This Smart, Data-Collecting, Wave-Predicting Surfboard Will Save Our Oceans

It maps waves, predicts conditions, turns surfers into citizen scientists, and could be the data-collecting tool climate scientists need to study our rapidly acidifying oceans.


As the Internet of Things inches its way into every corner of our lives, no one would blame you for rolling your eyes at the suggestion that even a surfboard should be embedded with sensors and smartphone connectivity.

Don't. That surfboard is real. And it's helping scientists better understand the impact climate change is having on our oceans.

In 2010, Andrew Stern, a former professor of neurology at the University of Rochester who's now an environmental filmmaker and advocate, realized that surfers could serve as citizen scientists. Simply based on how much time they spend in the ocean, they could help collect data while on the water.

One of his filmmaker friends had recently met Benjamin Thompson, a surfer pursuing a PhD in structural engineering at the University of California, San Diego. Thompson was studying fluid-structure interactions, research that involved embedding sensors into boards. "It was mostly about tracking the performance of board," he says. Thompson's goal: to help the surfboard industry make better boards, and maybe use sensors to help surfers better understand (and improve) how they surf.

But after meeting Stern, Thompson realized he could use sensors as mini data loggers, collecting information about water chemistry as well as wave mechanics. He'd embed the electronics into a surfboard's fin. Thus the project, named Smartphin, was born.

"My intention with this was to use it as a tool to inform people about the environment and specifically the oceans," says Stern, who provided a home for Smartphin at the Lost Bird Project, his environmental filmmaking organization. "So I made a map with 17 surf spots around the world and said we'll deploy to these places as many sensors as the scientists say we'll need there [to collect] data."

Their original intent was to embed sensors to track water temperature, salinity (conductivity), and acidity, an important metric for climate scientists. Oceans have absorbed about a third of the carbon dioxide we've emitted since the dawn of the industrial age, making them around 25 percent more acidic than they were then. That lower pH (higher acidity) impedes the growth of calcium carbonate and is already harming shellfish fisheries and coral reefs. "But pH is hard to track, so we tackled temperature and conductivity first, and then planned on adding a pH sensor later," Stern explains.

Earlier this year, the team competed in a $2 million competition hosted by the Wendy Schmidt Ocean Health XPRIZE to inspire innovation of accurate, durable, and affordable pH sensors to help scientists better track and study ocean acidification. They suddenly found themselves not only in the running for the top prize but also in the company of a gaggle of climate scientists and technologists who could help Thompson design a pH sensor for the fin. Smartphin even made it all the way to the semi-finals, where it competed against teams of scientists from universities and research centers all over the world, before being eliminated before the final round.

Stern and Thompson are now looking for a way to get the Smartphin into surfers' quivers.

Though no formal agreements have been made, Intel is interested in joining the project to provide its chip and sensor acumen to the effort. And starting in November, the first Smartphin pilot project will begin, with 50 scientists and researchers from the Scripps Institution of Oceanography in San Diego screwing Smartphin prototypes into their boards and taking to the waters outside their workplace.

The scientists will compare the data—on water temperature, salinity, and acidity—that they collect from the Smartphins with data collected from the same types of sensors affixed to a pier, Stern explains.

Of course, to better understand acidification along coastlines, scientists need to collect as much data in as many places as possible. And that raises the question: How do you get millions of surfers to swap out their fins for Smartphins? And why would they buy a Smartphin if, say, a nonprofit couldn't cover the costs?

Thompson says he's built some extra technology into Smartphin that will compel surfers to use it for their own selfish reasons: To know where and when waves are good and to track their own surfing performance.

Motion sensors integrated into the fin will generate high-resolution tracking data that a smartphone app, which the fin communicates with via Bluetooth, will turn into reports similar to those surfers get from using the Trace sensor, Thompson asserts. Here's the real kicker: the fins will also collect wave characterization data, or what he calls wave signatures.

"In Southern California, from Point Conception to Tijuana, there are probably a dozen buoys in the water that characterize waves," says Thompson. These basically size the wave potential, based on the swells, and project that all the way to the shore. "And then Surfline says, 'This is what we think the waves are doing,'" he says.

But by culling data from sensors that are actually inside the waves and all around a break, Smartphin can generate a more accurate signature for the waves at any given time that people are surfing, says Thompson.

"A lot happens between the deep water and the break zone. You can use models to predict it but you don’t have the best [granularity]," he says, "We'll remove that by recording what is actually happening."

Declaration of Fisheries Closure Due to a Public Health Threat Caused by an Oil Spill Affecting Marine Waters

 notice

UPDATE: Declaration of Fisheries Closure Due to a Public Health Threat Caused by an Oil Spill Affecting Marine WatersOn May 19, 2015 a pipeline break occurred near Refugio State Beach in Santa Barbara County, affecting shorelines to the east and west. The initial statement estimated that 500 barrels of heavy crude oil was released and the responsible party has been identified as Plains All American.The Office of Environmental Health Hazard Assessment (OEHHA) was informed of this spill. OEHHA recommended that a fisheries closure be initiated. On May 19, 2015 a closure was issued, prohibiting the catch and consumption of finfish and shellfish in the area of the closure.

OEHHA has revised its recommendation regarding the  geographic boundaries of the closed area, and is advising that fishers avoid fishing in areas where there is visible sheen on the water. In consultation with OEHHA, the fishery closure area set on May 19, 2015 has been extended. The geographic boundaries of the closure include coastal areas from Canada de Alegeria at the western edge to Coal Oil Point at the eastern edge. The closure boundary includes the  shoreline and offshore areas between these points to 6 miles offshore. This closure is effective immediately. This closure prohibits the take of finfish and shellfish either from shorelines or from vessels on the water. An updated map is available online.

 

The official CDFW fisheries closure declaration is available online. For more information, please visit the CDFW Office of Spill Prevention and Response web page.

CDFW Closes Fishery Following Spill in Santa Barbara

notice

The California Department of Fish and Wildlife (CDFW) closed fishing and shellfish harvesting in Santa Barbara County from 1 mile west of Refugio State Beach to 1 mile east of the beach at the recommendation of the Office of Environmental Health Hazard Assessment (OEHHA) following the crude oil pipeline spill May 19.

The closure went into effect on May 19, 2015. It remains in place until OEHHA, part of the California Environmental Protection Agency, advises CDFW that it is safe for fishing to resume. Land markers for the closure are near the intersection of Highway 101 and Calle Real Road (west) to near the intersection of Highway 101 and Venadito Canyon Road (east). OEHHA also advises that anglers avoid fishing in areas where there is visible sheen on the water.


The United States Coast Guard and CDFW responded to the initial report of 21,000 gallon spill. The source was secured, but an unknown amount reached the Pacific Ocean.


Clean up operations and investigation into the incident is ongoing. The Oiled Wildlife Care Network has activated recovery teams to collect oiled animals. Anyone seeing oiled wildlife should report it to 1-877-UCD-OWCN (877-823-6926).

Drought-Stricken California Organizes Unprecedented Effort to Truck Hatchery Salmon to SF Bay

— Posted with permission of SEAFOODNEWS.COM. Please do not republish without their permission. —

Copyright © 2015 Seafoodnews.com

SEAFOODNEWS.COM [KCRA] May 19, 2015What do you do when you have 30 million young salmon ready for their big journeys downstream, but drought and development have dried your riverbeds to sauna rocks? In California this year, you give the fish a ride.State and federal wildlife agencies in California are deploying what they say is the biggest fish-lift in the state's history through this month, rolling out convoys of tanker trucks to transport a generation of hatchery salmon downstream to the San Francisco Bay. California is locked in its driest four-year stretch on record, making the river routes that the salmon normally take to the Pacific Ocean too warm and too shallow for them to survive."It's huge. This is a massive effort statewide on multiple systems," said Stafford Lehr, chief of fisheries for the California Department of Fish and Wildlife, which since February has been rolling out four to eight 35,000-gallon tanker trucks filled with baby salmon on their freeway-drive to freedom."We're going to unprecedented drought," Lehr said. "We're forced to extreme measures."Drought and heavy use of water by farms and cities have devastated key native fish in California. Last year, for example, 95 percent of the state's winter-run of Chinook salmon died. The fish is vital for California's fishing industries and for the food chain of wildlife.For the first time, all five big government hatcheries in California's Central Valley for fall-run Chinook California salmon - a species of concern under the federal Endangered Species Act - are going to truck their young, release-ready salmon down to the Bay, rather than release them into rivers to make the trip themselves.And California's wild native fish should pack a sandwich and something to read; they'll be spending a lot of the summer on the road too."Bone dry. Bone dry," said fish biologist Don Portz of the U.S. Bureau of Reclamation, who is six years into an effort to restore the southernmost salmon stream in the U.S., the Central Valley's San Joaquin River.Drought, a dam and heavy use of the river's water for irrigation have dried 60 miles of the San Joaquin. For the young salmon, whose life cycle for millions of years has involved travel from the river back and forth to the San Francisco Bay, that now means a 1 1/2-hour ride down California Highway 99 in a pickup-mounted fish tank."You give them that taxi ride down, they make it to the ocean, and come back" in a few years for trapping and a taxi ride back up to spawning grounds, Portz said.The rolling fish rescues occurring up and down the West Coast haven't always gone smoothly. In January, Oregon authorities charged a trucker with drunken driving after he hit a pole and flipped 11,000 juvenile salmon out on the roadway, where they died.For some of California's native fish, the rescue from drought often is by bucket, not truck.Near the town of Lagunitas, in Northern California's Marin County, watershed biologist Preston Brown stood ankle-high in a coastal tributary, searching for endangered California coastal Coho salmon and other, native fish. Decades ago, so many coho salmon filled the water that the noise of their jumping kept people in nearby houses up at night. On this day, Brown and his team find none.Starting in June, months earlier than usual because of the drought, Brown and others with local environment group Salmon Protection and Watershed Network, will search the waterway. In cooperation with wildlife agencies, they will try to rescue coho and other fish stuck in drying pools of water 4- or 5 inches deep.Sometimes, Brown said, the bucket brigades get there too late for the stranded salmon. "If they survived the raccoons" and other predators, "they dried up and died," Brown said.Lehr, the fisheries chief, expects some individual steelhead trout in Southern California will get truck rides two or three times this summer, as parts of rivers and creeks disappear.As a last resort, when some rivers have no pools of water left to shelter fish, wildlife officials will remove survivors to a hatchery to wait out the drought. Two such isolated native species from dried-up waterways have been living in government hatcheries since last year, snacking on flies that rangers catch in bug-zappers for them, Lehr said, and waiting for wetter times.

Fishermen, Businesses, and Fishing Organizations Support House Magnuson-Stevens Reauthorization Bill

savingseafood

WASHINGTON (Saving Seafood) - May 18, 2015

On Saturday, May 16, a diverse group of 20 businesses, 51 organizations, and 80 individuals representing fishermen and fishing communities from the East, West, and Gulf Coasts jointly signed a letter delivered to Congressman Rob Bishop (R-UT), the Chairman of the House Natural Resources Committee, supporting HR 1335, the "Strengthening Fishing Communities and Increasing Flexibility in Fisheries Management Act," which would reauthorize the Magnuson-Stevens Fishery Conservation and Management Act. The supporters of the reauthorization, which was authored by Alaska Congressman Don Young (R-AK), state that it will maintain the successful aspects of fisheries management under Magnuson-Stevens, while providing much-needed flexibility and economic relief to hard-working fishing communities.

According to the signatories of the letter, HR 1335 will "continue the rebuilding of depleted fish stocks, provide transparency, streamline the management process, and ensure that more scientific information is available to deal with data-poor fish stocks." This, the signatories contend, will strike the appropriate "balance" between addressing the ecological needs of fish stocks, the conservation goals of management, and the economic needs of fishing communities that are not being met by the current Act's rigid stock rebuilding requirements.The signatories of the letter are geographically diverse, representing the following states: Arizona, Alaska, California, Connecticut, Florida, Illinois, Maine, Massachusetts, Mississippi, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Rhode Island, Texas, Vermont, Virginia, and Washington. They represent many of the major fisheries and fishing regions of the United States, and while on the surface these groups may seem to have little in common, they are united in their desire to see reasonable reforms to the Magnuson-Stevens Act and additional flexibility brought to the management process.In addition to supporting greater flexibility in federal fisheries management, the letter also opposes attempts to transfer the management of the commercial red snapper fishery from the federal to the state level. This proposed change, supported largely by recreational fishing interests, would, according to the signatories of the letter, undermine the "process in place under existing law to deal with the complex issues surrounding this fishery."HR 1335 was approved by the House Natural Resources Committee on April 30, and will be considered by the House Rules Committee on Tuesday, May 19 at 3:00 PM. The full House is expected to vote on the bill sometime in the near future.View the letter to Natural Resources Committee Chairman Rob Bishop here —PDF (check your downloads).

'Substantial' El Nino event predicted

earth_graphic

The El Nino effect, which can drive droughts and flooding, is under way in the tropical Pacific, say scientists.

Australia's Bureau of Meteorology predicted that it could become a "substantial" event later in the year.The phenomenon arises from variations in ocean temperatures.The El Nino is still in its early stages, but has the potential to cause extreme weather around the world, according to forecasters.US scientists announced in April that El Nino had arrived, but it was described then as "weak".Australian scientists said models suggested it could strengthen from September onwards, but it was too early to determine with confidence how strong it could be."This is a proper El Nino effect, it's not a weak one," David Jones, manager of climate monitoring and prediction at the Bureau of Meteorology, told reporters."You know, there's always a little bit of doubt when it comes to intensity forecasts, but across the models as a whole we'd suggest that this will be quite a substantial El Nino event."

resultAftermath of flooding in California put down to El Nino

An El Nino comes along about every two to seven years as part of a natural cycle.

Every El Nino is different, and once one has started, models can predict how it might develop over the next six to nine months, with a reasonable level of accuracy.



How can we predict El Nino?

In the tropical Pacific Ocean, scientists operate a network of buoys that measure temperature, currents and winds. The data - and other information from satellites and meteorological observations - is fed into complex computer models designed to predict an El Nino. However, the models cannot predict the precise intensity or duration of an El Nino, or the areas likely to be affected, more than a few months ahead. Researchers are trying to improve their models and observational work to give more advance notice.



A strong El Nino five years ago was linked with poor monsoons in Southeast Asia, droughts in southern Australia, the Philippines and Ecuador, blizzards in the US, heatwaves in Brazil and extreme flooding in Mexico.

Another strong El Nino event was expected during last year's record-breaking temperatures, but failed to materialise.Prof Eric Guilyardi of the Department of Meteorology at the University of Reading said it would become clear in the summer whether this year might be different."The likelihood of El Nino is high but its eventual strength in the winter when it has its major impacts worldwide is still unknown," he said."We will know in the summer how strong it is going to be."

Weather patterns

The El Nino is a warming of the Pacific Ocean as part of a complex cycle linking atmosphere and ocean.The phenomenon is known to disrupt weather patterns around the world, and can bring wetter winters to the southwest US and droughts to northern Australia.The consequences of El Nino are much less clear for Europe and the UK.Research suggests that extreme El Nino events will become more likely as global temperatures rise.

La Jolla leaders discuss sea lion issue with NOAA

Lifeguards at La Jolla Cove trained in use of ‘crowding boards’ to deter pinnipeds

Sea_Lions_resting_2-19-15_t837The growing number of sea lions along the cliffs at La Jolla Cove is causing problems for businesses and beach-goers.

Last week lifeguards monitoring La Jolla Cove were given what could be the first of several tools in an arsenal to help manage the growing sea lion population at La Jolla Cove — training in the use of plywood “crowding boards.”The boards are used by SeaWorld personnel and others working in close proximity to marine mammals to help safely nudge the animals along and to get around them without being bitten. A regional stranding coordinator with NOAA Fisheries (Justin Viezbicke) provided the training, confirmed Chris Yates, assistant regional administrator of NOAA’s Protected Resources Division, West Coast Region.“It’s just largely a big plywood shield that keeps something between you and the animal,” Yates told La Jolla Light. “The lifeguards have to interact with sea lions on a fairly regular basis. … Crowding boards are a common practice for all sorts of different wildlife resource managers, but particularly with pinnipeds, to be able to protect themselves when they need to move animals from a place where they would be endangering themselves or people.”Crowding boards are just one method local governments such as the City of San Diego can use under section 109(h) of the Marine Mammal Protection Act (MMPA) to legally deter sea lions or other marine mammals from remaining in an area, including the use of water jets, sprinklers, air horns or other noise-making deterrents, strobe lights, starter pistols, electric livestock fencing, slingshots, cattle prods and rubber bullets.“If the city so chooses to exercise its authority under 109(h) of the MMPA, any city employee or contractor specified for that purpose can use crowding boards to move animals from places where they are either in danger themselves or where they have a public health or welfare implication,” Yates said.San Diego Lifeguard Lt. Rich Stropky referred questions about the training to a city spokesperson, who did not return e-mail and phone messages about the training by press time. A spokesperson for District 1 City Council president Sherri Lightner also did not return a message asking if Lightner would advocate for the use of sea lion deterrence allowed under the MMPA provision.The training came to light following a May 5 meeting Yates granted La Jolla Town Council (LJTC) president Steve Haskins and La Jolla Parks & Beaches (LJP&B) committee chair Dan Allen. Haskins and Allen requested the meeting, held at NOAA’s Southwest Region office in Long Beach, as a follow-up to LJTC’s April sea lion forum (bit.ly/sealionforum) and LJP&B’s directive that the city take action to address issues related to the sea lions’ growing presence (bit.ly/sealionsituation), such as public safety and the pervasive odor from their urine and excrement.

New_sea_lion_shenanigans_1_t837Tourists at La Jolla Cove snap photos of sea lions that have become bolder and more plentiful on the beach popular with swimmers.

“It’s pretty interesting what we found out,” Haskins said. “Some of the things I heard were not things I’ve heard before. … It seems like there’s something going on, on our end, where the people with the city aren’t tuning in to what’s being said. … Apparently this is a very bad situation that’s happening all over California, Oregon and Washington. The amount of sea lions has exploded and once they take over a place, they basically don’t give it up, so you need to move quickly if you want to change their behavior. You can’t take years to decide what to do.”Yates said several times he has reminded San Diego city officials of the measures available under the MMPA to legally harass sea lions without filing for permits or receiving NOAA or other authorization. “They’ve asked us at various times questions about 109(h) as it relates to … things going on during the years,” Yates said. “We’ve told them, yes, they have that authority under 190(h). … They don’t have to do anything with us. There’s no permitting. We don’t approve it, we don’t bless it, we don’t do anything. That’s their legal authority under the law.”Asked if any of the federally approved deterrent methods seem to work better than others, Yates replied, “That’s the million-dollar question.“In general, sea lions are very persistent,” he said. “They become habituated to these deterrent methods very quickly, and people up and down the California Coast are very frustrated because it’s not easy to keep them away from things that people want to keep them away from. In places where there are docks and marinas, the most effective methods have been physical structures that form barriers, but they’re strong, big animals that can jump and crush things, so when you’re building a barrier … or a fence, it’s a substantial thing.”Yates said most noise deterrents have not proven effective, as sea lions grow easily accustomed to them.“Some places use water effectively, but you have to consistently reinforce the animals,” he said. “If you don’t have a physical barrier that keeps them away from something you have to be very diligent in keeping them away from that spot, either physically crowding them off or using something like water or another technique that’s not going to hurt them — that’s part of the deal.”There is no magic formula to outfox the clever, dog-like creatures, Yates noted.“If you let them come back, they’ll be back in full force and you’ve got to start from square one, so it is a constant maintenance type of thing, which obviously puts a lot of resource strains on the city or government entities trying to do that.”Yates said the MMPA allows the city to effectively deputize a group such as the LJTC or LJP&B to manage deterrence methods. At Moss Landing in Monterey County — where it’s estimated sea lions cause about $100,000 in damage each year — people have been tasked with fulfilling community service requirements by chasing sea lions off the dock (in lieu of picking up roadside trash).“We’ve seen people hire contractors, we’ve seen people designate people as city representatives under that authority, even though they’re not official city employees or officials,” Yates said. “There’s a lot of room for creativity there, as long as those people are acting within the scope of what the law allows and the city is responsible for them. ...“I don’t know that that has ever been challenged in court … (but) I would think if a city documents for itself the need to exercise its authority under 109(h) and specifies the individuals who would be doing that activity, that that would likely work,” Yates added. “Each city or government entity has to kind of review that with their own eyes and their own legal (team) and their own comfort level as to how they exercise those rights.”While the roughly 70 to 100 sea lions at La Jolla Cove are not among the tens of thousands NOAA studies off the California coast, a city-commissioned study of La Jolla’s sea lion colony by marine mammal expert Doyle Hanan is ongoing. Results of the study should be released in the coming month and could help the city assess how to move forward with possible sea lion deterrent or behavior modification techniques.Unlike the harbor seals at Children’s Pool beach, NOAA said California sea lions almost exclusively breed and give birth in the Channel Islands, about 180 miles off the coast. Haskins said he and Allen would contact Lightner and the mayor’s office to share what they learned from NOAA and underscore the need to take immediate action. “The more we understand about the behavior and abilities of sea lions, the more it seems like it’s almost impossible to stop them,” Haskins said.Sea Lion UpdateSea lions breed and pups are weaned (so far) only on the Channel Islands. The breeding animals leave the mainland in May and return in August and September.* There are estimated to be 330,000 sea lions off the U.S. coast, with a 3-5 percent continuous growth rate since the 1970s. There is no theory to explain why many come at one time to mainland bluffs and beaches, such as La Jolla Cove.* Recent pup strandings are above normal and a phenomenon of perturbations in the food supply and not related to the perceived increase in animals at La Jolla Cove.* Elephant Seals and Guadalupe Fur Seals have been spotted on mainland beaches, and their population growth and habitat dynamics are like sea lions.* Sea lions explore new areas and haul out where they can be comfortable. Younger males learn dominant behavior from the older bulls.* The Maine Mammal Protection Act (MMPA) prohibits harassment of sea lions in any way by members of the public. However, harassment by city, county, state or federal personnel or their contractors is allowed under MMPA section 109(h).* Sea lions are quick learners and stubborn. The way to deter them from settling in any particular place is to make them uncomfortable. The recommended ways — all to be done together — are: physically approach and shove with a plywood shield, aka “crowding board”; make a loud noise, such as with an air horn; squirt high-pressure water on the animal’s nose, chest and or rear end.* Any effort must be a well-planned campaign, consistently done and started early in the day. The plan needs to address what to do next if moving the sea lions is successful, since the sea lions will relocate.* The problem will be worse if the animals feel comfortable spending the night in the location where they are a nuisance.* Predator sound reproduction has failed where tried.* Because sea lions can climb and/or jump as much as six feet, any fence to restrain them must be carefully engineered with spinning rungs. There is a potential problem with fencing trapping animals from returning to the sea.* Poop cleaning needs enzyme treatment. Water alone will not work.* Dogs and sea lions share vulnerability to the same kinds of diseases, so they must be kept away from each other.* Numerous locations along the California and Oregon coasts have conflicts with sea lions involving boat docks. Few have conflicts involving beaches and shoreline areas like La Jolla Cove does.* Presently there are no adopted guidelines interpreting MMPA section 109(h) for sea lion deterrence or removal.— Compiled from NOAA officials by

State and Federal Agencies Halt Commercial Sardine Fishing off California

Media Contacts:Kirk Lynn, CDFW Marine Region, (858) 546-7167Chelsea Protasio, CDFW Marine Region, (831) 649-2994Carrie Wilson, CDFW Communications, (831) 649-7191

State and Federal Agencies HaltCommercial Sardine Fishing off California

 

All large-volume commercial sardine fishing in state and federal waters off California has been prohibited as of Tuesday, April 28, 2015. The closing will remain in effect until at least July 2016.

"This may be an end of an era, but fortunately, the tough management decisions were made several years ago," noted Marci Yaremko, CDFW's representative to the Pacific Fishery Management Council (Council), and fishery manager for coastal pelagic species, including sardines.At its April 12 meeting, the Council recommended regulations that prohibit directed commercial fishing for Pacific sardine (Sardinops sagax) in California, Oregon and Washington for the upcoming fishing season, which would have begun July 1, 2015, and run through June 30, 2016. In light of revised stock biomass information and landings data for the current season, the Council also requested the National Marine Fisheries Service (NMFS) close the fishery in the current season as quickly as possible. This closure takes effect today."The stock is in a state of decline, and now is too low to support large-scale fishing," Yaremko explained. "Industry, government agencies and those looking out for non-consumptive interests have all worked together over the years to develop the harvest control rule we are using today, which defines when enough is enough."The Pacific sardine fishery in California was actively managed by the CDFW until 2000, when it was incorporated into the Council's Coastal Pelagic Species Fishery Management Plan. Since then, the fishery has been actively co-managed by the Council, NMFS, CDFW and Oregon and Washington's Fish and Wildlife agencies.California's historic sardine fishery began in the early 1900s, peaked in the late 1930s and then declined rapidly in the 1940s. A 20-year moratorium on the directed fishery was implemented in the late 1960s. In the 1990s, increased landings signaled the population's recovery. Numbers have since dropped again, significantly.The Pacific sardine fishery continues to be a significant part of California's economy at times. At the recent fishery's peak in 2007, 80,000 metric tons (mt) of Pacific sardine was landed resulting in an export value of more than $40 million. The majority of California commercial sardine landings occur in the ports of San Pedro/Terminal Island and Monterey/Moss Landing.The Pacific sardine resource is assessed annually, and the status information is used by the Council during its annual management and quota setting process. The Council adopted the 2015 stock assessment, including the biomass projection of 96,688 mt, as the best available science. Current harvest control rules prohibit large-volume sardine fishing when the biomass falls below 150,000 mt. The Council recommended a seasonal catch limit that allows for only incidental commercial landings and fish caught as live bait or recreationally during the 2015-16 season.The decrease in biomass has been attributed, in part, to changes in ocean temperatures, which has been negatively impacting the species' production. While the estimated population size is relatively low, the stock is not considered to be overfished. The early closure of the 2014-15 fishing season and the prohibition of directed fishing during the 2015-16 season are intended to help prevent the stock from entering an overfished state."Hard-working fishermen take pride in the precautionary fishery management that's been in place for more than a decade," said Diane Pleschner-Steele, Executive Director of the California Wetfish Producers Association. "Thankfully the Pacific Fishery Management Council recognized the need to maintain a small harvest of sardines caught incidentally in other coastal pelagic fisheries. A total prohibition on sardine fishing would curtail California's wetfish industry and seriously harm numerous harbors as well as the state's fishing economy."Pacific sardine is considered to be an important forage fish in the Pacific Ocean ecosystem and is also utilized recreationally and for live bait in small volumes. CDFW protects this resource by being an active participant in this co-management process. CDFW has representatives on the Council's advisory bodies, works closely with the industry to track Pacific sardine landings in California and runs a sampling program that collects biological information, such as size, sex and age of Pacific sardine and other coastal pelagic species that are landed in California's ports. These landings and biological data are used by CDFW in monitoring efforts and are also used by NMFS in annual stock assessments.For more information about Pacific sardine history, research and management in California, please visit CDFW's Pacific sardine webpage at www.dfg.ca.gov/marine/cpshms/
