DEC Collect Salmon Samples to Study Effects of Vitamin B
NYS_DEC and SUNY Brockport researchers collected steelhead and Chinook
salmon from two small back channels near the Meadow Run area of the DSR
this October. The purpose of the collection is to continue studies on
Vitamin B (thiamine) deficiency in Lake Ontario trout and salmon. The
current study, measures thiamine levels in adult salmon and their eggs
to determine effects on egg and fry survival.
an essential nutrient for reproduction of salmon and trout. Alewife, the
main prey fish in Lake Ontario, contain a naturally occurring enzyme
called thiaminase which destroys thiamine. Salmon and trout which eat
alewife can become thiamine deficient, reducing the survival of their
eggs and newly hatched fry.
ln severe cases, as was observed in steelhead during fall 2014, low thiamine levels can kill adult fish.

appreciation for a high level of cooperation from anglers at the DSR.
Every year in late summer, when leaves start to turn, and temperatures begin to drop in upstate New York, a growing number of anglers eagerly anticipate the fall salmon run. If you are one of them, you know what we mean.
Each year the magic of the fall salmon run happens over a few short weeks. Mother Nature has the upper hand when it comes to the exact timing of each year’s run and how many fish actually show up. But, that’s part of the excitement - and frustration - in waiting for that one special day when hundreds and thousands of Cohoes and Kings migrate to their spawning grounds.
When that one special day happens, the sheer number of these magnificent fish can literally crowd out the anglers themselves. For those who have not yet experienced “The Run”, It's difficult to explain the feeling one gets when such large quantity of big fish are unusually close fighting each other to get upstream. So when it happens, if it happens, there is an adrenaline rush in the challenge, the thrill, and sometimes even the exhaustion, of it all.
On that special day, there also comes a time when anglers simply pause in recognition, marveling at nature and the magnitude of what is happening all around them.
At the DSR we live for that moment. Salmon season is a time of homecoming for the, when we welcome returning staff, guides, and guests and introduce new ones to our great sport. We work hard to prepare all year for the run, so it is bittersweet to see salmon season coming to a close.
Thanks to everyone who joined us on the water this salmon season. It is always rewarding to share in each fishing adventure with you. We already can’t wait for next year!
