| Putting all these elements together really paid dividends: we always came back with fish, usually with several good-sized mackerel. In fact, our average catch was much bigger that those caught by others. This was, I am sure, because we always used natural bait and trolled slow and deep. Lures would only catch small mackerel, apparently not as smart as their elders, who were still not as smart as we were. In truth, a lot of fish got away. It seems that mackerel normally strike at fish with the aim of immobilising them, then come back to swallow them. We would rely on our three-ganged hooks (illegal in competitive game-fishing) to take hold on that first strike, but at least half of all strikes would result in a shredded bait and no hook-up. Marlin fisherman have a similar problem, although I not sure whether marlin strike the bait first with their bills, or perhaps just take time to swallow the bait. The problem is solved by using outriggers. The line is run through a clip on the outrigger and there is a length of slack line between the clip and the tip of the rod. When the fish strikes, the clip lets go, and the slack line allows the bait to lie motionless in the water for a few seconds. I never tried this technique in my tiny boat, but it would have been a worthwhile experiment. Some would say that David and I became obsessed with catching mackerel. We certainly became very keen. We bought proper Everol and Penn game-fishing reels, rods with roller runners and rod-buckets to go with the rods. We upgraded to stainless-steel hooks and Sampo swivels. I bought an echo-sounder so that we could easily find the magic twenty-fathom line beside the step drop-offs. David once accused me of spending so much time peering at this machine that it had become an end in itself, rather than the means to an end: getting large mackerel into the boat. For us, mackerel were the perfect game-fish. There was no guarantee of success after a strike, or even after a hook-up. When the fish was hooked properly, the reel would spin crazily as a couple of hundred metres or so of line disappeared into the sea at a tremendous rate. These fish were really fast, although they didn't have a lot of stamina, so that there was usually just the one long run and another shorter one when the fish saw the boat. Then we often had trouble getting larger fish in the boat. We used a gaff with a short wooden handle and we had to get it right the first time. If we missed with our first swing, the fish was usually still strong enough to break free. The biggest I ever caught was about 23 Kg, but I am sure we lost much bigger ones right up at the boat. Another attribute of the narrow-barred Spanish mackerel is that it is good eating. Because its white flesh is slightly oily, a mackerel steak does not dry out while it is being cooked. I like my fish fresh and cooked simply: coated both sides with soy sauce, grilled until just cooked through, then sprinkled with lemon juice. Another of my favourites is what the Fijians call kokoda, which is cubes of fish marinated in lime or lemon juice, then in coconut cream. It is served uncooked, but the result is quite different from sashimi, because the lime juice has in effect cooked the fish, so that it is no longer soft and translucent, but firm and white. |
