Lough Leane in Ireland is only the place where it is found. Eutrophication and introduction of species such as common roach Rutilus rutilus and common bream Abramis brama are the most probable threats. They are also very sensitive to pollution.
The Goureen has been found in lacustrine, pelagic, spawns in shallow bay type of habitats.
They have a life span of about five years. Males are smaller than the females. They generally feed on zooplankton, and spawn in June - July on gravel bars and gravelled shallows in and around the islands of the lake.
The adopted method for their conservation involves the identification of spawning sites and protecting them from declining water quality.
