Title:

Migrations of searun Arctic char in a changing Arctic: Integrating acoustic telemetry, physiology, and genomics

Agreement Number:

PKC-NST-1718-0036

Agreement Value:

$423,270.00

Agreement Date:

Jul 28, 2017 - Mar 31, 2020

Description:

Study the migratory ecology of the searun (anadromous) Arctic char of the Cambridge Bay region. The study will address key challenges in the management of and important fishery, provide information on critical freshwater and marine habitats, and establish a basis for understanding the physiological constraints that will be most important in predicting the response of the species to a changing Arctic.

Organization:

Polar Knowledge Canada

Expected Results:

Objective 1: Long term monitoring using acoustic telemetry will directly link inter-annual differences in individual migratory behaviour to environmental and meteorological variables (e.g., onset of sea ice melt). Objective 2: Identification of critical spawning habitats will provide spatial data on sites of importance and will characterize the type of substrate, temperatures, dissolved oxygen levels, and depths that are critical for successful Arctic char reproduction. Objective 3: Genomic data will confirm whether different spawning aggregations are genetically differentiated at neutral markers, indicating reproductive isolation, and will permit the assessment of whether these stocks are locally adapted. Objective 4: The physiological assays will allow the determination of optimal, sub- optimal and critical temperatures for cardiac performance and aerobic capacity in migrating Arctic char, thus characterizing the susceptibility of specific populations to changing river conditions. Linking the physiology and genomics data will also allow the determination of the genetic basis of physiological performance.
