What is Troutnut.com?
Fly anglers live for the "hatches" when trout erupt in a feeding frenzy over the mass emergence aquatic insects from the river's surface. In these moments, trout can become so focused on one specific type of prey that they will pursue only a skillful imitation. Anglers who study aquatic insects to meet this challenge find that they're as captivating as the fish themselves. Every species has its own story, its own personality. We cross paths with these characters at the climax of a perennial drama of life and death, and--as with any great drama or sport--every play means so much more when we know the players inside and out. It's not just about catching fish. It's about knowing the stream and loving everything in it.

Troutnut.com's aquatic insect encyclopedia is a guide to these players and their stories. Read about the behavior of each species and view thousands of closeup photos, or join the fly fishing forum to meet other devotees of the world's healthiest addiction. You can learn the basics of mayflies, caddisflies, or stoneflies. Or dive into the details of storied species like the Hendrickson hatch and the Hex hatch.

New aquatic entomology book for the southeast US

By Troutnut on May 22nd, 2017, 11:58 am
A group of prominent aquatic entomologists, including longtime Troutnut forum member Dr. Luke Jacobus, have just released a new book, Larvae of the Southeastern USA Mayfly, Stonefly, and Caddisfly Species. It's edited by John C. Morse, W. Patrick McCafferty, Bill P. Stark, and Luke M. Jacobus.

Luke sent me this description for anglers:

Whether your flies are wet or dry, identifying larvae of mayflies, stoneflies, and caddisflies can be helpful for recognizing, and communicating about, the species that live in your favorite body of water. This book enables naturalists, sport fishers, freshwater ecologists, and biomonitoring workers to identify larvae for most species of these insects occurring in and around the southeastern US. Keys for several genera are good for all of eastern North America, and several keys are the first available for their taxonomic group. Previously unpublished stage associations are reflected in the keys, and geographic and habitat distributions are discussed.


I haven't had a chance to read the book yet, but given the previous work of these authors, I'm sure they've put together a good resource for any technically inclined fly anglers fishing that part of the country. Species-specific ID information is especially hard to come by, and this seems like a valuable addition to our very limited resources.

Link: What I wish I knew about fly fishing when I started

By Troutnut on February 13th, 2017, 9:53 am
I was contacted recently by a site called Epic Wilderness with a simple but interesting question for an article they're putting together: What are the 3 most important things you wish you knew when you started fly fishing? I skipped some of the fundamentals I wish I'd known, and instead I gave some tips related to how my scientific research on salmonid feeding behavior has improved my understanding of fly fishing.

You can read my responses and those of 45 other fly fishing writers, fly shop owners/guides, and others were compiled into the Epic Wilderness Fly Fishing Tips Expert Roundup. The site did a nice job putting them together.

I'm curious to see how the other members of the Troutnut forum would have answered that question. What would be the top three things you wish you had learned earlier?

Trump is attacking trout streams on multiple fronts

By Troutnut on January 24th, 2017, 1:33 pm
I would love nothing more than to be able to keep this website apolitical and stick to fishing.

Unfortunately, a sizable minority of our population voted for Donald Trump, and now those of us who care about the environment are in for the fight of our lives. All of us with a platform to reach the public now have an obligation to call attention to what he's doing and why it's wrong.

The Pebble Mine

One key battle concerns the proposed Pebble Mine in Bristol Bay, Alaska. If built, it would be the world's largest open-pit gold and copper mine. I do not categorically oppose all mining, because we need materials to build things, and there are many places to extract minerals without major long-term risks to the environment. However, the Pebble Mine might be in the single worst location on the entire planet for this type of mine. Even the late Republican Senator Ted Stevens, an ardent supporter of resource development if ever there was one, called Pebble, "the wrong mine in the wrong place."

As an ore mine that would use chemical leaching processes to extract minerals, the Pebble Mine would store a massive reservoir of toxic chemicals behind the world's largest earthen tailings dam in a very seismically active area. Worse yet, it straddles the headwaters of two of the major river systems (the Kvichak and Nushagak) feeding into Bristol Bay. Bristol Bay supports the largest sockeye salmon fishery in the world and an estimated $1.5 billion in annual economic activity. Of all salmon species, sockeye are especially susceptible to a major spill because so much of their reproduction depends on lakes rather than small tributaries, meaning a spill in any tributary that flows into the lake could be devastating. Leaks from the mine into the Kvichak system would flow into Lake Iliamna, the largest lake in Alaska and a major sockeye producer.

For more details on the Pebble Mine, see the efforts to stop it by Trout Unlimited, the Natural Resources Defense Council. It's also opposed by the locals, the Bristol Bay Native Corporation. Conservationists were hopeful that this long battle had been won when the Anglo American and Rio Tinto mining companies walked away from the project.

Just about the only ones who want this mine built are Northern Dynasty Minerals, the Canadian mining company that owns the mineral rights, and now Donald Trump. The CEO of Northern Dynasty said today that the Trump administration has a desire to permit the mine and they're looking for a new partner to develop it. In short, Trump is trying to fast-track a project that would endanger a priceless treasure of the natural world, and thousands of American jobs that depend on it, solely to create profits for a foreign corporation.

The Clean Water Rule

Trump is also targeting the Clean Water Rule, a set of EPA guidelines clarifying how existing law applies to water bodies such as small streams. You can view a series of fact sheets about the Clean Water Rule on the EPA website right now. (I've downloaded them all to mirror in case they get scrubbed from the site.) As a fish ecologist I can vouch for the rich scientific literature documenting the importance of headwater streams to the water quality and productivity of downstream rivers. They need protection for that reason, but they're also treasured in their own right by small-stream anglers everywhere. This one could directly affect the streams you fish. The rule also protects wetlands critical to fish and wildlife.

Just as importantly, the rule exists to close a loophole being used by developers in response to the Clean Water Act legislation. The Clean Water Act prohibited dumping toxic waste directly into major rivers, so polluters started dumping it into smaller water bodies that drain into those clearly protected rivers. The Clean Water Rule closes this loophole.


Small streams. I like them. Preferably without toxic waste.

The Trump administration is committed to eliminating the rule. From their new website:

For too long, we’ve been held back by burdensome regulations on our energy industry. President Trump is committed to eliminating harmful and unnecessary policies such as the Climate Action Plan and the Waters of the U.S. rule. Lifting these restrictions will greatly help American workers, increasing wages by more than $30 billion over the next 7 years.


They made that $30 billion number up -- it's one of those "alternative facts." An analysis by actual scientists and economists found that the rule has a positive economic impact. The protected waters contribute value to the tourism industry, and the act of protecting them creates jobs because companies have to spend money (and hire people) to do right by the environment. So the rule is good for everyone in the economy except the people at the very top who want to increase their profits by cutting environmental corners and paying fewer employees.

For more details, see coverage by Hatch Magazine.

More to come

I'm sure this is just the beginning. I will continue to speak out as much as I can when it's necessary, and I'm afraid it's going to be necessary a lot.

Beautiful day on the Kenai River with Corsetti's Guide Service

By Troutnut on June 28th, 2016
I mentioned in a previous post that my friend and coworker Sierra's father started a guide service on the Kenai River this summer. Lena and I were down in the area in late June and took them up on an offer to go out fishing.

Following a winter of heavy snowpack and a recent spell of hot weather, the middle Kenai River was about three feet higher than normal, well up into the streambank trees.



Fishing from the bank was out of the question anywhere along the river, as all the gravel bars were inundated, but it was very comfortable fishing from Perry's new power drift boat using a mix of spin and fly gear.





Despite the really high water and starting--at our request--later in the day than would have been ideal for the fishing, everybody still caught trout.









Even if we hadn't caught fish, the scenery and company alone would have made for a great day on the water.



Thanks for a great trip, Perry and Sierra!
