Abstract: The decision making factors and flow chart of marine fisheries production recovery post oil spill were studied,and a model library was proposed based on assistant decision making solution of marine fisheries production recovery for development of the assistant decision making algorithm of marine fisheries production recovery to deal with effects of petroleum products such as polycyclic aromatic hydrocarbons on marine organisms.The assistant decision making system of marine fisheries production recovery is built,and the proposed system can be used to select the suitable recovery model that can return the environment factors so that the water quality meet the need of marine aquaculture and poultry standard.The simulated data were used to test the system in order to test the performance of the proposed system.The results showed that the proposed system met the needs of ocean and fishery administration.
