co\u00fbts d&rsquo;exploitation. Le choix et la pose appropri\u00e9s de g\u00e9omembranes permettent aux aquaculteurs, aux ing\u00e9nieurs et aux \u00e9quipes d&rsquo;approvisionnement de mieux g\u00e9rer les ressources en eau, de r\u00e9duire les risques de contamination et d&rsquo;am\u00e9liorer la pr\u00e9visibilit\u00e9 des op\u00e9rations. \n<h2>Pourquoi les g\u00e9omembranes sont importantes en pisciculture<\/h2>\nLes rev\u00eatements en g\u00e9omembrane constituent une barri\u00e8re physique entre l\u2019eau du bassin et le sol naturel.
