SUMMARY:North Platte Hatchery
DESCRIPTION:The North Platte Hatchery is open to the public and tours may be scheduled during normal working hours. Hatchery information is on display at the hatch house. \nThe North Platte Fish Hatchery opened in 1943. The facility utilizes the adjacent Nebraska Public Power District irrigation canal to feed 43 earthen ponds\, water that ultimately is returned to the canal after being used for fish production. \nThe North Platte Hatchery produces a variety of coolwater and warmwater fish species including regular production of walleye\, white bass\, blue catfish and channel catfish. On demand\, the hatchery also produces yellow perch\, black and white crappie\, wiper\, striped bass\, bluegill\, muskellunge\, tiger muskie\, smallmouth bass\, largemouth bass\, northern pike\, sauger and saugeye. North Platte hatchery staff also makes annual collections of walleye and white bass eggs and milt from regional water bodies. \nIn addition to the hatchery\, this property houses the Aquatic Conservation Facility where our team conducts mussel propagation research\, as well as other aquatic work. \nTo prevent the spread of disease and reduce stress to fish\, some areas of the facility may not be open to visitation. Contact the hatchery in advance to schedule a tour. \n
