Description

The common shiner is silvery colored (sometimes bronze) and has an "olive back with a dark dorsal stripe." [3]

The common shiner is a freshwater fish found in North America. Adults inhabit rocky pools in small to medium rivers. They can live to be approximately 6 years old.[4]

They are considered sexually mature by 7.4 cm. Breeding males have a pinkish tint over most of their body and small bumps or tubercles on their head.[5]

In comparison with Notropis, the common shiner's head, eyes, and mouth are large.[2]

Life History

The common shiner can be found in cool clear creeks and small to medium rivers, usually in the faster pools near riffles and in the shallow littoral of ponds and lakes.[3] Its preferred water temperature is 21.9 °C.

The common shiner reaches sexual maturity by 1–2 years of age, and produces between 400 and 4000 eggs per year. Common shiners spawn in spring between May and June, at temperatures of 16-26 °C. Common shiners often spawn over the nest of a creek chub, river chub, or fallfish, although some males will make their own small nests. Gravel in riffles is also possible.[2] Once the eggs are ready the male guards the nesting site.[3]

Common shiners are known to hybridize with other shiner species.[2]

Common shiners live for about 5–7 years.

Diet

The common shiner eats "terrestrial and aquatic insects, vegetation, and other fishes." [3]

Predators

Predators of the common shiner include fish (such as the smallmouth bass and chain pickerel) and birds (i.e. mergansers and kingfishers). [3]

gollark: Well, you should fear them *too*, but guns are obviously quite rare here.
gollark: Fear the person who practices a reasonable assortment of kicks and other strikes a large amount of times each, but also in integrated practice and live sparring?
gollark: Also, they *mostly* produce electron beams, the X-rays are IIRC a byproduct.
gollark: > you should remove the electron gun from your CRT displayimplying I have a CRT display?
gollark: I'm sure much of the knowledge transfers between them, and there are diminishing returns.
