Models of population dynamics in which per capita reproductive success declines at low population levels (variously known as depensation, the Allee effect, and inverse density-dependence) predict that populations can have multiple equilibria and may suddenly shift from one equilibrium to another. If such depensatory dynamics exist, reduced mortality may be insufficient to allow recovery of a population after abundance has been severely reduced by harvesting. Estimates of spawner abundance and number of surviving progeny for 128 fish stocks indicated only 3 stocks with significant depensation. Estimates of the statistical power of the tests strengthen the conclusion that depensatory dynamics are not apparent for fish populations at the levels studied.
在人均繁殖成功率在低种群水平时下降的种群动态模型中（有多种称谓，如种群补偿不足、阿利效应和逆密度依赖性），预测种群可能具有多个平衡点，并且可能突然从一个平衡点转变到另一个平衡点。如果存在这种补偿不足动态，在种群数量因捕捞而大幅减少后，降低死亡率可能不足以使种群恢复。对128个鱼类种群的产卵亲体数量和存活后代数量的估计表明，只有3个种群存在显著的补偿不足。对这些检验统计功效的估计强化了这样的结论：在所研究的水平上，补偿不足动态在鱼类种群中并不明显。
