Rented a cottage last week on a small lake in the Minden area.
When fishing off the dock noticed that some weeds I had snagged had a gelitan like clear slime encasing the stalk.
Anyone seen this before, know what causes it and if it is harmful to the lake.
No algea in the lake, it is 60 ft deep for a small lake and very healthy small bass population.
It was not isolated to one spot but found this throughout the lake.

Few other photo's:



It was mentioned on another forum that they are Fresh Water Jellyfish.
After doing some research fresh water Jellyfish are refered to as "Craspedacusta Sowerbyi."
I dont think what you see in the photo are fresh water jellyfish. This is almost like an algae that has compassed some of the weed structure.
They do seem to be common in Ontario, but are creature that are like salt water Jellyfish.
