The blacktail shiner (Cyprinella venusta), also called shiner minnow is freshwater fish species with a slender body of the family Cyprinidae and subfamily Pogonichthyinae. The genus Cyprinella is called satin fin shiners and consists of carps and minnows. The fishes of this genus are native species to North America and the southern United states.
Cyprinella is a Greek word meaning 'small carp,' and the specific term venusta is Latin which, means 'beautiful, like venus.' Numerous Cyprinella species are listed as Threatened.
There are currently around 32 described species in this genus. The blacktail shiners do not face population decline but, they face the threat of habitat destruction. These fishes have yellowish-olive backs and silvery sides.
There are three recognized subspecies of Cyprinella venusta, C. v. stigmature, C. v. venusta, and C. v. cercostigma. The primary diet of the blacktail shiners is invertebrates.
The members of the subfamily Pogonichthyinae are called North American clade minnows or American minnows. There are six subfamilies under Cyprinidae. In Illinois and texas, the black shiners hybridize with red shiners (C. lutrensis).

Two subspecies are found in Alabama. C. v. stigmature or slender Blacktail shiner is found in the upper mobile river basin and C. v. cercostigma or the eastern Blacktail shiner is found in the lower mobile river basin and coastal rivers.
What is a blacktail shiner's habitat?
The blacktail shiner (Cyprinella venusta) is commonly found in sandy runs, pools, small-medium-sized rivers in regions with strong water currents and sparse vegetation. However, the upland population occupies creeks over the substrates with rubble, silt, bedrock, and gravel.
The western population occupies the turbid waters. They were most abundantly found in swift runs in summer and spring in Blanco River, Texas. In village creek, texas, they were found throughout the year in sandbank and riffle habitats
Who does blacktail shiner live with?
Cyprinella venusta lives in schools.
How long does a blacktail shiner live?
Cyprinella venusta lives up to four years of age in the Leaf river system, Mississippi, and up to five years of age in Blanco River, Texas.
How do they reproduce?
The spawning of these shiners is from April to September in Texas. Spawning is from late March to early October in Mississippi and most females are reproductive from April through September.
Some of these shiners found in Village creek in Texas had size distribution persistent with protracted spawning season. Fractional crevices are the spawning habitat situated in flowing water.
The blacktail shiners in Blanco River, Texas were observed to be depositing their eggs under large cobble and small boulders in bedrock riffles in high water velocities. Males are responsive to the spawning female's sounds and can easily differentiate these sounds from the red shiner females'.
The meals defend these crevices with eggs from other males. The eggs are usually deposited with viable sperm by the females.
Right after spawning, the male eats any eggs that would not make it into the crevice. Both small and large males enter the crevices of other males to deposit sperm before the start of courtship.
The female blacktail shiners had 340 ova and 139-459 ova found in the Blanco River, Texas and southwest Mississippi. In the Pearl River, Mississippi, the females laid 20-46 clutches in the reproductive season.
What is their conservation status?
The conservation status of the blacktail shiner fish is Least Concern. However, they face threats from habitat changes due to irrigation, flood control projects, drilling, mining, grazing, and hybridization.
