I would think that the eggs would be tougher than the fish? They are pretty firm to the touch from the ones I have seen over the years stuck to drift wood, dock floats and such. Fry fragile...yes..eggs sticking to the outside and inter weavings of a mesh material like air condition screen and then placed directly into a 30 gallon trash can filled with lake water and then moved to the lake less than 15 minutes away..even add an areator...but don't think I would need it...why wouldn't that work?
