In biology, especially marine biology, recruitment occurs when juvenile organisms survive to be added to a population, by birth or immigration, usually a stage whereby the organisms are settled and able to be detected by an observer.
There are two types of recruitment: closed and open.
In the study of fisheries, recruitment is "the number of fish surviving to enter the fishery or to some life history stage such as settlement or maturity."
