Minnows -spawnning question

[DangrsDaveO]

I am sure someone out here know the answer to this question. How often do minnows like shiners, fatheads, crappie minnows spawn during the course of a year? My son and I were talking about this and thought the internet could answer the question but so far no luck. I know game fish spawn once a year and I think that is the answer for minnows but need to be sure. Thanks in advance. Good luck fishing!

According to what I found, shiners spawn once/year and fatheads can spawn as many as 10 times/year.
