Research On The Measurement And Price Accounting Of Carbon Sequestration Of Cultured Shellfish And Countermeasures

With the carbon sequestration of cultured shellfish gradually coming into view,the fixed blue carbon sink of cultured shellfish,as a typical Marine ecological product,has both ecological and economic value.The trading of the farmed shellfish carbon sink through the blue carbon market will bring additional income to the farmers,and at the same time,the ecosystem services will be compensated through the trading of the carbon sink,so as to realize the breakthrough of the effective combination of ecology and economy of the coastal carbon sink fishery.In addition,engaging in carbon sequestration aquaculture activities can improve the Marine environment and improve the overall social benefits.Farming shellfish carbon price calculation of Marine ecological compensation "recover" is the emphasis and difficulty in facing,the reason is that farming shellfish carbon sinks is a kind of invisible ecological products,farming shellfish aquaculture in the complicated environment makes carbon measurement link harder,current farming shellfish carbon measurement method and standard of relatively weak,restricting the development of the carbon price calculation.In order to solve the farming shellfish in the process of carbon sinks pricing carbon measurement method is not perfect,based on the method of carbon change farming shellfish based formula to supplement and improve carbon,carbon added biological sediment and fouling organisms two measurement indicators,and the adhesion shellfish carbon sequestration and biological deposits of the two parts measurement indicators,From the experience of other scholars concluded that formula,experience value,improve the calculation method of related parameters,reduce the influence of subjective factors in the process of acquiring parameters,increase carbon sink measurement method to improve the rationality and universal degree,end up with more perfect farming shellfish breeding environment total carbon measurement model;Taking carbon sink metering method as the starting point,the carbon sink pricing method--cost-benefit model of the selected Marine pasture was improved,and Dongfang Yunxi Marine Ranch was selected as the study area for case calculation,and the carbon sink prices of three farmed shellfish were obtained:The carbon sink price of bay scallop is 45 yuan/ton,that of chlamys farreri is50yuan/ton,and that of ruffed oysters is74 yuan/ton.Analysis and calculation results get the following conclusion: the improved farming shellfish total carbon measurement formula can be more comprehensive reaction of carbon sequestration mechanism,breeding environment resulting from the per capita amount of carbon farming shellfish about 1.4 ～ 2.1 times of academic results,including biological effect is most obvious increase of sedimentary carbon remit,accounted for about 91% of the carbon sequestration shellfish shells and software;By carbon price accounting model calculation farming shellfish carbon price,the total amount of carbon sequestration and cost-benefit factors are affecting farming shellfish carbon price’s two most important factors,higher carbon quantity can get lower price of carbon sinks,in the long term,within a certain range,the price of carbon sinks will reduce with the increasingly improvement of carbon measurement.Carbon sink metering method improvement and the price of carbon sinks accounting related research results,is advantageous to the rich blue carbon sinks field on the Marine carbon sink in the GEP accounting of fisheries ecological service value accounting,to provide certain reference for seawater shellfish aquaculture industry subsidies,provide reference data for the establishment of ecological compensation amount,promote the income of fishermen,boost the enthusiasm of the production,Promote the coordinated development of environmental and economic benefits of mariculture industry.
