Anglers, from the Prosperous Coarse Angling Club, called water authorities after spotting a milky discharge which appeared to make it hard for the fish to breathe.

The group were able to save some fish in keep nets in less polluted parts of the river before help arrived.

Waterways Ireland and the Central Fisheries Board (CFB) then managed to save most of the fish, but about 100 were killed in the incident in Grand Canal near Sallins in Ireland.

Officers from both organisations saw more than 100 dead fish near to some lock gates on the waterway and closed it – stopping the contaminated water spreading.

The polluted water was diluted and moved to an area where the impact on wildlife would be lessened.

Tests are being carried out to establish the cause of the pollution.
