Holy Halibut: A Giant From the Depths of Alaska
Some catches become stories. Others become legends.
This massive Pacific halibut, weighing an astonishing 396 pounds, was landed by Petersburg fishermen Brian Mattson and Doug Corl while longlining in the waters of Frederick Sound near Thomas Bay, Alaska. What began as a routine day on the water quickly turned into a moment neither fisherman will ever forget.
The giant fish stayed surprisingly calm throughout the haul. In fact, the crew did not even realize what they had hooked until it appeared near the surface. As the line kept coming in and the fish kept rising from the depths, it became clear they were dealing with something extraordinary.
Measuring more than 92 inches in length, the halibut was initially estimated to weigh well over 400 pounds. After official measurements, the fish tipped the scales at 396 pounds. While it fell short of the world record, it remains one of the most impressive halibut catches seen in the region in recent years.
Thanks to the powerful winches aboard the F/V Day Spring, the crew was able to bring the giant fish aboard safely. Many smaller fishing vessels would have faced a serious challenge handling a halibut of this size.
The fish was later delivered to Petersburg Fisheries Inc., where workers and onlookers gathered to witness the arrival of one of the largest halibut most had ever seen. Standing beside grown adults, the fish looked more like a creature from a sea monster tale than something caught on a commercial fishing line.
For fishermen who spend countless hours battling weather, tides, and uncertainty, moments like this are a reminder of why they love the sea. Out in the cold waters of Alaska, you never know what might be waiting below.
