Introduction and Notropis
The Shiner is a common name used to define several North American small fish together. While, a common trait is that most of the fish in the species are silver they may differ. There is various genus of shiners. These minnows include.
Eastern Shiners – Genus Notropis
Finescale Shiners – Genus Lythrurus
Flagfin Shiners – Genus Pteronotropis
Golden Shiner – Genus Notemigonus crysoleucas
Highscale Shiners – Genus Luxilus
Redside Shiners – Genus Richardsonius
Satinfin Shiners – Genus Cyprinella
However, the list is large and thus, we will cover these in various separate articles. Therefore, let us begin with the Notropis or Eastern Shiners. Notropis is a genus of freshwater fish in the Cyprinidae family. The continents second largest genus.
Generally, members of the genus have eight dorsal rays and no barbels, except the Redeye Chub. While, the scales are not much taller than they are wide, but not diamond shaped. Further, the species has short intestines with one loop at the front.
Currently 88 recognized species exist in the genus. Several articles will follow with a break down of these. However, in this article let us look at.
Soto la Marina Shiner
The Soto la Marina Shiner (Notropis aguirrepequenoi) is a species of freshwater fish in the Cyprinidae family of carps and minnows. Further, belonging to the Notropis species of Shiners. A small silver fish with a black lateral line and a black keel.
Native to Mexico and generally occurs in the lower Rio Grande river. While, this species is extremely vulnerable. Inhabit pools and riffles of clear streams with moderate to rapid water movement. Generally, prefer sand, gravel or rocky substrates.
Occurs on the northern Atlantic slope drainage in Tamaulipas and Nuevo Leon in Mexico. While, they have an extremely small range their numbers continue to decline due to the area, extent and quality of habitat. Especially due to habitat degradation, destruction, modification and reduction in range. Tourism, mining and forestry activities impact the population sizes in the upper portion of the Soto la Marina River.
While, the San Fernando River has not been altered extensively in Tamaulipas, the damming of the two upstream areas in Nuevo Leon has impacted the flow regime of the river. Meanwhile, the lower Soto la Marina is subject to severe pollution due to agricultural runoff and human development. Therefore, placing stress on the populations in this region impacting the fish negatively. Currently there are laws and regulations to protect the Soto la Marina Shiner.
The Palezone Shiner (Notropis albizonatus) is a rare ray-finned fish in the Cyprinidae family. Native to certain areas of the United States including Alabama and Kentucky. However, occurred in Tennessee but now extirpated.
Generally, has a slender and cylindrical straw-colored body with dark margins on some the rear scales. Further, has a dark, silvery lateral stripe with a spot near the tail. While, a pale stripe runs above the dark lateral line. Therefore, giving the fish their name.
Generally, lives in flowing streams with clear water and sandy or rocky substrates. While, spawning occurs in late spring and summer. Most jeopardized fish in the United States and federally listed as an endangered species.
Moreover, degraded conditions have limited their habitat range. While, coal mining pollution and reservoir construction in Tennessee has led to their extirpation there.
The Whitemouth Shiner (Notropis alborus) is a freshwater fish in the Cyprinidae family. Native to the eastern United States occurring in the Piedmont states of Virginia, North Carolina and South Carolina.
