Think that Ireland’s Marine Institute does international quality research? Perhaps it’s time to think again. This is what we exposed them using to monitor the critically endangered #eel on the River Liffey at Islandbridge during […]
Expert advice on glass eel, elver, yellow eel and silver eel management issues

Ireland’s Eel Management Plan – a poor deal for eels
Ireland’s Eel Management Plan – a poor deal for eels. Action 3a: Castletown Weir 2015. This is the new rock ramp fish pass at Castletown Weir on the River Nore. This provides a local improvement […]
As few as 2% of elvers may pass Shannon dams
It has recently been reported by Ireland’s independent scientific committee on salmon that the numbers of Annex II listed Atlantic salmon passing the dams on the River Shannon is less than 5% of the conservation […]
Monitoring silver eel turbine passage mortalities on the Lower Shannon
We are currently assessing silver eel turbine passage mortality at Ardnacrusha hydroelectric station on the Lower River Shannon. Silver eels are adult maturing eels on their spawning migration to the Sargasso Sea after spending up to 20 years (or […]
Ireland’s elver monitoring sites not operating again
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 […]
What will be done to help elvers on the Shannon this year?
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. […]
Review of ESB’s eel trap and transport programmes
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 […]
Inadequate silver eel mitigation on the Shannon
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 […]
Low elver catches at ESB dams despite upturn
The ESB have released their elver catch results for 2014, and confirm that the “elver run for the Shannon saw 354kg of elvers caught in total“. This is a very poor catch considering that this was […]
Tour of ESB’s and IFI’s elver traps, Summer 2014
In response to our work earlier in the year where we showed that ESB were not operating elver traps on the River Shannon (at either Ardnacrusha or Parteen) by the first week of May, a […]
