Shrinkage of Humboldt squid puzzles scientists

A mysterious force has stunted the growth of Humboldt squid in the Sea of Cortez, and marine biologists suspect a change in the weather is to blame.

The ravenous animals normally weigh up to 30 pounds when they spawn at 12 to 18 months of age, but Stanford biologists have discovered a group of the squid that weigh only a pound apiece and spawn at less than 6 months old.

The rubbery animals with their long tentacles are a precious livelihood for Mexican commercial fishermen along the Gulf of California, and they’re a prized prey for gringo sportsmen.

But to William Gilly, a marine biologist at Stanford’s Hopkins Marine Station in Pacific Grove, they’re a scientific puzzle.

In a paper recently published in the journal Marine Ecology Progress, Gilly said he suspects the squid’s shrinkage was caused by the abrupt warming of the gulf’s water as a result of an El Niño that was detected during the 2009-10 winter.

The El Niño phenomenon, also known as the Southern Oscillation, occurs periodically when high surface air pressure over the Western Pacific pushes temperatures up throughout the tropical Eastern Pacific, including the Gulf of California, causing water temperatures to rise.

In September 2009, Gilly said, he and his colleagues cruised the Gulf of California, better known as the Sea of Cortez, and found abundant squid in their normal spawning grounds and their usual size.

“But in May, a year later, we couldn’t find any normal-sized squid in their normal spawning grounds,” he said. “Instead, the area was full of smaller squid – really small.”

A month later, Gilly said, the squid were still very small and spawning in what was formerly the normal spawning area for normal-size squid, while one group of full-size ones had migrated and were thriving 100 miles north around the gulf’s Midriff Islands.

“No one really understands the El Niño phenomenon,” Lilly said, “but it seems to be the best explanation – a change in the temperature is enough to change the total environment for squid or any other living organisms in the gulf.”

Rebuilding Fisheries: There’s an App for That

Mike Sweeney

Executive director, The Nature Conservancy – California

My daughter and I love to fish (on my iPhone). She’s 2; I’m a bit older, but we’re both excellent anglers (on my iPhone). Flick Fishing and Fishing Kings are our favorites. It’s no substitute for a father-daughter fishing trip, but there’s much less gear involved, and we never have to retie our lines. I’m keen on teaching her where her food comes from and never thinking fish comes from the grocery store. Catching things to eat is the world’s oldest profession, despite what they say about the other one. If you think about it, of everything we eat today, the only wild animals we still really hunt for food are fish.

The problem is that we’re getting too good at it.

That hunt is now going high tech in much bigger ways than my iPhone games. Off our California coast, environmentalists and fishermen have teamed up to use apps and iPads to not only find the right fish, but also to make sure we don’t catch them all. Keeping a stable population of fish healthy ensures there will be fish left to fish tomorrow. If you’re a commercial fisherman, you are required to record the number of fish you caught and where you caught them. Typically, you send all that data on hand-written logs into the federal fisheries agency and that’s the last you see of it. Enter eCatch, a new app developed by The Nature Conservancy and fishermen that lets them load their catch data at sea and have real time access to the latest information on where the fish are — the ones they want to catch and the ones they need to avoid.

Sharing information on what you caught and where is not the norm for fishermen. They tend to be the original rugged individualists and too often get caught in the race to catch more fish before the other guy does. The results of this have been bad for everyone: rapidly declining fish populations and fishermen going out of business. But a group of fishermen off our coast is trying to change the game by collaborating and sharing information.

Another Banner Year for Market Squid

By Danna Staaf

The California market squid fishery is about to be closed for the second time in its entire history.

That may sound bad, but it’s actually a sign of a booming business. The annual quota for market squid is 118,000 tonnes, a number so high that for years no one was sure it would ever be reached. But just last year, an abundance of squid led the fishery to be closed on December 17th, and this year it’s due to close a month earlier: November 18th.

It’s worth remembering that this fishery follows a boom-and-bust cycle, and the science behind the squid is poorly understood. Last year I interviewed two squid scientists (former co-workers of mine) for an article in the Monterey Weekly, and came away with this:

Clean Water Act failing in new climate

BY RYAN P. KELLY & MARGARET R. CALDWELL

The U.S. Environmental Protection Agency recently gave California some tough love in the form of a ghastly report card on water quality along our coasts and in our rivers and streams: The state’s water pollution seems to have gotten much worse, with the number of polluted water bodies skyrocketing between 2006 and 2010.

Some of this change is due to more aggressive testing; the blame for the rest is solely our own. And while this news is bad enough on its own, what’s often not discussed is that all of that polluted water ends up downstream in the coastal ocean, already hard hit by decades of abuse.

This is killing the goose that lays the golden state’s egg. Californians depend upon our coastal oceans more than you might realize. As of 2000, over three-quarters of Californians lived in coastal counties, and the state’s coastal economy accounted for $42.9 billion and 700,000 jobs. These numbers have surely risen since 2000, but we’ve failed to be the stewards of these waters that their value – economic, aesthetic and otherwise – deserve.

And the threats to ocean resources keep coming, from climate change to the collapse of so many fisheries stocks worldwide. One challenge we are just beginning to understand is ocean acidification, a consequence of the fact that the oceans absorb a large fraction of the carbon dioxide we continue to pump into the atmosphere. This has changed the chemistry of the entire world’s ocean, making it more acidic. Because this increased acidity dissolves the hard shells of many of the world’s marine creatures (e.g., oysters, mussels, and many forms of plankton), these creatures and the food webs of which they are a part face a difficult future.

The horrible air quality of the 1970s is an obvious analogy to the state of California’s waters today. While the state still has severe air quality problems in places – Bakersfield, the Central Valley, and the Los Angeles region stand out – three decades of concerted effort to clean up our air has led to significantly improved air quality for most of our state. And the benefits of such action are enormous: An EPA report earlier this year showed the direct benefits of the 1990 Clean Air Act Amendments dwarfed the costs of implementation by a 30-to-1 ratio. This month’s final EPA report on water quality only confirms what we already know, that California must do better when it comes to our coastal ocean.

Weather satellite budget cuts a ‘disaster in the making’ – Obama official

Jane Lubchenco, head of National Oceanic and Atmospheric Agency, criticises GOP moves to cut funding for critical satellite

Suzanne Goldenberg, US environment correspondent

America and Europe face a “disaster in the making” because of Congress budget cuts to a critical weather satellite, one of Barack Obama’s top science officials has warned.

The satellite crosses the Earth’s poles 14 times a day, monitoring the atmosphere, clouds, ice, vegetation, and oceans. It provides 90% of the information used by the National Weather Service, UK Met Office and other European agencies to predict severe storms up to seven days in advance.

But Republican budget-cutting measures would knock out that critical capacity by delaying the launch of the next generation of polar-orbiting satellites, said Jane Lubchenco, who heads the National Oceanic and Atmospheric Agency (Noaa).

“It is a disaster in the making. It’s an expression of the dysfunction in our system,” said Lubchenco, who was speaking at a dinner on the sidelines of the Society of Environmental Journalists meeting in Miami.

It would cost three to five times more to rebuild the project after a gap than to keep the funds flowing. “It’s insanity,” Lubchenco said.

2011 has set new records for extreme weather events in the US and around the world, bringing hurricanes, heatwaves, floods, tornadoes, blizzards, droughts and wildfires. Ten of those events, including last August’s devastating Hurricane Irene, inflicted damages of at least $1bn.

Climate change is expected to produce more extreme weather events in the future, making accurate long-range weather forecasts even more essential.

Growing chorus against catch shares

Written by

John Oswald | Staff Writer

A number of U.S. legislators are voicing their growing displeasure with NOAA’s catch shares program by asking the federal government to abandon the controversial fisheries management measure.

Simply, catch share programs take the total allowable catch for a fishery and divide it up into shares which are then bought by individuals, associations, communities or corporations. A main concern among those raising the cry against catch shares is that the policy consolidates the fishery in the hands of a few large operations to the detriment of individual fishermen.

On Oct. 6, Congressman John Runyan (R-NJ) sent a letter to President Obama urging him to reconsider the use of catch share programs for commercial and recreational fishermen. In his letter, which was also signed by Representatives Frank LoBiondo (R-NJ), Ileana Ros-Lehtinen (R-FL), Frank Guinta (R-NH), and Sandy Adams (R-FL), Runyan wrote,

“Excessive government regulations have played a large role in our continued economic crisis. One of these excessive regulations is the catch share programs for fishermen. These programs have proven to decrease the number of fishing boats, which can have long lasting unintended economic consequences, including the loss of jobs in the fishing industry.”

Less than a week later, U.S. Senators Kelly Ayotte (R-NH) and Scott Brown (R-MA) introduced the Saving Fishing Jobs Act of 2011 which would require, among other things, that the Secretary of Commerce terminate new and existing catch share programs that result in a 15 percent or more reduction in the total number of fishermen in the program.

“Catch share programs are driving New Hampshire’s fishermen out of business. Five months after federal catch shares were implemented in New England, 55 out of the initial 500 boats in the fishery controlled 61 percent of the revenue, and 253 of the boats were sitting at the dock, unable to fish without quota,” Sen. Ayotte said.

And as recently as Wednesday, an article in the Gloucester Times of Gloucester, Mass, reports that Sen. John Kerry (D-MA) has requested that NOAA administrator, Dr. Jane Lubchenco, declare the catch shares program a disaster.

All about Bayesian inference in fisheries science

​ICES Training Programme recently offered Introduction to Bayesian Inference in Fisheries Science, conducted by Ray Hilborn and Samu Mäntyniemi. It was attended by 26 students from 17 countries.

Ray Hilborn, one of today’s leading experts on fisheries, is a professor in the School of Aquatic and Fishery Sciences, University of Washington, specializing in natural resource management and conservation. He serves as an advisor to several international fisheries commissions and agencies as well as teaching graduate and undergraduate courses in conservation, fishery stock assessment, and risk analysis. He is author of Quantitative Fisheries Stock Assessment, with Carl Walters, and The Ecological Detective: Confronting Models with Data, with Marc Mangel.

What is Bayesian statistics?

Bayesian statistics is one variety of statistics. Depending on how you divide it, you could say there are three primary schools. Beginning statistics courses centre on the concept of the null hypothesis and whether the data support rejection of the null hypothesis; usually, statistics are reported so that the probability of the null hypothesis is false. Then, there is the probability that you can reject the null hypothesis, and that’s often called Frequentive statistics. Finally, there’s another school, the Likelihoodist, that deals primarily with the extent to which the data support competing hypotheses. It’s a more interesting statistic because it realizes that you often have multiple different hypotheses, which is interesting to the extent that the data support the different hypotheses.

Bayesian statistics is, in a sense, much like the Likelihoodist, but it goes the additional step of actually assigning probabilities to competing hypotheses. The reason that’s so important is that, when you are giving advice to decision-makers, they want to know what’s the chance that something will happen. It turns out that Bayesian statistics is the only form of statistics that philosophically claims that they are probabilities. Going back – I guess I first ran into Bayesian statistics about 35 years ago – you find that Bayesian statistics really dominated business schools because they were built around decision-making.
