El Nino predicted to return this year with implications for weather and fisheries

A warming of the central Pacific Ocean this year will change weather worldwide, US forecasters predict.

The warming, called an El Nino, can mean an even hotter year coming up and billions of dollars in losses for food crops.

Australia and South Africa should be dry while parts of South America become dry and parts become wet in an El Nino. Peru suffers the most, getting floods and poorer fishing.

But it could bring good news for some parts of the planet, leading to fewer Atlantic hurricanes and more rain next winter for drought-stricken California and southern US states. It could also bring and a milder winter for the frigid US north next year, meteorologists say

The National Oceanic Atmospheric and Administration issued an official El Nino watch today. An El Nino is a warming of the central Pacific once every few years, from a combination of wind and waves in the tropics. It shakes up climate around the world, changing rain and temperature patterns.

Has There Really Been A Sardine Crash?

Sardines have been a hot news topic in recent weeks. Environmental groups and others have claimed that the sardine population is collapsing like it did in the mid-1940s.

The environmental group Oceana has been arguing this point loudly in order to shut down the sardine fishery. That’s why they filed suit in federal court, which is now under appeal, challenging the current sardine management.

So what is the truth about the state of sardines? It’s much more complicated than environmentalists would lead you to believe. In fact, it’s inaccurate and disingenuous to compare today’s fishery management with the historic sardine fishery collapse that devastated Monterey’s Cannery Row.

Viewpoints: The state of sardine populations

Sardines have been a hot news topic in recent weeks. Environmental groups and others have trumpeted that the sardine population is collapsing like it did in the mid-1940s.

The environmental group Oceana has been arguing this point loudly in order to shut down the sardine fishery. That’s why it filed suit in federal court, in a case now under appeal, challenging the current sardine management.

So what is the truth about the state of sardines? It’s much more complicated than environmentalists would lead you to believe.

In fact, it’s inaccurate and disingenuous to compare today’s fishery management with the historic sardine fishery collapse that devastated Monterey’s Cannery Row.

In the 1940s and ’50s, the fishery harvest averaged 43 percent or more of the standing sardine stock. Plus, there was little regulatory oversight and no limit on the annual catch.

Today, the allowed annual U.S. catch totals roughly 5 percent and coastal sardine exploitation averages less than 15 percent of the northern stock.

Squid vs. fish: Camera captures epic undersea battle on video

Thanks to its sharp beak, a small red squid emerged victorious after an epic hourlong battle with a much bigger owlfish, all caught on video last November in Monterey Bay, Calif.

The black-eyed squid paralyzed the owlfish by cutting through the fish’s backbone, according to Bruce Robinson, a senior scientist at the Monterey Bay Aquarium Research Institute. Robinson narrates a video of the fight between invertebrate and vertebrate, captured by MBARI’s remotely operate vehicled Doc Ricketts on Nov. 11, 2013.

The Doc Ricketts discovered the struggling marine creatures at about 1,475 feet (450 meters) below Monterey Bay as the vehicle was rising toward the surface, said Susan von Thun, an MBARI senior research technician. Scientists watched the scene play out for 50 minutes before the ROV had to continue its journey, Von Thun told LiveScience. [See video of the squid-fish tussle.]

“They were sinking rapidly the whole time, and we think that’s part of the squid’s tactic,” Von Thun said. “We see a lot of feeding events, and oftentimes the squid gets startled and lets go, but this guy held on for the whole time that we watched it.”

By the time the ROV left, the squid and owlfish had dropped to a depth of 1,970 feet (600 meters), Von Thun said.

As sardines vanish from Southern California coastal waters, fishermen rely on squid and anchovy

Larry Derr was as prepared as any longtime Southern California bait fisherman for the disappearance of the Pacific sardines he has pulled up by the ton since the 1980s.

He can fish anchovies instead and, if those become scarce, there’s been a local surge in market squid to keep him in business.

But the fickle sardines have been so abundant for so many years – sometimes holding court as the most plentiful fish in coastal waters – that it was a shock when he couldn’t find one of the shiny silver- blue coastal fish all summer, even though this isn’t the first time they’ve vanished.

And the similar, but smaller, anchovies have proven a poor replacement since sardines became scarce. Fortunately, a boom in market squid has propelled Derr and other coastal pelagic fishers.

In three days of nighttime fishing last week, Derr barely cleared a measly 20 scoops of anchovies to sell.

“A couple days ago we caught a ton of anchovies,” Derr said, keeping a vigilant eye for the telltale red mass on the In-Seine’s sonar during a predawn hunt Saturday. The screen remained black with irregularly dispersed green dots representing schools too small to fish. “We want this to be solid red.”

Though sardines aren’t as valuable as tuna or rockfish, they’re an important food source for larger fish, marine mammals like sea lions, dolphins and whales, and sea birds that can spot them from the air and dive for them.

Some have attributed recent rashes of sea lion pup and pelican deaths to the sardine population decline, which began a few years ago and was officially recognized in December when the fishing quota was dropped to just 5,446 metric tons for all of California, Oregon and Washington from January to June. In the same time period last year, the quota was 18,073 metric tons.

The Pacific Fishery Management Council lowered the quota in November after years of sardine stock decline from 2006, when 1.4 million tons were estimated to be swimming around the north Pacific. This year, their numbers are believed to be less than 400,000 metric tons.

They’re back – the bay’s herring hordes return

Sea lions, porpoises and tens of thousands of birds are jockeying for position with fishermen this week as the annual herring run splashes into San Francisco Bay, a spectacular marine wildlife showcase that conservationists say is one of the largest in North America.

The schools of herring, which surge into the bay in several waves, have attracted as many as 70,000 birds to the region, particularly to Richardson Bay in Marin County, a spawning hot spot for the squiggling hordes.

The fish arrived en masse beginning last week to lay and fertilize eggs, or roe – a delicacy for a wide variety of species, including sushi-loving humans. Fishermen are rushing out every morning to cast their nets before the menagerie of honking, squawking ducks, pelicans and diving birds can devour all the good stuff.

“We’re the last predators to get a crack at those fish. Everyone else has come to the table, and we get the leftovers,” said Nick Sohrakoff, a herring fisherman and chairman of the local herring advisory committee. “There’s a lot of fish in the bay, and they seem this year to be a little bit bigger than they were in the past few years.”

The riotous reception is a good sign that the bay’s once-thriving herring runs, which collapsed four years ago, are returning to glory. The San Francisco run – the last urban fishery in the United States – is the only big-time fishing operation where spectators can actually sit on shore and watch commercial boats haul in the catch.

California fishers say quota system is all wet

The skipper of a fishing boat that has trawled Monterey Harbor for decades says he’s been docked since spring, unable to earn a living.

Jiri Nozicka says a federal quota system enacted to protect both fish and the commercial fishing industry has problems that he can’t navigate.

“How do I plan anything?” he asked, recently standing on the deck of the San Giovanni. “I can’t. It’s impossible.”

He’s not alone in criticizing the “catch shares” system and calling for changes. Commercial fishers, industry experts and government officials are among those who say that while fish populations are recovering, too few people in California are benefiting from that rebound in part because there aren’t enough qualified monitors to oversee the program.

“Financially, I can only say that multiple trips have been cancelled due to a lack of availability of these monitors, millions of pounds of fish have not been caught, processed and sold to markets and this is a loss of millions of dollars,” said Michael Lucas, president of North Coast Fisheries Inc., in a letter to federal regulators.

After Pacific Coast groundfish populations dropped dramatically in 2000 a federal economic disaster was declared, leading to the strict new quota system. The goal was to boost populations of black cod and dover sole and to revive the flagging industry.

Fishing Green: Calif. Harvested Wetfish Fisheries are the most efficient in the world

As more Californians consider their total carbon footprint, as a way to reduce human impacts on climate change, more are looking at “food miles”:  how far their food travels between the time it is harvested and the time it gets to their plate. The Farm-to-Fork movement not only implies freshness, but that transportation from the farm to the consumer’s plate is a relatively short distance.

Fishing, like farming, can be green and sustainable. And California is leading the way in this effort, but distance is a misleading measure. Fishing green implies that fisheries are harvested at a sustainable level, keeping the fish populations healthy, while providing nutritious foods to millions of Americans and others worldwide. Beyond fishing below set quotas, there are three ways that fishing green can be achieved:

• Reduce the harvest of foods that have high energy costs in their production, capture or transportation

• Reduce harvest of high trophic level species that require a large amount of primary production to replace their numbers

• Support efficiency in the production of fishery resources

In the complete “Fishing Green” report by Richard Parrish, PhD, you will learn more about how California’s wetfish fisheries (coastal pelagic species such as sardine, mackerel and market squid) are among the most sustainable methods of food production.  Purse-Seine fisheries for small pelagic fishes and squid in California are the most fuel-efficient of all the fisheries, averaging 6 gallons per metric ton harvested.

Time to Take Ocean Acidification Seriously?

    
November 22, 2013 — HUMANS, being a terrestrial species, are pleased to call their home “Earth”. A more honest name might be “Sea”, as more than seven-tenths of the planet’s surface is covered with salt water. Moreover, this water houses algae, bacteria (known as cyanobacteria) and plants that generate about half the oxygen in the atmosphere. And it also provides seafood—at least 15% of the protein eaten by 60% of the planet’s human population, an industry worth $218 billion a year. Its well-being is therefore of direct concern even to landlubbers.

That well-being, some fear, is under threat from the increasing amount of carbon dioxide in the atmosphere, a consequence of industrialisation. This concern is separate from anything caused by the role of CO2 as a climate-changing greenhouse gas. It is a result of the fact that CO2, when dissolved in water, creates an acid.

That matters, because many creatures which live in the ocean have shells or skeletons made of stuff that dissolves in acid. The more acidic the sea, the harder they have to work to keep their shells and skeletons intact. On the other hand, oceanic plants, cyanobacteria and algae, which use CO2 for photosynthesis, might rather like a world where more of that gas is dissolved in the water they live in—a gain, rather than a loss, to ocean productivity.

Helicopter ride reveals enormous mass of anchovies, herded by dolphins and whales

When small fish are threatened by large fish or much larger marine mammals in the open ocean, instinct demands that the small fish group together to try to appear larger as a group.

But it’s not often that one of these swirling bait balls contains perhaps millions of anchovies and is large enough to dwarf, by many times, some of the largest predators to roam the ocean.

Nor is it often that a photographer and videographer just happen to be flying overhead when one of these remarkable spectacles plays out.

The accompanying image was captured this week off Ventura, California, by Liz Vernand, who was a passenger with Channel Islands Helicopters.
