Pre-heat oven to 350°F (180°C). Lightly brush a baking sheet with one tablespoon of olive oil.
In a medium bowl soak the potatoes in cold water for approximately 15-20 minutes, then rinse, drain well and towel dry.
Place the potatoes a medium bowl and toss with approximately 2 tablespoons olive oil and half the oregano, salt, parsley, rosemary and all the garlic.
Place the fish filets on the prepared baking sheet, sprinkle with salt, the remaining oregano, parsley and rosemary. Place the potatoes on the baking sheet with the fish, sprinkle with a little extra salt, oregano and olive oil if needed.
Bake for approximately 30 minutes. (I raised the temperature to 425°F (225°C) for the last 5 minutes to brown a little more the potatoes. Serve Immediately. Enjoy!
