Fecundity w is reported to be an intermittent, multiple spawning species. hasler et aj. (1946) and radcliff(1931) stated that this species has a lo g breeding season, possibly spawning intermittently all summer. one pair of fathead minnows produced 4,144 fingerli.
Fathead Minnows Aquatic Biologists Inc Fathead minnows are fractional spawners, meaning they begin spawning when water temperatures approach 18 °c (64 °f) and continue until they drop below that temperature in late summer. > fathead minnows spawn between may and september when water temperature is 16 30°c, and usually at night. females spawn multiple times, up to 16 26 times, per season and generally release about 400 eggs for each spawning event. It describes the appearance and life cycle of fathead minnows, and outlines procedures for obtaining, breeding, and caring for them in the laboratory. this includes maintaining breeding populations, collecting eggs, and incubating embryos for use in aquatic toxicity studies. Spawning season for the fathead minnow starts in late may to early june when water temperature exceeds 16° c (about 60° f). it goes into mid august when the water temperatures begin to cool.

Spawning season for the fathead minnow starts in late may to early june when water temperature exceeds 16° c (about 60° f). it goes into mid august when the water temperatures begin to cool. Nearly all of a population goes through spawning in early may when water temperatures are appropriate. however, after that first spawning, females release eggs intermittently throughout the summer, with less and less frequency until mid august. Fathead minnows prefer woody structure. spawning begins when water temperatures reach 50º – 55ºf and repeats monthly until waters cool. they lay 200 to 500 eggs per spawn. stocking rate of 2 4 gallons per acre. assume 1800 – 2000 minnows per gallon. game fish illustrations courtesy of u.s. fish & wildlife service. Spawning occurs may through early august. the female deposits as many as 12,000 eggs on sub merged objects. the male remains with the eggs until they hatch. a female may spawn 12 or more times in a single summer. this fish eats algae, plant materials, aquatic insects and small crustaceans. Fathead minnows generally start spawning at 60 to 65 f (16 to 18 c) and cease at about 85 f (29 c). males establish and defend nests on the undersides (or sides) of substrates. female fathead minnows lay adhesive eggs that must stick to the ceiling to stay within the nest.
