摘　　要：目前国内的活鱼运输船均采用开式循环系统,即用水泵连续抽取航道水补充到活鱼舱中,使舱内水体不断溢出舱外,以此来维持活鱼所需的水质环境.若在冬春季,航道水温低于10℃时,便无法进行活鱼运输.应用闭式循环技术,可以不受季节性气温、水温的限制,不受航道水质污染的影响,并且可以在淡水航区运载海水活鱼,全年运输时间长达12个月.改装后的“闽狮渔F259”温控活鱼运输船经过1.5a的运输试验考核,其保活运输时间超过200h;鱼水比达1∶15;存活率达98%以上;平均净载量30t/航次;获得较好的经济效益.Nowadays the live fish transportation ships in our country all adopt open circulation system, which uses water pumps to draw water out of the sea-route to supply continuously into the live fish hold, so that the water in hold can continuously overflow to maintain the water environment required to sustain live fish. However, in winter and spring ,the water temperature in the sea-route is below 10℃ and that the live fish can not be transported in this method. The application of close circulation techniques can solve this problem because it does not depend on the seasonal temperature of the air and water. and is not affected by the water pollution. It can transport live marine fish in the fresh water. The transportation time can be 12-month long. After one and a half years' experiment, the refitted temperature-control ship for live fish transportation, “Minshi Fishery F259”, can ensure the survival of live fish for at least 200 hours, the fish-water ratio to 1∶15, survival ratio to at least 98%, average payload to 30 tons per voyage. And it can gain a satisfactory economic benefits.
