和1个水处理玻璃缸及管道系统组成，采用物理过滤、生化过滤、藻板过滤进行循环水处理。1组循环水养殖系统每3个月可养殖产出全长约3．5 cm的商品小丑鱼5000尾，养殖存活率达80％以上。从2014年至2015年，利用该设施养殖生产出商品小丑鱼10余万尾。和常规的食用海水鱼循环水养殖设施相比，小丑鱼室内循环水养殖系统主要减少了蛋白分离器、气浮机、微滤机等设备，增加了藻板过滤设施。研究表明，小丑鱼室内循环水养殖系统建造成本低、运行能耗低、管理维护简单、水质稳定，可基本实现全封闭循环水养殖，适合进行小丑鱼等海水珊瑚礁观赏鱼类的规模化养殖生产。%In order to produce marketable clownfish in large scale, facilities and techniques for indoor recirculating aquaculture of sea-water clownfish were developed.One group clownfish recirculating aquaculture system was composed of 10 round fiberglass tanks, 1 fibre glass tank for waster water purification and piping system.Physical filtering, biochemical filtering, and plastic algal plate filtering were adopted for circulating watzer purification.One group system could produce 5,000 marketable clownfish with size of 3.5 cm in total length in 3 months, and the survival rate was above 80%.More than 100,000 marketable clownfish have been produced from 2014 to 2015 in these systems. Compared with the conventional seawater edible fish recirculating aquaculture system, the indoor recirculating aquaculture system of clownfish reduced the protein separator or air flotation equipment and microfiltration machine, and supplement the plastic algal plate filtering system.The research showed that the indoor recirculating aquaculture system of clownfish was characterized by low construction cost, low operation energy consumption, easymanagement and maintenance, and stable water quality, which could basically achieve the goal of closed recirculating aquaculture, and was suitable for large-scale aquaculture production for clown fish and other sea coral reef ornamental fish.
