Types of minnows

Bluntnose minnow :''"Bluntnose minnows" is also used for the genus ''Pimephales'' as a whole.'' The bluntnose minnow (''Pimephales notatus)'' is a species of temperate freshwater fish belonging to the genus ''Pimephales'' of the cyprinid family. Its natural geogra ...

(''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 ''Pimephales'', commonly known as the bluntnose minnows (a term used locally to refer to ''Pimephales notatus'' specifically), is a genus of cyprinid fish found in North America. All of the four species are small fish, with ''P. notatus'' being t ...

As food

While primarily used for bait, minnows can also be eaten directly by humans. Some Native American cultures have used minnows as food. If minnows are small enough, they can be eaten whole.

Threats and conservation issues

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. Minnows are also flexible in attaining pre-spawning fitness, which makes them avoid 'skipped spawning' decisions while facing climatic variabilities.
