Abstract

This paper examines the relationship between two problems in the theory of harvesting self-renewing populations with age-dependent vital rates. The first problem is to find a method of harvesting such that the yield sustainable from a population is maximized. Because of the obvious practical importance of this problem, it has been the subject of many investigations (e.g., Beverton and Holt 1957; Beddington and Taylor 1973; Doubleday 1975; Reed 1980; Botsford 1981; Horwood and Whittle 1986). The second problem is to find a method of harvesting which will maximize the capacity of a population to renew itself, given that a certain minimum crop must be taken. At first sight this problem looks relatively unimportant, and it is perhaps understandable that it has received relatively little attention.
