An ontologically driven method and a system for constructing a fish knowledge graph in a target region, including: combing a fish data source in the target region, constructing a fish knowledge ontology in the target region, and collecting text data and image data; according to the fish knowledge ontology of the target region, performing knowledge extraction on the text data, and measuring information content of knowledge extraction results to obtain text information weights; according to the fish knowledge ontology in the target region, performing the knowledge extraction on the image data, and measuring information content of the knowledge extraction results to obtain image information weights; according to the text information weights and the image information weights, matching the first knowledge extraction results with the fish knowledge ontology in the target region, and constructing a multi-modal knowledge graph. The processing accuracy and efficiency of the unstructured fish information can be improved.

A passive integrated transponder (PIT)-based fish school trajectory monitoring method and system for a marine ranch are provided. The method includes: using a PIT reader to obtain PIT tag information of each fish of a target fish school during a monitoring period; generating a three-dimensional (3D) fish school trajectory map of the target fish school; generating a motion sequence of each fish, inputting the motion sequence of each fish into a motion trajectory correction model, and outputting a corrected motion sequence of each fish; generating a first corrected 3D fish school trajectory map of the target fish school during the monitoring period, and generating a second corrected 3D fish school trajectory map; and generating motion information of the target fish school, and feeding back the second corrected 3D fish school trajectory map and the motion information of the target fish school to monitoring personnel.
