The unofficial guide to craspedacusta sowerbii/freshwater jellyfish

  • We are currently upgrading MFK. thanks! -neo
Don't they mainly reproduce a-sexually though? That's what the OP/freshwaterjellyfish states

If I ever did acquire one, it would be placed in a tank along with dirt collected from the same pond to hopefully establish a colony.

Yes, but the medusae can only reproduce sexually, which sounds like an impossibility, the thing you want are the polyps, as they can reproduce asexually. The polyps look like mini anemones.
 
Agree with j. H. On it being very rare for the medusa to breed. The majority of populations are usually just one sex.
 
to your knowledge, has there been any research into water temperature leading to medusas?

the sighting at Folsom Lake, happened the same year it made national news for being empty. It was also very warm ( I was still swimming in it without a wetsuit in October of that year). The other sightings seem to generally be at shallow ponds that warm up past 25c

Interesting the only one I've seen was during a very hot summer,water was in the 90s in the shallow near shore areas,the jellyfish was snagged accidentally in less than a foot of water and was about two inches wide, after handling and releasing I felt a slight tingling in my fingers after a few minutes.
