Fish Stock Survey of Lough Nasnahida, July 2021

The lake is not heavily fished and appears to be in a natural state with good spawning streams. The lake is categorised as typology class 1 (as designated by the EPA for the purposes of the Water Framework Directive), i.e. shallow (<4m), less than 50ha and low alkalinity (<20 mg/l CaCO3).

The lake has been surveyed on three occasions since 2009 (2009, 2012 and 2015). Brown trout have dominated fish stocks on all recent survey occasions. Eels were also captured during each survey.

This report summarises the results of the 2021 fish stock survey carried out on the lake using Inland Fisheries Ireland’s fish in lakes monitoring protocol. The protocol is WFD compliant and also provides insight into fish stock status in the lake.
