The maritime fisheries and mariculture guidance law passed in 1997 specifies that with the perspective of renegotiation of the common fisheries policy in 2002, a report on the special conditions of inshore fisheries be drawn up by the Government. To do so, the Minister of Agriculture and Fisheries entrusted this task to three experts, who are the authors of this report. In accordance with their remit, the situation of fisheries in territorial waters and estuaries of metropolitan France and the four DOM overseas departments ( counties) was examined, in the framework of meetings with professional fishermen, administrations, elected officials and scientific organisations. The first part situates fishing activities in coastal areas within the overall context... |

A growth and survival model of the early life stages was run along virtual drift trajectories tracked in a hydrodynamic model to simulate the annual recruitment process of anchovy (Engraulis encrasicolus) in the Bay of Biscay (NE Atlantic). These biophysical simulations concerning three different years were analysed in order to investigate the influence of environment and spawning dynamics on the survival of larvae and juveniles. The location of space-time survival windows suggested major environmental mechanisms involved in simulated recruitment variability at the different scales - retention of larvae and juveniles in favourable habitats over the shelf margins and turbulence effects. These small-scale and meso-scale mechanisms were related to the... |

Individual fish growth depends on internal population factors such as phenotypic variability as well as external factors such as past environmental conditions (temperature, food) and selective mortality (predation or fishing). In the anchovy, growth in the first year is key to population dynamics as it determines the potential energy allocated to reproduction as well as the capacity to occupy off-shore habitats. Further, in the recent past, the anchovy in the bay of Biscay has experienced collapse and recovery and the role played by growth in this history is unknown. Since 2001 with the spring acoustic survey series PelGas, we have monitored individual fish growth by measuring in the otolith the increments between annual rings, in addition to age... |
