New FishME project publication on the effect of rapid eradication of alien fish

Researchers from the FishME project publish evidence that the efficacy of fish eradication from mountain lakes can be high if measures are taken before fish populations get established.

Eradicating introduced trout from originally fishless mountain lakes by intensive gillnetting is effective but typically time- and resource-intensive. This study provides an example of early detection and rapid eradication as a cost-effective restoration method. It underscores the importance of monitoring fish introductions into high mountain lakes and taking immediate action to protect fragile ecosystems before costs and impacts escalate.
