Abstract: Potential carbon sink capacity by bivalves and seaweeds in mariculture in Liaoning Province is assessed by carbon content and proportion of dry matter in total weight in production of marine bivalves and seaweeds in Liaoning Province from 2015 to 2017. The production of marine bivalves and seaweeds in Liaoning Province was 271.28×104 t in 2015, 284.46 ×104 t in 2016， 281.50×104 t in 2017, and removal of carbon from the sea by harvests of marine bivalves and seaweeds was 27.95×104 t of carbon in 2015, 27.51×104 t of carbon in 2016, and 27.86×104 t of carbon in 2017, with average of 27.77×104 t of carbon, equal to 101.82×104 t of CO2, costing 1.60×108 Yuan RMB for CO2 capture and storage. The findings indicated that carbon sink fisheries based on mariculture of bivalves and seaweeds had remarkable economic, and ecological benefits.
