Protecting South America’s Iconic Golden Dorado Fish

A new study launched last month by University of Massachusetts Amherst fisheries biologist Andy J. Danylchuk, in collaboration with Argentina’s Ministry of Environment and regional partners including Juramento Fly Fishing, Tigres del Rio, Fish Simply, and Patagonia Inc., is the first to assess the impact of catch-and-release fishing and other human and environmental pressures on the golden dorado, a fish of high economic and recreational value across South America.

Time is running out on their Indiegogo campaign to fund the much needed catch-and-release research.

Steelhead tags track mortality

Biologists are taking a unique opportunity to figure out why steelhead are dying.

They're implanting 100 juvenile steelhead with acoustic tags. That way they can track the fish as they migrate out to the ocean.

Steelhead Report

The National Oceanographic and Atmospheric Administration (NOAA) has published a report on the historic populations of steelhead in the Puget Sound.

The report identifies and describes fish based on genetics, life history, and geographical, hydrological and habitat characteristics. It will be used to develop a steelhead recovery plan for Puget Sound, which is expected in 2018.

2018? Apparently more work remains to be done before NOAA can announce their total failure to make any progress.

How fast can a salmon swim upstream to Idaho waters?

On average, an adult spring chinook takes about 18 days to swim 253 river miles from Bonneville Dam to Lower Granite dam, including passage over a total of four Columbia River dams and four more on the Snake River.

Lousy sockeye are lousy competitors

Recently published research indicates that juvenile Fraser River sockeye salmon that are highly infected with sea lice are 20 per cent less successful at consuming food than their lightly infected counterparts.

There's a fungus among us

Fisheries biologists have concluded conclude that a record high brown trout population contributed to the spread of the fungus that occurred on the Big Hole River in the fall of 2014.
