ABSTRACT: Rehabilitation efforts of lake trout (Salvelinus namaycush) in Lake Huron have resulted in increased recruitment and capture of young wild lake trout in annual bottom trawl surveys conducted by the U.S. Geological Survey. To better understand the spatial distribution and food habits of wild juvenile lake trout, we performed diet analyses on 311 of 343 fish captured in bottom trawls at six ports in Lake Huron during October/November 2008–2017. Lake trout ranged in size from 27 to 371 mm, representing approximately three age classes. Most of the fish (83%) were captured at 46–64 m depths at the two northernmost ports, typically below the thermocline. Mysis diluviana was the most prevalent diet item, found in 222 of 299 fish with non-empty stomachs (74%), followed by Bythotrephes longimanus (31%), and round goby (Neogobius melanostomus; 11%). Young-of-year lake trout (Mysis and Daphnia, while larger lake trout converted to mostly fish-based diets at age 2+. Compared to a previous diet analysis of young Lake Huron lake trout from 2004–2006, fish in the current study consumed more unique prey items (12 vs. 6) and fish species, although many of the lake trout in the current study were larger than those analyzed in the past (74–120 mm). While the variety of taxa consumed by young lake trout has increased since the last study period, the most commonly observed prey items after Mysis were nonnative taxa. Mysis remain an important early food for lake trout in Lake Huron.
