Abstract

A method of fish management includes using a sorting cage (12) that has sorting barriers (14) and storing barriers (16), and a fish counter (28) positioned relative to the sorting cage (12) for counting fish associated with the sorting cage (12). The sorting barriers (14) open to a first width while the storing barriers (16) are closed. Fish move into the sorting cage (12). The opening of the sorting barriers (14) is adjusted to a second width smaller than the first width, so that fish which are smaller than the second width can leave the sorting cage (12) while fish whose width is larger than the second width cannot swim past the sorting barriers (14). The fish counter counts a current amount of fish located in the sorting cage after an amount of time has passed.
