The Eurasian minnow, [2] minnow, [1] or common minnow (Phoxinus phoxinus) is a small species of freshwater fish in the carp family Cyprinidae. It is the type species of genus Phoxinus . It is ubiquitous throughout much of Eurasia , from Britain and Spain to eastern Siberia , predominantly in cool (12–20 °C (54–68 °F)) streams and well ...
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.
Spawning season for the blackspotted topminnow stretches from March to early September, with peak spawning occurring in May. [8] On occasion, large males have been observed keeping an open territory of three square meters, Males seldom tolerate females in the wild, except during morning or evening spawning activities.
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.
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 spottail shiner or spottail minnow (Notropis hudsonius) is a small- to medium-sized freshwater minnow. It can be found as far north as Canada and as far south as the Chattahoochee River in Georgia. These shiners live in lakes, rivers, and creeks. They occupy the rocky or sandy shorelines and bottoms of the water.
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.
The wide range of spawning time is believed to be due to water temperature. Thus, plains topminnow spawning times usually depend on the latitude of individual populations. [ 8 ] The plains topminnow breeding season was observed at 60 days in Missouri and Nebraska, regardless of latitude and water temperature. [ 4 ]
