Abstract
Juvenile lake trout (Salvelinus namaycush) in Lake Champlain are stocked at age-0 in fall as Lake Champlain (LC) strain and at age-1 in spring as Seneca Lake (SL) strain, or are naturally produced. I compared performance among these three groups based on their lipid content and used genetic analyses to identify the strain of stocked individuals. Average lipid content is highest in wild juveniles, but SL strain fish average higher lipid content than LC strain individuals. Stocking of the SL strain ended in 2021 which could lead to population declines considering SL strain fish perform better than LC strain fish.
