为了解天津市碳汇渔业潜力,本文统计了 2013-2022年天津市渔业产量并估算了碳汇生物的碳移出量.结果表明,天津市近十年平均渔业总产量为33.53万t,其中淡水养殖年平均产量27.12万t,占天津市渔业总量的80.89％.渔业碳移出量总体呈先平稳后下降再平稳趋势,平均年碳移出总量1.65万t.其中淡水养殖平均年碳移出1.09万t,占碳移出总量的66.42％,鲢碳移出量为首(0.49万t);淡水捕捞业年碳移出平均0.09万t,占碳移出总量的5.39％.海水方面,由于养殖品种中无碳汇生物,特别是缺乏贝类、藻类等碳汇品种的养殖,故不讨论海水养殖碳移出量;海水捕捞业年碳移出量平均0.47万t,占碳移出总量的28.19％.随着稻渔综合种养的快速发展,天津市可以此为契机,通过进一步完善碳汇渔业理论、提高饲料投喂效率、发挥自然渔业的碳汇功能以及优化调整养殖结构等方法与举措提高我市渔业碳汇能力,响应我国"双碳"战略,为实现"碳中和"做出贡献.
In order to understand the potential of carbon sink fishery of Tianjin,the fishery production and carbon removal of carbon sink organisms identified from 2013 to 2022 were calculated.The results showed that the average yield of fishery output of Tianjin is 335300 tons in this period,of which the av-erage annual freshwater aquaculture output is 271200 tons,accounting for 80.89％of the total.The o-verall carbon removal from fishery was stable at first,then decreased,and finally stabilized.The aver-age annual carbon removal was 16500 tons.The average annual carbon removal of freshwater aquacul-ture was 10900 tons,accounting for 66.42％.The carbon removal of silver carp was the highest,4900 tons.The average annual carbon removal of freshwater fishing industry was 900 tons,accounting for 5.39％.There was no seawater carbon sink organism was cultured,much less the carbon sink varieties of shellfish and algae.The carbon removal amount of mariculture was not discussed.The average an-nual carbon removal of seawater fishing industry was 4700 tons,accounting for 28.19％of the total.The rice-fish integrated farming is developing rapidly.Tianjin may take this opportunity to improve further the carbon sink capacity by practicing of carbon sink fishery strategy,thus improving the feed-ing efficiency,leveraging the carbon sink function of natural fisheries and optimizing aquaculture struc-tures.In this way,Tianjin may respond well the double carbon strategy of China,and contribute sig-nificantly to carbon neutrality targeting.
