Lake Oroville Jellyfish?

I was kicking back and boating up at Lake Oroville this past weekend when something in the water happened to catch my eye. At first I just though it was just some misc. trash, or even worse, duck poop; but then I noticed that "it" was actually swimming. I then realized that it was a jellyfish, in fact there were hundreds of them. I'd never even heard of that before. Very cool. I even caught a couple to get a closer look at them. Trippy indeed...

Fresh water jellyfish surface at Bidwell Marina and Lake Oroville

Freshwater jellyfish in Lake Oroville? Yes, it's true. And, there are "countless," "scores," and even "millions" of them appearing, according to eye witness accounts.

Bidwell Marina Store Supervisor Tara Paul said from 5 p.m. to 8 p.m. Monday she witnessed "millions" of Jellyfish covering the surface of the water around the docks at the Bidwell Marina.

"They were floating right on the surface and are the size of a quarter," Tara said. "I was born and raised in Oroville, and two summers ago I would see maybe two or three jellyfish in late summer, but I've never seen as many as I have this year."
Brandon Adkins is a dock crew member who rents the boats and helps customers at the marina.

"Monday night at about 5 p.m. I saw hundreds and hundreds of jellyfish at the marina. They were everywhere and all around the slips where the boats park," Brandon said.

Norm Morgan has driven the shuttle based at Bidwell Marina for the past few years and has been fishing on Lake Oroville for 12 years.

Norm said he has seen a few jellyfish on the lake before, but has never seen the large concentrations that he has seen lately.

"I've also heard some people reporting sightings of jellyfish in the South Fork too," Norm said.

Lieutenant John Kuhn, a long-time fisherman on Lake Oroville, said he saw "countless" jellyfish at the Bidwell Marina. "I also saw jellyfish around a houseboat about two weekends ago on the lake at Bidwell Canyon."

This reporter ventured to the Bidwell Marina at about 2 p.m. on Tuesday and searched for the jellyfish, but only two were found.

"They seem to come out in more numbers after 5 p.m." Brandon said. "You might want to come back later and check again."

Mike Hubbartt of the California Department of Parks and Recreation at the Lake Oroville Visitor's Center is an interpreter on the historical and natural features of Lake Oroville.

Hubbartt confirmed the presence of the freshwater jellyfish on Lake Oroville and provided the following information to the Oroville Mercury-Register.

• Appearance of the jellyfish is "sporadic and unpredictable." Often jellyfish will appear in a body of water in large numbers even though they were never reported there before. The next year they may be absent and may not reappear until several years later. It is also possible for the jellyfish to appear once and never appear in that body of water again…

• Like true jellyfish, these freshwater jellyfish also have stinging cells called cnidocytes. This mechanism is designed for feeding, as the cnidocytes are utilized to paralyze macro invertebrates and even small fish. However, there is no "hard" evidence that these organisms can penetrate human skin (though some have claimed otherwise), according to an expert study on freshwater jellyfish.
 
In my continuing quest to be the most pedantic person that posts here...these are not actually jellyfish. They're hydroids. But still very cool! Thank you. :D
 
Hmm. Well, I guess I really should have been more specific. LOL. But they really do LOOK like jellyfish. They're about the size of a quarter, sort of a translucent whitish color, and swim in the pulsating manner normally associated with TRUE jellyfish. I guess there's a lot of them this time of year, when the water's a bit warmer than usual. Weird how they seem to congregate around the marinas though. Why would that be?
 
perhaps a great food source around those areas?

cool info. Thanks for the links. I enjoyed the new reel about them.
 
reminds me of that landlocked body of saltwater in the phillipines or thailand? where there's ridiculous amounts of photosynthetic jellyfish...
 
Back in my home town Groveland one of the local lakes (Pine Mountain Lake) has them as well. I did some research on them a while back and found that they live here and there in the lakes of the sierra nevadas. It's kinda rare to see them usually. In my experience they do not sting, but you know how peoples imaginations run wild. Many people said they had been stung, but I kinda doubt it being that I have held like 12 of them and never felt any sort of sting.
 
The next craze should be freshwater jellies. I've seen the coldwater sea version. This should be a hit if you don't have to refrigerate your tank.
