I have something on my trees as well that look like egg ribbons?? But I know I don't have any perch? Could it be some other type of fish other than perch???? Do you have a picture of what they look like? Mine were at the tips of the branches and white in color all in strands of about 8 to 10 inches.
Perch ribbons are several feet long and look like wet toilet paper in the pond. Also its doubtful you have perch ribbons because they would have spawned in Arkansas over a month ago.
If your ribbons are black they are probably toad egg ribbons, they would be everywhere by now down there
