The Rio Grande Silvery Minnow belongs to the Cyprinidae family. The maximum size of the Rio Grande Silvery Minnow is 8.9 cm. It has a life span of about 25 months. It spawns in the spring. It is an endangered species that cannot be caught.
It is a small fish with a small mouth. The brown to olive dorsal region with a wide and dark medio-dorsal stripe; silvery lateral region with dark pigmentation forming a diffuse medio-lateral band; white ventral region.
The Rio Grande Silvery Minnow lifestyle
The Rio Grande Silvery Minnow are herbivores whose diet would be composed of river plants and benthic macro-inverters, although little research has been conducted on their diet due to the difficulty of entering their stomachs. They play a role in keeping the water clean by eating bad algae. They are used as a food source for other animals.
The Rio Grande Silvery Minnow are pelagic spawners. Reproduction normally consists of several spawning episodes with an interval of about 10 minutes between spawning sessions. Spawning behavior includes male silver minnows chasing a single female. If a female minnow is ready to reproduce, a single man will move his abdominal area and then wrap himself around the female. Usually, at about this time, eggs and milt are extruded simultaneously by the male and female minnows. The Rio Grande Silvery Minnow eggs hatch within 24 hours of fertilization. The Rio Grande Silvery Minnow larvae can start swimming three to four days after hatching.
The Rio Grande Silvery Minnow habitat
The Rio Grande Silvery Minnow prefers large streams with a slow to moderate flow over mud, gravel or shifting sandy substrate. Silver minnows generally occupy streams where the water depth is moderate from 0.2 to 0.8 m (8 in. to 31.5 in.) and their speed varies from 0 to 30 cm (0 to 1 ft / s). In winter, these minnows are most often found in almost always calm waters covered with debris. However, at low flows, they are found in isolated pools and in watered sections immediately downstream of diversion structures. The Rio Grande Silvery Minnow have also been found in ditches and irrigation canals.
The Rio Grande Silvery Minnow were once abundant in the Rio Grande and Pecos basins, but are now limited to a few sites in Rio Grande, New Mexico. In North America, the Rio Grande Silvery Minnow lives in the Rio Grande River. The Rio Grande Silvery Minnow currently occupies less than 10% of its historical range. It is now found only in the Rio Grande River from Cochiti Pueblo, downstream of the Elephant Butte Reservoir watercourse. Apparently, this species is now extinct in Texas.
