This is a recipe that appeared on a card at my local ShopRite, and the card states it comes from a magazine named Simply Seafood. It works best with an Asian bamboo steamer or equivalent. The card states the recipe is also delicious with trout, rockfish, and small striped bass. I haven't tried these fishes in this dish. According to the recipe, a whole tilapia is prepared, but filets can definitely be adapted!
