Bristol Bay red king crab quota caught

November 24, 2017 — The Bristol Bay red king crab season finished up last week when the entire allowable catch was harvested.

“The Bristol Bay Red King Crab fishery went fairly well,” said Miranda Westphal, the area management biologist for the Alaska Department of Fish and Game in Dutch Harbor. “A little slower than we would like to have seen, but they wrapped up with a total catch of 6.59 million pounds. So they caught all of the catch that was available for the season.”

Before the season opened on October 15, ADF&G and the National Marine Fisheries Service completed an analysis of the 2017 NMFS trawl survey results for Bristol Bay red king crab.

ALASKA: Bering Sea Pollock and Cod in Good Shape But Could Be Moving North

November 17, 2017 — SEAFOOD NEWS — The North Pacific Fisheries Management Council’s Groundfish Plan Team recommended an allowable biological catch (ABC) for 2018 of Pacific cod in the Eastern Bering Sea of 172,000 mt down from this year’s ABC of 239,000 mt.

The actual catch limits will be determined by the North Pacific Fisheries Management Council in early December.

Reasons for the downturn in ABC were:

* a 46% drop from 2016 to 2017 in the EBS shelf trawl survey abundance, or numbers of fish — the biggest drop in history.

* A 37% drop in EBS biomass (weight) from 2016 to 2017 — also the biggest in history.

There is good news for P-cod elsewhere near the Bering Sea, though. In the Aleutians, which supports a much smaller P-cod fishery, survey biomass is on a general upward trend — 15% each year since 2012.

There, the recommended ABC for this year increased to 22,700 mt from last year’s 21,500 mt.

And in the northern Bering Sea — there is serious consideration that stocks of P-cod and pollock that would normally be in the EBS may be spending more time during the summer in the northern areas.

The Northern Bering Sea survey indices show the relative change in biomass there from 2010 to 2017 as an increase of 907%. Relative change in abundance (numbers of fish) during that time is up 1421%. NBS biomass in 2017 is equal to 83% of the biomass change in the Eastern Bering Sea.

The Plan Team posed a question at the end of the presentation: “Given that the cause of the decline in EBS survey biomass is unknown, but that one plausible hypothesis is that a substantial portion of the biomass simply moved to the NBS survey area while remaining part of the same spawning population as the fish in the EBS survey area, does the given model impose drastic reductions in ABC that have a significant probability of later being shown to have been unnecessary?”

As of November 4 the catch of PCod in BSAI was 186,800 mt.

Pollock changes ahead

Pollock stocks look healthy enough for the Plan Team to recommend an ABC at 2.592 million mt in 2018 and 2.467 million mt in 2019. This reflects slight decrease in biomass from the ABC previously set for 2017 of 2.8 million mt, with a forecasted 2.9 million mt for 2018.

The current TAC for pollock in BSAI is 1.345 million mt. a slight increase over 2016’s TAC of 1.34 million mt.

The key factors scientists are looking at for Bering Sea pollock are:

* A potential decline described as being “expected, quite quickly”

* Is there a shift in distribution? The ecosystem survey in the northern Bering Sea this summer found increases in pollock.

* There are relatively few one-year-old pollock in the 2017 trawl survey.

* Future catches near current levels will require more effort.

The presentation noted “..the ability to catch the same amount as in 2017 through to 2020 will require about 35% more effort with a decline in spawning biomass of about 28% compared to the current level (based on expected average recruitment).”

Calculating the value of Alaska seafood

October 26, 2017 — Alaska has produced more than 169 billion pounds of fish since statehood was granted to the Last Frontier in 1959, and the Alaskan seafood industry brings in enough product annually to feed every person in the world a serving of Alaskan seafood.

These and other statistics relating to the seafood industry in the state can be found in “The Economic Value of Alaska’s Seafood Industry,” a joint report by The Alaska Seafood Marketing Institute (ASMI) and the McDowell Group, a research and consulting firm, which details the impact of Alaska’s seafood economy. This is the second collaboration over the past two years between the groups.

The report is meant to provide statistics and figures on employment in the industry, labor income, seafood value, exports, and other related subjects. From fun facts (Alaska’s commercial fishing fleet is comprised of about 9,400 boats, which would measure 70 miles if they were lined up from bow to stern in a straight line) to precise tax numbers, the report is a gold mine of research about the Alaskan seafood industry.

The report reveals that in 2016, Alaska’s seafood harvest of 5.6 billion pounds had a total value of USD 1.7 billion (EUR 1.4 billion). Processors in Alaska produced 2.7 billion pounds of Alaska seafood products last year, valued at USD 4.2 billion (EUR 3.6 billion). The overall impact of Alaska’s seafood industry on the U.S. economy is USD 5.4 billion (EUR 4.6 billion) in direct output – that’s value that can be directly associated with fishing, processing, distribution, and retail. Such a figure doesn’t include USD 7.3 billion (EUR 6.2 billion) in additional multiplier effects generated as industry income circulates throughout the U.S. economy, the report said.

Big Alaska salmon harvest about 5 percent more than forecast

September 12, 2017 — Alaska’s salmon season is nearly a wrap but fall remains as one of the fishing industry’s busiest times of the year.

For salmon, the catch of 213 million has surpassed the forecast by 9 million fish. High points include a statewide sockeye catch topping 50 million for the 10th time in history (37 million from Bristol Bay), and one of the best chum harvests ever at more than 22 million fish.

Total catches and values by region will be released by state fishery managers in November.

Hundreds of boats are now fishing for cod following Sept. 1 openers in Prince William Sound, Cook Inlet, Kodiak and throughout the Bering Sea.

Pollock fishing reopened to Gulf of Alaska trawlers Aug. 25. More than 3 billion pounds of pollock will be landed this year in Alaska’s Gulf and Bering Sea fisheries. Fishing also is ongoing for Atka mackerel, perch, various flounders, rockfish and more.

ALASKA: Fleet consolidation and loss of fishing jobs a hot topic at MSA hearing

August 28, 2017 — Timed to coincide with the 25th annual Kenai River Classic invitation-only fishing derby, Senator Dan Sullivan brought his Subcommittee on Oceans, Atmosphere, Fisheries, and Coast Guard to Soldotna on Wednesday for a hearing on the reauthorization of the Magnuson-Stevens Fishery Conservation and Management Act.

Congress periodically reviews the Act, giving lawmakers a chance to fine-tune or make changes where needed. One theme was addressed by many of the dozen invited experts who testified.

Fleet consolidation is a predictable outcome of limited access privilege fisheries, or LAPs in the acronym-filled parlance of the Magnuson-Stevens Act, or MSA. A limited access fishery is one that has been privatized in some way. For example, in the Bering Sea, the crab fishery was rationalized more than 10 years ago, resulting in a fleet today that is just a fraction the size it was before privatization. That’s because when the owners of boats also became the owners of crab quota, they could buy or lease that quota, and one boat could do the fishing of many. Some put the loss of crewman and skipper jobs from the year before rationalization to the next at over 900.

“In Alaska, the problem is now too few fishermen, not too few fish,” Linda Behnken of Sitka said. Behnken testified on behalf of the Halibut Coalition and the Longline Fishermen’s Association.

Alaska’s Salmon Harvest Nears 48 Million Fish

July 18, 2017 — Preliminary harvest data show the catch in Alaska’s wild salmon fisheries is nearing the 48 million fish mark. The Alaska Department of Fish and Game’s (ASF&G) count includes 31.6 million sockeyes, 8.4 million chums, 7.6 million pinks, 198,000 silvers and 193,000 Chinook salmon.

More than 25 million of those sockeyes were caught in the Bristol Bay fishery, including 9.6 million in the Nushagak district, 8 million in the Egegik district, in excess of 4 million in the Naknek-Kvichak district and 2.2 million in the Ugashik district.

State fisheries biologist Tim Sands, Dillingham, Alaska, described the sockeye fishery in the Nushagak district as “gangbusters,” as fishermen there brought in a record 1.2 million salmon on July 3. It was the second time this year, and in the history of the Nushagak district, that the daily sockeye salmon harvest exceeded one million reds, Sands said.

Processors on the Lower Yukon have taken deliver of some 331,000 oil rich keta salmon, and another 66,000 keta salmon were caught on the Upper Yukon.

Processors in Prince William Sound have received 7.9 million fish, including 482,000 Copper River reds and another 417,000 sockeyes from the Eshamy District, 51,000 from the Coghill District, 33,000 from the PWS general seine fishery, 2,000 from the Bering River drift and 1,000 from the Unakwik District drift fisheries.

NOAA to Deploy Saildrones for Climate Study

July 18, 2017 — During the next four months, NOAA scientists will deploy Saildrone unmanned ocean vehicles to hard-to-reach locales such as the Arctic and the tropical Pacific with the goal of better understanding of how ocean changes affect weather, climate, fisheries and marine mammals.

The Saildrone is wind and solar-powered research vehicle resembling a sailboat, capable of performing tasks at sea such as met ocean data collection, environmental monitoring and fish stock analysis, autonomously or under remote control. For NOAA, the vehicles will soon travel thousands of miles across the ocean, reaching some areas never before surveyed with such specialized technology.

In mid-July, scientists will send off the first unmanned, wind and solar-powered vehicles from Dutch Harbor, Alaska, with two sailing north through the Bering Strait into the Arctic Ocean and another transiting the Bering Sea. Traversing Alaska’s inhospitable waters, the remote-controlled vehicles will track melting ice, measure carbon dioxide in the ocean and count fish, seals and whales.

For the first time, the vehicles will journey through the Bering Strait into the Arctic with a newly adapted system to measure CO2 concentrations.

We want to understand how changes in the Arctic may affect large-scale climate and weather systems as well as ecosystems that support valuable fish stocks,” said Jessica Cross, an oceanographer at NOAA Research’s Pacific Marine Environmental Laboratory, who is using the unmanned system to study how the Arctic Ocean is absorbing carbon dioxide.

‘Fishal recognition’ for better fisheries management

June 29, 2017 — To monitor fish stocks in about 3 million square miles of ocean including the North Pacific Ocean and East Bering Sea, the Alaska Fisheries Science Center turned to facial recognition technology — or more accurately, “fishal recognition.”

Part of the National Oceanic and Atmospheric Administration’s National Marine Fisheries Service, the center is working to get more accurate counts of marine life by applying the same facial recognition techniques that identify people to recognize fish according to their facial features underwater.

The agency began experimenting with this technology several years ago and is now on its second generation of camera-based trawl, or CAM-Trawl. It has worked with ADL Embedded Solutions on hardware improvements, such as small form factor embedded Vision Boxes — the image acquisition computers — a Quad-Core Intel Core i7 processor to enable real-time processing of image data and waterproof enclosures and connectors.

Before using CAM-Trawl, the traditional method of measuring fish stocks had been to use trawlers to scoop up all the fish in a particular region of the ocean, bring them on deck, count them and then multiply that number out, according to said JC Ramirez, director of engineering at ADL.  “If you did 10 square miles, multiply that by 10 for 100,” for example, he said.

But that method had several shortcomings, including extrapolation errors, high costs and ecological impacts on fish populations.

“They were looking for not only a more benign way to do that, but also perhaps a way that would allow them to cover more regions and get a little bit more specificity on the variations in the data from area to area,” Ramirez said.

Now researchers can pull a rig outfitted with the cameras that are linked back to ADL’s control computer, which typically resides in the wheelhouse. It monitors external sensors such as location, time, pressure sensors and radio frequency identification tag readings. It then, based on sensor input, communicates with one or more Vision Boxes to do the image capture, managing the remote on/off power, clock syncing, and starting and stopping of image collection.

Prehistoric stone fish trap discovered on Alaska island

June 29, 2017 — Archaeologists have discovered a prehistoric fish trap constructed of rock walls near the mouth of a salmon stream on Alaska’s Kodiak Island.

The trap is in a lower intertidal zone that’s covered by ocean water at high tide and exposed at low tide, the Kodiak Daily Mirror reported (http://bit.ly/2t0of5f) Tuesday.

Archaeologists at the Alutiiq Museum in the city of Kodiak identified the trap. Salmon at high tide could swim into the stream, and when the tide receded, fish would be stranded in one of two corrals, said Patrick Saltonstall, the museum’s curator of archaeology.

Prehistoric fish traps previously have been found in streams on Kodiak, the second largest island in the United States, Saltonstall said. The V-shape devices faced upstream and channeled salmon to a spot where fishermen could spear fish. Saltonstall had not seen an ocean trap on Kodiak before.

“These are the first ones we’ve found in the intertidal zone, and that’s kind of exciting,” he said.

The trap reminded Saltonstall of stone walls of a New England farm.

“They’re pretty big piles. They’re like four or five feet across. They’re stacked,” he said. Wood or netting may have helped capture fish.

One corral was roughly rectangular. Farther from shore was a U-shape corral. Together they stretched about 165 yards (150 meters).

The trap is not in shape to catch fish now.

“The walls have gotten too low and they’re too many gaps,” Saltonstall said, likely from tides knocking down rocks over centuries or silt covering the base. Large rocks anchor the trap but most rocks, weighing around 80 pounds (36 kilograms), would have been carried and stacked by hand.

ALASKA: In a Bering Sea battle of killer whales vs. fishermen, the whales are winning

June 20, 2017 — In the Bering Sea, near the edge the continental shelf, fishermen are trying to escape a predator that seems to outwit them at every turn, stripping their fishing lines and lurking behind their vessels.

The predators are pods of killer whales chasing down the halibut and black cod caught by longline fishermen. Fishermen say the whales are becoming a common sight — and problem — in recent years, as they’ve gone from an occasional pest to apparently targeting the fishermen’s lines.

Fishermen say they can harvest 20,000 to 30,000 pounds of halibut in a single day, only to harvest next to nothing the next when a pod of killer whales recognizes their boat. The hooks will be stripped clean, longtime Bering Sea longliner Jay Hebert said in a phone interview this week. Sometimes there will be just halibut “lips” still attached to hooks — if anything at all.

“It’s kind of like a primordial struggle,” fisherman Buck Laukitis said about the orcas last week. “It comes at a real cost.”

The whales seem to be targeting specific boats, fisherman Jeff Kauffman said in a phone interview. FV Oracle Captain Robert Hanson said juvenile whales are starting to show up, and he thinks the mothers are teaching the young to go for the halibut and black cod the fishermen are trying to catch.

Hanson, a fisherman who’s worked in the Bering Sea since 1992, said the orca problem has become “systemic” in recent years. There are more pods present, he said, and the animals are getting more aggressive.

In a letter he sent to the North Pacific Fisheries Management Council last month, Hanson described a series of challenges he faced in recent years. On a trip to the continental shelf in April he said his crew was “harassed nonstop.” He wrote that they lost approximately 12,000 pounds of sellable halibut to the whales and wasted 4,000 gallons of fuel trying to outrun them.
