I think you have a couple of options. One of tried was already mentioned, using some sort of rack on top of a cookie sheet or baking pan.
What I do most often that seems to work well is to use parchment paper on a cookie sheet. It requires no oil at all (although I'll usually spray them with a bit of Pam) and it keeps my fish dry and crispy.
Also, if you can find something frozen and healthy where you live, I do better with the pre-breaded stuff than when I make my own. I can buy this very healthy breaded haddock that is dense and crispy and delicious. When I bread it myself it never comes out as well.
Hope this helps.
