In a properly conducted fight, the line should always be moving. If the fish isn’t pulling drag, you’re pumping and gaining line. The fish should never be allowed to rest, but you are able to when the fish is taking line. On the initial run, with the drag at prestrike, you want the tuna to make a long, fast run under moderate pressure, burning up lots of energy. When it stops, push the drag up closer to strike and start pumping. You’ll gain some line, but the fish will still be fresh, and when it turns to run, it will be against increased drag. When it stops again, push the drag up to strike and pump with an even cadence, turning the fish back to the boat. Frequently you can get the fish to turn and run toward you: If it does, crank as fast as you can in high gear to take advantage of the opportunity. Experienced anglers say this strategy breaks the fish’s will. As it tires, counter each successive run with more resistance to make the fish give up.
