Analyse van de bestandswijzigingen in IJsselmeer en Markermeer (BO-20-010-065)

Project: EZproject

Project Details


The ministry of Economic Affairs (EZ) is responsible for sustainable fisheries in the lakes IJssel and Marker. In 2103 IMARES presented catch advices for four stocks; bream, roach, pikeperch and perch. These advices were based on a methodology for data-poor stocks. In 2015 catch advices will again be given, based on survey data up till 2014. In 2014 a start will be made with the analysis of these data.


These advices will be supported with information gathered in a newly implemented additional survey, which starts autumn of 2014. This survey is focussed on gathering information on the population structure of the stocks. The data gathered will be used to obtain a first impression of the population structure in the lakes; are larger fish present but not caught in the regular survey or does the population consist primarily of small fish? In 2014 a start will be made with the analysis of these data.
