WebWe used three assessment approaches based on 12 microsatellite loci to examine the extent of hatchery introgression in 406 wild brook trout populations in North Carolina. We found high levels of differentiation among most collections (mean F′ST = 0.718), and among most wild collections and hatchery strains (mean F′ST = 0.732). WebMay 10, 2024 · In particular, introgression between hatchery and wild individuals can cause declines in wild population fitness, resiliency, and adaptive potential, and contribute to local population extirpation. However, low survival and fitness of captive-raised individuals can minimize the long-term genetic consequences of stocking in wild populations, and ...
Endemic Sicilian Brown Trout Endangered by Hatchery Introgression …
WebJan 25, 2024 · This data set includes information on 406 wild brook trout populations from across the State of North Carolina. Key genetics metrics on diversity and the extent of hatchery introgression are presented. These data accompany the following article: Kazyak, D.C., Rash, Jacob, Lubinski, B.A., and King, T.L., 2024, Assessing the impact of … WebJun 5, 2024 · Our results suggest that introgression of hatchery‐derived genotypes can occur at low rates, even in actively stocked ecosystems and across a range of habitats. … penyebab blue screen
Limited hatchery introgression into wild brook trout …
Webhatchery influence and overall genetic structure of Red-band Trout in this basin segment are unknown, and this lack of knowledge hinders informed conservation and management. In this case study, we examined hatchery introgression and the genetic structure of Redband Trout from this sec-tion of the Deschutes River basin, which includes four WebOct 13, 2024 · In fisheries management, understanding anthropogenic impacts on fish population genetic structure is essential because genetic diversity is a fundamental attribute contributing to a species’ evolutionary capacity. An extended history of supplemental stocking has led to the introgression of genes from non-local, hatchery-reared brook … Webheavily stocked with hatchery raised Brook Trout, the degree to which introgression of hatchery genetics into wild populations occurs is also being examined. Results suggest significant introgression has occurred throughout the study area. penyebab blue screen memory management
