The Loughs Agency uses an evidence based management system to control and protect the shellfisheries and aquaculture in Lough Foyle and Carlingford Lough. This is founded on the principle of gathering good scientific information about the fisheries/aquaculture and the environment.
In recent years the Agency has broadened its approach to fisheries research to include monitoring of estuary water quality, shellfish population surveys, seed mussel surveys, seabed surveys and aquaculture surveys.
