Abstract: With the decline of marine fishing output, the deterioration of the coastal ecosystem and the continually growing demand for healthy and environmentally friendly seafood, the marine aquaculture has been continually prompted to entry into deep blue waters. The international community is becoming more and more fierce in the competition for ocean fishery resources. It is an important way to expand the cultivation area and improve the production output of sea products by carrying out deep sea aquaculture on a large scale of the fish species that can bring good economic benefits with high quality water resources in the deep waters. With a review and comparison of the successful cases and a focus on the transportation depression and excessive transport fleet in the present day, a technical research to transform a 300,000 DWT ore carrier to an aquaculture vessel was carried out by means of the previous successful experiences in this paper: remolding the hull structure, planning  aquaculture program and designing the matched fish allocation system, deep seawater temperature measurement and drainage system, feeding system, sewage disposal and water renewal system, catching system, etc. in deep waters, summarizing the problems to be solved, thus to promote the applicability, replicability and propagability of deep sea aquaculture and provide reference for the construction of deep blue fishery strategy.

摘要： 随着海洋捕捞产量的萎靡、近海生态系统的恶化，人们对健康绿色海产品不断旺盛的需求，促使了海洋养殖业不断迈入深蓝海域，国际社会对开发大洋渔业资源的竞争将变得越来越激烈。利用深远海优质水资源大批量养殖良好经济效益鱼类的深远海养殖，是拓展养殖区域、提高海产品产量的重要方式。通过对现有几个比较成功案例的回顾和比较，针对海上运输业萧条、运输船队过剩等现况，利用项目前期成功经验，对一条30万吨级的矿砂船改造为养殖工船展开技术研究：改造其船体结构，规划养殖方案，设计养殖配套的鱼群调拨、深层测温取水、投饲、排污换水、起捕等系统。总结并归纳待解决的问题，以推动深远海养殖可应用可复制可推广，为构建深蓝渔业战略提供参考。
