Fish network


Vrijwillige schepnetvisser. Foto: Jelger Herder.jpg Annually collecting data about the situation of fish in The Netherlands, we aim to both gain insight into trends in populations and to detect what causes these trends. The fish montoring focuses on the species weatherfish, bitterling, spined loach, river lamprey, brook lamprey and bullheads (C. Perifretum & C. rhenanus). The waters are surveyed several times a year. All sighted species are registered. The following methods are used: visual (at night with torch), with dipnet, with sediment sampler (larvae of lampreys).
