  • Alaskan Pacific Halibut Fishing By: Maxwell Scroggins Anica Miller
  • Overview
    • How is this fish collected?
    • Halibut information
    • What is the market for this fish like?
    • What is the impact of this fishing on the ecosystem?
  • Fishing Method
    • Halibut is fished from the ocean with the long line method.
    • In the long line method of fishing a line with thousands of baited hooks is lowered into the water and pulled up later with fish attached.
    • The fishery is managed by the International Pacific Halibut Commission (IPHC)
  • Fishing Location
    • Halibut is located up the west coast from Northern California up to the Gulf of Alaska and Bering Sea
    • Near 100% of all halibut caught in the U.S. Is Pacific Halibut from the Gulf of Alaska
  • The Pacific Halibut
    • Life Span: Males and Females can live to be quite old, the oldest halibut recorded was 55 years old.
    • Size: Halibut can grow up to 500 lbs. and up to 9 ft. in length.
    • Diet: Adult halibut eat other fish such as: sablefish, cod, sculpins, and occasionally smaller halibut
    • Halibut are a flatfish with both eyes on the dorsal side of the body
  • Market
    • Both Pacific and Atlantic halibut are marketed as “Halibut”
    • One of the most valuable fish due to large size and high price.
    • The halibut is exported as well as sold to fish markets and other distributers for use in restaurants and home cooking.
    • The U.S. and Canada are the leading suppliers in the halibut market.
  • Impact on Marine Ecosystem
    • Longline fishing, while less destructive than other methods of fishing, still has a bycatch.
    • Sea birds are the most vulnerable, eating bait off of hooks when lines are being set then being dragged under water and drowned.
    • Sea turtles and sharks also bite hooks and get trapped.
    • Pacific Halibut is not being overfished and populations are strong.
  • Restrictions and Regulations by NMFS
    • In 1995 the NPFMC (North Pacific Fishery Management Council) and NOAA (National Oceanic and Atmospheric Administration) implemented a quota system for Alaska, causing the fishing season to be extended from what was only a few days to 8 months or more. This resulted in lower bycatch and less fisherman deaths.
    • For recreational fishermen there is a total allowable catch limit daily and closed seasons.
