An interesting paper entitled ‘RAD Sequencing Highlights Polygenic Discrimination of Habitat Ecotypes in the Panmictic American Eel‘ was recently published in the journal Current Biology by Scott A. Pavey et al. (2015). This study has found that there are differences […]
A new interesting paper has been accepted by the Journal of Applied Ecology entitled ‘Historical data to plan the recovery of the European eel‘. The authors are Miguel Clavero and Virgilio Hermoso who use historical sources to reconstruct the historical […]
Instead of opening up migration pathways for eels (and lampreys) in Ireland, our state agency Inland Fisheries Ireland (IFI) are, themselves, a major threat to eel and lamprey populations. In 2013 IFI installed this crump […]
We are very disappointed to report that many of Ireland’s national elver monitoring sites are not operational again this year in time for the elver run. This weekend we visited Inland Fisheries Ireland’s elver monitoring […]
A new paper entitled ‘Relationship between European eel Anguilla anguilla infection with non-native parasites and swimming behaviour on encountering accelerating flow‘ has just been published in the Journal of Fish Biology by Lynda Newbold et al. It examines […]
