I was also going to say to chum spearing. Blues will be less of hassle, but cost can be prob unless you seine yourself. bunker chum may bring other species, as well.
Bait with spearing, butterfish chunks.... or killi fish. SMALL HOOKS and don't overdo it on the line.
swivel with fluoro leader optimal.
Have a rod with small diamond jig, no tail ready. Drop into slick and speed retrieve.
