Abstract：In this paper, in order to evaluate the carrying capacity of marine fishery resources (CCMFR) in Zhejiang province. The non-equilibrium output model and logistic model were used to calculate the Maximum Sustainable Yield (MSY) that was employed to build the assessment model of carrying capacity of marine fishery resources. It will provide a technical support for the study of carrying capacity of carrying capacity of marine resources. We collected marine fishery production data and numbers of marine fishery motor boats from 1998 to 2013 to validate these models. The results show that CCMFR was overloaded during 1998~2013 except in 2007 and 2008, and it is really closed to overloaded only in 2009. The non-available year of CCMFR were up to 81%, however, the marine fishery resources were sustainably utilized just in two years that occupied 13%. The phenomenon of overfishing was very serious in the last ten years in Zhejiang province.
