TR鲍参人工鱼礁的鲍参增养殖试验

[目的]研究利用TR人工鱼礁养殖刺参可能获得的经济效益。[方法]于2016年10月从山东烟台采购一批体长为6~9 cm,平均体重为42.5 g的刺参幼苗,在温州石坪海洋牧场基地进行养殖试验,采用在一定范围内放养的方式进行饲养,历时101 d。[结果]试验组1和试验组2的平均体长分别为10.33和9.87 cm,平均体重分别为68.5和63.5 g,成活率分别为95.2%和92.9%,因此初步认定利用TR鲍参人工鱼礁剩余空间对刺参养殖产生经济效益的方案是可行的。该次养殖试验过程中,将羊栖菜、石莼2种藻类栽培在TR人工鱼礁场周围敷设的延绳浮筏上,模拟自然藻类生长环境,滋生海洋微生物,聚集海洋生物,从而达到为刺参提供天然饵料的目的,不但有效地减少了潜水员的工作量,降低了刺参养殖的投入成本,也使得刺参食用天然饵料,实现自然状态下的生长,避免了营养过剩引发的病害问题等。[结论]该研究可为TR鲍参人工鱼礁养殖刺身提供参考。

Shark's Aquaculture Experiment of TR Shark's Artificial Reef

[Objective] This article aims to explore the possible economic benefits of sea cucumber culture by using TR artificial reefs.[Method] The sea cucumber seedlings were from Yantai,Shandong.Body length was 6-9 cm and their weight was 42.5 g in average.Feeding experiment was carried out by stocking sea cucumber with limits for 101 days in Shiping Marine Ranching in Wenzhou.[Result] Average body length of the test group 1 and the test group 2 were 10.33 cm and 9.87 cm respectively,with average body weight of 68.5 and 63.5 g,the survival rates were 95.2％ and 92.9％,respectively.Therefore,it was feasible to use the residual space of TR artificial reef to obtain economic benefits by culturing Apostichopusjaponicus.During the culturing process,Sargassumfusiforme and Ulva were cultivated on the long line and floating rafts to form a natural marine environment.It bred marine microorganism and congregated marine creatures,thus achieved baits to supply for sea cucumbers.Besides,it not only reduced workload of divers and cut the cost,but achieved natural growth of sea cucumber by providing natural baits which prevented problems brought by overnutrition.[Conclusion] The research can give reference for culturing shark.
