Última Catch Per Unit Effort of deep-sea species off the continental slope to the west of British Isles. ArchiMer Girard, Marine; Lorance, Pascal; Biseau, Alain. Catch Per Unit Effort (CPUE) trends of the main target species of the deep-sea fishery were recorded for one sample trawler in two areas to the west of the British Isles, from 1993 to 1997. Considered species were the orange roughy (Hoplostethus atlanticus), the roundnose grenadier (Coryphaenoides rupestris), the black scabbard fish (Aphanopus carbo) and two squalid sharks: the Portuguese dogfish (Centroscymnus coelolepis) and the leafscale gulper shark (Centrophorus squamosus). Two sources of data have been used: the catch and effort database of IFREMER and the personal logbooks of the skipper from the sample trawler. The personal logbooks indicate the catch per haul, whereas the IFREMER database provides the catch and effort per day and statistical...

NH4+ turnover plays an important role in benthic compartment as source of nutrient for primary production. The intertidal mudflats of the Marennes-Oleron Bay are characterized by high fluctuations of sediment temperature that generally ranges from 10 to 30 degreesC during emersion periods. Influence of sediment temperature on NH4+ processes was investigated. Grass ammonification and NH4+ incorporation kinetics were studied using the N-15 isotope dilution method. The method was first adapted to these very fine sediments and applied to 2 upper sediment layers (0-2 and 2-4 cm) at different incubation times of up to 120 h. The effect of sediment temperature on gross ammonification and NH4+ incorporation rates was investigated at 10, 20 and 30 degreesC. There...
