The minnow lives throughout Ontario and the Northeastern United States. [5] In the state of Ohio, the minnow is only confirmed to inhabit the Great Miami and Little Miami rivers. [2] The Ohio population of Exoglossum laurae, which is separated from more Eastern populations by several hundred miles, is considered a subspecies. [2]
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 ...
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 Olympic mudminnow is listed as a sensitive species by the state of Washington. Although many populations are found, the range is limited, and suitable habitat is easily lost to development. [3] [4] [5] Spawning occurs after overwintering with a short photoperiod and temperatures under 40 degrees Fahrenheit.
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.
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.
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.
The Topeka shiner lives mainly in prairie streams. In order for the Topeka shiner to survive the water must be cold and clear. The streams in which this Minnow lives are typically consistent and run year long. In cases in which the stream does dry up, the Topeka Shiner needs to find a new stream or permanent body of water to survive.
