What kind of eggs are these?

[poconojoe]

Appear to be egg sacs. Never seen these before. I've see clear eggs attacked to things in the past, but never sacs like these. At first sight I thought they were waterlogged earthworms. We have 1500 gallon pond with koi, goldfish, comets, and shubunkin.
Thanks,
Joe

Some sort of American Aquatic snail perhaps ?
That would be my best bet .....

So, you think they are snail eggs? I have a lot of trapdoor snails in there.

Trapdoors are live bearers (ie, no eggs). Sorry I can't be of much help other than this page I found via google (http://bugguide.net/node/view/479353/bgimage). Not an exact match, but maybe some type of insect?

My problem is I inreality only know british bugs snails etc so I'm not up on yours but my best other bet would be something like the mayfly

I don't know. They more resemble what I've seen when fishing and found them inside fish when gutting them. Sort of sacs with eggs inside. When fish lay eggs, don't the eggs come out individually? Do whole egg sacs ever come out?

Certainly a few of my female fish are looking quite full. Down right chubby! And in the early spring they were being chased down relentlessly as usual. Iv'e seen eggs before, but not these sacs.
Oh, and thanks for the responses everyone.
