Semotilus atromaculatus

Semotilus atromaculatus, known as the creek chub or the common creek chub, is a small minnow, a freshwater fish found in the eastern US and Canada. Differing in size and color depending on origin of development, the creek chub can usually be defined by a dark brown body with a white lateral line spanning horizontally across the body. It lives primarily within streams and rivers. Creek Chubs attain lengths of 2-6 inches with larger specimens of up to 12 inches possible. The genus name Semotilus derives from the Greek word sema (also known as dorsal fin), and atromaculatus comes from the Latin word "black spots".

Rhinichthys atratulus

Eastern blacknose dace (Rhinichthys atratulus) is a species of ray-finned fish in the genus Rhinichthys. It is dark brown to olive on its dorsal surface and silvery white below, the two shades separated by the darkly pigmented lateral line. In the breeding season, males develop darker pigmentation and an orange lateral line. Blacknose dace live in streams and rivers across eastern N.A, where they feed upon small invertebrates and microscopic biological matter. They may provide forage for larger fish. The western blacknose dace (Rhinichthys obtusus) formerly was considered conspecific.

Rhinichthys cataractae

The longnose dace (Rhinichthys cataractae) is a freshwater minnow native to North America. Rhinicthys means snout fish (reference to the long snout) and catarace means of the cataract (first taken from Niagara Falls). Longnose dace are small, typically less than 100 mm and characterized by their fleshy snout that protrudes past the mouth. They are well adapted for living on the bottom of fast-flowing streams among stones. Longnose dace eat algae and aquatic insects and are important forage minnows for larger predatory fish.

Luxilus cornutus

The common shiner (Luxilus cornutus) is a freshwater fish of the Cyprinidae family, found in North America. It ranges in length between 4 and 6 inches, although they can reach lengths of up to 8 inches.

Description 

The common shiner is silvery colored (sometimes bronze) and has an "olive back with a dark dorsal stripe." 

The common shiner is a freshwater fish that can be found in North America. Adults inhabit rocky pools in small to medium rivers. They can live to be approximately 6 years old.

Cyprinella spiloptera

The spotfin shiner (Cyprinella spiloptera) is a species of ray-finned fish in the family Cyprinidae. It is a small sized fresh water fish found abundantly in many watercourse of North America.

Taxonomy 

Edward Drinker Cope described the spotfin shiner in 1867, it is known also as the silver-finned minnow or the satin-finned minnow.

Notropis hudsonius

The spottail shiner or spottail minnow (Notropis hudsonius) is a small- to medium-sized freshwater minnow. It can be found as far north as the 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. One of the defining features of a spottail shiner is the black spot found at the base of the caudal fin. These shiners generally spawn from late June through July.

Notropis atherinoides

The emerald shiner (Notropis atherinoides) is one of hundreds of small, silvery, slender fish species known as shiners. The identifying characteristic of the emerald shiner is the silvery emerald color on its sides. It can grow to 3.5 inches in length and is found across North America from Canada to the Gulf of Mexico,

commonly in large, deep lakes and rivers, though sometimes in smaller bodies of water as well. It feeds on small organisms such as zooplankton and insects, congregating in large groups near the surface of the water. It is a quite common fish and is often used as a bait fish.

Etheostoma caeruleum

The rainbow darter (Etheostoma caeruleum) is a native North American fish found in small, fast-moving streams and small to medium-sized rivers. It grows to 2 to 3 inches (51 to 76 mm) in length.[1] The species is very sensitive to pollution and silt, staying in clean, pollution-free water. The rainbow darter is easily identified by three dark spots on the back, and blue and orange in the dorsal and anal fins. It is a small perch-like fish found in freshwater streams in North America.

Campostoma anomalum

The central stoneroller (Campostoma anomalum) is a fish in the family Cyprinidae endemic to the United States.

Distribution 

The central stoneroller is widespread in freshwater streams throughout a large portion of the eastern, central, and midwestern United States. It is present in the Atlantic Ocean, Great Lakes, Mississippi River, and Hudson Bay basins in the US, from New York west to North Dakota and Wyoming and south to South Carolina and Texas.

Neogobius melanostomus

The round goby (Neogobius melanostomus) is a euryhaline bottom-dwelling goby of the family Gobiidae, native to central Eurasia including the Black Sea and the Caspian Sea. Round gobies have established large non-native populations in the Baltic Sea, several major Eurasian rivers, and the North American Great Lakes.

Characteristics 

Round gobies are small, soft-bodied fish, characterized by a distinctive black spot on the first dorsal fin. Their eyes are large and protrude slightly from the top of the head and,

Pomoxis annularis

The white crappie (Pomoxis annularis) is a freshwater fish found in North America, one of the two crappies. Former common names include goldring and silver perch.[2] The USS Goldring is named for the fish.

Description 

White crappies are very similar in appearance to black crappies. They have 5–10 vertical bars along their body, rather than the randomly scattered spots like the black crappie. It has a silvery color with green or brown shades along its back, with dark lateral bars along its side and a white belly. The dorsal fin of the white crappie starts further back on the body than that of the black crappie. White crappies are also slightly
