| 摘 要： | 通过构建石斑鱼的循环水养殖系统及水源热泵加温系统,达到在北方大规模养殖石斑鱼的目的。养殖系统由养殖池、弧型筛、循环泵、蛋白分离器、浸没式生物滤池、脱气池、溶氧池、紫外线灭菌器、液氧站组成。采用养殖废水收集及过滤装置处理后的养殖废水作为水源热泵的水源,通过2个冬季的运行,其冬季制热的平均制热能效比(COP)为2.66。在系统中养殖的第1批青斑鱼11个月内由24.41 g生长到480.66 g,存活率超过97%。养殖的第2批青斑12个月内由23.36 g生长到400.46 g,存活率达到84.5%。养殖的珍珠龙胆石斑7个月内由48.46 g生长到511.36 g,存活率达到71.24%。养殖的东星斑12个月内由41.13 g生长到223.56 g,存活率达到65.52%。本系统可实现青斑、珍珠龙胆石斑、东星斑等品种的常年均衡生长,并可降低石斑鱼的养殖成本。

| Abstract: | This paper aims to culture the grouper on a large scale in the North by constructing recirculating aquaculture system RAS and water source heat pump system for the grouper.The aquaculture system consists of fish tank, curve screen filter, pump, protein skimmer, bio-filter, degassing tank, oxygenation tank, UV light and liquid oxygen station.Aquaculture wastewater treated by the collection and filtration system is used as the source of water source heat pump, and after 2 winters of operation, the average coefficient of performance (COP) of heating in winter is 2.66.In the system, the first batch of Epinephelus coioides grows from 24.41 g to 480.66 g within 11 months, with survival rate above 97%.The second batch of Epinephelus coioides grows from 23.36 g to 400.46 g within 12 months, with survival rate being 84.5%.The Epinephelus fuscoguttatus ♀ ×E.lanceolatus ♂ grows from 48.46 g to 511.36 g within 7 months, with survival rate being 71.24%.The Plectropomus leopardus grows from 41.13 g to 223.56 g within 12 months, with survival rate being 65.52%.The system may maintain a normal growth of Epinephelus coioides, Epinephelus fuscoguttatus ♀ ×E.lanceolatus ♂, Plectropomus leopardus and other varieties throughout the year, and reduce the cost for culturing the grouper. |
