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. Fractional spawning can result in 16 to 26 spawning events per female and an annual fecundity of 6,800 to 10,600 eggs per female.
Generally, minnows breed with the slightest rainfall and within a wide temperature range. Contrary to the long-standing presumptions, climate change poses 'negligible' threat to minnows' reproduction. Minnows are also flexible in attaining pre-spawning fitness, which makes them avoid 'skipped spawning' decisions while facing climatic variabilities.

Feeding time is usually dawn and sunset. The brook stickleback does have active competition mostly from minnows, but feeding times are different, along with diet. [4] Spawning occurs in midsummer. Males secure a territory, build a nest, and mate with females. Males provide protection for the eggs, ward off predators, and usually die later in ...
