Research models how deadly virus moves among Pacific salmon, trout
For the first time researchers studying a deadly virus modeled how it spreads to young trout and salmon in the waters of the Columbia River Basin, showing that migrating adult fish are the main source of exposure. The ecological modeling of the infectious hematopoietic necrosis virus, or IHNV, shows how it moves across the landscape over time, providing a crucial understanding for managers of hatchery programs attempting to protect juvenile salmon and trout. >click to read<15:24
Scaling back hatchery salmon could mean huge losses for fleet
Salmon hatcheries play a huge role in Alaska’s fishing industry. But what effect are all those hatchery salmon having on Alaska’s wild stocks, which are even more valuable? In Part 1 of this 2-part series, KCAW’s Stephanie Fischer looked at the Wild Hatchery Interaction Study, an 11-year project researching the genetic consequences of hatchery salmon straying into wild streams and cross-breeding with wild stocks. In this story, Fischer examines the economic consequences on the industry, should Alaska ever have to scale back its hatchery programs. click here to read the story 08:25
