Dr. Cathal Gallagher:

No, it depends on which particular programme we are looking at. We work directly on the water framework directive and look at the fish populations that contribute to the status of water bodies. In this case, we have a rota of three years over which we test various water bodies. This is defined by the EPA to a large degree. For example, in 2022 we sampled 24 lakes, 127 river sites and 12 or 13 estuaries. I will give the Deputy the exact figures. This is just one programme because we have multiple programmes. For habitat directive species, such as lamprey and others, we have a different sampling regime. For salmon, we have another sampling regime whereby we offer advice every year on 144 rivers. It is a changing dynamic depending on which programme and which particular catchment.
