Population dynamics of shortlived species with emphasis on squids

Abstract

The features of short-lived fishes and invertebrates relevant to their population dynamics and exploitation are reviewed, with emphasis on methodological approaches, which could lead to improved management of squid stocks. Several models are presented which offer the possibility of reducing what presently appear to be qualitative differences in the population dynamics of fishes and squids to quantitative differences, and, hence, to render squids amenable to the kind of comparative studies which, for fish, have rendered preliminary stock assessments possible even when data are scarce
