Aquatic life is continuously exposed to man-made threats, potentially exposing some species to the threat of extinction. Human activities that have an adverse impact on aquatic life are now regulated by a strict legal context, notably through the Water Framework Directive in Europe and other similar legislation around the world (CWA 316b, …). Profish offers a broad range of services and products, based on a scientific expertise acquired and cultivated primarily in the field, making it possible to reconcile human activities with legal requirements. Our Consultancy Service offers support for industrial projects and environmental restoration projects. We have developed an expertise in biological monitoring of fish populations, in terms of both demographics and behaviour. Securing fish migration routes (dam by-passes, avoiding industrial water intakes) is our premier field of expertise. Profish also offers technological solutions directly affecting fish behaviour. Our infrasound barrier, a world first, reduces fish mortality by 80 % at cooling water intakes, while our NEPTUN electrical barrier can be used for wider applications, in the hydro-electric sector and also for more specialised applications.
