Utah Chapter AFS Annual Meeting 2014

Standard

UTAFSThis year the annual meeting for the Utah Chapter American Fisheries Society will be held in Price Utah at USU Eastern. You can learn more about this meeting by clicking on this link  http://utahafs.org/annual-meeting-2014-2.  These meetings are a great opportunity to network with professionals from many state and federal agencies. Early registration ends on February 10th, so get on it now. Our subunit can cover some of the cost of attending this meeting, so let me know if you are going to the meeting and when you register and we can reimburse some of the cost. It will be a worth while meeting to attend!

Steelhead Trip

Standard

For those of us who were able to go, the USU AFS steelhead trip was certainly an experience to remember.  We had the opportunity to tour a state of the art fish hatchery located on the East fork of the Salmon River near the foothills of the beautiful Sawtooth Mountains.  Although the hatchery was not working with steelhead during our visit, we were still able to witness the methods which are used to sustain a healthy chinook population in Idaho’s watersheds.  In addition to touring and networking with the sawtooth hatchery personnel, we also had time to fish for steelhead to help us better understand their behavior and life histories.  With lots of hard work and patience, several members of the group were lucky enough to hook into a determined steelhead as they proceeded upstream on their 700 mile journey.

Biologist Phil Kuntz with the Idaho Department of Fish and Game explains the process of imprinting in the chinook that they raise in in their facility. Imprinting is a biological process where some fishes are able to remember the exact tributary where they were hatched.  As these fishes smolt and move downstream toward the Pacific Ocean, the chemical signature of the water is imprinted in their memory.

Members of the USU AFS Subunit learn the complexities and obstacles that come with raising fishes from egg to fingerling.  The Sawtooth Hatchery maintains chinook salmon for 18 months before releasing them into the river where they smolt.  Smolting is the process where salmonids undergo physical changes in preparation for their migration to the Pacific Ocean.

Chinook sac fry remain in the incubator until they are capable of eating and swimming on their own.  This hatchery environment ensures an increased chinook survival rate by maintaining optimum water temperatures and flows, while also eliminating predation factors.

Once the chinook fry consume their entire yolk sac, they are moved to the indoor raceways where hatchery personnel become responsible for supplying them with proper nutrients.

Before the chinook are released into the river, they are brought to the outdoor raceways.  This is an important step in raising these fish because they rely heavily on the timing of the Sun to trigger their natural smolting and imprinting processes.

Sawtooth hatchery personnel throw food into a raceway which is quickly followed by an explosive feeding frenzy.  Chinook are thought to be the most prized of the Pacific salmon as they can grow to be 5 feet long and well over 100 pounds.  Most of these Chinook will find their way to the Gulf of Alaska where they will spend 2-3 years before returning to spawn and die.

Phil gives us an up-close look at the Sawtooth Hatchery trapping station.  Returning fishes navigate their way through this station where biologists sort, spawn, and inspect them for pathogens.  This station is also capable of automatically logging pit tags as the fishes move up.  The collected data is then instantly sent to their headquarters in Boise, ID.

remove the steelheads otoliths.  We were able to collect otoliths from 5 different steelhead and plan to examine them in further detail to help us better understand their life histories.

I was in disbelief when I landed my first steelhead.  This fish was not processed as he had an unclipped adipose fin which indicated he was a native fish.  I was happy to quickly release him and watch him continue on his journey upstream.

All in all, this trip turned out to be a great learning experience as well as a great time fishing of course.  A special thanks to all of those who made this unforgettable trip possible for us:  Officers of the USU AFS Subunit, Dr. Pheadra Budy,  Gary, the Idaho Department of Fish and Game, Jan’s Mountain Outfitter, and the USU ORP.  Thank you!

Native Bonneville cutthroat trout in Right Hand Fork

Standard

On Wednesday October 16th Right Hand Fork, a tributary to the Logan River, became home to 458 juvenile Bonneville cutthroat trout. This was a very exciting event for many people.

Right Hand Fork once was dominated by brown trout which made it impossible for the native cutthroat populations to exist in this tributary. Over the last several years brown trout have been removed by mechanical means then ultimately the stream was chemically treated to completely remove the population of exotic brown trout.

As of today Right Hand Fork has only native Bonneville cutthroat trout in its waters. Now these fish can thrive without competition with brown trout. It will also soon serve as a source of native fish to the main stem Logan River.

ImageImageImageImageImageImageWe are fortunate as a student AFS group to have been involved with the Right Hand Fork project, it was a fun day to be out and see these little fish get sent into RHF. Thanks to many different groups and agencies, Utah DWR, US Forest Service, Trout Unlimited, and Utah State University for providing opportunities such as this one for our USU AFS Unit.

Fall ’13 Opening Social

Standard

The opening social at 2nd dam was a success.  Thanks to all of those who participated, and a special thanks to Bryce, our grill master.  We had a great time mingling, fishing, and eating tasty food.  It was a pleasure to meet the new members of the USU AFS subunit, as well as their families and friends.  Stay posted on upcoming events and don’t miss out!
