| The fishery for common sea bass (Dicentrarchus labrax) is the fourth most important French metropolitan fishery in value terms, with approximately 5 500 tons landed, and a total turnover of about 52 million euro in 2006. Given its high market value, sea bass is targeted by a range of métiers, resulting in interactions between a large number of fleets. The annual contributions to catches and landings of each of these fleets are highly variable, as are their level of economic dependence towards the species. Sea bass is also an emblematic species for recreational fishermen. Currently, there is no limitation on total allowable catch in this fishery, nor are catch allocations specified at the individual vessel level. The fishery thus faces the traditional... |

The aim of this thesis is to simulate the response of the French fishing fleets to introduction of alternative management scenarios for the sea bass fishery. Simulation results emphasize the diversity of anticipated impacts of alternative management scenarios from both a... |

| Fisheries management must address multiple, often conflicting objectives in a highly uncertain context. In particular, while the bio-economic performance of trawl fisheries is subject to high levels of biological and economic uncertainty, the impact of trawling on broader biodiversity is also a major concern for their management. The purpose of this study is to propose an analytical framework to formally assess the trade-offs associated with balancing biological, economic and non-target species conservation objectives. We use the Australian Northern Prawn Fishery (NPF), which is one of the most valuable federally managed commercial fisheries in Australia, as a case study. We develop a stochastic co-viability assessment of the fishery under multiple... |

| Sustainable management of natural resources, and in particular fisheries, must take into account several conflicting objectives. This is the case in the French Guiana shrimp fishery for which profitability objectives imply a reduction in the fishing activity. On the one hand, this fishery has negative externalities on marine biodiversity due to discards. On the other hand, this fishery has positive externalities on the economy of the local community and interestingly enough on a protected seabird species in the area (the Frigatebird that feeds on discards). In this paper, we examine the viability of that system considering two sustainability objectives: an economic objective in terms of the profitability of the fishing activity, and a conservation... |
