use small jigs and catch bait at the rigs
Best answer! And it's free.
Size 10 or 12 Sabiki with the gold hooks. Just tie on and add a 3 or 4 oz. torpedo sinker. Drop to depth that they are holding and put in gear. Pump the rod up and down. When you feel one on, start reeling slowly. You'll load up all 4 or 5 hooks that way, and fill your tank quick.
The best bait is the bait that's actually out there, not the stuff in the fridge at the local tackle store on land.
