Última Etude spatiale des données collectées à bord des navires de pêche : en quoi est-elle pertinentes pour la gestion des rejets en mer ? ArchiMer Pointin, Fabien. Since 2002, the European Union (EU) Members States collect, manage and supply data for the management of fisheries and specifically of discards. In this context, at-sea observer programmes collect data on-board fishing vessels on the composition and quantity of catch, including discards. Based on these data, this study aims to analyse the spatio-temporal distribution of landings and discards so as to contribute to their management. In doing so, a mapping method based on nested grids has been developed. This method has been designed to produce pluriannual, annual and quarterly maps of landings and discards per species or group of species according to the fishing métier. A platform based on Big Data technologies has then been used with the objectives of...

The objective of this thesis was to anticipate the effects if the EU Landing Obligation (LO) implemented since the beginning of 2015 in the Eastern English Channel (EEC). To achieve these objectives, it was planned to: i) better understand seasonal spatial distribution of commercial species using on-board commercial vessels observation data, ii) compare them with the fine scale fishing effort distribution of EEC bottom otter trawlers (OTB), and iii) develop an individual-based model of fleet-dynamics, DSVM, to be integrated within the ecosystem model OSMOSE to simulate a LO. The usefulness of on-board observation data was proved for a main part of a species sample, using validation from the literature and a geostatistical indicator. Then the comparison of...
