Evaluation of Commercial Feeds for Rearing Advanced Fingerling Walleye
An experiment was conducted to evaluate the suitability of 5 commercial feeds3 for rearing juvenile walleye (Stizostedion vitreum). Two open-formula feeds (the coolwater W-16 formulation and the Abernathy salmon formula) and 3 closedformula trout and salmon feeds (Glenco Mills trout feed, BioMoist, and BioDry) were evaluated. In the first phase, walleyes (age —166 days posthatch, 161 ± 13.2 mm total length (TL), and 39.2 ± 10.4 g) were stocked at 4 densities from 6.7 to 14.6 g/liter (20 to 50 fish per tank) and reared separately on W-16 and the Glenco Mills trout feed for 70 days (from 166...
