Scup are bottom feeders and tend to stay close to the ocean floor. They are known to school in large groups and are often found near rocky areas or jetties. Scup are opportunistic feeders and will eat a variety of small fish, crustaceans, and mollusks. They are also attracted to the scent of fresh bait and will often follow it to the hook. Scup are active during the day and tend to be less active at night.
