In most fisheries, a number of species are unintentionally caught as bycatch while attempting to catch the targeted species. While much of the bycatch problem is technological in nature due to imperfect selectivity of the fishing gear, fisher behaviour also plays a major role. How, when and...

Most fisheries worldwide remunerate their crew with a share system, where crew receive a part of the revenues or a part of the revenues less costs, rather than a fixed wage. Although labor is one of the main costs in fisheries and the share remuneration system has a strong influence on firm...

This article investigates the relationship between optimal gear selectivity and effort cost in the fishing industry We first show that optimal selectivity depends negatively on the level of effort cost, but that this relationship is not continuous. Optimal selectivity switches when real effort...

Simple macro-models are used in a two good output spaces to show that, under certain conditions that occur in very poor countries, fisheries policies aimed at concentrating rent and rationalizing excess capacity may result in declines in economic growth. In cases where displaced labour has...

The main objectives of fisheries management are generally similar throughout the world. These are often stated in policy documents such as the Common Fisheries Policy and the Magnuson-Stevens Fishery Conservation and Management Act. However, at the local level often the key objectives of...

The pressure on aquatic renewable resources has rapidly increased over past decades as a result of both sustained high demand and technological innovation. The relative scarcity of fishing resources is not new, but it seems today to have become a generalised phenomena for most aquatic ecosystems...

In this paper, we develop an empirical test of consistency in contingent willingness to pay (WTP) responses, which is based on the following a priori expectation. In economics, when an individual considers paying for public goods, his decision to pay, and his WTP are based on utility-maximising...

(article en français) Using contingent valuation method, this paper empirically examines the effects of a special accommodation tax and an entrance fee on tourists’ willingness-to-pay (WTP) for new nature reserves in the Gulf of Morbihan (France). The results show that the payment vehicles...

This paper presents a bioeconomic model of a commercial fishery facing biological invasion by an alien species acting as a space competitor for the native species. The model is illustrated in a case study of the common scallop fishery of the Bay of St-Brieuc (France), where biological invasion...
