Journal ArticleDOI
Small pelagics in upwelling systems: patterns of interaction and structural changes in "wasp-waist" ecosystems
Philippe Cury,Andrew Bakun,Robert J. M. Crawford,Astrid Jarre,Renato A. Quiñones,Lynne J. Shannon,Hans M. Verheye +6 more
TL;DR: It is doubtful that pelagic fisheries will continue to increase without major disruptions to ecosystems, and predation on zooplankton by the jack mackerel in the South Pacific provides an example of the alteration of matter fluxes in trophic webs caused by fishery removals.
Journal ArticleDOI
Global Seabird Response to Forage Fish Depletion-One-Third for the Birds
Philippe Cury,Ian L. Boyd,Sylvain Bonhommeau,Tycho Anker-Nilssen,Robert J. M. Crawford,Robert W. Furness,James A. Mills,Eugene J. Murphy,Henrik Österblom,Michelle Paleczny,John F. Piatt,Jean-Paul Roux,Lynne J. Shannon,William J. Sydeman +13 more
TL;DR: A threshold in prey abundance is identified below which seabirds experience consistently reduced and more variable productivity and provides an indicator of the minimal forage fish biomass needed to sustain seabird productivity over the long term.
Journal ArticleDOI
Impacts of Fishing Low-Trophic Level Species on Marine Ecosystems
Anthony D. M. Smith,Christopher J. Brown,Christopher J. Brown,Catherine M. Bulman,Elizabeth A. Fulton,Penny Johnson,Isaac C. Kaplan,Hector Lozano-Montes,Steven Mackinson,Martin P. Marzloff,Martin P. Marzloff,Lynne J. Shannon,Yunne-Jai Shin,Yunne-Jai Shin,Jorge Tam +14 more
TL;DR: It is found that fishing low–trophic level species at conventional maximum sustainable yield (MSY) levels can have large impacts on other parts of the ecosystem, particularly when they constitute a high proportion of the biomass in the ecosystem or are highly connected in the food web.
Journal ArticleDOI
The Benguela Current: An ecosystem of four components
L. Hutchings,CD van der Lingen,Lynne J. Shannon,Rjm Crawford,Hans M. Verheye,C. H. Bartholomae,A.K. van der Plas,Deon C. Louw,Anja Kreiner,Marek Ostrowski,Q. Fidel,Ray Barlow,Tarron Lamont,Janet Coetzee,F. A. Shillington,Jennifer Veitch,Jock C. Currie,Pedro M. S. Monteiro +17 more
TL;DR: The Benguela system is one of the four major eastern boundary upwelling systems of the world as discussed by the authors, and the role of predation has been neglected, as has the fish yield relative to photosynthesis.
Journal Article
Sustainable exploitation of small pelagic fish stocks challenged by environmental and ecosystem changes : a review
TL;DR: Analyses of the relationships between small pelagic fish and their physical environment at different time-scales illustrate the complexity of the interplay between exploitation and environmental impacts, and recommend that statistical, socio-economical, and political merits of a proposed two-level management strategy be undertaken.
