Carbon Sink Accounting and Capacity Assessment of Mariculture in Changdao, Shandong Province

Abstract

In order to promote the development of the carbon sink fisheries and the construction of national parks in Changdao, this paper calculated the carbon sink data of marine bivalves and seaweeds in Changdao for the first time, comprehensively evaluated the carbon sink capacity of mariculture in Changdao and its influencing factors, and put forward countermeasures and suggestions. The results showed that mariculture in Changdao had a certain carbon sink capacity. The average carbon sink of shellfish cultured in Changdao from 2016 to 2020 was 29 400 tons, and the carbon sink of shellfish, especially scallop, was significantly higher than that of algae; the structure and yield of mariculture were the main factors affecting the carbon sink capacity of Changdao mariculture, and the yield of mariculture was also affected by the scale, environment and technology. In the future, the development of carbon sink fisheries in Changdao should further optimize mariculture structure, establish mariculture carbon sink accounting system, and formulate and implement related policies.
