Última Bancarisation des données planctoniques des campagnes halieutiques ArchiMer Thomas, Amandine; Baudrier, Jerome; Gauthier, Emilie. Cette étude fait état de la collecte des données planctoniques actuellement effectuée à bord des six campagnes halieutiques affiliées au programme DCF et optimisées pour les besoins de la surveillance liée à la DCSMM. Ce document contient des propositions de structuration en vue d’une bancarisation de ces données dans le système d’information Quadrige pour qu’elles puissent être accessibles à tous.

Ano: 2019 URL: https://archimer.ifremer.fr/doc/00513/62496/66807.pdf Direct assessment of anchovy by the PELGAS04 acoustic survey ArchiMer Masse, Jacques; Beillois, Pierre; Duhamel, Erwan. An acoustic survey was carried out in the bay of Biscay from April 27th to May 25th on board the French research vessel Thalassa. The objective of PELGAS04 survey was to study the abundance and distribution of pelagic fish in the Bay of Biscay. The target species were mainly sardine and anchovy but had to be considered in a multi-specific context. The results have to be used during ICES working groups in charge of the assessment of sardine, anchovy, mackerel and horse mackerel and in the frame of the Ifremer fisheries ecology program "resources variability".

Ano: 2006 URL: http://archimer.ifremer.fr/doc/2006/acte-2291.pdf Les couches diffusantes du golfe de Gascogne : caractérisation acoustique, composition spécifique et distribution spatiale ArchiMer Remond, Barbara. Fisheries acoustic data are continuously collected during ecosystemic surveys to detect sh schools of commercial species and to quantify the sh abundance. These multifrequency data also contain information about smaller target aggregations producing ubiquitous Sound Scat- tering Layers (SSLs) on the echograms, with quite diverse shape, frequency responses and taxonomic compositions. In this work, we focus on the SSLs observed in spring in the Bay of Biscay during the PELGAS surveys. The objectives are: i) to classify SSLs, ii) to describe their spatial meso-scale distribution, iii) to investigate their relationships with oher exosystme components, and iv) to investigate the taxonomic composition of resonant SSLs at ne scale.

Ano: 2015 URL: http://archimer.ifremer.fr/doc/00267/37784/35859.pdf Sardine series in PELGAS surveys : PELGAS 2000 to 2005 ArchiMer Masse, Jacques; Duhamel, Erwan; Delaunay, Damien. Survey data from 2000 to 2004 were used to analyse whether sardine show a preferential distribution in relation to bottom depth and/or latitude. For this analysis, four strata were considered; North or South of latitude 46°N (separating VIIIa and VIIIb) and bottom depths deeper or shallower than 110m. Sardine length distributions are plotted as the proportion of small (< 18.5 cm) or big (larger than 18.5 cm) fish on the samples over the years. This division was chosen to take into account the bimodal structure of sardine length distributions (usually with a "valley" at 18.5 cm fish length). Small fish (mainly 1 year old) are generally found close to the coast and preferentially in the southern part. The year 2003 is different to the others but this year...

Ano: 2005 URL: http://archimer.ifremer.fr/doc/2005/acte-2294.pdf The French anchovy fishery ArchiMer Duhamel, Erwan; Biseau, Alain; Masse, Jacques; Villalobos, Hector. The french fishery of anchovy is divided in two groups defined by gears : purse seine and pelagic trawl. The average length of these vessels is about 20m. This fleet is very opportunistic : all trawlers are using several trawls during the year, to catch sometimes bass, tuna, hake, or scampi, and purse seine are mainly fishing sardine. Each year, the main anchovy catches are provided by pair trawlers. Purse seiners operate often in coastal areas (<10 nautical miles); trawlers may operate until 50 nautical miles offshore but are banned inside the three miles coastal zone. The pair trawlers may operate from Basque country to western Channel according to fish availability. Purse seiners usually stay around their home harbour.

Ano: 2004 URL: http://archimer.ifremer.fr/doc/2004/acte-2296.pdf The French sardine fishery ArchiMer Duhamel, Erwan. This approach of the French sardine fishery shows mainly that pelagic trawlers are targeting less and less sardine, year after year. In an assessment approach, it would be necessary to define an estimation of fishing effort, but it will be very difficult. We are able to compt the number of fishing days, but not the time of fishing (or number of shoots for example for purse seiners) or time of searching schools. So, accessibility and catchability could be certainly more accurate than the fishing effort for assesment purposes.
