Abstract: A carbon sink enhancement method based on oyster-Undaria pinnatifida integrated aquaculture is performed as follows. Oysters with similar size and appearance are selected, washed and evenly spread onto a bottom of an incubator, to which 5-15° C. seawater is added. A rope is fixed on an upper side wall of the incubator. Undaria pinnatifida seedlings are spacedly clamped on the rope for spaced hanging culture. A wet weight ratio of the oyster to the Undaria pinnatifida seedlings is 6-8:1. The incubator is placed under sunlight for mixed culture, during which the incubator remains closed without water replacement. The oysters or the Undaria pinnatifida seedlings are taken out when the oyster reaches a meat yield of 10% or more or a length of the Undaria pinnatifida seedlings is larger than 100 cm. Seawater samples are collected to detect water quality parameters for carbon sink assessment.
