Stillwater Fish Monitoring Project


Loughs Agency conducts Water Framework Directive compliant Stillwater fish stock assessments within the Foyle and Carlingford areas. A small rolling programme of lake fish surveys commenced in 2010 to gain a better understanding of fish composition and abundance of the standing waterbodies within the Foyle and Carlingford areas. The information collected can be used for many purposes ranging from formal Water Framework Directive classification, a baseline survey for use in the scrutiny of any future development proposals and for contributing towards the sustainable development of the angling amenity.

The spatial and temporal data including species presence and their relative abundance is important to resource managers and anglers alike. Monitoring changes over time facilitates management decision making.

Prior to a lake fish survey being conducted accurate bathymetry (depth information) is required. Loughs Agency conducts bathymetry mapping surveys utilising its own hydrographic survey equipment.
