Water commission wary of Delta plan
Water commission wary of Delta plan
Chico Enterprise-Record
By Heather Hacking
February 8, 2010A conservation plan for the Sacramento-San Joaquin Delta, including plans for a system of tunnels and/or canals to bypass the estuary, raised questions from the Butte County Water Commission last week.
Paul Marshall, operations and planning manager for the Department of Water Resources, mapped out the current status of the Bay Delta Conservation Plan.Read more...

Columbia River salmon runs plentiful now, but...
The Oregonian
By Matthew Preusch
February 7, 2010In some Northwest streams, it seems like a return to the storied days when it was said salmon ran so thick you could walk across their backs.
Record numbers of coho have returned to the Columbia River in recent years, and this year forecasters predict the same for spring chinook. But it's not time to pop the champagne corks and declare victory in the nation's most expensive wildlife restoration venture.Read more...
Testing waters for salmon in San Joaquin River
Testing waters for salmon in San Joaquin River
The San Francisco Chronicle
By Peter Fimrite
February 7, 2010Water has begun flowing down 64 barren miles of the San Joaquin River in what is being touted as California's most ambitious effort to bring back long-lost native salmon.
The floodgates of the colossal Friant Dam outside Fresno were opened last week so researchers can study how the water flows down California's second longest river.Read more...
Recreational fishing in federal waters
Recreational fishing in federal waters
Honolulu Advertiser

February 3, 2010Many of the estimated 192,000 Hawai'i residents who fish in federal waters for food or sport are required to register under a new program aimed at learning more about the nation's recreational fish catch.
The requirement to sign up with the National Saltwater Angler Registry, which went into effect Jan. 1, affects recreational fishermen in Hawai'i because the state is one of 10 coastal states and territories that do not have a marine recreational fishing license.Read more...
Sardine industry banking on warmer seas

Business World

February 1, 2010While most businesses in the agriculture sector are bracing for the negative impact of El Niño this year, the Fishery bureau and the sardine industry are banking on the warmer seas in the western Pacific Ocean to bring in more catch.
"We were given the task by our central office to monitor this event," Ahadulla S. Sajili, director of the Fisheries Resource Management Program of the Bureau of Fisheries and Aquatic Resources (BFAR), said in an interview yesterday.Read more...
Playing Now: "Return of the Vanished Red Snappers"
Playing Now: "Return of the Vanished Red Snappers"
Florida Sportsman
January 31, 2010That could be the title of our federal fisheries managers' first science fiction production.
Like a magician pulling a rabbit out of his tophat, the NOAA Fisheries Service has discovered some four million pounds of Gulf red snapper that seem to have appeared out of nowhere.
Suddenly, the supposed overfishing which curtailed red snapper fishing trips is ended, according to a new assessment update hurriedly conducted in the face of huge protests (and U.S. Senator Richard Shelby's showing of outrage).Read more...
Nine-spined sticklebacks outsmart the competition
Nine-spined sticklebacks outsmart the competition
The Varcity
by Pallavi Hariharan
February 4, 2010Human culture becomes more complex by building on previously established advances. This type of societal evolution was once thought to be a feature unique to human society, but research indicates we are merely examples of a larger phenomenon.
For many organisms it is important to develop learning strategies to compete with predators. Some species learn by observing the behaviours of others, while others rely solely on personal experience. Complex discriminatory learning mechanisms involving memory and strategy were originally considered a hallmark of advanced human behavior.Read more...
Research finds water movements can shape fish evolution
Water movements can shape fish evolution
PhysOrg
February 4, 2010Catch a glimpse of a fish's body shape, and you can often guess how speedy it is. Tuna and mackerel look as if they should outpace frilly reef fish and eels. But how have all of these diverse body shapes evolved? Have fish bodies been shaped by the hydrodynamics of their environment or did they evolve for other reasons?
Turning to computational fish for answers, professor Fotis Sotiropoulos, along with postdoctoral researcher Iman Borazjani, from the university's St. Anthony Falls Laboratory decided to race hybrid and realistic fish in a massive parallel computer cluster to find out what influence the aquatic environment has had on fish shapes and swimming techniques.Read more...
Benefit from high-flow experiment at Glen Canyon Dam
Benefit from high-flow experiment at Glen Canyon Dam

February 2, 2010Resources along the Colorado River in Glen Canyon National Recreation Area and Grand Canyon National Park generally benefited from a high-flow experiment conducted in March 2008 from Glen Canyon Dam, near Page, Ariz., according to research findings released today by the U.S. Geological Survey.
The 2008 experiment, designed to mimic natural pre-dam flooding, tested the ability of high flows to rebuild eroded Grand Canyon sandbars, create habitat for the endangered humpback chub, and benefit other resources such as archaeological sites, rainbow trout, aquatic food for fish, and riverside vegetation.Read more...
