Salmon Deaths in Ireland
Experts Baffled While Fish Die
The salmon are dying. In the estuary. In the tailrace. In artificial
The latest outbreak occurred in July of this year. Dead salmon were
found floating in the Erne estuary, yards from historic Inis Saimer.
They had survived migration to the seas off Greenland, were returning to
spawn where they themselves were hatched, only to die before they could
make their passage through the tailrace and the fish pass.
Itís not the first time this has happened since the ESB (Electricity
Supply Board) built a dam at Cathleenís Falls on the River Erne just
above the town of Ballyshannon in County Donegal. It wonít be the last
A similar "unfortunate event" took place in 2000.
Their natural path upriver was disrupted when the waterflow over Assaroe
Falls, below the town of Ballyshannon, was diverted into a tailrace,
leading to a fish pass that was supposed to guarantee them passage to
their eons-old spawning grounds.
The immediate impact was devastating.
Day the Salmon Died"). The long-term impact is with us to this
Until an all-out effort is made, not by local people alone, not just by
fishermen, anglers, concerned environmentalists, and tourism promoters,
but all of the foregoing, joined by civic leaders at the municipal,
county, national and international levels, the salmon will continue to
be at risk.
But there is hope. The plight of the Atlantic salmon returning to the
River Erne is no longer known only to local anglers and fishermen.
Media attention has focused attention on the salmon of the Erne, on
Ballyshannon, and on the need for the rehabilitation of the lower Erne
from the Cathleenís Falls dam down to the estuary.
Those who thought the salmon run would survive the loss of the Falls,
and a poorly, very poorly designed fish pass, have been proven wrong,
cycle after cycle. Efforts have been to promote fish stock by
aquaculture, but the wild Atlantic salmon have repeatedly fallen prey
to disease, and the experts are puzzled.
For two seasons experts at the Irish Marine Institute, the Northern
Fisheries Board, the Electricity Supply Board, and the Veterinary
Science Laboratory in Belfast, have been engaged in a study trying to
determine what is causing the salmon to die after they enter the riverís
estuary and swim upriver.
To date a number of hypotheses have been put forward, including water
temperature, waterflow, and the design of the fish pass. Singly or in
combination they could be the cause.
And what do these three suspects have in common?
They are an interference with the natural order.
We, globally, pollute the atmosphere, raising temperature.
We, through the ESB, control the waterflow.
We, through the ESB, control the fish pass.
A picture is emerging.
We cannot control global warming--yet.
But what we can control, we should control. And that means controlling
the ESB, which controls the waterflow and the fish pass.
For far too long local interests and local habitat have suffered as a
result of decisions made by this semi-state body. Its behaviour can no
longer be tolerated, whether in fish management or in pylonisation, from
Donegal to Cork harbour.
A plan has recently been proposed to rehabilitate the lower Erne and
provide a refuge for its spawning salmon.
It provides a natural solution to a man-made disaster. Such
rehabilitation has been successfully undertaken in other salmon streams
Those who are newcomers to this site may find it outlined in the item
Adoption of the plan can mean the survival of the salmon, for us and for

You are invited, indeed urged, to read the accompanying excerpts from
the "Donegal Bay Angling Guide" compiled by Paddy Donagher, which are to
be found in the history section on this site. Mr. Donagher, a
resident of Ballyshannon and member of the local Anglers' Association,
was among those who first brought attention to the dead salmon floating
in the Erne estuary below the tailrace. His history of the salmon
fishery on the Erne is well researched and written.
It may be of assistance were the authorities to investigate the
possibility of untreated effluent being discharged into the tailrace from
its northern bank.
If such were the case, the Great Pool below the desecrated Falls of
Assaroe faces the danger of becoming the Great Cess Pool, a danger to
both salmon and humans.
The recent e-coli disaster at Walkerton, Ont.,
Canada, which caused the deaths of seven people and the illness of
several hundred others, is still fresh in memory.
The photograph below (courtesy Camera World, Ballyshannon) shows the
Great Pool which once teemed with healthy salmon as they prepared to
leap the Falls.
