There is also a streamside rearing facility near Onaway, Michigan on the Black River, a tributary of the Cheboygan River, then Lake Huron. The facility is run and managed by the Michigan Department of Natural Resources, Michigan State University, and Tower Kliber. Each year hundreds to thousands of sturgeon are raised and released into Black Lake, and other surrounding areas. Adult sturgeon are caught in the river, their eggs and sperm are extracted and then taken back to the hatchery for fertilization, and left to incubate. Hatched larvae are also caught in the river with drift nets. The hatchery is open to the public, and people can also watch the hatchery workers catch the fish.
