Calico surfperch are demersal species and can be found in the surf zone off sandy beaches but also dwell around depths of up to 30 feet. They can also be found around pier pilings, jetties, and other sandy areas in shallow waters. Making them an easy fish to catch due to being able to catch them from the shore or pier.

Bait & Tackle
The best bait to use is live soft-shelled sand crabs, mussels, sea worms (bloodworms or pile worms), shrimp, and clams. The fresher the bait the better. If you prefer artificials you can easily target them with Berkley Gulp 2.5″ Sandworms or small curly-tail grubs in Motor Oil/Pumpkinseed colors. Use size 6-8 Baitholder hooks on a Carolina Rig/Dropper Loop Rig with about 1-2oz. of weight to keep it from drifting in strong current.
Use and Trade
Fished commercially and for sport on a minor scale.
Calico surfperch females are viviparpous, meaning they carry the developing of the young. Which are born alive unlike your conventional birth from eggs.
You can distinguish a Calico from a Redtail by its freckles on the sides without distinct bars.
