Cobia are often targeted at night from late spring through the summer off of bridges and piers. The key is to fish the bridges and piers that have good lighting. Even though, you can catch cobia at night in these spots, these fish are not nearly as abundant as some of the other fish that are caught from these spots. Most of the boaters like to target cobia during the day because the fishermen usually sight fish for them. Most of these anglers do not target cobia at night. If you can find the fish, they can be caught as they feed throughout the night.
