Generally speaking, the time for steaming fish in the microwave oven is about ten minutes. But it also depends on the size of the specific fish and the type of microwave oven. Fish weighing less than one catty usually takes less than ten minutes. If you are not sure about the time, you can stew it several times in a row.

Cooking fish in microwave oven is the key to fish tenderness. Be sure to cover it with plastic wrap! Otherwise it will turn into dried fish.
