Heat a large nonstick skillet over medium-high heat. Coat the catfish lightly with oil, and season with salt and pepper. Pan sear the fillets for 3 minutes per side. Remove fish, and set aside.
Reduce heat to medium low. Add pesto sauce, and cook for 1 minute. Add cream, and bring to a simmer. Add cooked pasta and catfish to sauce.
Serve, and garnish with fresh basil.
