Leopard and shovelnose sharks are providing most of the action at the beaches, at least for those looking for serious tugging.  Sardines, anchovies, mackerel chunks and squid are all good baits, but the "pros" swear by small live croaker.  The biggest shark taken recently was a 100+ pound monster caught at Cardiff by Charles Masden of Vista.  Yup, he was using a live croaker as bait.  Agua Hedionda Lagoon in Carlsbad is a good place to be for spotfin croaker right now.  Best baits are mussel and bloodworms.
