Un \u00e9v\u00e9nement attendu par les agents de la R\u00e9gion en charge de la gestion des voies navigables \u00e0 Ch\u00e2teaulin et une bonne nouvelle pour la richesse de la faune locale.<\/p>\n\n\n<p>Les agents de la R\u00e9gion Bretagne post\u00e9s \u00e0 Ch\u00e2teaulin ont une mission bien particuli\u00e8re : depuis l&#8217;observatoire aquatique localis\u00e9 sur la rive droite de l&#8217;Aulne canalis\u00e9e, ils scrutent les eaux du canal et \u00e9tudient la faune locale. Et depuis quelques semaines, leurs observations sont plus pr\u00e9cis\u00e9ment concentr\u00e9es sur les poissons migrateurs qui sont de retour dans cette partie de la voie d&#8217;eau.<\/p>\n\n\n\n<p>Les deux premiers Saumons atlantiques de l\u2019ann\u00e9e 2022 ont \u00e9t\u00e9 rep\u00e9r\u00e9s le 1<sup>er<\/sup> f\u00e9vrier.&nbsp;&nbsp;Ces sp\u00e9cimens commencent ici leur remont\u00e9e du canal de Nantes \u00e0 Brest pour se reproduire en fin d\u2019ann\u00e9e sur un des affluents de l\u2019Aulne canalis\u00e9.&nbsp; Certains poissons peuvent m\u00eame effectuer plusieurs fois ce trajet p\u00e9rilleux au cours de de leur vie pour assurer leur descendance.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"un-premier-decompte-encourageant\">Un premier d\u00e9compte encourageant<\/h3>\n\n\n\n<p>Au total et depuis les premiers relev\u00e9s, on&nbsp;a observ\u00e9 pas moins de 28 Saumons atlantiques de retour dans l&#8217;Aulne, ce qui laisse pr\u00e9sager une belle ann\u00e9e 2022 pour cette esp\u00e8ce.&nbsp;<\/p>\n\n\n\n<p>La premi\u00e8re Alose (esp\u00e8ce piscicole cousine de la sardine) a \u00e9galement \u00e9t\u00e9 rep\u00e9r\u00e9e mi-mars, ainsi que&nbsp;les premi\u00e8res civelles (juv\u00e9niles d\u2019anguille) qui viennent r\u00e9aliser leur croissance dans le canal en Finist\u00e8re.&nbsp;&nbsp;<\/p>\n\n\n\n<p>En 2021,&nbsp;1297 Aloses,&nbsp;1921&nbsp;Lamproies marines et&nbsp;313 Saumons atlantiques avaient \u00e9t\u00e9 comptabilis\u00e9es sur l&#8217;ann\u00e9e
