Tuna Fishing Tips:

 

Charter boats troll surface lures until a school is located, then drift live anchovies.  They can be located by either trolling feathers or anchoring at a spot known to be frequented by bluefin tuna, and chumming with live anchovies.  Once the fish are attracted, anglers must use light line (12# test or less), small hooks (#4’s or smaller), and the "hottest" bait available that season (usually live anchovies or pieces of squid).
