Les pêcheries de buccin (Buccinum undatum L. : Gastropoda) du Golfe Normand-Breton. Eléments de gestion de la ressource ArchiMer
Santarelli Chaurand, Leonardo.
The whelk (Buccinum undatum) fisheries in the gulf between Brittany and Normandy have grown quickly over the past ten years. In 1983, 35 potters and 14 dories from Granville harbour and the Blainville maritime station landed 3,900 tonnes of whelk (for a value of 7.5 million francs). In spite of a sharp drop in profitability, the number of fishers is still growing. This study aimed to provide decision-making elements for rational management of the resource : stock abundance, catches per unit effort, mortality due to fishing effort and biological properties. In order to assess the impact of measures to organise the fishing effort on total catches in balance, two predictive models were used: Pella and Tomlinson's generalised production model and Ricker's...

FLR: an open-source framework for the evaluation and development of management strategies ArchiMer
Kell, Laurence T.; Mosqueira, I; Grosjean, P; Fromentin, Jean-marc; Garcia, D; Hillary, R; Jardim, E; Mardle, S; Pastoors, M.a; Poos, J.j.; Scott, F; Scott, R.
The FLR framework (Fisheries Library for R) is a development effort directed towards the evaluation of fisheries management strategies. The overall goal is to develop a common framework to facilitate collaboration within and across disciplines (e.g. biological, ecological, statistical, mathematical, economic, and social) and, in particular, to ensure that new modelling methods and software are more easily validated and evaluated, as well as becoming widely available once developed. Specifically, the framework details how to implement and link a variety of fishery, biological, and economic software packages so that alternative management strategies and procedures can be evaluated for their robustness to uncertainty before implementation. The design of the...
