Lake Utopia rainbow smelt, large-bodied population (LURS-LbP) : updated abundance and genetic analyses. : Fs70-7/2024-031E-PDF

"Lake Utopia is part of the Magaguadavic River watershed in southwestern New Brunswick. The Rainbow Smelt (Osmerus mordax) living in Lake Utopia (LURS) represent one of the only three confirmed occurrences in Canada of co-existing genetically divergent smelt populations. Two populations of smelt co-exist in the lake: the small-bodied population (SbP) and the large-bodied (LbP). The SbP has been protected under the Species at Risk Act (SARA) since 2003. The LbP was designated as Threatened by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC 2008) because it is one of a sympatric species pair, it is endemic to a single lake with a small index of area of occupancy (6 km²), it spawns in only three small streams, and it could quickly become extinct through degradation of spawning streams from increasing development around the lake shore and impacts of the dip-net fishery"--Context, page [1].
