stock-recruitment model

A stock-recruitment model describes the relationship between a fish population’s adult stock (breeding individuals) and the number of new fish (recruits) born or entering the population. It helps predict how many new fish will result from a given adult population size, considering factors like environmental conditions and fish biology. This model is essential for sustainable fisheries management, ensuring harvest levels don’t harm the long-term health of the fish stock by balancing adult numbers with the production of new recruits needed for future populations.
