I bet you will want to sink the cages as deep in the mud as you can get them, if the purpose is to keep crayfish out.
Wife went to a lot of trouble planting water plants in an aquarium that we were keeping some green sunfish and crawdads for the kids to watch when they were little. Crawdads excavated all the dirt and plants and generally made a mess of all of her work.
They are very industrious little critters. I would bet they would easily burrow an inch or two deep to get under a cage to get at a tasty plant they desired. Not to mention all the baby crayfish that will be able to go through the mesh of the cage and grow up on the new plants.
No experience caging plants here. Just what I can imagine happening.
