Programme of Measures - Fisheries - 2015

A range of inter-related factors that affect fish spawning grounds, rearing areas, food supplies and migration routes often combine to prevent fishery populations from maintaining their productive capacity. Poor water quality, inadequate or modified flows and morphological impacts that impede fish movements and degrade physical in-river habitats are particularly damaging, whilst predation and competition from invasive species can be locally significant. In sea loughs, poor water quality and other factors such as invasive species can affect the productive capacity of transitional fish and
