Asian-Style Whole Fish En Papillote/ Parchment-Cooking
Fitting whole fish such as trout, sea bass in the wok-steamer has always been a problem. The wok-steamer method tends to work better for smaller-size fish (e.g. Pickled Chili Steamed Tilapia, Steamed Rockfish), so bigger fish finds its way in En-Papillote/ Parchment Cooking (see Herb-Roasted Whole Trout En-Papillote) - which is also one of the easiest methods (one of my favorite ways) to prep and cook fish (whole or fillets).

The entire fish can be roasted in the oven without enclosing in parchment packet; however, if the intention is to enjoy moist, succulent, tender steamed fish with some gravy and sauce; en-papillote or cooking in enclosed parchment packet might be the closest as it gets to steaming in a wok/pot over the stove.
