Personnel from Arkansas Game and Fish Commission,
Norfork Federal Trout Hatchery, and members of the Beaver
Tailwater Advisory Group and Arkansas Chapter of Trout Unlimited met to help mark 5,000 stocked brown trout in Beaver
tailwater Tuesday, February 6th.
Norfork hatchery provided the hundreds of six to eight inch
Plymouth Rock brown trout. The winter stocking of brown trout is called for under the new Beaver trout management plan every other year.
However, last fall during an annual AGFC Beaver
tailwater electro-sampling, a number of wild trout showed up in the samples. The wild fish, about 40 or so in number, were from two back to back year classes of browns and rainbows.
To evaluate the strength of the wild brown trout year classes and to distinguish them from the stocked fish, all of the newly introduced browns this week had their adipose fins clipped. The adipose fin is a small fin behind the large dorsal fin.
Jeff Williams, AGFC trout management biologist, was on-site for the fin clipping and said these fins can eventually can grow back. But he said, “Browns with a clipped fin are usually easy to recognize, and any new growth on the fin will show up with a line break. Wild fish will not show that line.”
Anglers should be encouraged seeing some natural reproduction in the
tailwater. River raised trout, regardless of their strain, have the conditioning which make for excellent sport fish.



Those that helped with the fin clipping project got to see browns up close and personal. After being anesthetized, each fish was lifted out of a bucket and the adipose fin removed with a snip from a pair of scissors. They were then placed in a pipe slough where running water sent them sliding down into the
tailwater. Most recovered quickly from the procedure and by the time we were finished with the last of the trout, most had moved off out of sight of our fin clipping station.
