Fish are jumping...

Via Light Reading:

Dr. Sulak said, the jumping must not be for reproductive reasons. And since they have no freshwater predators but occasional alligators, it is probably not an escape response.

Might they jump for joy?

Doubtful, Dr. Sulak said.

His guess is that sturgeon jump to let other sturgeon know they have found a good spot to hang out. They seem to gather mainly within six short, narrow stretches of the Suwannee where there are deep holes, so they do not have to waste energy fighting the current. They fast and relax all summer, basically “just going to the spa for several months,” Dr. Sulak said.

They can use the rest....
