The European eel is a critically endangered species. However, thousands are killed passing Ardnacrusha hydroelectric station on the Lower River Shannon each year, despite a ‘trap and transport’ scheme operated by the ESB. This is a […]
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 […]
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 […]
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 […]
When the threatened European eels cross the Atlantic Ocean to get to the Sargasso Sea to spawn, they swim in deep water. But this does not protect them from predators, researchers from the University of […]
Behaviour of stocked and naturally recruited European eels during migration – Stocked European eels also find their way towards Sargasso Sea An objection to the stocking of translocated eels as a management measure for the […]
A press release from Inland Fisheries Ireland below indicates that they are satisfied with current silver eel mitigation measures used on the River Shannon. The current approach attempts to capture outmigrating silver eels in coghill […]
