The record for cobia is 135 lbs. Most cobia are 25 to 60 lbs. Beware when angling for cobia, they are tough attacking and also are dangerous. Sometimes they are misinterpreted for sharks. They have a reduced mouth that protrudes past the top jaw with dark skin that varies from light bulb to tan. Their body is lengthy and also slim with a yellow-white underside.
If fishing from shore or a pier use sand worms, tiny crabs or strips of squid or clams while utilizing a 20 pound leader. You could have a great deal of fun capturing them as they argued. Once again they are a bunch of fun to capture. Best of luck angling!!
