National Geographic Channel host Jakub Vâgner and his team employs HTI's high-tech acoustic telemetry to monitor movement of alligator gar and advance vital species research. Seattle, WA (PRWEB) May 05, 2011 Adventure angler, conservationist, and National Geographic Channel host Jakub Vâgner and his team set out in the wilds of the Trinity River to track an elusive Texas Titan, the alligator gar. In an effort to better understand and advance vital species research, the team put...

Tracking fish across Alaska's vast continental shelves can present a challenge to any scientist studying Alaska's seas. Researchers at the University of Alaska Fairbanks have successfully tested a possible solution in the form of underwater gliders. Last month, Peter Winsor, associate professor of physical oceanography, and Andrew Seitz, assistant professor of fisheries, tested the use of autonomous underwater vehicles, called gliders, for tracking tagged fish. Winsor and Seitz suspended...

Case study: Juvenile Salmon Acoustic Telemetry System detected 98 percent of tagged fish A new acoustic telemetry system tracks the migration of juvenile salmon using one-tenth as many fish as comparable methods, suggests a paper published in the January edition of the American Fisheries Society journal Fisheries. The paper also explains how the system is best suited for deep, fast-moving rivers and can detect fish movement in more places than other tracking methods. The Juvenile Salmon...

Temperature differences, slow water could delay ocean entry Temperature differences and slow-moving water at the confluence of the Clearwater and Snake rivers in Idaho might delay the migration of threatened juvenile salmon and allow them to grow larger before reaching the Pacific Ocean. A team of Northwest researchers are examining the unusual life cycle of the Clearwater's fall Chinook salmon to find out why some of them spend extra time in the cool Clearwater before braving the warm Snake....

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...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
