Preliminary data on horse mackerel (Trachurus spp) landings from Mauritanian waters

European fishery off Mauritania (one of the most productive and most intensively exploited regions in the world) targeted to small pelagic fish accounts for 30% of the total catches in the area. The Instituto Español de Oceanografía (IEO), through its Centro Oceanográfico de Canarias, follows up the activity of these vessels that land at Spanish port (Las Palmas de Gran Canaria, Spain), under the European Project Data Collection (Regulation (EC) 1543/2000). One of the target groups in this fishery is Trachurus spp, commercially named “JAX”. During 2008 and 2009, several samples of this group from these landings were analysed, and Caranx rhonchus was the second species of importance. The mixture of these species in the landings of this UE fleet should be determined to improve the data provided to the international Working Groups responsible for assessment of those resources.

Les petites pêches côtières et estuariennes Françaises du sud du golfe de Gascogne. Typologie des flottilles et approche socio-économique et commerciale

The European contract PECOSUDE (Small inshore fisheries of the south of Europe) accepted in 2000 for 2 years concerns French, Spanish and Portuguese partners. The aim is to assess the inshore and estuarine fisheries from Loire estuary to Portugal. Three levels of study are considered : fisheries (data 1999), socioeconomy and marketing (data 1999 or 2000). Exploitation in the 12 miles area for France and on continental shelf for northern Spain and Portugal (within 1000 m depth), as well as the fishing period lower than 96 hours was determined as the definition of this fishery for the study. Socioeconomic analyses are made only on boats smaller than 15 m. The fisheries part analyses the activity of the fishing vessels taking into account gears used, landed species, areas and fishing seasons. Within the 39 harbours of the south Bay of Biscay 1 799 coastal or estuarine vessels with 3 580 fishermen are located. Statics gears are predominant, and more than half of the vessels are polyvalent (using several gears). In 1999, landings were 20 6441 weight for 84 M¿ value. The fishing activity of these boats was also analysed by typology of the fleet, based on fishing gears and/or species landed. These characterisations allowed the application of stratified sampling for the implementation of socioeconomic investigations. The analysis of the information received from the fishermen allow to describe the production factors, to estimate their costs, as well as the turnover, the richness creation and the efficiency of the production means. The capital value of the south Bay of Biscay " ship " is established about 94 k¿, the average turnover amount to 83 k¿ and the average rate of added value to 70%. Products commercialisation vary from component to component, the importance of the sells in auction places depends on the landed species. Some valuable species are directly sold to particular
