Greenback Aficionados, 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. Enjoy! Harry Harry Crockett Native Aquatic Species Coordinator Use the link below to download the presentation slides in PDF format.
