Plenty of anchovies in Monterey Bay, but maybe not elsewhere
Monterey >> Things are shifting for fishermen in Monterey Bay.Market squid are disappearing, and in their place, fishing boats are reeling in piles of anchovies.But while they appear abundant, conservation groups warn that the forage fish may be at their lowest levels since the 1950s.“It’s an anomalous year,” said Diane Pleschner-Steele, executive director of the California Wetfish Producers Association. “Typically these are not the kind of oceanographic conditions that anchovy like. But they are here and they’re really close to shore, which is why we’re having a spectacular year for whale watching.”Anchovies aren’t just bringing whales into the bay — they’re also attracting fishing fleets.“There are thousands of tons,” said Sal Tringali, president of Monterey Fish Company, whose fishermen in Moss Landing are landing about 120 tons of anchovies each night and expect to do so for about another month. “There are all the anchovies you want out here.”Tringali said the majority of his harvest never fills human bellies, as roughly 70 percent of the catch travels to Australia to feed tuna.Records from the California Department of Fish and Wildlife show that, across the state, fishermen landed 13,508 metric tons of anchovies this year.That number was fine in previous years, but now it’s dangerous, said Geoff Shester of conservation group Oceana.“This level of catch is sustainable when the stock is healthy,” Shester said. “But new information shows that the stock is at such a low level right now, it’s literally in a state of collapse.”Survey cruises conducted by the Southwest Fisheries Science Center detected little to no anchovy eggs from 2010 to 2013. The lack of eggs, coupled with a recent study still in review that suggests anchovy biomass has decreased by over 99 percent from 2005 to 2009, has Shester and his fellow conservationists concerned.“Every ton we can keep in the water is extremely valuable for the future of anchovies and the amazing multimillion-dollar whale-watching and wildlife-viewing destination that is Monterey Bay,” Shester said.Shester, along with representatives from four other conservation groups, recently sent a letter to the Pacific Fisheries Management Council, which oversees fisheries from Washington to California, urging the council to reconsider its anchovy management strategy and conduct a new stock assessment. They argue that because the last anchovy assessment was taken in 1995, current management policy doesn’t apply to modern numbers.Sit on the docks where anchovies are sorted and you’ll likely see lots of the silvery fish piling up. But it’s a mirage, warns William Sydeman, ecologist of the Farallon Institute, who coauthored the paper that estimated anchovies at low levels.“People think that if they’re in Monterey Bay, they must be everywhere,” Sydeman said. “They’re not. They’re only in Monterey Bay.”Sydeman said anchovies tend to aggregate near shore when their numbers are low, giving the appearance of abundance. When numbers are actually strong, he said, the fish expand offshore, disappearing from sight.“People think, ‘Oh look at all these whales, there must be a ton of fish,’ and that’s probably true,” said Sydeman. “There is a local abundance of anchovies. But it’s local. That doesn’t mean global abundance.”The National Marine Fisheries Service enforces a cap on anchovies. Josh Lindsay, policy analyst for the service, believes that number is conservative.“To take a precautionary approach,” Lindsay said, “we took the overfishing limit and told the fishing fleet that they could only catch 25,000 metric tons. That’s a pretty large buffer built into our management.”The Pacific Fishery Management Council will meet next month to review the latest findings on anchovy numbers.

New research maps areas most vulnerable to ocean acidification

New NOAA-led research maps the distribution of aragonite saturation state in both surface and subsurface waters of the global ocean and provides further evidence that ocean acidification is happening on a global scale. The study identifies the Arctic and Antarctic oceans, and the upwelling ocean waters off the west coasts of North America, South America and Africa as regions that are especially vulnerable to ocean acidification."These findings will help us better understand and develop strategies to adapt to the severity of ocean acidification in different marine ecosystems around the world," said Richard A. Feely, a NOAA oceanographer and co-author of the study, which has been accepted for publication and can be read online in the American Geophysical Union journal Global Biogeochemical Cycles.Ocean acidification is caused by humankind's release of carbon dioxide emissions to the atmosphere. Excess carbon dioxide enters the ocean, reacts with water, decreases ocean pH and lowers carbonate ion concentrations, making waters more corrosive to marine species that need carbonate ions and dissolved calcium to build and maintain healthy shells and skeletons. The saturation state of seawater for a mineral such as aragonite is a measure of the potential for the mineral to form or to dissolve.In the new study, scientists determined the saturation state of aragonite in order to map regions that are vulnerable to ocean acidification. Waters with higher aragonite saturation state tend to be better able to support shellfish, coral and other species that use this mineral to build and maintain their shells and other hard parts.This study shows that aragonite saturation state in waters shallower than 328 feet or 100 meters depth decreased by an average of 0.4 percent per year from the decade spanning 1989-1998 to the decade spanning 1998-2010. "A decline in the saturation state of carbonate minerals, especially aragonite, is a good indicator of a rise in ocean acidification," said Li-Qing Jiang, an oceanographer with NOAA's Cooperative Institute for Climate and Satellites at the University of Maryland and lead author.The most vulnerable areas of the global ocean are being hit with a double whammy of sorts. In these areas, deep ocean waters that are naturally rich in carbon dioxide are upwelling and mixing with surface waters that are absorbing carbon dioxide from the atmosphere. The carbon dioxide from the atmosphere is coming primarily from human-caused fossil fuel emissions."When oyster larvae are born they must draw on the energy in their yolk to build their aragonite shells to protect themselves from predators and grow into healthy adults," said Feely. In waters depleted of carbonate ions, young oysters must expend more energy to build their shell and may not survive. This has significant consequences for the seafood industry."

Scientists Say Fish Are the World’s Best Athletes

Humans toss around sports titles like they own them. “World’s Greatest Athlete.” “World Record Holder.” “Fastest Alive.”Name any winner at any Olympics at any event in track and field and this much is almost certain, a new research paper argues: A wide variety of athletic fish would blow right by them. Trout, salmon, tuna and other fleet fish are capable of producing far more oxygen in their bodies for mind-blowing performance."Fish exploit a mechanism that is up to 50-times more effective in releasing oxygen to their tissues than that found in humans," said Jodie Rummer, the lead author of the study and a researcher at the ARC Centre of Excellence for Coral Reef Studies at James Cook University."This is because their hemoglobin, the protein in blood that transports oxygen, is more sensitive to changes in pH than ours and more than the hemoglobin in other animals," she said.That’s right, other animals. The humble trout and salmon, not to mention powerful tuna, can also blow away some of the fastest mammals on land.Fish have developed this ability for longer than humans can imagine, given their standing as some of the first organisms to form hundreds of millions of years ago. Humans run marathons. Salmon swim entire coastlines and tuna swim around the world.When they’re challenged – which generally means chased by predators – they really get on their horse, flying underwater at incredible speeds. Humans catch them easily, but advance fishing tools and methods cheat nature.A quick getaway from predators isn’t the only skill fish evolved to survive. Conditions in water can change dramatically, especially with humans around adding phosphorous, nitrogen and acidity to water.In areas of low oxygen in water, such as a problem known as dead zones that leave them sucking for air, they can double or triple oxygen delivery to their tissue. The study was published early this week in the journal PLOS One.Researchers have used rainbow trout to understand how fish deliver oxygen for the past decade. First they tested how it's done by monitoring rainbow trout muscle oxygen levels in real-time. Then they compared the results with medical studies of humans to show how much more powerful fish like trout and salmon are.“This information tells us how fish have adapted this very important process of getting oxygen and delivering it to where it needs to be so that they can live in all kinds of conditions, warm or cold water, and water with low oxygen levels,” Rummer said.Many elite runners have taken to wearing elevation training masks that reduce their oxygen intake, hoping to simulate breathing at a higher altitude to better their performance. Fish don’t need a mask. They’re born that way.“This trait may be particularly central to performance in athletic species, such as long-distance swimming salmon or fast swimming tuna,” said Colin Brauner, a University of British Columbia researcher and study co-author.“For fish,” he said, “enhanced oxygen delivery may be one of the most important adaptations of their 400-million-year evolutionary history.”

Oncoming El Niño likely to continue species shakeup in Pacific

One-two punch of El Niño and "warm blob" could boost coastal temperatures and supercharge storms
Contributed by Michael MilsteinThe emerging El Niño climate pattern that is warming the tropical Pacific Ocean is likely to continue–and could even increase–the appearance of marine species in unfamiliar places along the West Coast. This trend started with a vast "warm blob" of high temperature waters that has dominated the Northeast Pacific since 2014.Previous El Niños coincided with large-scale redistribution of some West Coast marine mammals, fish and sea turtles. The combination of an anticipated strong El Niño and the blob may do the same, possibly in new and different ways, NOAA Fisheries researchers say."One of our big questions right now is, how can we best link observed changes in species distributions to changing environmental conditions?" said Dave Weller of the Southwest Fisheries Science Center in La Jolla, California. Weller is chief scientist for the ongoing Collaborative Large Whale Survey, a joint survey for whales off the West Coast and Southeast Alaska by the SWFSC and Alaska Fisheries Science Center."We need to be clever about it in terms of using a range of observations and having eyes on the water in the form of ship surveys like this can really help," Weller said.NOAA Fisheries scientists have been tracking the blob since last year and are cooperatively following continued changes in ocean conditions through at-sea surveys, remote sensing and automated monitoring to understand how the changes are affecting marine ecosystems.The blob has already driven temperatures in the North Pacific some 3 to 4 degrees C (about 5 to 7 degrees F) above average. Not since records began around 1900 have temperatures in the region been so warm for so long.
Temperature changes shift marine life
Already in the last month the survey spotted about 25 pilot whales around 50 miles off the Central California Coast. Pilot whales were once common off Southern California but largely disappeared following a strong El Niño pattern in the early 1980s. In the last few years pilot whales have begun to trickle back into the area, a sign they may be starting to reoccupy former habitat."This recent uptick in pilot whale sightings may be related to the warm blob's influence," Weller said. "If we pay close attention to the animals, they're telling us something about changes in their environment. We now need to connect the puzzle pieces." Scientists are also investigating connections between the blob and a harmful algal bloom along the West Coast that may be a factor in an unusual number of whale deaths in Alaska.Rockfish surveys conducted by the SWFSC in May and June already showed the likely influence of warm water from the blob, turning up large catches of species typically seen during strong El Niño periods, and some never before seen in the survey. They included record high catches of pelagic red crabs and California spiny lobster, and the survey's first-ever catches of warm-water species including greater Argonaut (a swimming octopus with a shell), slender snipefish and subtropical krill.Offshore surveys by the AFSC pulled in warmer-water species including two large ocean sunfish and market squid, species which have not been seen in the prior 18 years of sampling, said Joe Orsi of the AFSC's Auke Bay Laboratories. Other warm-water species reported from Alaska recently include albacore, bonito and yellowtail."This El Niño is liable to bring some really strange changes in ocean conditions because the widespread warming of the North Pacific we saw with the blob was so far outside of our experience," said Northwest Fisheries Science Center oceanographer Bill Peterson. "When you put an El Niño on top of that it is anyone's guess as to how this will affect marine organisms." He tracks types of plankton off the Central Oregon Coast for insight into ocean conditions. He expects a new surge of warm-water plankton as the tropical El Niño begins to influence Oregon waters this fall.Salmon and other species that thrive in cold water often do poorly in warm years, especially strong El Niño years, he noted, while species such as sardines that favor warmer water could do better.
El Nino vs. the blob
Now another key question is how the tropical El Niño and the blob may interact as El Niño gains strength and begins to affect the West Coast this fall and winter. In terms of size, El Niño far exceeds the blob and is expected to pummel the blob with storms that will likely break up the blob and push its warm water up along much of the West Coast, said Nate Mantua, leader of the SWFSC's Landscape Ecology Team.That will likely make this the third winter in a row with record-high coastal temperatures that affect both marine ecosystems and the coastal climate. El Niño typically shifts the jet stream in a way that redirects storms from the Pacific Northwest to Southern California instead."Because we're starting from an exceptionally high baseline temperature this could take us further into uncharted territory in terms of effects," Mantua said.He said there is potential for the warm coastal temperatures to "supercharge" storms spawned by El Niño. Since warmer air holds more moisture storms may carry greater precipitation ashore, which could lead to more intense deluges on land. That could multiply the impacts of this summer's large wildfires by pouring water on recently burned slopes."If you put heavy rains on that, you can get mudslides, debris flows, rapid runoff and other serious impacts," Mantua said.California sea lions will likely continue to struggle as the warm water temperatures lead to shifts in prey, he said. Record numbers of starving sea lion pups stranded on Southern California beaches last winter and spring as their mothers had a harder time finding food near their rookeries in the Channel Islands.Investigations of the sea lion strandings by AFSC researcher Sharon Melin and others found that adult females could not maintain enough lactation to support normal pup growth. In July 2015 AFSC biologists recorded declines in the number of sea lion pups born on San Miguel and San Nicholas islands, another sign of nutritional stress in the population.Mantua noted that El Niño effects extend far beyond the West Coast of North America. Dry conditions in Central America have already led to restrictions on the size of ships that can transit the Panama Canal because of lack of water, for instance. Meanwhile heavy rains are falling in the Peruvian desert."This El Niño will likely cause extreme climate events in different parts of the world for the next six to nine months," Mantua said.
How science tracks conditions
The way that El Niño interacts with the warm blob may depend on the depth and extent of the blob's warm water, which remains something of a mystery, said Toby Garfield, director of the SWFSC's Environmental Research Division. If it's shallow, it should dissipate quickly. But if it's deeper, the larger volume of water may hang on longer."How much heat does it hold and how that volume of hot water out there may or may not change things, those are the questions everyone's asking right now," Garfield said. "This is going to be a very interesting winter coming up and many scientists and communities will be working hard to anticipate and prepare for changes in the ocean and atmosphere."Marine scientist are mobilizing partnerships to make the most of ocean monitoring instruments along the West Coast. New instruments such as autonomous gliders that survey ocean conditions may offer opportunities to gather marine data that was not available during previous El Niños, Garfield said.

Rare Giant Squid Found Off the Coast of Hawaii
A fishing charter off the coast of Hawaii encountered a rare and beautiful sea creature this week: a 7-foot-long giant squid. The creature was dead, floating motionless with the bulb of its head sticking out of the water.
"It was a fishing charter and we had just released a blue marlin. We were just getting the line set back out and my guest actually said, 'Hey, what is that floating over there?' We got closer to investigate...as we got close I realized it was a giant squid. It was already on the surface. In Hawaii, we have extremely clear water. We could see his entire body," explains boat captain Cyrus Widhalm of Kona Sea Adventures.
This is the first time in Widhalm's 10-year boating career that he has seen such a creature. He was fishing in extremely deep water when they made the discovery, he says.
Once they were close to the squid, Widhalm called a local marine biologist who recommended the crew pull it on board and bring it back to land if it was, in fact, dead. Widhalm and his crew then had to carefully check that the squid was deceased.
"It appeared dead but we weren't totally sure. My deck hand and I, Manny Billegas II, we reached out over the side of the boat. We didn't realize how heavy it was. I held him in place as he reached down to get it because we were worried a tentacle would reach out to grab him. Once we were sure it was dead, I got into the water. I pushed it up and he pulled it out," Widhalm tells Newsweek.
Because of the squid's size, the entire crew became involved in getting it on shore: Ian MacKelvie, also a deckhand, and anglers Mathew and Miriam Fowler helped out."I have a 36-foot boat and it took up quite a bit of space. They're very gelatinous so they can compress into a small space or really flatten out," says Widhalm. "My guests were blown away. Everyone was having a lot of fun at that point."
The boat traveled back to a dock in Kailua-Kona and the squid was pulled onto dry land. It was laid on a 72-inch fishing bag and exceeded the size of the bag, leading Widhalm to estimate the squid is at least seven feet long. "It might be the biggest one of that species ever found. There had been another brought in that was half the size," he says.

The squid was also weighted, coming in at 52.7 pounds. Afterward, it was placed on ice to prepare it for a long journey to Washington state, where researchers will examine the rare find. The marine biologist Widhalm consulted on the boat said he believes the squid to be a Megalocranchia fisheri.In addition to being beautiful sea creatures, squid are rather delicious. When asked if Widhalm considered saving it for dinner, he laughed: "They are edible but it seems like it would better serve as a research tool."

Global Fisheries Scientists set up 'Truth Squad' to Counter Inaccurate Scientific Claims in Media

Their media partners lap up stories of doom and collapse, often uncritically. For that reason, a group of International experts in fisheries management have come together as part of a new initiative, called CFOOD (Collaborative for Food from Our Oceans Data.) The coalition will gather data from around the world and maintain fisheries databases while ensuring seafood sustainability discussions in the media reflect ground-truth science.The scientists behind the project have long pushed for accurate and clean data sources on the world's fisheries.The CFOOD project, headquartered at the University of Washington’s School of Aquatic and Fishery Sciences (SAFS), is made up of a network of scientists whose mission stemmed from a frustration with erroneous and agenda-driven stories about fisheries sustainability in the media. The CFOOD project will maintain a website and social media channels that provide a forum for immediate feedback on new seafood sustainability reports and studies.“The CFOOD website allows us to offer independent scientific commentary to debunk false claims, support responsible science, or introduce new issues based on recent research,” said Dr. Ray Hilborn, Professor at University of Washington’s SAFS and founder of the CFOOD initiative.“The ocean is a remarkably abundant source of healthy protein,” said Hilborn. “And while sustainability challenges exist, particularly in areas lacking sufficient fishery management infrastructure, many fisheries around the world are well-managed and sustainable. The message doesn’t always seem to resonate with consumers because of misinformation they continue to hear in the media.”By reviewing and providing scientific analysis on relevant studies, papers, and media reports the CFOOD network hopes to use science to set the record straight for consumers, so they can have confidence the seafood they purchase is harvested in an environmentally responsible fashion.Other scientists on the editorial board for CFOOD include Robert Arlinghaus, Leibniz-Institute of Freshwater Ecology and Inland Fisheries and Humboldt at Universität zu Berlin; Kevern Cochrane, FAO Retired, Cape Town, South Africa; Stephen Hall, World Fish Center, Penang, Malaysia; Olaf Jensen, Rutgers University; Michel Kaiser, Bangor University, UK; Ana Parma, CONICET Puerto Madryn, Argentina; Tony Smith, Hobart, Australia; Nobuyuki Yagi, Tokyo University.“Exaggerated claims of impending ecological disaster might grab attention, but they risk distorting effort and resources away from more critical issues. I hope this initiative will help provide the balance we need,” said Dr. Stephen Hall, Director General, World Fish Center, based in Malaysia.The first set of comments on the CFOOD website debunks a WWF paper claiming a 74% decline in global mackerel and tuna species. The scientists point out that the data used to support that conclusion is out of date, having not been updated since 2004, and that more robust data sources, such as the actual stock assessments of tuna and mackerel stocks around the world were not used by the WWF in creating their estimate. We explore the comments in depth in our related story.To connect with the scientists, you can use twitter, facebook, or their website.Website: Twitter: Facebook:

Dolphins, Pelagic Red Crab, Sun Fish Point to El Nino Coming to Northern California
The subjects of science are often witnessed through microscopes, tiny squiggly things writhing in a petri dish. But last week as a large research boat drifted through the Gulf of Farallones National Marine Sanctuary, science was getting scrutinized through binoculars and even the naked eye.
For the 12th year in a row, researchers from Point Blue Conservation Science, the Gulf of Farallones and Cordell Bank Marine Sanctuaries were spending 10 days on the ocean outside the Golden Gate Bridge taking a scientific snapshot of ocean life.
“Our goal is to understand how ocean conditions affect food for birds and whales,” said Jaime Jahncke of Point Blue.
Over several days the team collected krill samples, tested for signs of ocean acidification and attempted to lay eyes on as many critters as possible.
“Our sampling effort looks at birds, mammals, krills, boat activity ,” said Jan Roletto, research coordinator for Gulf of Farallones National Marine Sanctuary.
But this year’s gathering turned-up some unusual phenomenon, which scientists believe are signs of an El Nino year - which draws unusually warm waters to Northern California. For the first time in decades, scientists saw schools of hundreds of common dolphins which aren’t common to the Bay Area, but rather the typically warm waters of Southern California.
“It’s a sign the water is more warm than we normally see,” Roletto said. “And that’s a sign of El Nino."
Scientists have recorded large pockets of warm water along the West Coast over the last two years - which they’ve affectionally nicknamed “the blob.”
“This year has been particularly interesting,” Jahncke said. “The ocean has been really warm because of 'the blob.' ”
During an expedition earlier this summer, the scientists noted fewer krill in the ocean which in turn was driving humpback whales closer to shore near Half Moon Bay and Monterey to seek out fish.
“There are more whales visible from the mainland,” Roletto said. “That’s because that’s where the fish are being concentrated.”
In addition to dolphins, Roletto said the group spotted other typically warm water creatures venturing north. Sleepy-looking sun fish were seen basking in the waters. And the researchers’ nets pulled up a curious traveler — a small red pelagic crab that normally makes its home near Baja.
“The last time I personally saw in this region red pelagic crabs was in the 1983, 1984 El Nino,” Roletto said.
Roletto said the lack of krill and juvenile rockfish which are normally abundant along the coast was posing hardships on common murres which have been recently turning-up starving and dead on Northern California beaches. Roletto said the young birds count on juvenile rockfish to survive. She pointed out similar die-offs occurred in past El Nino years.
“That’s pretty extreme,” Roletto said, “pretty significant indicator that something is missing in the eco system.”
As part of the research, observers armed with binoculars lined the boat’s upper deck, calling out every bird and mammal along a set swath of ocean near the Farallon Islands. Sea lions, whales and even plain old seagulls became part of a moving record of the area’s life. The results are compared to previous years’ records to help paint a picture of the changing conditions.
“It’s really interesting because things change from day to day,” said Danielle Lipski of Cordell Bank Marine Sanctuary. “Sometimes we’ll see lots of whales and seabirds and in other areas we won’t.”
Jahncke stared off across the churning waters as the boat bobbed and jibed across rolling swells — when something suddenly caught his eye. In the distance came the telltale blowhole spout of a whale.
“Do you see it?” he said enthusiastically, quickly tapping record of the sighting into his computer. Then he leaned back to appreciate the view, watching as the ocean swallowed the meandering giant.
