      <gmd:abstract>
        <gco:CharacterString>Le suivi des abondances de juv&#233;niles de saumon atlantique repr&#233;sente un des principaux outils de contr&#244;le de l'&#233;tat de la population de l'esp&#232;ce s'appuyant sur les oaquis scientifiques des vingt derni&#232;res ann&#233;es. Il permet d'&#233;valuer le niveau de recrutement d'un bassin sur la base de l'inventaire de ses surfaces de production et de leur &#233;chantillonnage &#224; la fin de l'&#233;t&#233;.
La m&#233;thode est devenue un &#233;l&#233;ment objectif important pour la compr&#233;hension et la gestion des stocks.
Les indices d'abondance sont obtenus en appliquant un protocole de p&#234;che &#233;lectrique normalis&#233;, &#224; savoir cinq minutes d'effort de p&#234;che (mise sous tension effective) avec un mat&#233;riel portatif agr&#233;&#233; mis en oeuvre par une &#233;quipe restreinte sur des habitats productifs de type radiers-rapides.
Sur les rivi&#232;res de Bosse-Normandie. ces indices d'abondances doivent permettre de:
* Pr&#233;ciser la r&#233;partition de l'esp&#232;ce en ce qui concerne le niveau de colonisation des principaux bassins poss&#233;dant des populations naturelles (S&#233;e, S&#233;lune. Sienne) ou b&#233;n&#233;ficiant d'efforts de restauration (Orne Vire), mais aussi sur les cours d'eau de la r&#233;gion o&#249; le saumon est discr&#232;tement pr&#233;sent ou qui rec&#232;lent des habitats favorables pour l'esp&#232;ce .
* Evaluer les programmes de restaurations engag&#233;es notamment sur les bassins de l'Orne et de la Vire.
* Fournir les r&#233;f&#233;rences de productivit&#233; n&#233;cessaires &#224; l'&#233;tablissement des modalit&#233;s d exploitation par bassin (Totaux Autoris&#233;s de Captures ou TAC) S&#233;e, S&#233;lune, Sienne, Vire et d&#233;sormais Saire.
2008 constitue la septi&#232;me ann&#233;e de prospection sous ma&#238;trise d'ouvrage de la F&#233;d&#233;ration. Le r&#233;seau &#945; pour vocation de compl&#233;ter, pour l'esp&#232;ce patrimoniale qu'est le saumon atlantique les donn&#233;es sur les peuplements piscicoles recueillies dans le cadre du R&#233;seau Hydrobiologique et Piscicole, ainsi que le r&#233;seau de la Directive Cadre Europ&#233;enne, depuis 2005 mis en oeuvre par le CSP de 1990 &#224; 2007 et d&#233;sormais par l'ONEMA depuis 2008.</gco:CharacterString>
