Alaska's first shellfish hatcheries could be its last, given the impact of growing ocean acidification, according to a new report published in the scientific journal PLOS ONE.

The research -- by the National Oceanic and Atmospheric Administration, the University of Alaska and a shellfish hatchery -- found that in 25 years, Alaska’s coastal waters may not be able to support shellfish hatcheries unless costly new systems are put in place.

The chinook salmon situation is looking more hopeful in the early part of the 2015 season relative to recent years, though not yet in the places where better runs are most needed.

Early king salmon seem to be making a comeback from abysmal showings in the last two years. Key rivers in Southcentral Alaska are seeing returns to normalcy and in some cases returns to states unseen for the last 10 years. Even the hard luck Yukon River is experience stronger showings than the past couple years, although still far less than historic averages.

Witnesses said the young man, whose name and hometown have not been released, was yelling and screaming, and attempted to untie several boats in a line near the southeast end of the harbor.

Police officer Tanner Lowery arrived at the harbor, and attempted to apprehend the man, which no one else at the scene had been able to do. Witnesses said the man jumped off the bow of the boat to avoid the officer.

The slower than expected start to the run has left many wondering if the run is late, smaller than forecast, or about to arrive in one big "wall of fish."

Hidden Falls chum salmon performance is far below the forecast and the fishery will need to be closed in order to ensure broodstock numbers. The broodstock goal is 180,000 fish for the Hidden Falls/Takatz programs (101 million eggs), Deep Inlet (24 million eggs), and Southeast Cove (55 million eggs). NSRAA secured the permit for up to 30 million eggs from DIPAC, and DIPAC has generously agreed to take up to the limit this year. So far about 35,000 chum have been harvested at Hidden Falls; the male ratio from Sunday June 28 was 68%.

Fishermen report slow catches at Coffee Point and Naknek and researcher Bert Lewis tells us about shrinking chinook salmon - plus, a look at catch and escapement numbers, and some run analysis from FRI.

The long-awaited Naknek-Kvichak opener sounded a little slow, but there's another one planned for tomorrow. We also hear from Paul Greenberg about America's fisheries, check-in on the upcoming Southeast Alaska troll season and take a run through the numbers.

Fulfilling the dreams of generations of Petersburg-based fishermen, an unidentified spokesman announced that entities named Convergence and Dominion would purchase Icicle. The spokesman also used both the words synergy and synergize in his/her brief but stirring statement:

According to a spokesperson for the Soetantyo family, who was not identified, Convergence "sees an opportunity to synergize Icicle with our group operations in Indonesia. Though this acquisition, we are accessing a high-quality seafood resource with leading fish and processing capabilities.

A decision by the Pacific Salmon Commission to cap this summer's Alaska harvest of king salmon at 237,000 fish, down from 440,000 fish a year ago, is prompting outrage from the Alaska Trollers Association.

"This year's quota shines a bright light on a treaty agreement that is not working for Southeast Chinook fishermen and communities," said Dale Kelley, executive director of the Alaska Trollers Association.

Today we hear the news the westside has been waiting for - setnets are going in the water - and take a trip from Kachemak Bay to Bristol Bay.

Staff of the North Pacific Fishery Management Council have begun working on a discussion paper for the council’s October meeting, exploring ways to index Bering Sea and Aleutian Island halibut prohibited species catch limits to a metric of halibut biomass.

The Bristol Bay sockeye salmon harvest needs to come in at projection for 2015, or declining sockeye prices could squeeze fishermen throughout the region.

The industry has pressure to catch as much as it can. Volume will have to compensate for sinking salmon prices due to the closure of the Russian markets, the strength of the U.S. dollar against the currencies of key export markets like Japan, high volumes of foreign farmed salmon from Norway, and leftover salmon from 2014 still crowding shelves.

There are less than two weeks to go before the traditional start of the summer king salmon trolling season, on July 1st — but fishermen in Southeast don’t know yet how many kings they’ll be allowed to catch. That’s because representatives on the Pacific Salmon Commission are deadlocked: they can’t agree how many king salmon are out there.

It started with the Copper River and now the harvest of Alaska’s wild salmon is growing quickly, as fisheries in the Alaska Peninsula, Kodiak , Cook Inlet, the Yukon River, and Bristol Bay start to kick in.

The Alaska salmon return for 2015 is posed to set new records - forecasts show harvests of 221 million salmon, equating to about 1 billion pounds, reports Rob Reierson in the Tradex Foods 3-Minute Market Insight.

Commercial harvesters in the Copper River drift fishery harvested an estimated 940,000 wild salmon through June 15, and the overall Prince William Sound harvest reached 1.7 million fish.

That's according to the estimated in-season statewide harvest posted online daily by the Alaska Department of Fish and Game.

State biologists estimate a total of 946,000 sockeyes have been caught in Prince William Sound, including 907,000 reds in the Copper River drift fishery, where harvesters have also caught some 20,000 kings.

LOWER RUSSIAN LAKE -- What the heck’s a weir, anyway?

“It’s French for fence,” explained Alaska Department of Fish and Game Area Management Biologist Robert Begich.

Put simply, the fish weirs used by the department are typically long aluminum dam-like grates that extend the width of a river or creek to impede fish passage. Salmon migrating upstream to spawn are trapped behind the structure, which includes a small door through which technicians can allow fish to move through one at a time. This lets workers click off each fish on hand counters as the salmon pass.

Four people are safe after their fishing tender sank off Cape Fairweather early Wednesday morning (6-10-15).

A helicopter from Air Station Sitka hoisted the crew of the 80-foot tender, just as the vessel rolled and sank in six-foot seas near Lituya Bay.

The Kupreanof was en route from Petersburg to Bristol Bay to tender salmon when it ran into trouble at about 3:45 AM in an area known as the Fairweather grounds, about 110 miles northwest of Sitka.

First, the important question: How bad does 200 tons of cod liver smell?

Not bad at all, say the investors behind a new effort to parlay mountains of once-discarded fish livers into a nutritional supplement bursting with Bering Sea goodness.

Mediation talks are set to begin June 8 in Seattle regarding participation in a Marine Stewardship Council client group for Alaska salmon certification held by the Seattle-based Alaska Seafood Processors Association.

KDLG's Molly Dischner has June 8's Bristol Bay Fisheries Report. Tonight fisheries analyst Andy Wink talks about the market for sockeye salmon, we hear about the Bristol Bay Regional Seafood Development Association's annual meeting in Dillingham, and we check in on the new halibut bycatch caps set in Sitka Sunday evening.

After several days of emotional testimony, the North Pacific Fishery Management Council voted on Sunday afternoon to reduce limits on halibut bycatch in the Bering Sea – by 21 percent overall.

Many in the groundfish fleet say it will take a big toll on their industry. But halibut fishermen in the Bering Sea say the cut isn’t big enough to save their communities.

The Bering Sea is a tough, unforgiving environment. As Alaska Native peoples we have survived and flourished for thousands of years by sustainably harvesting this sea’s bounty, including the noble Pacific halibut. Our home, the island of Saint Paul in the Pribilof Islands, is located in the central Bering Sea in the heart of the nation’s richest commercial fisheries.

In Sunday’s guest column, the Central Bering Sea Fishermen’s Association referred to trawl fishing as a grave threat and an “environmentally disastrous policy” that has devastated their halibut fishery and “plundered the Bering Sea.”

In two unanimous decisions, the Alaska Supreme Court on Friday came down solidly on the side of a group fighting the proposed Pebble mine, backing efforts by two Alaska icons, former first lady Bella Hammond and state constitutional convention delegate Vic Fischer, to give the public a voice in mineral exploration.

As a fishery scientist who has worked for more than 20 years with trawl fishermen to reduce salmon, crab and halibut bycatch, I find the recent rhetoric around proposed North Pacific Fisheries Management Council changes to the Bering Sea halibut bycatch cap very frustrating. In particular, I hear media campaigns underwritten by environmental NGOs claiming, “It’s been 20 years since the halibut bycatch cap was last reduced,” implying that this has created a conservation issue.

Today, the Alaska Supreme Court issued an opinion that protects Alaskan’s right to know about — and to have a say in — how their resources are used. The Court ruled the Alaska Constitution requires the Alaska Department of Natural Resources (DNR) to provide public notice and to evaluate whether exploration activities for the proposed Pebble Mine are in the public interest. The Court said it best: “The state must know how it should act before it acts.”

The Marine Stewardship Council will facilitate mediation for the salmon processors who disagree about who can participate in the client group that has the council’s sustainability certification. Back in April, ten of Alaska’s major salmon buyers asked to rejoin the label they dropped in 2012, saying it will help them tap back into picky European markets.
