Gritty wharf at Port of L.A. will become marine research center

On a recent weekday morning, Daniel Pondella strode along a century-old stretch of concrete pylons and shabby warehouses in San Pedro.

As kelp swayed in the waves and terns circled overheard, Pondella recalled an elementary school field trip he took 40 years ago to this gritty wharf known as City Dock 1: “That was the day I decided to become a marine biologist.”

Now, Pondella is involved in transforming the wharf into a marine research center at the heart of the Port of Los Angeles, the nation’s busiest.

When City Dock 1 opened in 1913, it turned on a spigot for the Southern California economy through which $283 billion a year in international commerce now flows. Plans call for it to be converted into a nexus of laboratories and classrooms, fish hatcheries and berths for research vessels, which will explore the flows of Pacific currents, solutions to oceanic pollution and coastal erosion, and the rhythms of sea creatures from bacteria to 150-ton blue whales.

Sperm as superfood? It’s a healthy snack for squid and other critters

Certain females consume male ejaculate and sperm as if they were food, using the nutrients to fuel their own bodies as well as their eggs, according to new research.

The study, published in the journal Biology Letters, adds yet another dimension to the battle between the sexes.

“If males have their sperm consumed, rather than used for egg fertilization, they will lose that reproductive opportunity. Therefore, it is in the male’s best interests to try to ensure at least some of his sperm reaches the female’s eggs,” lead author Benjamin Wegener, a researcher at Monash University’s School of Biological Sciences, explained to Discovery News.

Hurricane Sandy, Climate Change, and the Future of Fish

Brian Hajeski, 41, of Brick, New Jersey, reacts as he looks at debris of a home that washed up on to the Mantoloking Bridge the morning after Hurricane Sandy rolled through, Tuesday, October 30, 2012, in Mantoloking, New Jersey.

Hurricane Sandy’s terrible toll in lost lives and decimated communities is still being measured. But as we start to sort out the pieces, it’s also worth noting that the storm sent shockwaves through the mid-Atlantic region’s fishing industry. Harbors and infrastructure were pummeled and in some cases destroyed along the New York and New Jersey coastlines, and the Garden State Seafood Association has already asked Gov. Chris Christie (R-NJ) to formally request a federal fisheries disaster declaration.

In the aftermath of the storm, the link between our changing climate and increasingly extreme weather is coming into greater focus and being called out by an increasingly large caucus. (For more on the link between climate and extreme weather events in North America, see this new column by the Center for American Progress.) New York Gov. Andrew Cuomo was among the first to link Sandy’s fury to the “reality” of climate change. Bloomberg Businessweek ran a cover story under the banner headline, “It’s Global Warming, Stupid,” which called out the increasing spate of corporate voices accounting for climate change in their business models. And the magazine’s namesake, New York Mayor Michael Bloomberg, cited climate change as the tipping point that led to his much-ballyhooed endorsement of President Barack Obama for reelection.

Silvery fish bend a law of physics

Silvery fish such as herring, sardine and sprat are “breaking” the basic physics law of reflection, according to a study from the University of Bristol published this week in Nature Photonics.

Reflective surfaces polarize light, but PhD student Tom Jordan and his supervisors Professor Julian Partridge and Dr Nicholas Roberts in Bristol’s School of Biological Sciences have discovered that these silvery fish have defeated this basic law of reflection, which helps protect them from predators.

Until now, it was believed that the fish’s skin, which contains “multilayer” arrangements of reflective guanine crystals, would fully polarize light when reflected, thereby reducing reflectivity and making them more visible to predators.

Be happy! Eat more sardines!

As the days grow shorter, considering the role of omega-3s in keeping everything sunny

Seasonal Affective Disorder (SAD) was discovered by Dr. Norman Rosenthal after noticing that his own sluggish mood — first noticed after moving from sunny South Africa to New York — improved after exposing himself to bright light. SAD affects about 8 percent of people in wintry New Hampshire but less than 2 percent in Florida. Lack of sunlight may alter sleep-wake cycles by means of nerve signals from the eye to the brain’s biological clock (the suprachiasmatic nucleus) with the help of melatonin from the pea-sized pineal gland.

Although Iceland’s daylight diminishes, due to their near-arctic latitude, from over 9 hours on October 20 to just over 4 hours in December, its SAD prevalence of less than 4 percent is much lower than that of U.S. or European locations with equivalent levels of seasonal darkness. In fact, Icelanders are among the happiest people in the world — despite their 2008 financial crisis, volcanic eruptions, and the predominant winter darkness.

In addition to their helpful social support and encouragement of out-of-the-box lifestyles — the mayor of the city of Reykjavik, Jon Gnarr, who is also a comedian, as an example — Icelanders believe that their high consumption of ocean fish and fish oil helps them cope. Oil-rich cold-water fish like salmon, cod, and sardines, fish oil supplements, and some plant-based foods like walnuts contain omega-3 polyunsaturated fatty acids, which research on other mood disorders suggests have an antidepressant effect. We’ve known for quite a while that eating fish correlates negatively with major depressive disorder.

Fishery Management: An Analysis of Fish Stock Assessments

Center for American Progress

Counting Fish 101

An Analysis of Fish Stock Assessments

George Lapointe, Linda Mercer, and Michael Conathan   

Science is integral to fishing operations. Without the ability to estimate how many fish exist in the ocean there’s no way to determine how many of them we can catch while allowing the remaining fish populations to stay viable. But fish live in a mostly invisible world beneath the ocean surface, they move around constantly, and they eat each other.

This creates a dynamic population structure that’s incredibly difficult to track, making fish virtually impossible to count. Thus, fisheries scientists—like political pollsters or other statisticians—must rely on imperfect data to make their predictions about the status and health of fish populations.

They take these data—some of which they collect, some of which come from fishermen—and plug them into scientific models which, in turn, create estimates of population health. Because the entire population of a given species is frequently divided into subpopulations known as “stocks,” these estimates are called “stock assessments,” and they form the backbone of modern fishery management in the United States.

These assessments provide an estimate of the current state of a fish population and, in some cases, forecast future trends. This tells us whether fishery management goals are
being met and indicates the type of conditions to which the fishery will have to adapt in the near future. In an ideal world, scientists would have the resources to provide managers with updated stock assessments for each species every year, but their expense and complexity mean they can only be updated periodically.

Regardless of how frequently they can be updated, strong, science-based stock assessments are the key to future sustainability, not just of the fish but also of the fishing industry. Fishing is an inherently unstable business, yet strong, accurate science can give fishermen a better understanding of whether their resource will remain healthy, and if it does, how many fish they will be allowed to catch. This in turn allows fishermen to make informed business decisions and stabilizes coastal economies.

Sea Level’s Rise Focus of Summit

Projections of dramatic change draw group to UCSD to strategize about vulnerabilities of affected areas

LA JOLLA — Climate researchers, social scientists and policy experts from across the Pacific Rim convened at UC San Diego last week to get ahead of seas projected to rise so dramatically that they could create some of the most visible effects of global warming.

Representatives from about 20 leading research universities and nonprofit groups in South Korea, Russia, Indonesia and elsewhere met to prepare for potentially catastrophic effects on 200 million people and trillions of dollars of coastal assets.

Sea levels off most of California are expected to rise about 3 feet by 2100, according to recent projections by the National Research Council. Higher seas create challenges for port cities from San Diego to Singapore, including the potential for dramatically increased damage to coastal roads, homes and beaches — especially during storms.

“All future development has to be assessed in regards to future rises in sea level,” Steffen Lehmann, professor of sustainable design at the University of South Australia, said during the conference. “Reducing the vulnerabilities of urban (areas) is the big topic, the big task ahead of us now.”

Potential responses include managing a retreat from eroding bluffs and reshaping coastal areas to buffer development from higher water levels. “The missing link (is) between the science and those guys in planning offices and architecture firms and city municipal offices,” Lehmann said.

David Woodruff, director of the University of California San Diego’s Sustainability Solutions Institute, organized the workshop to address that problem with cross-disciplinary discussions that move toward international action.

“We are trying to affect societal change,” he said. “The sooner we start scoping options, the less expensive it will be to save current infrastructure.”

The workshop was sponsored by the Association of Pacific Rim Universities, a consortium of 42 leading research institutions. Participants drafted a report about rising sea levels for top university leaders so they can make the topic a priority with national-level leaders around the Pacific Rim.

“I really think universities can play a key role,” said UC San Diego’s Charles Kennel. “They are right at the pivot point between connecting knowledge to action. … One of the places they need to transfer their knowledge to is adaptation to climate change.”

A warming climate causes sea levels to rise primarily by heating the oceans — which causes the water to expand — and by melting land ice, which drains water to the ocean. Sea levels at any given spot depend on a complex interaction of factors, such as ocean and atmospheric circulation patterns and tectonic plate movements.

Global sea level has risen about 7 inches during the 20th century, the National Research Council said.

While sea-level-rise projections aren’t a sure thing, they are widely accepted by mainstream scientists. Skeptics see it as a waste of money to plan for problems that may not materialize for decades, or may be more modest than predicted.

New NOAA Ship Strengthens Ties between Scripps Oceanography and Southwest Fisheries Science Center

Collaborations between La Jolla institutions began more than 70 years ago and flourish today with a mix of strategic relationships Scripps Institution of Oceanography/University of California, San Diego

NOAA anticipates bringing the Reuben Lasker to the West Coast in 2013 and beginning operations in 2014. The ship will support scientific assessments of fish stocks and other marine life on the U.S. West Coast.

“Reuben Lasker represents an important investment by the American people in our ability to monitor the health of our ocean ecosystems,” said Bruce Appelgate, associate director of ship operations and marine technical support at Scripps. “This process of investment must continue in order to revitalize the United States research fleet, so that societally important issues can be properly understood.”

The new vessel honors the late Reuben Lasker, a pioneering fisheries biologist who served as director of SWFSC’s coastal fisheries division and worked in a key position as an adjunct professor at Scripps. Lasker fostered fundamental collaborations that formed a scientific bridge between Scripps and SWFSC.

“Reuben Lasker was arguably the father of West Coast fisheries oceanography,” said Dave Checkley, a Scripps professor of oceanography and director of the Cooperative Institute on Marine Ecosystems and Climate (CIMEC), a Scripps-led NOAA program established to study climate change and coastal ecosystems. “He brought his basic knowledge of insect biology to bear on plankton and fish, and combined this with oceanography to lead the Southwest Fisheries Science Center’s program on small pelagic fish, particularly anchovy and sardine.”

“He and his colleagues are renowned worldwide for their contributions to the biology of these fish and their ecology and fisheries oceanography. He, as much as anyone, fostered the close and productive collaboration between academia and fisheries.”

Checkley, who noted that Reuben Lasker served on his Ph.D. committee, said the namesake vessel furthers the close collaborations between Scripps and NOAA in fisheries oceanography that was formalized in 1949, following the collapse of California’s sardine fishery and the inception of the California Cooperative Oceanic Fisheries Investigations (CalCOFI) program, a unique partnership of the California Department of Fish and Game, NOAA Fisheries Service, and Scripps. CalCOFI stands as one of the world’s longest and most important marine monitoring programs and has provided valuable insights about various aspects of the waters off California and its inhabitants for more than 50 years.

“The Reuben Lasker will be one of NOAA’s state-of-the-art fisheries vessels and will not only enable the continuation of CalCOFI but enhance it with its superior capabilities,” said Checkley.

Record Salmon Run Expected

“The Klamath River expects a record chinook salmon run this year, the most since 1978. Much like the abundant forage – such as sardines and squid – that live off California’s coast, the high numbers of salmon reflect both strong precautionary fishery management practices and good ocean conditions.

Epic forecast for fall run on Klamath River

Written by Adam Spencer, The Triplicate

The largest projected return of fall-run chinook salmon since 1978 is looming over the Klamath River.

Fishery managers project that roughly 380,000 adult chinook salmon  will migrate up the Klamath this fall to spawn — three times the estimated run of 2011 adult chinook and 50 percent greater than the highest run on record (245,242 total fish in 1995).

Starting Wednesday, sport fishermen will be allowed to keep four adult chinooks per day, with a possession limit of eight adult chinooks.

The abundant forecast is a boon for sport anglers, tribal fishermen and the guides, hotels and restaurants that benefit from tourism dollars.

“I think it’s going to be the best season I’ve ever seen,” said fishing guide Gary Hix, who has already booked up much of his season on the Klamath.

“We haven’t had a four-fish quota since the quota era started,” said Wade Sinnen, senior environmental scientist with the California Department of Fish and Game.

Sinnen said it was a “tough sell” to convince the California Fish and Game Commission to adopt the four-fish limit, but the projections warrant it. “Even with a four-fish adult bag, it’s very unlikely we will obtain our quota,” he said. “This is a test year to evaluate the capacity of the sport fishery.”

It’s important to get as close as possible to the sport-fishing quota of 67,600 chinooks, because conditions are ripe for another event like the 2002 fish kill when tens of thousands of salmon died from diseases before spawning — partly due to more fish than usual.

An estimated 34,000 to 78,000 salmon died primarily from a gill-rotting disease known as “ich” (Ichthyopthirius multifilis).

“I was out there counting those dead fish; it was a smelly, disgusting mess — it was sad really,” Sinnen said. “People are nervous this year that the same thing could occur due to the record forecast of salmon and dry to average water conditions in the Klamath basin.”

To prevent a repeat fish kill, the Bureau of Reclamation started releasing additional water from the Lewiston Dam on the Trinity River to keep the flow of the lower Klamath River at 3,200 cubic feet per second throughout the peak of the fall run.

Mike Belchik, senior fisheries biologist for the Yurok Tribe, presented a case for higher flows for the fall-run chinook to the multi-agency Trinity River Fall Flows Workgroup, which was well received.

Maintaining a minimum flow of 2,800 cfs for an above-average run had already been established, but this run’s bigger than that.

Belchik emphasized to the group that excellent salmon fishing on the ocean provided reason to trust the predictions, and “in order to decrease the odds of fish kill happening we would like to increase the flow from 2,800 to 3,200,” he said.
