| This report confirms interpretation criteria used in scale reading for age determination of Atlantic Salmon in freshwater and in sea water with typical examples. The difficulties for age determination of wild and reared populations by showing atypical examples are presented. Finally some recommandations to a better knowledge of Atlantic salmon population in south distribution area are proposed. |

| Plusieurs études effectuées.par divers organismes (Fédération des Pêches,S.E.P.N.B., S.R.A.E.) ont eu pour but d'analyser les eaux de l'Elorn. Le présent travail actualise les connaissances déjà obtenues sur la qualitéhydrologique de l'Elorn. L'originalité de cette étude tient en la période detemps relativement importante pendant laquelle se sont déroulées les analyses. Cette étude se révèle, en outre, complémentaire des différentes étudesmenées en rade de Brest et en particulier des analyses hydrologiques effectuéesdans le cadre du Réseau National d'Observation. En effet, il s'avère intéressant de connaître la contribution del'Elorn (1) à l'enrichissement organique et à la pollution de la rade, site exceptionnelpour le développement de l'aquaculture en... |

| Ce document a pour but de fournir l' ensemble des résultats et des observations recueillis au cours d 'une saison dans le cadre de programmes CNEXO . En effet, si certaines données sont obtenues grâce à des expériences originales et dans ce cas font ou feront l'objet de publications, d'autres constituent de simples notes ou essais qui peuvent représenter globalement une expérience susceptible de pouvoir aider à l'amélioration de techniques de production nécessaires au développement de l'activité Aquaculture - Repeuplement. Il a en outre la particularité de fournir des données sur des sujets dont l 'homogénéité n'apparaît peut - être pas évidente au lecteur élevage intensif de juvéniles. repeuplement, "Sea Ranching", gestion des stocks. Pourtant il n' y a... |

| 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. |

| Researcher since 1974 at CNEXO (National Centre for Exploration of the Oceans), then at IFREMER (French Institute for Exploitation of the Sea), I have at the same time brought to the work of researching the dynamics of exploited ichthyologic populations actions for enhanced improvement and transfer of knowledge to help managers and stakeholders administer these resources and restore them if needed. This activity led me to play a double role: that of the expert who is asked to set up "a truth judgment" on a given subject or according to a specific question, and that of the scientist faced with the judgment of his peers who strives not to go against his knowledge (i.e., that which is subject to the criticism of the scientific community). This change of... |

| An extensive restocking experiment has been undertaken in 1977 on a tributary of Elorn river in the framework of an Atlantic salmon management program of this river of northern Brittany. The results gathered during this experiment permitted the analysis of S. salar production during the juvenile and adult stages from immersion of unfed fry of Irish origin in small nursery streams. The annual production during the first year represented 72% of the total production of two years of growth. Adult runs into the nursery stream were observed between mid-November and mid-December. These runs were initiated by high increases of flow rates of the nursery stream. The whole of the adult population is constituted by late grilses whose female. Their rate of return was... |

| 1. Captures des géniteurs Les saumons ont été capturés sur la Nive au barrage de Chopolo situé sur le cours inférieur à proximité de la localité d'Ustaritz (figure 1). Cette opération a été réalisée à l’aide d’une trappe de capture aménagée dans le bassin supérieur de la passe à ralentisseurs. En tout 20 géniteurs ont été capturés sous la responsabilité du CSP et de l'INRA durant la période d'autorisation de capture du 10 mai au 31 juillet 1988. Sur ces 20 saumons, on comptait 19 femelles pour un mâle. Une des femelles était marquée et provenait d'un repeuplement effectué sur la Nivelle par l'INRA. Elle a été de ce fait écartée du lot. |

| This technical report gives the characteristics of the estuarine professional fishing located in the lower course and at the mouth of Adour river during the fishing season 2000. The fishery statistics for all the migratory amphihaline species (excepted glass-eel) are recorded according to the calendar year. For the glass-eel landings, the statistics given are relative to the fishing season (November, 1, 1999-March, 31,2000). The 2000 fishing season is characterized by a medium level of landings around 50 metric tonnes, but a high turnover, the highest of the 1985-2000 series: 1.47 Meuros. An evaluation of the state of the main exploited species is given: Atlantic Salmon, Sea Trout, Allis Shad, Sea Lamprey and Eel (glass-eel and yellow eel). The catch... |

| Heavy metals and organic pollutants were investigated in the Adour estuary (South West France) and associated wetlands using the European eel (Anguilla anguilla) as a bioindicator. Heavy metals (Cu, Cd, Zn, Pb, and Ag) were measured in soft tissue of yellow eels. Mercury (total Hg and MeHg) and organochlorinated compounds (7 PCBs, 11 OCPs) were analysed in muscle. Concentrations in muscle were in agreement with moderately contaminated environments in Europe and were below the norms fixed for eel consumption for heavy metals and OCPs. Analyses of liver showed a higher pressure of Ag and Zn in the downstream estuary than in the freshwater sites whereas Cd was lower in the estuary probably because of the salinity influence. According to quality classes 100%... |

| Introduction : Intra-basin fishing is not grasped as well, partly because of a lack of distinction between pure professional fishing units and conchological units and on the other hand because of the large amount of ships. Poorly adapted codification of the equipment found in the basin is also contributing to this lack of information. Studies on the subject do exist, but the elements necessary to publish notices are not always gathered, this is leading to the proposal of a geographical systemic analysis on the basin. The steps that are being taken are complementing the development of the Geographical Information System already in place in the basin since 1993 through DEL at the Arcachon Ifremer as well as the PECOSUDE European study ¿ caractéristiques des... |

| Situation géographique et caractéristiques de la zone prospectée par les professionnels maritimes La zone de pêche étudiée se trouve dans la région du Bas-Adour (cf carte de situation). Elle est limitée en aval par la "barre de l'Adour" et en amont par le "bec du Gave" (confluence de l'Adour et des Gaves réunis) et la première pêcherie des Gaves Réunis. Cela représente une distance prospectée de 33 km. Cette portion de l'Adour est soumise à l'influence de la marée compte tenu de son absence d'élévation par rapport au niveau de la mer. La limite de salure des eaux fixée par le décret du 4 juillet 1853 se situe au pont d'Urt (château de Montpellier) à 22 km de la limite transversale de la mer. Ainsi, l'aire d'étude se situe à la fois en zone maritime et en... |

| Along biometric characteristics, glass eel otoliths were collected during three migration seasons, in the Adour estuary, during the new moon of January. Microstructure reading and measurements of various growth zones bring information on glass eel larval life during their oceanic migration and the transition phase in estuary. The results show significant inter-annual variations of glass eels otolithometric characteristics from the point of view of their typology as of the various growth zones measured during transoceanic migration. The differences observed between the years on the typology level could be related to very fluctuating environmental conditions during recruitment. The differences in measurements carried out on the registered otolith zones would... |
