1. **Prep the Ingredients:**
  - Dice the onion, mince the garlic, thinly slice the fennel bulb, and dice the bell pepper on the cutting board using the knife.
  - Cut the fish into chunks, and clean the shellfish.

2. **Sauté the Aromatics:**
  - Heat the skillet over medium heat and add the olive oil.
  - Sauté the diced onion, garlic, fennel, and bell pepper with a wooden spoon or spatula until softened, about 5-7 minutes.

3. **Combine in the Slow Cooker:**
  - Transfer the sautéed vegetables to the slow cooker.
  - Add the diced tomatoes (with their juice), seafood or fish stock, white wine, saffron threads, smoked paprika, thyme, basil, bay leaf, salt, and pepper.
  - Stir to combine using the wooden spoon or spatula.

4. **Cook:**
  - Cover and cook on low for 6-8 hours or on high for 3-4 hours, until the flavors have melded together.

5. **Add the Seafood:**
  - About 30 minutes before serving, add the chunks of white fish, shellfish, and shrimp to the slow cooker.
  - Cover and cook on high until the seafood is just cooked through and the shellfish have opened (discard any that do not open).

6. **Serve:**
  - Use the ladle to transfer the bouillabaisse into bowls, making sure to get a good mix of seafood and broth.
  - Garnish with chopped fresh parsley.
  - Serve with lemon wedges on the side for squeezing over the top.
