Onderzoek naar invloed van vismigratievoorzieningen op de glasaalindex bij Den Oever (Correctiefactor glasaalindex) (BO-20-010-127)

Project: EZproject

Project Details


In the year 2016 measures will be taken to improve the possibilities for fish to migrate between the Wadden Sea and the lake IJssel. These measures could result in a trend reversal for the glass eel monitoring at the Stevin Sluizen in Den Oever that forms Europes longest lasting data series for the glasseel index. In 2015, 2016 and 2017 field data has been and will be collected concerning thedistribution of glass eels with and without the measures and infrastructure to improve fish migration in place. This datasets will be used to identify if a trend reversal in the dataset can be expected after 2015. And if that is the case, to determine a correction factor can be applied to maintain the continuity of the dataset.
