Presenting: Efficiency of fish-friendly intakes, bypasses associated with low bar-spacing trashracks, for downstream migration of Atlantic salmon smolt
After 15 years as a University lecturer and researcher in a team working on aquatic ecological issues (Lyon, France), Pierre Sagnes is at the head of the Onema-IMFT ecohydraulics team, in Toulouse, since 2014. One of the Onema's (the French National Agency for Water and Aquatic Environments) missions is to manage and develop research actions aiming to provide applied solutions to enhance the quality and the functioning of freshwater ecosystems. In this context, in association with the Fluid Mechanics Institute of Toulouse, the ecohydraulics team mainly works on developing technical solutions to improve fish displacements in fragmented rivers and to better understand the relationships between hydrology, fish migratory behaviour and fish habitat.
Professor (Lector) at HZ-University of Applied Sciences, Vlissingen, The Netherlands
Presenting: Fish Friendliness of Ultra Low Head Turbines
Jacob van Berkel is a scientist and entrepreneur, active on sustainable energy sources, with a focus on hydropower. As a professor (lector) at HZ University of Applied Sciences and with his consultancy company Entry Technology he serves both the public as well as the private sector. As an independent advisor to the Dutch government, he is involved in research relating to the Dutch hydropower stations and also (future) tidal power plants. Together with technical- and ecological experts he analyses energy performance and fish friendliness of low and ultra-low head turbines and investigates options for improvement.

Dr Eric De Oliveira (M) joined EDF in 2005 as engineer-researcher in biology. He is involved in 2 projects. The first deals with the impact of the power plant on the marine environment and the problem of clogging of the cooling water system. The second one concerns the fish passage at hydropower plant. His research area in this project covers migration dynamics (co-supervisor of a PhD) of fishes, fish behaviours and fish passage design using telemetry methods and other methods such as optical and acoustic cameras. With other department form EDF Lab., he develops new environmental monitoring system, such as remote sensing for seabed habitat or using acoustic methods to measure the passage efficiency in fish passage devices. Before joining EDF, from 1996 to 1998, he was in subantarctic island (Crozet Archipelago), in charge of the field activities of the project “Biodiversity evaluation and ecosystem transformation in a subantarctic island”. After, he did a PhD on fish stock assessment and especially using the geostatistical approaches. In 2003, he did a postdoc with Ifremer which was part of an Interreg MESH Project. The subject of the postdoc was to develop and build methods and model to predict the distribution of seabed habitat.

Tim has 27 years of experience in fish, fisheries and fish migration research. He started his career in 1989 at the Netherlands Fisheries Research Institute in IJmuiden (IMARES). In 1991 he was employed by the Organisation for the Improvement of Inland Fisheries (OVB), first as a project manager (1991 – 2000) and later as the head of the research department (2000 – 2005). From 2005 to 2010 he was managing director of VisAdvies, a small private company specialising in fish migration research and telemetry. From 2010 until now he is employed by ATKB. Since the beginning of his career he is working on large fish migration projects on the rivers Rhine and Meuse and at estuaries like Haringvliet, Nieuwe Waterweg and lake IJsselmeer. He is also a specialist on the effect of hydro power stations and cooling water (intakes) on fish.
Presenting: Legal requirements for fish protection and technical guidelines on downstream passage in Germany
Mr. Redeker is a Civil Engineer, specialized in water management. In 2003 he completed a post-graduate MBA degree. He has 20 years international work experience in project management, consultancy, policy and feasibility studies as well as technical designs.
