Fish Schooling and Migration,d utilization of marine fishery resources. In the marine fisheries, most fish schooling are exploited, so it is of great practical significance to study the behavior of fish schooling and migration. In addition, through the study of fish schooling behavior, the methods of artificial schooling or con
