The paper briefly introduces the status of the Chilean jack mackerel fishery and the trend of CPPS fishery management, and analyzes its effects on the development of the Chilean jack mackerel fishery for China, and gives some relevant countermeasures and advices: ensuring the fishing vessels to comply with the regulations of UNIA and Framework Agreement; strengthening the communications with Chile; perfecting information system and strengthening seamen training.
