Image 1 - Changing Environmental Conditions And Predators Affect Survival Of Atlantic Salmon In The Gulf Of Maine
2011-11-19 04:28:27

Stocks of  Atlantic salmon (Salmo salar), which have been steadily declining for the past few decades, are facing  new challenges in the Gulf of Maine, where changing spring wind patterns, warming sea surface temperatures and new predators along altered migration routes are affecting their survival. In a paper published online in the journal Fisheries Management and Ecology, Kevin Friedland and co-authors suggest post-smolts are entering an increasingly warmer coastal ocean,...

EZ Pass for Fish Helps Ocean Tracking Network Locate Salmon from Maine off Halifax, Nova Scotia For years scientists have struggled to understand the decline and slow recovery of Atlantic salmon, a once abundant and highly prized game and food fish native to New England rivers. Biologists agree that poor marine survival is affecting salmon in the U.S. and Canada, but specific causes are difficult to determine in the ocean. Small acoustic tags and associated technology may provide some...

Surprises Found in Environments Just Miles Apart From the surface, the two areas of ocean off the coasts of northern New Jersey and Long Island, New York look the same. But to NOAA scientists, the four-square-mile patches could not be more different as they view real-time underwater images and environmental data to try to figure out what lives there and how climate change is affecting marine life, especially very young fish. "These areas are much more dynamic than terrestrial landscapes and...

Reducing bycatch could save millions of animals, reduce fishing costsSharks in captivity avoid metals that react with seawater to produce an electric field, a behavior that may help fishery biologists develop a strategy to reduce the bycatch of sharks in longline gear.  Shark bycatch is an increasing priority worldwide given diminished populations of many shark species, and because sharks compete with target species for baited lines, reducing fishing efficiency and increasing operating...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
