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.

The only difference between a rut and a Grave is the depth. So get up get out of that rut and get moving!! Time to work!!
