Analyse des petits pelagiques, sardine et anchois, dans le golfe de Gascogne ArchiMer
Coiffec, Gaelle; Duhamel, Erwan; Biseau, Alain; Danzart, Marc.
Since 1993 the yearly amounts of sardine landings for the Bay of Biscay fishing ports have experienced a constant increase (10,000 tonnes in 1993); on that account sardine is the first species landed in the fishing ports of the Bay of Biscay (15,000 tonnes in 2003). It is sold 0.54 € / kg (constant price over ten years) which means a 8,100 k€ turnover in 2003 and the 12th rank in value landed in the fishing ports of Bay of Biscay. Though anchovy landings have decreased over the last ten years, especially since 2001, this species occupies the 3rd rank of the highest landings (7,300 tonnes) of the Atlantic shoreline in 2003.The decrease of anchovy landings over the last ten years may account for the high increase of its constant sale price of 1.5 € / kg from...

Compréhension des différences de distribution spatiale des anchois et de leurs œufs ArchiMer
Godet, Claire.
La campagne PELGAS participe à la gestion du stock d’anchois du Golfe de Gascogne, en réalisant une évaluation directe à la mer de la biomasse d’anchois. Pour déterminer la biomasse totale, des appareils acoustiques envoyant des ultra-sons dans l’eau pour détecter les bancs de poisson sont utilisés. Ensuite des pêches sont effectuées sur les zones détectées pour déterminer la composition des bancs (espèces, poids, longueurs…). En parallèle, les oeufs d’anchois sont comptés. A partir des données récoltées de 2000 à 2015, j’ai pu réaliser des cartes de distribution spatiale des anchois et de leurs oeufs, ainsi que des analyses statistiques afin de comprendre les différences de distribution entre les deux. Il s’avère que les oeufs sont plus au large que les...

Contrôles de la distribution spatiale de l'habitat de reproduction chez les populations de poissons. Approche multi-modèles appliquée à la plie et au merlan de Mer du Nord et à l'anchois du Golfe de Gascogne ArchiMer
Loots, Christophe.
Spawning is a crucial phase of fish life cycle as it ensures the renewal of individuals in the population. The identification of factors that influence its spatial dynamic is therefore a key feature as it will affect the reproduction success of fish population. A multi-model approach has been developed in order to identify factors that control the spatial distribution of spawning adults of plaice and whiting in the North Sea and of anchovy in the Bay of Biscay. Generalised additive models have been used to relate presenceabsence of adults and their abundances to several hypotheses of control external (geographical position and environment) and internal to the population (spatial dependency, size, age structure and memory). Models were then ranked according...

De l'utilisation de protéases industrielles pour la production de sauces de poisson ArchiMer
Le, Minh Chau.
Fish sauces are traditionally used in most Asian countries. Whatever the process, the principle is the same i.e. a fish autolysis in saline media followed by a fermentation step. Not less than 18 months are needed to obtain a brown liquid rich in salt and amino acids. This PhD work aims to determine if an addition of proteases can speed up the process while keeping the nutritional and sensorial properties. The first chapter presents the characteristics of fish sauces and the key parameters of the processes used. In the second chapter, several industrial proteases are compared each other for their capacity to liquefy the fishes in hyper saline conditions. Kinetics of proteolysis and biochemical characteristics of the resulting hydrolysates are established...

Diet, feeding behaviour and trophic activity of the anchovy (Engraulis encrasicolus L.) in the Gulf of Lions (Mediterranean Sea) ArchiMer
Plounevez, Serge; Champalbert, Gisèle.
Feeding behaviour of adult European anchovy (Engraulis encrasicolus) was studied in the Gulf of Lions (northwestern Mediterranean Sea) in relation to major abiotic and biotic factors. Observations were made during the main spawning period (summer) for two years, data were collected through hydrological pro-tiling, zooplankton hauls and fish trawling performed in areas of high anchovy density. Temperature, salinity and zooplankton biomass were stratified in the study areas, with cladocerans numerous above the thermocline whereas copepods were dominant below. Engraulis encrasicolus was strictly zooplanctivorous during the main spawning season with copepod and crustacean larvae dominating in stomach contents. Anchovy exhibited high trophic activity during the...

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".

Diversité phénotypique dans la population d’anchois commun (Engraulis encrasicolus) du golfe de Gascogne ArchiMer
Leseur, Floriane.
With the constant rising of the human population, it is essential to assess and manage the exploitation of the marine species for human consumption such as the anchovy of Bay of Biscay. Thanks to the PELGAS annual surveys, stocks of each species are estimated (biomass, repartition) and studies are undertaken to improve our knowledge about these species. Allozymic studies realized on the anchovy allowed to find a correlation between 2 alleles of the locus IDH and the habitat (depth). This allozyme has a key role in Krebs’ cycle,being speed limiting.. It enables to tolerate variations of temperature and dissolved oxygen. It would be interesting to do new research on variations in the anchovy’s environment and its migrations.

Évolution de l'écosystème pélagique du Golfe de Gascogne pendant la période 1990-2003. Conséquences sur la capturabilité des espèces ArchiMer
Villalobos, Hector.
Several small pelagic fish species contribute remarkably to world catch. Their populations are, however, characterized by large biomass fluctuations strongly affecting fisheries. The fishing gears and methods used to capture small pelagics have evolved to exploit the highly developed shoaling behavior of these species. Hence, faced to modern fishing this gregarious behavior becomes a disadvantage for fish. Fish behavior may be affected by environmental conditions and by fishing, at the same time that behavior impacts fishing. In this study, we seek to characterize the aggregative systems of small pelagic fishes inhabiting the Bay of Biscay by analyzing "acoustic images", defined as the group of echoes (planktonic layers, shoals, isolated targets) detected...

Influence de paramètres technologiques sur les propriétés sensorielles de semi-conserves d'anchois à l'huile ArchiMer
Cardinal, Mireille; Cornet, Josiane; Etienne, Monique.
As part of the contract between IFREMER and CITPPM (Confédération des Industries de Traitements des Produits de la Pêche Maritime), a study was undertaken to know the influence of sorne manufacture parameters on quality of canned anchovy. Various factors have been studied : quality of raw material, salting time in tank, ripening temperature, pressing or drying rate and also storage temperature after manufacture. This report presents only sensory results; the others analytical data are discussed in a synthetic report on this study. Sensory evaluations show a real effect of raw material quality on final product and it seems that fish glazing and a too long time of salting prevent development of ripening caracteristics. With regard to others factors; it...

L'anchois du golfe de Gascogne - Généralités et campagne de pêche en 1993 ArchiMer
Prouzet, Patrick; Metuzals, K.
The anchovy, Engraulis encrasicolus L. population in the Bay of Biscay, is described in context with other Engraulidae populations in the world. Mean landings are provided for six different species from 1974 to 1992. The great variations in the abundance (up to 200 %) of these populations, in relation to upwelling and environmental parameters are also discussed. Historical changes in the French and Spanish fleet fishing for anchovy are highlighted since 1950. The main events in the development of these fisheries are detailed. The total number ofboats in the French fleet have increased from 1987-1993 whereas the number of seiners in the Spanish fleet in that peri ad remained stable since 1980. The third part of this report describes the French fishery for...

Mathematical model and numerical simulations of the migration and growth of Biscay Bay anchovy early larval stages ArchiMer
Boussouar, Ahmed; Le Bihan, Soizick; Arino, Ovide; Prouzet, Patrick.
The paper presents a mathematical model of the early larval stage, from spawn to the resorption of the yolk-sac, of the anchovy, Engraulis encrasicolus, of the Bay of Biscay. The model describes the temperature-dependent growth and drift of passive larvae by the currents and vertical turbulence. A numerical code has been built and numerous simulations, fed by both biological (egg surveys by AZTI-San Sebastian, Spain, and IFREMER, France) and physical (circulation model by IFREMER-Brest, France) data, were undertaken. Their main features are presented and discussed here, and some conclusions on the possible utilization of the results in improving estimates of anchovy stocks by the daily egg production method are drawn.

Rapport Final – Projet CAPTAIN. Connaissances Améliorées à l'aide des Pêcheurs sur la sArdIne et l'ANchois de la façade Atlantque - Bilan 2015-2018 ArchiMer
Huret, Martin; Duhamel, Erwan; Gatti, Paul; Lebigre, Christophe; Le Mestre, Sophie; Petitgas, Pierre; Rabiller, Manuella; Guigue, Thierry; Joguet, Manon; Maillet, Jérome.
Le projet FFP Captain visait à l’amélioration des connaissances biologiques et sur la connectivité des stocks de sardine et d’anchois sur la façade Atlantique française (Manche et golfe de Gascogne). Il a reposé sur la collecte de données au travers d’une collaboration avec les professionnels de la pêche (organisations de producteurs et pêcheurs) et de l’exploitation opportuniste des pêches sur l’ensemble des campagnes halieutiques de la zone (PELGAS, EVHOE, CGFS). Ceci a permis une couverture spatiale et saisonnière optimale. Nous avons ainsi affiné la description spatio-temporelle de la reproduction pour les deux espèces, et montré une plus forte croissance ainsi qu’une densité énergétique plus élevées en Manche que dans le golfe de Gascogne. Cette...

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.
