Community Structure of Macroalgae and Estimation of Biological Carbon Sequestration in Mussel Farming of Gouqi Island
Macroalgae are one of the essential drivers of oceanic ecosystem processes,and their potential as carbon sequestrations has become a hot topic in carbon sequestration research.Biomass is a significant source of carbon sequestration for algae,and its community diversity is an influential driver of ecosystem function.For this study,12 stations were established in the mussel breeding area of Gouqi Island,and algae communities attached to floats and seedling ropes at each station were investigated for more than four quarters.The dominant species of algae in each season were analyzed.The algae community diversity index,the macroalgae biomass on a single float(g/piece),and per unit length seedling rope(g·m-1)were calculated.The total carbon sequestration of macroalgae in the raft area was preliminarily estimated according to the raft's specifications and the macroalgae's carbon content.We discussed the relationship between algae community diversity and biomass based on linear regression,which provided a reference for evaluating the additional carbon sink function of macroalgae in the raft culture area of shellfish.
