There are plenty of bigger Black Seabass out there. They are typically caught near shore at Catalina while fishing white seabass close to the beach. The guys on the Phantom said they have been in wide open 50-200 lb. fish for up to 2 hours! The one you caught was still a youngster. These fish live for 75-100 years and can get up to 500 lbs. or more. They will eat just about any other fish that will fit in there mouth like calico bass, barracuda, bonita, mackeral, yellowtail and rockfish. Make sure you guys release these fish in good condition! Dont think the 15# line will make much of a difference if you get a big boy. Good luck and tight lines.
