If you clean your tools when you're done with them it may help. You could probably wipe them down with vegetable oil after cleaning them to prevent corrosion.
I've never done this but vegetable oil is non toxic so I don't see any reason why the fish would be affected.
I used to work for a tree service that ran vegetable oil instead of bar oil in the chainsaws to keep from contaminating plants and animals.
