| In order to provide reliable scientific advice and support for fisheries management, it is necessary to evaluate the biological and economic sustainability of complex fisheries, such as multi-species multi-fleet fisheries. Existing policy-screening modelling tools are not fully suitable in this purpose due to either an over-simplified description of population dynamics, or due to the lack of consideration of economic aspects. In this paper, we present a package that enables quantitative bioeconomic assessment of management scenarios. Population dynamics is described through spatially- and seasonally-explicit models. Exploitation dynamics is characterized by several fishing activities with specific spatial and seasonal features, and practiced by several... |

| Assessing the impact of management scenarii on multi-species multi-fleet fisheries requires spatially and seasonally explicit simulation tools. No such tools are currently available in fisheries science. This paper presents a software that evaluates the impact of management measures on the dynamics of a complex fishery. The simulation model is generic in order to be used for different types of fisheries. Existing knowledge about each fishery is stored in a database included in the software, and may be easily modified. This includes the parameters describing each population and each fishing activity. Furthermore, the software allows for flexibility in several model assumptions. Both management measures and behaviour of fishermen in reaction to these... |

| Formal accounting sheets usually turn out being unappropriate to identify the technical or managerial elements causing the financial situation of an enterprise and to imagine the future of that enterprise as well. That is the reason why, as it has been widely developed in agriculture, a technico-economic approach linking the physical flows related to the activity of the enterprise and the resulting financial flows should be a better answer to the need of vigilance on husbandery practices and to the need of projection in the future. The realization of a computerized simulation tool taking into account some relevant technical, biological and economic criteria makes it possible to assess the consequences of investment decisions on the cash-flow and on the... |
