2.1.3 Carbon release model for fish
In short, all the fish-released carbon, C release, can be divided into FC release andBC release, based on its original source, and classified into DOC, CO2, and PC, based on its final form. Therefore, a carbon release model is proposed:C release =FC release+ BC release (Figure 1). This model enables us to calculate the amount of DOC, CO2, and PC released by a fish if the carbon release parameters of the fish are known.
