There is an urgent need to evaluate the effects of anthropogenic pressures and climatic change on fish populations’ dynamics. When monitored in lakes, fish spawning is generally assessed using traditional, mostly destructive or damaging, methods as gillnetting and collection of fertilized eggs. Over the last decade, environmental DNA (eDNA) based methods have been widely developed and now offer a non-invasive alternative method to these traditional biomonitoring tools.
