Types of minnows
Bluntnose minnow (Pimephales notatus): The bluntnose minnow is a primary bait fish for Northern America, and has a very high tolerance for variable water qualities, which helps its distribution throughout many regions. The snout of the bluntnose minnow overhangs the mouth, giving it the bluntnose. There is a dark lateral line which stretches from the opercle to the base of the tail, where a large black spot is located. The average size of the adult is approximately 5 cm (2 in). 'Pimephales
Common shiner Notropis cornutus: These fish are one of the most common type of bait fish and are almost exclusively stream dwellers. The common shiner can be identified by the nine rays on its anal fin and terminal mouth. This minnow is typically bluish silver on the sides and greenish blue on the back., save for breeding season in which case the male gains a rose colored tail and anal fin. The shiner grows about 5–10 cm (2–4 in) within one year and reach a size of 13 cm (5 in) at adulthood. Another common "shiner" bait fish is the young version of the European chub (Leuciscus cephalus or Squalius cephaloides) which is quite easy to catch. Notropis potteri is known as the chub shiner.
Common emerald shiner (Notropis atherinoides atherinoides): Common shiners are most abundant in the Great Lakes of North America, primarily Lake Erie. The name of the emerald shiner comes from the greenish emerald band that expands from the back of the gill cover to the tail. This type of minnow has a short, rounded snout, the only difference between the common emerald shiner and the silver shiner is that the silver shiner has a longer snout and a larger eye. These fish grow to an average length of about 6 cm. This is one of the most common bait fish used in the Lake Erie region of Ohio and many fisherman hold it over all other bait.
Topminnow (Poeciliopsis occidentalis occidentalis): An endangered minnow species which are found primarily in southern New Mexico and Arizona. The drop in the topminnow population can be linked to the introduction of the common mosquitofish. This type of minnow grows to a length of 6 cm (2+1⁄2 in) with the females growing to be larger than the males. During times of breeding males turn black while females and non-breeding males are tan or olive-green. The diet of the topminnow consists of bottom debris, vegetation, and small crustaceans.
Common mosquitofish (Gambusia affinis): The mosquitofish is a very small minnow which has received its name for its fondness for mosquito larvae. The mosquitofish usually reaches a length of only 2.5–5 cm (1–2 in) long. This is a peculiar fish because the male has a "modified" anal fin and female gives birth to live young, much like their related cousins the guppy.

Threats and conservation issues
Minnows are more reproductively resilient than anticipated.[by whom?] Generally, minnows breed with the slightest rainfall and within a wide temperature range. Contrary to the long-standing presumptions, climate change poses 'negligible' threat to minnows' reproduction. Also, they are flexible in attaining pre-spawning fitness, which makes them avoid 'skipped spawning' decisions while facing climatic variabilities.
