Abstract

Abstract:

In order to evaluate the carbon sink capacity of mariculture shellfish in Guangdong Province, based on the output of mariculture shellfish in Guangdong Province in the China Fishery Statistical Yearbook, the quality and value of the carbon sink capacity of mariculture shellfish in Guangdong Province from 2016 to 2020 were evaluated with reference to tissue dry mass ratio and tissue carbon content. The results showed that the carbon sink capacity of mariculture shellfish in Guangdong Province was stable on the whole. The removal of carbon material by shellfish was 156300 tons per year, equivalent to the removal of 573500 tons of CO₂, and the annual economic value was 86-343 million US dollars. The study shows that the environmental benefits and considerable economic benefits brought by shellfish carbon sink in Guangdong Province are helpful to accelerate the realization of the "double carbon" goal in our country, and we should pay more attention to the treatment of shells at the same time.

Key words: carbon sink fishery, shellfish, carbon sink, mariculture, carbon sink accounting, Guangdong Province
