| A large proliferation of Noctiluca scintillans (Dinophyceae: Noctilucidea) was observed in neritic waters off the central Cantabrian coast during late April 1995. Eggs of Acartia clausi (Crustacea: Copepoda) were the most conspicuous prey within vacuoles of Noctiluca. Noctiluca ingested 73 % of the total stock of A. clausi eggs. This intense predation on copepod eggs could potentially affect the recruitment of nauplii. The potential impact on the stock of Acartia clausi eggs and on the daily egg production of the population is discussed. There is a negative correlation between the average number of ingested eggs by a single Noctiluca cell and the abundance of Noctiluca. This fact, coupled with the lack of significant correlation between the former variable... |

| In order to provide economic indicators for fisheries, analysis of contribution and economic dependencies of the Bay of Biscay fishing fleets to major commercial species catching in the ICES VIII area is conducted. 9 species are considered (regarding the importance of their landings in this area): Sole, Norway Lobster, Sea bass, Hake, Anglerfish, Anchovy, Sardine, Cuttlefish and Monkfish. The landings data are provided by the Harmonie database of the Fisheries Information System of Ifremer and the analysis per specie is done for the 2005 year on one side and over the period 2000-2005 on the other side. A stock slip is built for each species and presents : - Key figures on landings in the Bay of Biscay (total landings, average price, number of vessels... |
