Quantifying the effects of individual and environmental variability in fish recruitment
The effect of environmental variability on fish recruitment is analysed using simple linear growth models. It is shown that variance in an individual's environment significantly increases the probability of recruitment. It is also argued that environmental variance should lead to differences in growth rates observed in recruited fish, and in the mean observed growth rate of the overall population. These conclusions are discussed with reference to recent observations from field studies.
