INLAND FISHERIES IRELAND is investigating after over 1,200 dead fish were found on a spawning tributary to one of our main salmon fishing rivers.
The fish kill is on the Owentaraglin River, a tributary of the Munster Blackwater River, in north-west Cork.
Fisheries officers discovered more than 1,200 fish mortalities over a 2km stretch of the river near the village of Kiskeam.
Raw slurry
Inland Fisheries Ireland says it is following a definite line of inquiry.
They say the cause of the fish kill is believed to be a large discharge of raw slurry into the waterway, which they describe as an important spawning river.
Fish species affected on the river include salmon, brown trout, eel and stickleback.
Significant numbers of gravid hen salmon were among the mortalities.
Significant damage
Aside from the large number of fish killed, there was significant damage to the spawning beds and wider aquatic habitat, which will have implications for the fish population in the area into the future, Inland Fisheries Ireland warned.
Spokesman Sean Long said:
It will take years for River Owentaraglin to recover to its former condition as a result of this pollution.
Inland Fisheries Ireland is reminding farmers of the importance of complying with EU Regulations on the storage or movement of slurry.
Recreational angling contributes €836 million to the Irish economy annually and supports upwards of 11,000 jobs, often in rural and peripheral communities.
Since 2010, Inland Fisheries Ireland has been responsible for the conservation, protection, management, marketing, development and improvement of our inland fisheries and sea angling resources.
Inland Fisheries Ireland (IFI) is asking the public to call its 24-hour confidential hotline to report suspected discharges into rivers: 1890 34 74 24 or 1890 FISH 24.
