This project is a collaboration with the US Fish and Wildlife Service and involves conducting an assessment of the landlocked Atlantic salmon restoration efforts in Lake Champlain. This will be done in part via the use of microsatellite DNA markers that will be used to identify returning spawners by assigning them back to their parents and thereby allowing us to compare yields from various stocking strategies. In addition to this, a more detailed look at the surviving individuals’ genetic makeup will be constructed through the use of a large number of single nucleotide polymorphisms (SNPs). By examining a broader range of genetic markers for individuals that have survived to maturity, I hope to determine whether certain genotypes are attributing to their success and which may not be imposing a survival advantage. I will also be using creel surveys, analyses of spawning habitat and spawning returns as well as egg survival experiments in order to determine what other factors (dietary, biotic, abiotic or anthropogenic) may be hindering, or helping the return of this culturally and economically important species to Lake Champlain and it’s tributaries.
