Stock recruitment is a concept in population dynamics and fisheries science that describes the relationship between the size of the breeding or spawning stock and the number of young individuals that survive to join the population in the next generation. In practice, recruitment is the inflow of new individuals into the exploitable stock, while the stock refers to the mature, breeding portion of the population. The basic premise is that larger parental stocks generally produce more recruits, but the relationship is modulated by density dependence and environmental conditions.
The most common models describing stock-recruitment relationships include the Beverton-Holt model and the Ricker model. The
In management, stock-recruitment relationships are used in stock assessments to forecast recruitment under different spawning stock
