1. In a large pot, heat the olive oil. Add the shallots, leeks, fennel and garlic and cook over moderate heat until softened, about 8 minutes. Add the saffron and cook, stirring, for 1 minute. Add the tomatoes and tomato paste and cook over moderately high heat, stirring, for 2 minutes. Add the fish bones and heads, 3 quarts of water, the thyme, parsley and bay leaves and bring to a boil. Simmer over moderately low heat for 45 minutes.
2. Strain the broth and discard the solids. Return the broth to the pot and boil over high heat until it is reduced to 6 cups, about 20 minutes. Season the broth with salt and pepper.
3. In a small saucepan of boiling, salted water, cook the potato until tender, about 7 minutes. Drain well and transfer to a food processor. With the machine on, add the egg yolks, chopped garlic, red pepper and harissa and process to a puree. With the machine on, add the olive oil and process very briefly until it's just incorporated. Scrape the rouille into a bowl and season with salt. Cover and refrigerate.
4. In a large pot, heat the olive oil. Add the garlic, leek and fennel and cook over moderately low heat, stirring occasionally, until tender, about 8 minutes. Add the potato and cook until just tender, about 5 minutes. Add the tomato and cook, stirring, for 3 minutes. Stir in the broth and bring to a boil. Add the clams and cook over moderate heat until they start to open. Add the mussels, shrimp and fish and simmer until all of the seafood is just cooked, about 4 minutes. Stir in the lemon juice and basil; season with salt and pepper.
5. Spread the baguette toasts with some of the rouille. Spoon the bouillabaisse into 4 large, shallow bowls and serve with the toasts and lemon wedges. Pass the remaining rouille at the table.
