Ces structures, qui r\u00e9gulent le niveau des rivi\u00e8res et des canaux constituent un obstacle aux d\u00e9placements naturels des esp\u00e8ces aquatiques migratrices, en l\u2019occurrence l\u2019anguille europ\u00e9enne.<\/p>\n<p>Dans le cadre de ce projet, la m\u00e9tropole Aix-Marseille-Provence a confi\u00e9 \u00e0 l\u2019\u00e9tablissement public M\u00e9n\u00e9lik une intervention sur le seuil Saint-Pierre, situ\u00e9 sur le cours d\u2019eau de la Cadi\u00e8re \u00e0 Marignane.<\/p>\n<\/p><\/div>\n<div class=\"intext\"> Une esp\u00e8ce en danger critique d\u2019extinction\n              <\/div>\n<div class=\"paragraph\">\n<p>Dans le cas du seuil Saint-Pierre, c\u2019est la protection des anguilles europ\u00e9ennes qui est vis\u00e9e par les am\u00e9nagements. L\u2019esp\u00e8ce est gravement menac\u00e9e par de multiples facteurs comme la disparition des zones humides, les pollutions de l\u2019eau, le parasitisme, le turbinage, la pr\u00e9dation, le braconnage, la p\u00eache professionnelle et de loisir. Par-dessus tout, c\u2019est la fragmentation des rivi\u00e8res par l\u2019intervention de l\u2019homme qui r\u00e9duit drastiquement son taux de survie, la rendant incapable de se d\u00e9placer dans les rivi\u00e8res selon son propre cycle de vie. En effet, l\u2019anguille doit remonter les cours d\u2019eau pour grandir, un seuil peut devenir un v\u00e9ritable obstacle.<\/p>\n<p>Les am\u00e9nagements consistent notamment en la cr\u00e9ation d\u2019une rampe sp\u00e9cialement con\u00e7ue pour les anguilles dont la surface rugueuse permettra \u00e0 ces derni\u00e8res de se d\u00e9placer au-dessus du seuil Saint-Pierre.<\/p>\n<p>Les travaux pr\u00e9paratoires ont d\u00e9but\u00e9 en mai\u00a02026, et le seuil va \u00eatre partiellement repris, accompagn\u00e9 par la cr\u00e9ation d\u2019une rampe adapt\u00e9e entre juillet et mi-ao\u00fbt\u00a02026.
