\u00c0 60 km de la ville de K\u00e9nitra, le long de l\u2019Oued Sebou, se trouve le barrage de Mograne, o\u00f9 nous avons constat\u00e9 une importante concentration d\u2019anguilles tentant de remonter vers le barrage. Malheureusement, ces anguilles ne survivent pas au fort courant. Pour y rem\u00e9dier, Nounemaroc a d\u00e9cid\u00e9 d\u2019installer un passage \u00e0 poissons<\/strong> servant d\u2019ascenseur biologique afin de prot\u00e9ger cette esp\u00e8ce menac\u00e9e.<\/p>\n\n\n\n

En s\u2019approchant de la jet\u00e9e, John d\u00e9cida de s\u2019asseoir pour admirer le coucher du soleil. Il trouva une place sur un banc et s\u2019installa, contemplant les magnifiques couleurs du ciel alors que le soleil disparaissait lentement sous l\u2019horizon.<\/p>\n\n\n\n

Les barrages ont \u00e9t\u00e9 construits pour d\u00e9velopper de grands r\u00e9servoirs d\u2019eau pouvant favoriser l\u2019agriculture \u2014 d\u2019abord artisanale, puis rapidement devenue industrielle gr\u00e2ce \u00e0 l\u2019abondance en eau. Cela a entra\u00een\u00e9 une pollution croissante due \u00e0 l\u2019agriculture industrielle en amont des barrages, et une mauvaise qualit\u00e9 de l\u2019eau en aval, emp\u00eachant toute croissance en mer. Cette pollution, souvent appel\u00e9e bouchon vaseux<\/em>, monte et descend au rythme des mar\u00e9es dans nos oueds.<\/p>\n\n\n\n

Ces retenues ont un effet n\u00e9faste que l\u2019on soup\u00e7onne peu : les poissons migrateurs (alose, saumon, lamproie, truite de mer\u2026) de nos oueds ont disparu, ne pouvant plus atteindre leurs zones de frai, bloqu\u00e9s au pied des obstacles. Seule l\u2019anguille a su s\u2019adapter en aval des oueds, car son lieu de reproduction se trouve dans les estuaires, \u00e0 l\u2019instar des poissons marins.<\/p>\n\n\n\n

Contrairement aux id\u00e9es re\u00e7ues, une partie non n\u00e9gociable des grands barrages marocains est \u00e9quip\u00e9e de passes pour poissons migrateurs comme l\u2019anguille. Cependant, la civelle ne parvient pas \u00e0 remonter malgr\u00e9 ces am\u00e9nagements, principalement \u00e0 cause de courants trop forts pour ces jeunes poissons. L\u2019anguille adulte, quant \u00e0 elle, est capable de v\u00e9ritables exploits pour remonter les cours d\u2019eau : elle peut sortir de l\u2019eau et se d\u00e9placer dans la boue sur plusieurs dizaines de m\u00e8tres pour contourner un obstacle.<\/p>\n","protected":false},"excerpt":{"rendered":"
