Wildlife inventories LES POISSONS In addition to conducting standard inventories using gill, seine or hoop nets or electric fishing, Envirotel 3000 has developed fish inventory methods that have no impact on populations. Noteworthy examples of these avant-garde tools are the acoustic locating system, used in both streams and lakes, and the IchtyoS system for use in streams. Employed in combination with our flood-resistant counting weir or placed in a fishway, IchtyoS counts and measures the fish crossing the system, identifying the different species if necessary.

Our team also has the necessary equipment and experience to do sediment collection and water sampling for physico-chemical analyses. COMPANY  -  PRODUCTS ET SERVICES  -  CLIENTS  -  CONTACT
