The state of New Jersey in the United States owns and administers over 354,000 acres (1,430 km 2) of land designated as "Wildlife Management Areas" (abbreviated as "WMA") throughout the state. These areas are managed by the New Jersey Division of Fish and Wildlife , an agency in the New Jersey Department of Environmental Protection . [ 1 ]
The spawning time occurs when the water temperature reaches sixteen to seventeen degrees Celsius. [6] They lay their legs on the vegetation and along the bottom of the streams and ponds it inhabits. [4] A female brassy minnow can lay up to 2500 eggs, depending on her size, and usually releases the eggs over the course of a week.
Fathead minnow (Pimephales promelas), also known as fathead or tuffy, is a species of temperate freshwater fish belonging to the genus Pimephales of the cyprinid family. The natural geographic range extends throughout much of North America, from central Canada south along the Rockies to Texas, and east to Virginia and the Northeastern United States. [2]
The 2023 spring spawning season is crucial for the continued survival of the Clear Lake hitch, scientists say. That's because the last observed successful spawning was in 2017.
The plains minnow (Hybognathus placitus) is one of the 324 fish species found in central United States . It is a large minnow that was once a common bait fish. The plains minnow requires shallow, slow-moving streams to complete its life cycle. Pollution, dams, and introduced sport fish have caused populations to decline. [3]

[6] For example, at Rice Lake National Wildlife Refuge , Aitkin County, Minnesota, the spawning duration was 7 times longer in 2022 compared to 2021 or 2023, and the spawning timing also ...
Pumps control the current to mimic the natural flows of the Rio Grande. The bottom surface is a mixture of sand, gravel and silt. The breeding goal of the $1.7 million facility was to produce 50,000 minnows this year - with 25,000 minnows to be returned to the river and 25,000 to be retained for future captive spawning.
