Brook Trout genome project

Updated: Sep 2, 2019

Elucidating the evolutionary architecture of one of North America's most iconic sport fish.

Background The Brook Trout (Salvelinus fontinalis) is a cold-water fish species native to Eastern North America and is one of the most iconic and economically important fish in the region.

The Brook Trout is the state fish of nine U.S. states and the Provincial Fish of Nova Scotia in Canada. Brook Trout are commonly found in large and small lakes, rivers, streams, creeks, and springs throughout the region. They prefer clean, clear, cold oxygenated water and can only tolerate a narrow pH range, making them acutely sensitive to poor oxygenation, habitat degradation, warming waters, and changes in pH caused by environmental factors such as acid rain. Comparative studies that utilize genomic resources across populations and species often rely on a reference genome for mapping variation at the individual level, allowing for detailed information about genetic diversity, functional differences and adaptive potential. By sequencing and making available the first whole genome for this species, we have the opportunity to facilitate a wide range of future studies examining the the evolutionary history of this iconic fish. Not only will genomic resources make evolutionary and functional studies of this historically important fish species possible, but it will also provide additional genetic resources to wild fisheries managers ultimately benefiting the conservation and management of this important local resource.

Funding & Acknowledgments This genome sequencing project is funded by Trout Power Inc. and would not be possible without the help and support of Jordan Ross, John Montefusco, Mark Usyk, Keith Tidball, Paul Miller and Bob Fitak.
