I just noticed a light brown growth with white dots on the bottom of my dock and some stray submersed tree branches. It's pretty gelatinous. I'm thinking it's some fish egg deposit but I can't find any information on it. Anyone have any ideas?

frog eggs!

i've pulled up many branches off my brush piles an had the same thing attached. i think its some kinda underwater mushroom. not any kinda eggs. just a fungus amungus FD

i would say frog eggs if it is round, ball shapped, jelly looking stuff. later you can see the individual cells with a small dot in each. i have pulled up sticks with the gunk fd said, it usually is smaller without much form. that gunk, i have no idea what it is. but i am sure the other is frog eggs.

when i was a kid, we would throw those frog eggs at each other poor frogs

UMMMM, FELLAS? DON'T FROG'S COME FROM TAD POLES? i BELEIVE THOSE JELLY EGGS ARE CATFISH EGGS. DON'T YOU THINK? HAVE A GREAT DAY!!

Not unless catfish live in every mudhole in the woods. Yes tadpoles come from frog eggs.

I was always told they were shad eggs.

This ?? came up last year by waterman and I told him to run run its the Blob but no one believed me,ol well I tried. As fishdoc said it is not fish eggs or frog eggs was the final outcome posted. A fungus of some sort.

I was curious, so I looked around and I found this on a TVA newsletter: The answer is “bryozoans,”
According to TVA staff members,
who frequently receive such
inquiries from reservoir users, it
usually goes something like,
“What’s that big glob of slimy
stuff stuck under my dock?” or
“What’s that jelly-like blob I saw
attached to some twigs under
the water?”
Bryozoans are tiny, harmless
aquatic animals. They don’t bite
or sting. The gelatinous, oftentranslucent
mass sometimes
spotted in TVA reservoirs is the
external skeleton of a bryozoan
colony. Sort of like hornets attach
their nests to tree branches,
bryozoans attach themselves to
whatever is handy underwater to
build their colony. Colonies can
range from the size of a marble
with a few dozen inhabitants up
to a mass the size of a honeydew
melon that contains many
thousand individuals.
If you spot a bryozoan colony
clinging to your dock, don’t
remove it. These little-known
and harmless creatures are an
important part of the Valley’s
diverse aquatic ecosystem.
