Abstract
This study describes a recreational fishing method focused on marine catfish,Genidens barbus(Endangered-EN), through the adoption of its eggs as a natural bait during its reproductive period in southern Brazilian ecosystems. MaleG. barbusperform parental care, collecting eggs released by females after the fertilization process. Owing to this male behavioural pattern during the reproductive period, these individuals are easily caught in recreational fisheries that use eggs of the same species as a natural bait. The current adoption ofG. barbuseggs as bait may intensify the fishing pressure on its populations.Keywords
