Giant Sea Bass Fishing Tips

The giant sea bass used to be a popular game fish, but since its numbers declined, it is not allowed to keep the fish in California, USA. Occasionally, anglers would accidentally catch a giant black sea bass but they release the fish as soon as possible. You would need to go to Baja California, Mexico to legally catch this fish. Anglers who are going for 30-50 feet deep waters in a steady drift of a boat are the ones who often get a catch of this powerful fish.

There are not many records of the giant sea bass since it is protected, but with a fish that can grow more than 500 lbs. You would have to think of using a piece of equipment specifically for an enormous fish, like the Goliath Grouper. Here are the gears used for a goliath grouper which is also suitable for the giant sea bass. You would need a heavy 7’6 feet spinner rod with a strength of 90 lbs drag and a 400 lbs+ monofilament line. They have an enormous powerful mouth, so use a large hook 20/0 to handle their power. For baits, use large pieces of fish, squids, or crabs attached to lead head jigs or a feather tail. Like the goliath grouper, they’re not shy to take a bite.
