Fisheries around the world are managed with a broad range of institutional structures that usually involve institutional systems that provide incentives to individual operators that lead to behaviour consistent with conservation.
Spatial dynamics of female snow crab (Chionoecetes opilio) in the eastern Bering Sea

A 25-year time series of survey data was analyzed and ontogenetic stages were defined in terms of a "shell condition index" calibrated with radiochemical methods, supporting the hypothesis that the variable tracked is near-bottom temperature.

Precaution in the harvest of Methuselah's clams the difficulty of getting timely feedback from slow-paced dynamics

Geoduck (Panopea abrupta) stocks are perceived as stable and their fisheries as sustainable, but this may reflect a mismatch between slow-paced dynamics and short-term perception, which could accelerate population declines and drive an apparently sustainable fishery to collapse.
Model of dredging impact on Dungeness crab in Grays Harbor, WA

Abstract : The effects of dredging on marine organisms have been an issue for several decades. Studies have shown effects on the composition of infaunal communities, including disruption and…

The hypothesis that B. purpuratus from the earlier Quaternary marine terraces of Patagonia likely result from a relatively recent (post-LGM) colonization originated from populations in the south-eastern Pacific is proposed.

Strengthening of a traditional territorial tenure system through protagonism in monitoring activities by lobster fishermen from the Juan Fernández Islands, Chile

A small-scale rock lobster fishery has operated for decades in the Juan Fernandez Archipelago of Chile under a traditional territorial tenure system that has put an effective cap on the size of the fishing force, but time series of basic indicators other than annual landings have not been collected on a regular basis.
Spatial dynamics of snow crab (Chionoecetes opilio) in the eastern Bering Sea-putting together the pieces of the puzzle
- C. Parada, D. Armstrong, B. Ernst, S. Hinckley, J. Orensanz
- Environmental Science
- 2010
A conceptual model of snow-crab spatial dynamics that integrates empirical information with new results from modeling of circulation and larval transport is presented, for the first time, and predicted settlement regions match historical regions of abundance of immature crabs and are consistent with observed fields of suitable near-bottom temperature.
