Abstract

Based on the in situ investigations on primary production and secondary production in the Daya Bay,the potential fishery production and the maximum sustainable yield in this region were estimated.The results showed that the average primary production in the Daya Bay were 765.23 mgC·m^-2·d^-1 and 1786.33 mgC·m^-2·d^-1 in spring and summer respectively,and the average secondary production were 175.23 mgC·m^-2·d^-1 and 678.95 mgC·m^-2·d^-1 in spring and summer respectively.The potential fishery production based on the Tait's model and the Cushing's model were 3.30×10⁴ ton and 4.78×10⁴ ton respectively.Further analyzing results showed that changes of community structure in basic trophic levels may lead to overestimate the actual fishery production in the bay when basic biological productions were used to the estmiations,high community biodiversity,healthy ecosystem structure and function should be the primary basis for sustaining quantity and quality of the fishery production.

Key words： Daya Bay primary production secondary production potential fishery production
