Approaches to a simplified yield-per-recruit model for crustacea, with particular reference to the American lobster, Homarus americanus / by J.F. Caddy.: Fs97-4/1445E-PDF ; Fs97-4/1445

"A simplified approach to yield/recruit analysis in crustacean populations is presented based on those information inputs normally collected from crustacean fisheries, namely, moult frequency and increment as functions of size, length-weight relationships, and gear-selection ogives. For long-lived species, size-frequency modes are unlikely to reflect age or even moult groups in the strict sense. However, a mechanism is postulated for generation of size-frequency modes (containing individuals of a mixture of age and moult numbers) in the course of an intensively prosecuted fishery with rigorously enforced size limits. The decline in log numbers per arbitrary moult interval following entry to the legal size range is suggested as an index of overall mortality"--Abstract, page iii.
