A METHOD FOR CORRECTING ESTIMATED FISHERY RESOURCES IN A SWEPT AREA AND APPLICATIONS THEREOF

A method for correcting estimated fishery resources in a swept area and an application thereof. The method includes that a surveyed sea area is equally divided 5 into n survey districts, and m survey districts are selected therefrom. A trawling survey is performed in the m survey districts according to a swept area method. Using a standard trawl net within a specified time, fish catches of the m survey districts and marine environmental factors of the n survey districts are respectively obtained. A resource adaptability index SSI of respective m survey districts is 10 calculated. For all the marine environmental factors, models that reflect relationships between respective marine environmental factors and the resource adaptability index SSI are built in sequence. Statistically significant models are selected from the obtained models and used to build a TSI model. Fishery resources of the n survey districts are respectively estimated by combining the TSI 15 index and summed. In the method, the influence of the environment on the resource distribution is considered when fishery resources are calculated, and a correction coefficient based on the resource adaptability index is provided, which greatly improves the measurement accuracy, thereby showing good adaptability and having potential applications. 20
