Can squid help make soldiers invisible?

Atlanta (CNN) — One of the world’s oldest organism groups, cephalopods, like squid, octopus and cuttlefish, have survived in Earth’s oceans for millions of years.

They key to their survival: mastering the art of camouflage.

Now, scientists say, these ancient invertebrates may hold the key to developing a combat technology that will allow soldiers to avoid infrared detection.

Researchers at the University of California, Irvine say they have discovered a way to use proteins in the cells of pencil squid to develop “invisibility stickers” that can be worn by ground troops.

“Soldiers wear uniforms with the familiar green and brown camouflage patterns to blend into foliage during the day, but under low light and at night, they’re still vulnerable to infrared detection,” said Alon Gorodetsky, assistant professor of chemical engineering and material sciences.

“You can draw inspiration from natural systems that have been perfected over millions of years, giving us ideas we might never have been able to come up with otherwise,” he said.

Gorodetsky and his team have focused on specialized squid cells known as iridocytes, which contain a unique light-reflecting protein called reflectin. They were able to engineer E. coli bacteria to synthesize reflectin and coat the protein onto a packing tape-like surface to create the “invisibility stickers.”

Researchers say these reflectin-coated stickers can be changed into virtually any color with a chemical or mechanical stimulus.

“There is a lot of flexibility in how one can deploy this material, essentially, by taking the stickers and putting them all over yourself, you could look one way under optical visualization and another way under active infrared visualization,” Gorodetsky said.

The lab technology is not ready to be used in combat zones as researchers work to develop an adaptive camouflage system, in which multiple stickers are able to work in sync and respond to varying infrared wavelengths.

“We’ve developed stickers for use as a thin, flexible layer of camo with the potential to take on a pattern that will better match the soldiers’ infrared reflectance to their background and hide them from active infrared visualization,” Gorodetsky said.

The researchers’ work was recently presented at the 2015 American Chemical Society national meeting.

Stanford Researchers Strap ‘Crittercam’ Onto Squid

Stanford Researchers Strap ‘Crittercam’ Onto Squid, Discover How They Speak, Hide Themselves

STANFORD (CBS SF) – Researchers at Stanford University strapped cameras on squid off the coast of Mexico and found the sea creatures likely use visual patterns to communicate and to hide themselves from predators, according to a study released this week.

Their study, published in the Journal of Experimental Biology, found Humboldt squid rapidly change their body colors from red to white to red again, in what researchers called “flashing.” They believe the behavior could be a way the squid speak with each other.

“The frequency and phase relationships [synchronization] between squid during flashing can be changed and this suggests that there is some information being conveyed that makes minute control over these details important to the squid,” Stanford researcher Hannah Rosen told the journal.

The researchers made their findings with the help of so-called “Crittercams” from National Geographic that were strapped onto the squid using Lycra-like “sweaters.”

Another behavior found by researchers is called “flickering,” where the squid produce waves of red and white across their bodies, likely to camouflage themselves from predators near the surface. They also observed what could be mating behavior of the squid.

Researchers plan to outfit more squid with cameras.

Northern California lands large share of state’s robust market squid catch

Published with permission of SEAFOODNEWS.COM

[Monterey Herald] By James Urton – December 8, 2014 –

The squid fishery in California remains robust, and this year’s catch has been unusually strong in Monterey Bay. In a typical season only about 20 percent of market squid are caught off Northern California. But this squid season — which runs from April to March — more than half of the state’s catch have come from north and central coast waters.

“We really had quite a banner year,” said Monterey harbormaster Stephen Scheiblauer.

By initial estimates, at least 75 percent of the Northern California squid catch came from waters in and around Monterey Bay. Scientists and squid fishermen do not fully understand the reason for this flip.

“For Monterey, it was amazing,” said Diane Pleschner-Steele, executive director of the California Wetfish Producers Association.

There have been other seasons where Northern California outshone Southern California in squid hauls. But, since 1980, all of those years have preceded or fallen during El Nino climate shifts, which bring warm water to the California coast, starting with Southern California and moving north. It’s believed squid follow the cooler water.

“These squid really respond to ocean conditions,” said Pleschner-Steele.

The state is not currently in an El Nino pattern. But, it is possible that recent El Nino-like shifts in ocean conditions drove market squid farther north.

“The last couple of years, especially in Northern California, have been good for squid,” said Neil Guglielmo, captain of the 70-foot fishing vessel Triumphal.

Since squid season began April 1, commercial boats have hauled nearly 60,000 tons of market squid through Northern California ports, with a dock value of approximately $38.3 million. This is the largest squid season north of Point Conception in history and more than double the previous record set in the 2002-03 season. This year, Eureka reported its first squid landings.

“We fished squid this year where we never fished before,” said Guglielmo.

For much of this season, Guglielmo took the Triumphal from its home port near Ventura up the coast to Monterey and points farther north to haul in squid. He reported squid as far north as Crescent City.

“We just followed them up there,” said Guglielmo. “There was so much squid.”

This season was also a record for Monterey Bay, with an estimated 45,000 tons of squid caught in its waters, according to marine biologist Briana Brady with the California Department of Fish and Wildlife.

These record hauls also bring welcome economic benefits to ports. The local squid industry supports approximately 1,500 seasonal and full-time jobs, according to Scheiblauer. Ten squid fishing boats are based in Moss Landing and Monterey. In addition to landing fees at wharfs and the dock value of catches, the squid season brings economic benefits in the form of room and board for crew, fuel for boats, ice, cold storage facilities, transportation and processing for each boat’s catch. The Monterey area includes three resident buyers for squid.

“They’re still a big part of our culture and economy,” Scheiblauer said.

Ample food supplies and undisturbed spawning grounds help sustain market squid along the California coast. But, based on past squid fishing seasons, their numbers can still fluctuate along 10- to 15-year cycles, according to Brady.

Market squid are relatively small, often measuring about a foot in length, and prefer to eat small invertebrates, plankton or each other. Their short six- to 10-month lifespan makes it difficult for biologists to estimate the size of the entire market squid population off California to manage the fishery sustainably.

Instead, beginning in the last decade, regulators crafted a squid fishery management policy around a handful of core regulations. No more than 118,000 tons of squid can be harvested in California waters during the annual season. This limit was based off annual squid harvests in the late 1990s and early 2000s.

“We’re happy with that maximum cap,” said Pleschner-Steele. “It’s a good, conservative number.”

The state also uses a limited-entry permit system for squid fishing to control the number of fishing boats in California waters. In addition, marine-protected areas in Southern California and Monterey Bay keep approximately one-third of squid spawning grounds along the coast off limits to fishing. Finally, no commercial vessel may fish for squid between noon Friday and noon Sunday. This weekly moratorium gives squid in non-protected areas opportunities to spawn, according to Scheiblauer.

As of Nov. 20, the statewide catch for market squid is nearly 115,000 tons. Since the maximum squid harvest cannot exceed 118,000 tons, this season is drawing to an early close. Under a voluntary co-management agreement between the squid fishing industry and Fish and Wildlife, larger fishing vessels ceased harvesting squid last month so smaller boats can “mop up” the remaining allotment of squid.

Based on reports from squid fishermen, this year there will still be plenty of squid left behind. But, in the wake of this season’s unusual squid bounty for Northern California, no one is willing to predict what might be in store for next year. In two previous El Nino cycles, desolate squid harvests in Northern California followed one or two years of largesse.

“You could have a boom year like this year and next year there’ll be nothing,” said Scheiblauer.

But, even after those turbulent oscillations, the squid fishery stabilized around a sustainable mean. That long-term trend gives others cause for cautious optimism.

“If the water doesn’t go crazy,” said Guglielmo, “I think we’ll be fine.”

Squid fishing in Monterey Ca. Lots of boats, lots of squid.

Jumbo squids attack Greenpeace submarine

The Greenpeace Dual Deep Diver.

A pair of Greenpeace submariners have had their own “20,000 Leagues Under the Sea” experience on an expedition in the Bering Sea — in a scaled down sort of way. Rather than the Nautilus and a giant squid, the pair were in a Dual Deep Worker submersible when the encounter occurred.

And their attackers weren’t a squid of the giant variety, but a pair of Humboldt squids, nicknamed “jumbo squid” or “red devil” for their famed aggression and the red colour the squids turn when in hunting or attack mode.

Although these squids can get pretty big — up to 1.9 metres (6.2 ft) in mantle length and up to 50 kg (100 lb) in weight, these guys are relatively titchy — no longer than a few feet in length, maximum. Their size, however, is no indication of courage: coloured a brilliant red, they have a brave go at the sub before swimming off in a puff of ink.

The Humboldt squid’s tentacle suckers are lined with tiny, sharp teeth that can do some serious damage, so the Greenpeace divers were lucky to be protected by the submarine — though there are some scientists who believe that the cephalopods aren’t usually aggressive, and might have been set off in the first place by flashing or bright lights like the one on the Dual Deep Worker.

Squid fishing debuts on North Coast

Posted:  09/11/2014 11:21 PM

Squid fishing boats docked in Eureka for the first time Thursday, unloading 124,000 pounds of squid at the Fisherman’s Terminal.

Commercial squid fishermen from Southern California were drawn to the North Coast by following squid that were driven out of their typical habitat by a rise in ocean water temperatures, said Jeff Huffman, Eureka dock manager with Wild Planet, who helped to facilitate the docking and unloading of the squid boats.

With few squid left in their typical fishing zones this year, Southern California Sea Food, Inc., has been moving up the coast. On Wednesday, two boats fished in the area between the mouth of the Mad River and the False Cape, south of the Eel River, bringing the first boat into the dock at 2 a.m. Thursday and the second at 7:30 a.m., Huffman said.

“The squid fishery has always been a Southern California fishery, but because of the  warm water down south the squid are all up here,” he said. “There have always been some squid here, but not in these numbers.”

Unusual patterns in the Pacific Ocean have shifted water temperatures, creating unusually warm water both to the north and south of California’s North Coast, said Eric Bjorkstedt, research fishery biologist with NOAA’s Southwest Fisheries Science Center and an adjunct professor in Humboldt State University’s fisheries biology department.

The temperatures have not grown warmer off the Northern California coast, which appears on National Oceanic and Atmospheric Administration maps that track water temperatures as one of the only places along the West Coast that does not appear dark red — the color that indicates warming waters.

While this is not a typical El Nino year, Bjorkstedt said some patterns are consistent with the weather phenomena’s conditions.

“Normally in an El Nino, market squid do very badly — usually the catches go nearly to zero,” he said. “The reproductive success is not high, and the squid industry basically crashes for that year.”

Squid populations could be shifting north because of a change in water temperatures or shifting closer to shore because they are following a shift in nutrients and food supply, said Jeffrey Abell, chairman of HSU’s oceanography department.

Shifts in weather patterns and climate causes water temperatures and ocean nutrients patterns to change, he said.

“It manifests the shifts in ocean circulation, which alters the input of nutrients into the ecosystem, and then the organism responds to that and moves into a range where it is not usually found,” Abell said.

Either way, there is an unprecedented number of squid off the North Coast, Huffman said.

Southern California Sea Food, Inc., hopes to bring in 300 tons of squid every 24 hours, and the squid is then transported in trucks to Monterey, where it is processed at a company plant, he said.

Huffman added the company is limited by the number of squid that they can process, unload and truck, but not by the amount of squid in the bay.

“I think they can definitely catch more than we can actually get through the place and shipped out,” he said.

By Sunday the company will have five boats in the area, and they are hoping to continuing fishing here for two to three weeks, Huffman said.

Having the fishermen in town will be a boost for the local economy, he said, as the crew of more than a dozen people stays in local hotels, eats, shops, buys fuel and pays for moorings at the marina.

“This is a great plus to the whole waterfront and the town,” Huffman said.

The goal of the Fisherman’s Terminal was to bring in this type of business, he said. The dock is typically used for processing crab, salmon and some other fish, but being able to unload squid there adds another avenue for profit.

“It is a unique opportunity for the city to use its loading dock. Normally this isn’t something that we get to do,” said Eureka Councilwoman Marian Brady.

“It is all money that is coming back into our economy,” she said. “We definitely need industry, and this is a form of commerce that uses our bay for its purpose. We built all this infrastructure, and it hasn’t been used optimally.”

The city is working on plans to get a cold storage facility in town to keep even more of the business local, she said. All the squid is currently being taken out of town to be processed.

“But these three to five ships that are in here, that is adding a spurt to our economy,” she said.

This is a positive development for the economy and the city, said Ken Bates of the Humboldt Fishermen’s Marketing Association.

“This activity at Fisherman’s Terminal is exactly the kind of thing we were hoping to see in Eureka when this facility was built,” he said. “It’s exciting.”

Monterey Wharf Walks: The Story of Squid

Amble out on a story-packed stroll, one that considers the town’s seafaring history.

| By Alysia Gray Painter |  Saturday, Aug 30, 2014  |

SQUID IN THE SPOTLIGHT: It’s sometimes difficult to narrow down what natural focus a town might have regarding the wildness that surrounds it. Sure, you could say that Klamath has strong ties to the redwoods and Big Sur to the condors, but most places snug against water or forest aren’t all that associated with a specific bit of nature above all others in the region. Monterey, though, is associated with quite a few. Whales, yes, otters, yes, sardines, yes, the Monterey Cypress, yes. And squid? We’ll wager that it is a rare day when the tentacled Pacific denizen tops otters and sardines in the list of “wildlife or natural wonders with Monterey cred,” but squidly creatures do have old connections to the Bay-close city. Squid fishing was once a prominent industry, and Monterey Bay Fisheries Historian Tim Thomas is considering it in all of its historic and fascinating context during two upcoming Wharf Walks. They’re set to set out on Saturday, Sept. 6 and Saturday, Oct. 4.

BUT SQUID-ORIENTED FACTS… aren’t the only thing on the table: calamari is, quite literally. Going with a “sea-to-table” theme, the Paluca Trattoria of Old Fisherman’s Wharf will serve Wharf Walk participants a “complimentary calamari appetizer” after the stories wrap. How often do we head out into a history-rich to-do only to end it with an edible related to the stories at hand? Not often enough. A bonus treat: Possible napping seals or sea lions off Finger Pier. Calamari, squid history, and snoozing seals? Yeah, that’s major Monterey cred right there.

TO FOLLOW… all of the upcoming Wharf Walks, keep an eye on the Fisherman’s Wharf page. And never fear, otters: You know you hold a special spot as the de facto fuzzy-faced ambassador of the M.B. area, but squids have played their role, too. Time to give them their briny due.

Monterey Bay – Squid Fishing – Thank You

Source: Monterey Harbor Update September 2014 –

The 2014 squid catch was an event of a life time! This years squid catch challenged the memory of local fisherman elders. They had a difficult time remembering a better year for the squid fishery going back to the 1960’s. This year more than 1500 jobs were created for local companies during this season. This years catch and subsequent use of the pumping and landing facilities along with the associated track trailers challenged the users of the commercial wharf with parking, transportation, and access. The businesses, fisherman, boaters, and the public worked within a defined amount of space. The limitations of commercial wharf II was challenged to try and be all things to all users on wharf II this year. We wanted to let you know how much we appreciate the wharf II users being patient throughout this busy 2014 season.

Thank you.

D.B. Pleschner: California’s ports, fishermen rely on healthy wetfish fisheries

Despite gloomy predictions of El Niño and the broader impact of climate change on the ocean and planet, California’s historic wetfish fisheries carry on — still the foundation of California’s fishing economy.

More than 150 years ago, Chinese fishermen rowed Monterey Bay at night in sampans, with baskets of burning fat pine on the bow used as torches to attract market squid, which fishermen harvested with round-haul nets.

This was the modest beginning of California’s “wetfish” industry. The immigrant Asian, Italian, Slavic and other nationalities of fishermen who came to America introduced new fishing methods. Around the turn of the 20th century, Sicilian immigrants to Monterey brought their lampara nets, another type of round-haul net, and launched what would become the largest fishery in the western hemisphere — California’s famed sardine industry, popularized in our collective conscience by John Steinbeck’s “Cannery Row.”

It was the plentiful schools of fish — especially sardines that stretch from the Gulf of California to Alaska — that provided opportunity for generations of enterprising fishing families to prosper. The complex of fisheries that makes up California’s wetfish industry, including mackerel and anchovy as well as squid and sardines, helped to build the ports of Monterey and San Pedro, as well as San Diego and San Francisco. Wetfish, now called coastal pelagic species (CPS), have contributed the lion’s share of California’s commercial catch since before the turn of the 20th century.

Even back then fishermen recognized that a sustainable fishery was good for both fisherman and fish. That’s why over the decades fishing interests have supported marine protections based on sound science and have contributed significantly to cooperative research. That tradition continues today.

In fact, today coastal pelagic fisheries in California like squid and sardines are managed with strict quotas as well as numerous time and area closures, including a statewide network of no-take marine reserves. Fishermen are allowed to harvest only a small percentage of the overall fish population. Current regulations require that at least 75 percent of CPS finfish must stay in the ocean to ensure a resilient core biomass, and the sardine protection rate is even higher at about 90 percent.

In addition, squid fishing is closed on weekends (squid live less than a year and die after spawning). And about 30 percent of squid spawning grounds are also closed in reserves.

What’s more, to preserve the quality of the catch, fishermen typically fish day trips near the ports. This makes California’s CPS fisheries among the most efficient and “greenest” fisheries on the planet with one of the lowest carbon footprints in the world. For example, wetfish fisheries can produce 2,000 pounds of protein for only six gallons of diesel fuel. This highlights the importance of California wetfish to California.

Beyond history, culture and sustainability, California’s CPS fisheries contribute essential revenue into local port communities. Wetfish fisheries are an important part of California’s fishing economy and squid is California’s most valuable fishery. Statewide, these fisheries represent more than 80 percent of all landings and close to 40 percent of dockside value of all fisheries in the Golden State!
