Alimentation du merlan Merlangius merlangus L. en Mer Celtique ArchiMer
Du Buit, Marie-henriette; Merlina, Frédéric.
The importance of predation by the whiting (Merlangius merlangus ) from the Celtic Sea has been studied by analysis of stomach contents. Eight hundred and thirteen whitings have been examined during 1984-1986 period. Fish food totalizes 97% of food. It is chiefly a swimming species: no cannibalism has been observed. The daily food index varies between 2 and 4% according to the length and the annual consumption on fishes of nominal catches (11230 t for 1983) would reach 135,000 t corresponding to species already fished for human consumption and the fish meal industry.

Managing Excessive Predation in a Predator-Prey Setting: The Case of Piping Plovers AgEcon
Melstrom, Richard T.; Horan, Richard D..
Ecosystems involve interspecies interactions that can be influenced by human interventions. Prior work shows interventions that ignore these interactions cause efficiency-reducing ecosystem externalities. We show inefficiencies may also be attributable to nature, via interspecies interactions generating excessive competition or predation. Ecosystem management therefore may involve correcting both ecological and economic inefficiencies. We explore ecosystem management to correct ecological inefficiencies from predation. The inefficiencies are shown to be akin to anthropogenic externalities arising when humans harvest resources under open access conditions, and so the solution is to “regulate” predators. Viewing the ecological inefficiencies in this...

Should Ecosystem Management Involve Active Control of Species Abundances? Ecology and Society
Lessard, Robert B; University of Alberta; bob.lessard@ualberta.ca; Martell, Steven J. D.; University of British Columbia; s.martell@fisheries.ubc.ca; Walters, Carl J; University of British Columbia; c.walters@fisheries.ubc.ca; Essington, Timothy E; University of Washington; essing@u.washington.edu; Kitchell, James F; Center for Limnology, University of Wisconsin; kitchell@mhub.limnology.wisc.edu.
We review four case studies in which there is a risk of extinction or severe reduction in highly valued species if we ignore either, or both, of two ecosystem control options. “Symptomatic control” implies direct control of extinction risk through direct harvesting or culling of competitors and predators. “Systemic control” implies treating the causes of the problem that led to an unnaturally high abundance in the first place. We demonstrate, with a discussion of historically observed population trends, how surprising trophic interactions can emerge as a result of alterations to a system. Simulation models were developed for two of the case studies as aids to adaptive policy design, to expose possible abundance...
