Preheat oven to 350°F (180°C).
Combine the salt and the eggs.
Cover the largest baking sheet you have with aluminum foil. Place a layer of the salt-egg mix onto the baking sheet where the fish will lay.
Place the fish on top.
Fill the cavity of the fish with the lemon and herbs.
Cover the fish with the rest of the salt to form a crust. The head and tail will stick out from under the salt blanket.
Cook for 45 minutes.
Remove from the oven.
Remove the crust, discard the lemons and herbs and serve the fish.
