1 \u2013 Les premiers rayons du soleil du printemps temp\u00e8rent l\u2019eau et les UV acc\u00e9l\u00e8rent la croissance du phytoplancton, des algues et des v\u00e9g\u00e9taux sup\u00e9rieurs.<\/strong><\/em><\/p>\n\n\n\n 2 \u2013 Le plancton animal ou zooplancton<\/strong>, puis les invert\u00e9br\u00e9s aquatiques profitent de cette profusion d\u2019alimentation pour croitre et se multiplier \u00e0 leur tour. <\/em><\/p>\n\n\n\n 3 \u2013 <\/em> Les batraciens et les poissons planctonophages et omnivores<\/strong> sont les intervenants suivants qui profitent de cette chaine alimentaire. Parmi cette population on trouve les carpes, les tanches, gardons, goujons\u2026<\/p>\n\n\n\n 4 \u2013 Les carnassiers,<\/strong> en haut de la chaine alimentaire pr\u00e9l\u00e8vent leurs proies pour assurer leur alimentation. Le sandre, la truite, le brochet, le black-bass et la perche sont parmi les plus fr\u00e9quents dans nos r\u00e9gions. <\/em><\/p>\n\n\n\n <\/p>\n\n\n\n L’\u00e9quilibre de ce cycle biologique est important. De lui d\u00e9pend \u00e9galement la r\u00e9gulation des nutriments et de la mati\u00e8re organique produits par l\u2019\u00e9cosyst\u00e8me de l\u2019\u00e9tang ainsi que l\u2019\u00e9limination des compos\u00e9s toxiques et notamment, \u00a0l\u2019apport en oxyg\u00e8ne n\u00e9cessaire \u00e0 la vie des vert\u00e9br\u00e9s.<\/p>\n\n\n\n Bien g\u00e9r\u00e9, l\u2019\u00e9tang piscicole est en partie \u00ab auto-\u00e9purateur \u00bb gr\u00e2ce \u00e0 l\u2019absorption au cours de la cha\u00eene trophique de l\u2019\u00e9tang et la p\u00eache des poissons.<\/p>\n\n\n\n La partie des nutriments \u00ab non dig\u00e9r\u00e9s \u00bb s\u00e9dimentera. Leur d\u00e9p\u00f4t dans le fond de l\u2019\u00e9tang sera \u00e9vacu\u00e9 et transform\u00e9 en partie lors des vidanges et assecs r\u00e9guliers et des \u00e9ventuels apports d\u2019amendements.<\/p>\n\n\n\n Dans ces conditions, l\u2019op\u00e9ration de curage, solution extr\u00eame, devient exceptionnelle.<\/p>\n\n\n\n Nous promouvons une gestion piscicole ma\u00eetris\u00e9e des \u00e9tangs pour une p\u00e9rennit\u00e9 de ces \u00e9cosyst\u00e8mes riches et complexes. Gr\u00e2ce au conseil et \u00e0 l\u2019assistance \u00e0 la gestion d\u2019\u00e9tang, l\u2019impact biologique, paysager mais aussi la diversit\u00e9 des usages repr\u00e9sentent de nombreux avantages. <\/p>\n\n\n\n La gestion du milieu au fil du temps et l\u2019empoissonnement am\u00e9liorent la qualit\u00e9 de l\u2019eau (auto-\u00e9puration\u2026) ainsi que la biodiversit\u00e9 (am\u00e9lioration des cycles biologiques, contr\u00f4le des nuisibles\u2026).<\/p>\n\n\n\n L\u2019optimisation du cycle biologique d\u2019un \u00e9tang piscicole assure son \u00e9quilibre et se traduit par une meilleure productivit\u00e9. L\u2019\u00e9quilibre est cependant fragile et la gestion d\u2019\u00e9tang gagne a \u00eatre sous contr\u00f4le. 1 \u2013 Les premiers rayons du soleil du printemps temp\u00e8rent l\u2019eau et les UV acc\u00e9l\u00e8rent la croissance du phytoplancton, des algues et des v\u00e9g\u00e9taux sup\u00e9rieurs.
