They are called redtailed surfperch, some people call them pink finned surf perch, never heard them called red fins? But I know what you mean. :lol:
The peak redtail fishing is probably over for the summer but you can still get them around rock structure, jettys, bridge pilings or especially anywhere where the tide creates sandbars and riptides or back eddies.
You might fish near the oyster farm, if there aren't any surfperch you have a decent chance at some kelp greenling or black rockfish.
Some redtails from this spring.
