Recreational Fisheries as a Pathway for Non-native Fishes: Czech Experiences

Abstract

Event Abstract Back to Event Recreational Fisheries as a Pathway for Non-native Fishes: Czech Experiences Lukáš Kalous1* 1 Czech University of Life Sciences Prague, Czechia Fish introductions and translocations present a serious risk for aquatic communities and are a known driver of changes in ecosystem function. Recreational fisheries is recognized as one of the important vectors of fish introductions. There are almost 400 thousands registered anglers in Czechia, which represent about 4% of the total population of the country. Here I present some examples of anglers impact on non-native fish introduction within the country but also outside the state borders. We employed a questionnaire survey on anglers behaviour, performed forensic analysis using online data from Czech anglers websites and surveyed the trade in selling live fish as bait in Prague. We found selling of non-native fishes as bait (Pseudorasbora parva, Carassius gibelio), their transport and usage. We discovered the pathway of non-native fishes from Central Europe to the Iberian Peninsula and we proved the existence of buffalo fishes, Ictiobus cyprinellus and I. niger (Catostomidae) in the rivers of Czechia. Anglers play an important role in the management of the aquatic environment and there is a need for well-communicated awareness of the potential impact of non-native fishes within their community.
