Dr. Marc Schmidt
PhD MSc & CEO
Dr. Marc Schmidt studied landscape ecology at the University of Münster and received a PhD in Biology from the Institute for Evolution and Biodiversity in 2006. Since 2007 he has experience in the practical use of echosounders and sonars in inland fisheries. His work with split-beam echosounders focused e. g. on spatial and temporal distribution of fish stocks, biomass estimation of pelagic fishes in lakes and reservoirs, and behavioural observations of fishes. Since 2006 his work concentrated on the practical use of multi-beam imaging sonars to investigate fish migrations and individual fish behaviour at barriers and related bypass systems.
Dr. Manuel Langkau
PhD MSc & Imaging Sonar Expert
Manuel Langkau studied Biology at the University of Cologne and got his Diploma in 2008. The thesis focused on the swimming performance of young perch in relation to foraging and growth. In 2009 he has joined LFV Hydroakustik GmbH. His work is concentrating on the practical use of imaging sonar with special respect to DIDSON and ARIS. Among the practical use of the system his work is focussing on echo characteristics of certain species, tests of new applications and enhanced data post-processing.
