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.

Changes to Halibut Fishery in the Bering Sea Being Considered by North Pacific Council

June 16, 2017 — SEAFOOD NEWS — At their June meeting last week, the North Pacific Fisheries Management Council moved forward on a regulatory amendment to allow Western Alaska Community Development Quota (CDQ) groups to lease halibut IFQ during times of low abundance.

The issue has been before the council since December 2015; last week the 11-member panel selected a preferred alternative for further analysis.

Low relative abundance has been an issue throughout the range of Pacific halibut since 2010 or so when the phenomenon of lower size at age became widely discussed. That years-long event, marked by successive generations of halibut not reaching sizes they have in the past at advanced ages, appears to have leveled out in recent years.

Both Individual Fishing Quota (IFQ) and CDQ are issued in units which are converted to pounds, so the problem of lower pounds to fish, in a region defined by few processing plants and vast distances between fishing ports where product is processed and the markets that buy it, continues to affect residents of the Pribilofs and the Aleutian Islands.

In 2015, the issue reached a critical point when the International Pacific Halibut Commission’s (IPHC) stock assessment and harvest policy justified some half a million pounds of halibut in an area where over a million was required to run the plants and allow the fleet to go fishing.

The IPHC’s method for setting annual catch limits uses an equation that removes from the total biomass mortalities that are estimated by each country the year before, for example subsistence removals and bycatch removals.

In the Bering Sea, removals of halibut bycatch in the pursuit of flatfish and P-cod, amounted to 4.6 million pounds, nearly 14 percent of all halibut caught by the directed fishery in both countries that year. Catch limits went down from there in 2016. Additionally, most of the bycatch was smaller than 32-inches, which is the legal limit for the directed fishery.

In June 2015 the Council recognized the need to reduce bycatch in the Bering Sea and set goals for each fishing sector. The Amendment 80 fleet, targeting flatfish that inhabit the same sea floor as halibut, exceeded their reduction targets in the following years.

Any savings in the over 26-inch portion of the groundfish fleets’ halibut bycatch translates the following year as increased catch limits to the directed halibut fleet in the Bering Sea. Any savings of under 26-inch fish is taken into account by the IPHC’s annual stock assessments and improves the overall abundance of the species in that area and other areas affected by out-migration and recruitment to the biomass.

The action taken by the Council to allow CDQ groups to lease IFQ is seen as a stop-gap measure only in times of severely low abundance and until the Council completes their work on shifting the managment of halibut bycatch from a set Prohibited Species Catch (PSC) to an Abundance Based Management (ABM) scheme.

That effort continues at the Council with a step-wise process to establish first, indices that answer the question “Abundance of what?”, for instance just in the Bering Sea, or also the Aleutians or Gulf of Alaska, and a starting point that answers the question “Where do we begin measuring the ratio of what we’re catching with what is out there?”

Analyses will be done this summer for the Council’s consideration and further action at the October meeting.

Alaska Peninsula fisheries could harvest more than 20 million salmon if averages stay true

June 8, 2017 — The Alaskan Peninsula extends from the mainland toward the southwest between the waters of Bristol Bay and Kodiak. There are several commercial fisheries included along its shores and in the archipelagos to the west. If the averages of the past five years stay consistent, these districts could collectively harvest more than 20.6 million salmon this 2017 season.

The South Alaska Peninsula district is expected to carry the lion’s share of this catch. While there is no formal forecast for sockeye, area biologists predict a South Pen pink run ranging up to 15.6 million fish, with a pink harvest projected at 12.4 million.

“It’s a decent year,” said area management biologist Lisa Fox—the outlook being far better than last year’s pink harvest, which was part of a statewide bust. However, pink runs during odd years are generally measured against other odd years. “It’s not going to be as strong as that 2015 year,” said Fox.

ADF&G is projecting a South Pen sockeye harvest of 2.26 million, which is based on the recent five year average. There are three sockeye systems with escapement goals in the South Pen: biologists hope to see 15,000 to 20,000 sockeye in Orzinski Lake, 14,000 to 28,000 in Thin Point, and 3,200 to 6,400 in Mortensen Lagoon.

The Chignik sockeye fishery is on the south side of the Peninsula, just west of Kodiak. Chignik’s sockeye forecast is down from last year, but close to the district’s ten year average. Biologists in the region are forecasting a total run of more than 2 million fish, with an expected commercial harvest of 1.2 million.

Success of Alaska Pollock Fishery is focus of SeaWeb Seafood Summit Panel

SEATTLE (Saving Seafood) — June 7, 2017 — The success of the industrial pollock fishery in the Eastern Bering Sea, which generally harvests in excess of one million metric tons each year, was the focus of a panel at the SeaWeb Seafood Summit on Tuesday. The panel, “Moving Beyond Fishery Certification: Using Collaboration, Technology and Innovation to Further Improve Sustainability” was moderated by Tim Fitzgerald of the Environmental Defense Fund. Panelists were Allen Kimball of Trident Seafoods, Richard Draves of American Seafoods, and Karl Bratvold of Starbound LLC. Trident Seafoods is a large, vertically integrated company, which processes Alaska pollock at shoreside facilities. Vessels owned by Starbound and American Seafoods harvest and process Alaska pollock at sea.

Panelists discussed the development of the Alaska pollock fishery: from before extended jurisdiction through the period of transition to a fully domestic fishery, to the years before rationalization when catcher-processors and catcher vessels competed in an Olympic-style race for fish, to the advent of an effective and efficient enterprise with the establishment of catch shares under the American Fisheries Act (AFA). Under the AFA, quota share is permanently allocated between the at sea and shoreside processing sectors, and among cooperatives (groups of fishing companies) within each sector. AFA provisions encourage cooperation and collaboration within and between sectors and cooperatives, which has brought about many improvements.

Examples of successful collaboration and cooperation include avoidance of salmon bycatch, which is facilitated by comprehensive observer coverage, daily electronic communication of catch and bycatch information that is shared across the fishery, and binding agreements that require vessels to relocate to avoid bycatch or suffer substantive financial penalties. Similarly, collaboration on development of selective gear, development of gear with reduced drag, and other shared innovations have been effective in reducing bycatch and greenhouse gas emissions, and increasing operating efficiency. All of the panelists highlighted their commitment to science-based management, their support for federal government science, and the extent to which they collectively fund scientific research. They also spoke about the importance and value associated with Marine Stewardship Council (MSC) certification.

Additionally, the panelists emphasized the extent to which rationalization through catch shares has improved the harvesting and processing processes, as well as increased safety and operational efficiency.

This session told the story of Alaska pollock and illustrated the benefits of a well crafted and well implemented catch share program, as well as MSC certification. Other fisheries can learn from this experience, but it’s important to note that this is not a “one size fits all” solution that is immediately applicable in all types and scales of fisheries.

China’s Appetite Pushes Fisheries to the Brink

May 1, 2017 — Once upon a time, the seas teemed with mackerel, squid and sardines, and life was good. But now, on opposite sides of the globe, sun-creased fishermen lament as they reel in their nearly empty nets.

“Your net would be so full of fish, you could barely heave it onto the boat,” said Mamadou So, 52, a fisherman in Senegal, gesturing to the meager assortment of tiny fish flapping in his wooden canoe.

A world away in eastern China, Zhu Delong, 75, also shook his head as his net dredged up a disappointing array of pinkie-size shrimp and fledgling yellow croakers. “When I was a kid, you could cast a line out your back door and hook huge yellow croakers,” he said. “Now the sea is empty.”

Overfishing is depleting oceans across the globe, with 90 percent of the world’s fisheries fully exploited or facing collapse, according to the United Nations Food and Agriculture Organization. From Russian king crab fishermen in the west Bering Sea to Mexican ships that poach red snapper off the coast of Florida, unsustainable fishing practices threaten the well-being of millions of people in the developing world who depend on the sea for income and food, experts say.

But China, with its enormous population, growing wealth to buy seafood and the world’s largest fleet of deep-sea fishing vessels, is having an outsize impact on the globe’s oceans.

Having depleted the seas close to home, Chinese fishermen are sailing farther to exploit the waters of other countries, their journeys often subsidized by a government more concerned with domestic unemployment and food security than the health of the world’s oceans and the countries that depend on them.
