A commercial fishing boat hauled in what may have been one of the oldest creatures in Alaska - a giant rockfish estimated to be about a century old.
The 44-inch, 60-pound female shortraker rockfish was caught last month by the catcher-processor Kodiak Enterprise as it trawled for pollock 2,100 feet below the surface, south of the Pribilof Islands in the Bering Sea.
Scientists at the National Oceanic and Atmospheric Administration at the Alaska Fisheries Science Center in Seattle measured, photographed and documented the fish. They removed an ear bone, the otolith, which contains growth rings similar to rings in the trunks of trees.
They estimate the rockfish was 90 to 115 years old.
That's toward the upper end of the known age limit for shortraker rockfish. Other estimates put the fish's maximum age at 157 years.
Scientists said the specimen is not the biggest on record. A 47-inch shortraker rockfish was recorded, according to the book "Fishes of Alaska
