They kinda almost disappear after they spawn as most of the adults die off and all you're left with a small juveniles which are hard to catch in nets as they slip through the holes and very tiny larvae.
Most of my adults disappear after spring spawn, so that tells me their lifespan is basically one year. I can still find a few adults after spring spawn, so I suppose they are the ones that will spawn late. It's almost as though there are 2 sub-sub species, both with a lifespan of 1 year. The literature says lifespan is up to 2 years, but that doesn't sound right. Seems like 2 year survivors would quickly dominate and the 1 year type genetically, and they would soon disappear. Any thoughts on that?
