The June sucker (Chasmisties liorus) is a pelagic lake-sucker endemic to Utah Lake in central Utah, USA. Development around Utah Lake, over fishing, and introduction of non-native fish contributed to changes in the Utah Lake ecosystem and the decline of the June sucker. The June sucker was listed as endangered under the Endangered Species Act in 1986 with an estimated population of less than 1000. The June Sucker Recovery Implementation Program (JSRIP) was created with signatories from state and federal agencies and community groups. There are six recovery program elements including: non-native fish management, habitat improvement, water management, genetic augmentation and integrity, research and monitoring, and education. There have been many successes and challenges in these recovery efforts. More than 100,000 June sucker have been stocked into Utah Lake, supplementing the wild population, but no natural recruitment has been documented. Non-native fish comprise 99% of the fish community in Utah Lake, but efforts are underway to investigate removal of common carp (Cyprinus carpio). Education and public awareness campaigns are in place to improve the public image of Utah Lake and the June sucker. These recovery elements combined allow for a balanced, ecosystem-based approach to the recovery of the June sucker.
