A Bioeconomic Model of Partial Closures and Habitat Effects - The Case of a Migratory Fish Species

Creator:

Armstrong, Claire W., Armstrong, Richard J., and Reithe, Siv

Abstract:

A bioeconomic model allowing different degrees of harvesting closures for two sub-stocks consisting of mature and immature fish is presented. Hence the model opens for partial closures of fisheries on both sub-stocks. Migration between the two sub-stocks is defined as recruitment of the young to the mature sub-stock, and egg...

Bioeconomic adaptive management procedures for short-lived species: A case study of Pacific saury (Cololabis saira) and Japanese common squid (Todarodes pacificus)

Creator:

Hoshino, Eriko, Milner-Gulland, E. J., and Hillary, Richard

Abstract:

Short-lived fisheries stocks are subject to large fluctuations in abundance and respond rapidly to many factors including changes in oceanographic conditions, biological interactions and fishery exploitation. Management of such species requires a flexible, adaptive framework that responds rapidly to a changing environment, although such schemes are rarely operationalized. In this...
