Afkreeften in openwatersystemen : Onderzoek naar beheersvisserij van invasieve rivierkreeften in Dordtse wateren

Roessink, Ivo; Ottburg, Fabrice


As a result of the incorporation of invasive freshwater crayfish onto the European regulation on Invasive Alien Species, this group of animals has drawn the attention of water managers. Commercial fishery has been suggested as a measure to control or eradicate populations of alien crayfish. However, it is not clear how and where the commercial practices of the fisherman and the needs of water managers converge. This field study provides answers to some of the basic questions regarding the efficiency of different traps, the impact of fishing on the population and the so-called unintended by-catches.
