摘要
根据2014—2023年江苏省淡水渔业养殖产量和捕捞产量数据,计算淡水渔业碳移出量和碳汇价值,并讨论了江苏省碳汇渔业发展面临的问题及对策建议。结果表明,10年间,江苏省淡水养殖碳移出量为21.55万~24.13万t,碳移出总量为226.41万t,占比较高的有鲢、鳙、鲫、草鱼、虾和河蟹;淡水捕捞碳移出量为2.17万~4.07万t,碳移出总量为34.67万t,鱼类、甲壳类和贝类分别占比为66.38%、14.54%和17.36%。根据碳汇市场价格100元/t来计算,养殖碳汇和捕捞碳汇价值年际变化分别为7908.85万~8855.71万元和796.39万~1493.69万元,江苏省淡水渔业碳汇价值合计为9.58亿元。江苏省淡水渔业养殖碳移出量及碳汇价值大于捕捞碳移出量及碳汇价值。
According to the data of freshwater aquaculture and fishing production in Jiangsu Province from 2014 to 2013,the carbon removal and carbon sink value of freshwater fisheries were calculated.Meanwhile,the problems faced by the carbon sink fishery in Jiangsu Province and the counter-measures for its development were discussed.The results showed that the carbon removal from freshwater aquaculture over the past 10 years ranged from 215500 to 241300 tons,with a total carbon removal of 2.26 million tons.The relative higher proportion was from silver carp,bighead carp,crucian carp,grass carp,shrimp,and river crab.The carbon removal from freshwater fishing ranges from 21700 to 40700 tons,with a total carbon removal of 346700 tons.Fish,crustaceans,and shellfish account for 66.38%,14.54%and 17.36%,respectively.According to the market price of carbon sink-100 yuan per ton,the values of aquaculture and fishing carbon sink during the past 10 years were 79.08-88.57 million yuan and 7.96-14.93 million yuan respectively,and the total value of freshwater fishery carbon sink was 958 million yuan.Therefore,the carbon removal and carbon sink value of freshwater aquaculture are greater than those of freshwater fishing.Furthermore,much more measures should be taken to strength the development of carbon sink capacity for freshwater aquaculture and fishing.
