Spatio-temporal patterns in demersal elasmobranchs from trawl surveys in the eastern English Channel (1988-2008)
Provedor de dados: 5
Autores: Martin, Corinne; Vaz, Sandrine; Ellis, J. R.; Coppin, Franck; Le Roy, Didier; Carpentier, Andre.
Elasmobranchs have life-history characteristics that make them more vulnerable to fishing than many teleost fish. As commercial landings data are usually not sufficient for the monitoring and assessment of elasmobranchs, fisheries-independent data, geostatistics and Geographic Information Systems were used to investigate the spatio-temporal patterns of sharks (6 species), skates (9 species) and stingray in the eastern English Channel. Temporal trends in relative abundance and distributions of total-length frequencies were investigated using data collected over 21 yr from an annual survey using a Grande Ouverture Verticale (GOV) trawl. Temporal trends in relative abundance were examined qualitatively in relation to the reported conservation status for the...

Bancarisation des données planctoniques des campagnes halieutiques
Provedor de dados: 5
Autores: Thomas, Amandine; Baudrier, Jerome; Gauthier, Emilie.
Cette étude fait état de la collecte des données planctoniques actuellement effectuée à bord des six campagnes halieutiques affiliées au programme DCF et optimisées pour les besoins de la surveillance liée à la DCSMM. Ce document contient des propositions de structuration en vue d’une bancarisation de ces données dans le système d’information Quadrige pour qu’elles puissent être accessibles à tous.
