Unlike the agile great white shark, known as the king of the ocean, Greenland sharks are more elusive, requiring perhaps even more finesse to capture. The capture of one not only calls for brute strength but demands an emblematic understanding of their habitats.

”Fishing for Greenland sharks is almost like decoding a cryptic language of the fish world,” Ken Fraser, holder of multiple IGFA records, elucidated in one of his interviews. “It’s the rainbow at the end of a deep-sea treasure hunt.”

Techniques and tackle: how these giants were caught

Techniques and tackle: how these giants were caught

Mastering the appropriate gear and tackle

Imagine reeling in a fish that weighs hundreds of pounds—that's no simple feat! Every legendary catch, from Ken Fraser's 1,496-pound Atlantic bluefin tuna in Nova Scotia to Alessandro Biancardi's impressive wels catfish in Italy, required specialized gear and tackle. Not just any rod and reel will do; these anglers relied on top-notch, heavy-duty equipment specifically designed to handle the sheer power and size of these giants. For instance, Fraser’s record bluefin tuna catch was achieved using a rod and reel capable of handling intense strain and pressure.

Strength and technique

Strength and patience play pivotal roles in successfully landing these massive fish. It's not uncommon for battles to last several hours, testing the angler's endurance and skill. Ken Fraser spent over 45 minutes fighting his massive tuna before successfully landing it. Greenland sharks, known for their mysterious deep-sea lives, often require a mix of brute strength and precise technique, as their immense weight and power can easily outmatch standard gear if not handled correctly.

Bait and lures: the essential ingredients

The choice of bait or lure is crucial. Many record-shattering catches, such as the king of the ocean, the great white shark, were tempted with large, natural baits like chunks of fish or squid. In the case of fly fishing for smaller yet significant freshwater giants, specialized flies that mimic the natural food sources of the specific fish species were employed. For example, Alessandro Biancardi's famous wels catfish was lured in using large, robust baits that attracted the giant catfish lurking in European rivers.

Determination meets experience

Veteran anglers often rely on their deep pool of experience and knowledge. Understanding the species' behavior, preferred habitats, and feeding patterns can significantly increase the chances of a successful catch. For example, Biancardi's years of experience fishing in Italy's Po River helped him master the art of baiting and reeling in the truly biggest fish.

The magic of fishing locations

Location is key. The waters off the coast of Florida, known for their thriving population of tiger sharks and bluefin tuna, and the pristine regions of Norway, home to Greenland sharks, reveal how diverse locations contribute to record-breaking fishing. This knowledge allows anglers to pick and prepare the right tackle, making the dream of landing a giant a reality.

The unseen heroes: boats and crews

Small details matter, like the type of boat used and the skills of the crew. In many instances, the crew's expertise plays a massive role in successfully landing these fish. Safe navigation and positioning, as well as helping the angler manage the fish’s enormous power, can be as crucial as the tackle used.From customized heavy-duty gear to the right bait, tackling these magnificent giants demands a mix of technique, strength, and deep-seated knowledge. Each record-breaking catch tells a story of dedication, expertise, and sometimes, a bit of luck.
