Les rendements par espèce de la pêche chalutière hauturière française de l'Atlantique Nord-Est entre 1972 et 1989 ArchiMer
Bertignac, Michel.
Multiple correspondance analysis and hierarchical ascending classification were used to study catch rate variations in the French deep-sea trawler fleet between 1972 and 1989. The use of these methods clarifies the sometimes complex relationships between catch rates of the main species landed within the total catch and allows a classification of the typical catch rate structures over this period. Factors such as year and fishing areas are those which best explain the observed variations; seasonal variations play a minor role. Catch rates increased and more species were caught between 1972 and 1989. The study shows the relationship between these developments and changes in fishing effort allocation strategies and in fleet structure. Trawlers which exploited...

An Experimental Analysis of a Points-Based System for Managing Multispecies Fisheries AgEcon
Anderson, Christopher M..
An industry group has proposed a novel system for managing the Northeast Multispecies Fishery. Each harvester would be endowed with a budget of points, and each species would have a “point price,” or number of points that must be paid out of his budget when landing that species. By varying the point prices throughout the season, management could redirect effort across species. This paper presents a benchmarked experimental testbed of this management system, and shows that harvesters do respond to point prices, which can be chosen to support harvest of most of the allowable catch of each species without severely over-harvesting any of them.
