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 […]
The 2014 juvenile eel catch on the River Shannon (from both Ardnacrusha and Parteen weir) came to only 354 Kg. This was only about 5% of the peak catches from these sites in the 1980’s, […]
As we head into March, the first runs of glass eels and elvers are arriving at the upper Shannon estuary. Soon they will be migrating up the River Shannon along with tributaries of the Shannon estuary. […]
A decision on whether to prosecute the ESB over a major kill of critically endangered juvenile European eels (or elvers) at their hydroelectric installation on the River Erne in County Donegal is still outstanding. The […]
To mitigate for the impacts of their hydropower dams, the ESB runs a number of ‘trap and transport’ schemes for upstream migrating juvenile eels (elvers), and downstream migrating silver eels. However, in this article we […]
The River Shannon has a large hydroelectric scheme in its lower reaches, and there are no bypasses for silver eels migrating downstream (or indeed for other fish such as salmon kelts and smolts). The ESB […]
