|Scientific Name:||Alosa killarnensis|
|Species Authority:||Regan, 1916|
|Red List Category & Criteria:||Critically Endangered B1ab(iii) ver 3.1|

The species is only found in one location, Lough Leane (19 km²) in Ireland where it is threatened by eutrophication, and may potentially be impacted by introduced species (cyprinids such as Rutilus rutilus and Abramis brama).
|Range Description:||Lough Leane (19 km²) (Killarney, Eire).|

|Population:||The population was considered small in 1993 (Whilde 1993).|
|Habitat and Ecology:||
Lacustrine, pelagic, spawns in shallow bays.
Lives up to five years. Females are larger than males. Spawns in June-July on gravel bars and gravelled shallows around large islands of the lake. Feeds mostly on zooplankton. Highly sensitive to pollution (Whilde 1993).
|Major Threat(s):||Eutrophication of the Lough Leane is a current threat to the species. The presence of excessive algal growth overlying littoral gravel may impede spawning. Also recently cyprinids such as Rutilus rutilus and Abramis brama have been recorded in the lake, and they may represent a threat to the species through competition.|
|Conservation Actions:||The identification of spawning sites in Lough Leane and their protection from declining water quality and development works is a priority to ensure the future survival of the species (Doherty et al. 2004).|
