Solving the Riddle of the Brown Trout

The debate over whether brown trout (Salmo trutta) constitute a single species or several may soon be resolved, following the completion of the brown trout reference genome. “The brown trout reference genome will enable scientists to sample and decode DNA from different populations and compare to the whole genome sequence, providing the data required to...

Do Salmon Make Decisions as a Group?

“A series of new studies suggests migrating salmon work together to find their way home—and get lost when there aren’t enough of them to make a decision.” Read more about the research findings in this article from Nancy Averett via Hakai Magazine.

Salmon Notebooks Reveal Past Bounty

For more than 3 decades, from 1912 to 1948, a government “fisheries overseer” named Robert Gibson and his colleagues filled dozens of notebooks with fish scales from the Skeena River. Now, scientists have used the DNA preserved in those scales to study changes in the fishery. “The conclusion is sobering: Declines have been more precipitous and...

Oldest Freshwater Fish Found

New age-dating techniques have revealed that one studied bigmouth buffalo fish lived to be around 112 years old. That's older than the species' previous estimated life expectancy of 26 years, and is the oldest known freshwater fish of any kind. The finding opened new avenues of question for conservation issues for the species as well. "The bigmouth buffalo...

Zombie Cicadas

Cicadas can be a popular fly pattern this time of year, and new research shines light on the interesting insects, examining a hallucinogenic fungus that causes them to operate in a zombie-like state. “We anticipate these discoveries will foster a renewed interest in early diverging fungi and their pharmacologically important secondary metabolites, which...

Innovative Technology Uses Fish Skin for Skin Grafts

Veterinarians at Michigan State University say they were able to save the life of a dog with significant burns thanks in part to an innovative technology that uses fish skin to help the body heal itself. "Fish skin has been explored as a skin substitute for people and animals in recent years. What makes it appealing is that, compared to skin grafts made...

Video Hatch: “How to Understand Tides”

In this video, Peter McLeod explains the basics of tides and how flats fishermen can utilize them to their advantage.

Fossil Provides Evidence of Fish Swimming in Unison

A team of researchers from Arizona State University along with a group from the Oishi Fossils Gallery of Mizuta Memorial Museum in Japan has found evidence of fish swimming in unison approximately 50 million years ago. “In their paper published in the journal Proceedings of the Royal Society B, the group describes their study of a slab of stone...

Video Hatch: “The Return of the Cutthroat”

In this film from Montana Fish, Wildlife & Parks, learn about the history of cutthroat trout in the state and their return to native ecosystems.

New Native Trout Challenge Kicks Off in 12 Western States

Anglers of all skill levels are invited to participate in the Western Native Trout Challenge, a program that incentivizes participants to catch native trout and char in each of the 12 Western states, and promotes support and awareness of conservation issues.
