It's my pleasure to share these slides put together by Boyd Wright, summarizing sampling conducted by Boyd and his crew last week in Herman Gulch.
You'll recall we stocked young-of-year (YOY) and age-1 Greenbacks into Herman Gulch from 2016-2019, and have since been monitoring annually to keep tabs on those fish as they grow, and look for evidence of reproduction / recruitment. We might have expected reproduction by the earliest-stocked fish in 2020 but more likely 2021, but found no evidence of it in either of those years. We weren't overly concerned however, as YOY just a few months old are small enough to pretty easily go undetected until caught as larger fish in subsequent years.
To cut to the big news, Boyd & his crew found both YOY and age-1 greenbacks this year, indicating successful reproduction both this year and last, plus overwinter survival of last year's fish (at least one of them anyway) to age-1. Congratulations to everyone involved, in the field and at the hatcheries, on this fantastic accomplishment!
Lots of other good info in the well-annotated slides, so I encourage you to take a look.
