Most of the efforts seem to be concentrated in the south bay region - below the
Coronado bridge. Some folks target them; most are caught as "by-catch." A
smallish fish. Croakers, halibut, and several types of bass are much more
plentiful. And, IMHO, more fun to catch!
At a "minus" low tide, it is possible to wade along the Coronado side. Lots of grass beds,
so a floating line works best (for me.) Sinking lines are fine from a boat. Although not for me, I see guys around the bridge in float tubes.
Good luck,
