Inland Fisheries Ireland says the discovery of a dead shark in the River Erne is a "cause for concern".
Last Friday, IFI officers in Cavan were alerted that a small dead shark was floating in the River Erne at Belturbet.
Officers removed the carcass for analysis and it's believed that it was a small spurdog shark, measuring around one metre in length.
In a statement to Northern Sound, IFI said "early indications are that the spurdog shark was caught at sea, with a rod and line, and possibly dumped at Foalies Bridge in Belturbet".
Inland Fisheries Ireland advocates a 'catch and release' approach with shark species, and strongly condemns the dumping any shark or fish species, dead or alive, which can lead to biodiversity or pollution issues within rivers or lakes.
Anyone with information regarding the incident is encouraged to contact Inland Fisheries Ireland.
