  • International Pacific Halibut Commission

International Pacific Halibut Commission Its mandate is research on and management of the stocks of Pacific halibut (Hippoglossus stenolepis) within the Convention waters of both nations.

The International Pacific Halibut Commission (IPHC) was established by Canada and the United States of America for the preservation of the Pacific halibut fishery. The International Pacific Halibut Commission (IPHC), originally called the International Fisheries Commission, was established in 1923 by a Convention between the governments of Canada and the United States of America. The IPHC consists

of three government-appointed commissioners for each country who serve their terms at the pleasure of the President of the United States of America and the Canadian government respectively. The IPHC, an International Fisheries Organization, receives monies from both the Canadian and USA governments to support a Secretariat. Annually, the IPHC meets to conduct the business of the Commission. At this annual meeting the budgets, research plans, biomass estimates, mortality recommendations, as well as regulatory proposals are discussed and approved then forwarded to the respective governments for implementation. The IPHC Secretariat and offices are currently located in Seattle, Washington, USA. The IPHC conducts numerous projects annually to support both major mandates: stock assessment and basic Pacific halibut biology. Current projects include a Fishery-Independent Setline Survey (FISS) from northern California to the end of the Aleutian Islands, as well as field sampling in major fishing ports to collect scientific information from the Pacific halibut fleet. In conjunction with these ongoing programs, the IPHC conducts numerous biological and scientific experiments to further the understanding and information about Pacific halibut. The Commission encourages public participation in the management of the resource and regularly seeks advice from its subsidiary bodies and various State, Provincial, and Federal agencies.

Hello from Prince Rupert, the City of Rainbows!

There has been a lot of ebb and flow in offload frequency throughout the year with weather being a main driver. There are multiple offloading locations in Prince Rupert and Port Edward where the fish are unloaded, and most are promptly trucked elsewhere for further processing.

My role as a Field Data Specialist is to collect biological data from Pacific halibut when they are offloaded as well as fishing logbook (catch and effort) information from fishing vessel captains. I also collect tagged fish data, distribute tag collection rewards, and act as the sole representative of the IPHC in Prince Rupert and Port Edward, performing other duties as needed. Being part of a collaborative organisation that helps keep the Pacific halibut fishery sustainable is an honor, and I look forward to continuing my work with the IPHC.

Hello from the Emerald Isle, I’m Staci, the IPHC’s Fisheries Data Specialist (Field) in Kodiak, Alaska!

My role is to collect biological data that helps assess the health and sustainability of the Pacific halibut stock. This means gathering otoliths (the inner ear bones used to determine a fish’s age), genetic samples, lengths, and weights. I also work with vessel captains to record gear details, set locations, catch weights, and other factors that influence fishing data.

A big part of my job is making sure all stakeholders’ voices are heard by the Commission because every perspective matters in fisheries management.

This fishing period started off a little slow here in Kodiak, but it picked up quickly! We’ve welcomed vessels from right here at home and as far away as the Aleutian Islands. Thanks to a steady, high Pacific halibut price, spirits are high on the docks. So far this year, I’ve collected over 950 biological samples from over 78 landings, and it’s only my first year with the IPHC!

I feel lucky to be working in such a beautiful place… though to be fair, every IPHC field location is in a spectacular port. Here’s to more great days on the docks and healthy Pacific halibut for the future!

Hello from Unalaska!

I am happy to be working with the incredible Pacific halibut fishery this year, collecting over 1600 otoliths so far! Deliveries began arriving in Dutch Harbor, Alaska in May, increasing in July, and have been holding steady ever since. Otolith (ear bone) collection is an important slice of the data gathered here. The otoliths are the primary structures used to determine the age of a fish, featuring growth rings that can be viewed under a microscope to identify growing seasons, much like the concept of counting tree rings. The growth zones can be made more distinctive with the help of some chemicals; however, this means the otolith can’t be used for other elemental analysis. To provide otoliths for future studies into the fish’s environmental context, a proportion of the otoliths collected here are reserved chemical-free for the Clean Otolith Archive Collection (COAC). These can be used to dig into things such as the temperatures, diets, origins, and migration patterns of the fish.

Getting to see the familiar faces returning to these docks is one of my favorite parts of my job. It takes dedication, skill, and an unwavering spirit to make a living from these waters. Thank you for sharing your stories, your time, and your wisdom!

Hello from the Pacific halibut capital of the world: Homer, Alaska!

It has been another busy and exciting Pacific halibut fishing period here in Homer. The port continues to be one of the most active in IPHC Regulatory Areas 3A and 3B, with steady offloads keeping things moving all summer long. There have been over 300 landings in Homer to date, with 4.45 million pounds of area 3A Pacific halibut caught and 1.54 million pounds of 3B caught. Many vessels have split their time between Pacific halibut and salmon this season, but even with the overlap, the Pacific halibut fleet here has been keeping busy.

As a Fisheries Data Specialist (Field) with the IPHC, my role is to collect both fishing and biological data from Pacific halibut to support sustainable management of the stock. One of the crucial pieces of data we collect are otoliths, which are ear bones used to determine the age of the fish. So far this season, over 1,200 otoliths have been collected here in Homer! Each one helps build a clearer picture of the population and contributes to the coastwide stock assessment.

The community here in Homer is always great to work alongside. Between the active fishing fleet, the lively harbor, and the mix of weather that ranges from calm blue-sky days to raging storms, there’s never a dull moment.

Hello all from St. Paul Island!

2025 is the second year of IPHC sampling returning to this port, and it has been great to be able to work closely with the community out here. So far this season, there are six boats fishing out of St. Paul, each captained by local community members. You can really feel how tight-knit the island is. Whenever a vessel comes in to offload their catch, family members often come by to greet their loved ones and reconnect after a long day of fishing.

The weather changes wildly here from day to day, going from lovely clear blue skies one day to foggy and raining with 40mph gusts the next. But the vessels do not let a little weather scare them. As long as they deem the conditions of the forecast safe, they’ll be out there!

So far, there have been over 500 biological samples taken, and St. Paul is only getting started!

Once again, a big shout-out to the wonderful community and all the fishing crews here on St. Paul Island.

Greetings from Seward, Alaska!

The start of the Pacific halibut fishing period this year was marked by typical back-to-back storms this spring, which kept catch rates down. However, they predictably picked up in May as the weather improved. Many factors determine where vessels will be landing their catch, including weather, price at the dock, distance to fishing grounds, and more. In general, yearly Pacific halibut landings into Seward over the past five years (2020-2024) have been between 7-11% of the total weight landed coastwide. In the 3.5 months of the 2025 fishing period, about 3% has been brought into Seward, so with another 4.5 months to go, I am expecting another 4-7% to be landed here.

As a Fisheries Data Specialist in the field for the IPHC, my job is to collect biological data from Pacific halibut, including age, s*x, length, and weight, as well as log information from captains regarding gear set and locations, total pounds caught per set, and other factors that affect the fishing. Having been with IPHC for several years, I maintain that the biggest reason I keep coming back every year is to be that connecting piece between the industry and the management. Welcome to Seward!

Hello from the Capital!

It has been a rainy spring here in Juneau though that hasn’t deterred the number of Pacific halibut landings making this port relatively busy. Fish seem to be larger than last year with 150 sampled Pacific halibut weighing about 2720kg (6,000lbs), and one sampled fish weighing in at 50kg (112lbs)!

There have been more landings than usual for me this time of year. Vessels have been out fishing steadily, and, as always, Alaskan fishers rise to meet whatever the season brings. I love seeing all the friendly faces and wonderful captains who make my job worthwhile; all feedback and support is much appreciated.

Here's hoping Juneau sees some more sun in the coming days. The rain is refreshing, but I think everyone would like some more sunshine!
