A golden shiner observed in the Mullica River, New Jersey. Though it has been known to reach lengths of 30 cm (12 in), in the wild the golden shiner is usually between 7.5 and 12.5 cm (3.0 and 4.9 in) long. The body is laterally compressed (deep-bodied). The back is dark green or olive, and the belly is a silvery white.
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 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 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 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.
Hornyhead chubs spawn from May through June. They become sexually mature at 2 to 3 years of age. Males build a cup shaped depression that they build up with pebbles that can be as large as 1–3 feet (0.30–0.91 m) across and 6–8 inches (150–200 mm) high. [3] Eggs and sperm are deposited in depressions in the nests and covered with gravel.
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 ]
