Abstract:Based on the multi species culture ecosystem model in Sanggou Bay, numerical experiments were done by altering the kelp culture density. The aim is to probe the kelp culture carrying capacity in Sanggou Bay. Increase of the kelp culture density at the same time enlarged the frictions caused by the culture activities, which inhibited the supply of dissolved inorganic nitrogen (DIN) from the open sea. As a consequence, there is no definite increase in the kelp production. Model results for different kelp culture densities indicated that the kelp production reached the peak when the culture density was 0.9 fold of the present one.
