  • A virus found in farmed salmon populations may be to blame for sickness in wild salmon, states a study published in January in Virology Journal. “The authors warn that the presence of the virus, called infectious salmon anemia virus, could greatly increase the risk of devastating outbreaks for salmon fisheries from Alaska down to the Pacific Northwest,” writes Richard Conniff via TakePart.
  • Hydroelectric power plants, weirs, and waterfalls are known barriers for fish movement. Recently Swiss researchers investigated the positive impact fish ladders have on genetic exchange. Via Phys.org.
  • Twenty new species of freshwater fish were discovered in the remote Kimberley region of Western Australia. The finding boosts the total number of known species of fish in Australia by almost ten per cent. Via ScienceDaily.
  • Recently federal agencies, irrigation districts, and conservation groups agreed to a settlement that will provide opportunity for both fish and farmers to thrive in the Yellowstone River Basin. Via Switchboard, NRDC.
  • The Mill River in Connecticut boasts two protected habitat areas for native brook trout, but the fight to protect the species is ongoing. Laura Modlin writes about “Connecting with Native Trout,” in The Easton Courier.
