Definition of Term

surplus production model
(english) Mathematical representation of the way fish stocks respond to fishing or other removals of individuals, with the central assumption that a large stock size, reproductive rates and rate of stock growth is slowed by self-regulating mechanisms, and that stock growth rates are faster after removals as the stocks attempt to rebuild. (See also: stock, fishery, sustainable use)
