Heat olive oil in a skillet over medium heat. Add seafood mix, salt, black pepper, and parsley. Sauté for about 3 minutes until seafood is just cooked through, then remove from heat.

Spread a thin layer of béchamel sauce on the bottom of the greased baking dish. Arrange a layer of lasagna noodles over the sauce. Top with one-third of ricotta mixture, followed by one-third of the seafood, and one-third of remaining béchamel sauce. Repeat to form three complete layers, finishing with remaining noodles, béchamel sauce, and top with shredded mozzarella.
