OSWEGO, N.Y. (AP) — NewYork's Department of Environmental Conservation is partnering with federal and Canadian agencies to restore the "bloater" fish to Lake Ontario.
Juvenile bloaters raised in a hatchery were released offshore of Oswego on Thursday, bringing the fish to the lake for the first time in 30 years. Biologists say re-establishing the species will add stability to the lake's ecosystem and sport fisheries.
The bloater is a type of deepwater cisco and was once the most abundant prey fish in the lake. Populations declined dramatically by the mid-20th century due to over-harvesting and expanding populations of invasive alewife and rainbow smelt.
Re-introducing bloaters will provide more food choices for lake trout and salmon, which can develop vitamin B deficiency if they feed primarily on alewife.
