| The works carried out during this course (March-August 2015) alowed to correct the datasets and to study the variation in catches of albacore tuna from 1967 to 2014 (except for the years 1987 to 1990) based on 3 gears: the trolling line, the line with cane and the pelagic trawl. Simultaneously, key ICCAT delivred was provide information to expert groups, with a view to defining fishing quotas. Catches released and fishing effort (defined by the number of vessels and the time spent at sea) have varied considerably over these 50 years, and have been increasing in recent years, after having decreased sharply. Fishing today is concentrated on the edge of the continental shelf, whereas it was very oceanic before. It is mainly juveniles that are caught, while... |

| This paper examines the effect of climate warming on the bio-economic performance of Bay of Biscay mixed fisheries and provides insights into the best management strategy for coping with global warming. To achieve this, a dynamic multi-species, multi-class, multi-fleets model is developed and calibrated using biological and environmental ICES and IPCC data. Fishing and economic data have been collected within the European DCF. The climate represented by the Sea Surface temperature is assumed to affect species recruitment. Three management strategies are then compared in terms of bio-economic outcomes: Status-Quo (SQ), Multi-species Maximum Sustainable Yield (MMSY), Multispecies Maximum Economic Yield (MMEY). Strategies are ranked with respect to two... |

| The laying out of an offshore site in the gulf of Lion has been realized by immersion of concrete structures in 1985. Two complementary studies have been conducted in order to estimate the impact of such artificiel reef. Gillnet fishery surveys have been done in the vicinity of the structures and also on a control site. Moreover the local profcssional fishery has been investigated for two periods of 16 months, one berore and one arter the reef immersion. The results of the gillnet surveys have already been submitted to publication and the present study displays the investigations concerning the local fishery. It has been shown by the gillnet fishing surveys that the artificial reef led in their very close vicinity to variations in marine species... |
