Preheat the oven to 375°F (190°C).
In a large bowl, mix together the crab meat, diced shrimp, cream cheese, parsley, garlic powder, lemon juice, salt, and pepper.
Using a sharp knife, make a lengthwise slit in each salmon fillet, creating a pocket for the stuffing.
Stuff each salmon fillet with the crab and shrimp mixture, pressing it gently to secure the filling.
Place the stuffed salmon fillets in a greased baking dish and drizzle with olive oil.
Sprinkle breadcrumbs over the top of each stuffed fillet for added texture.
Bake in the preheated oven for 20-25 minutes, or until the salmon flakes easily with a fork.
Remove from the oven and let it rest for a few minutes before serving.
