Carbon Sink Capacity Assessment of Mariculture Shellfish and Algae in Liaoning Province from 2010 to 2019

Abstract

In order to slow down the global warming trend, marine carbon sink gradually comes into people′s view, based on which the development concept of carbon sink fisheries has been proposed in China, which can directly or indirectly achieve the reduction of CO2 concentration in the atmosphere. In this paper, the main species of marine aquaculture shellfish and algae in Liaoning Province (Saccharina japonica, Undaria pinnatifuda, Crassostrea gigas, Mytilus galloprovincialis, Placopecta magellanicus, Ruditapes philippinarum, Sinonovacula constricta and Scapharca subcrenata) were used as carbon sink research objects, and the capacity of marine carbon sink of shellfish and algae in Liaoning Province was quantitatively assessed based on the data related to carbon sink of marine aquaculture shellfish and algae in Liaoning Province from 2010 to 2019 in the China Fisheries Statistical Yearbook. The results showed that the total amount of carbon removed by seaweed and shellfish farming in Liaoning Province during the ten-year period was about 2, 677, 300 t, which was equivalent to the reduction of 9, 825, 700 t CO2 for Liaoning Province. It also had a certain degree of promotion for China to reach the carbon peak and carbon neutral goal.
