Comparison of Growth, Survival, and Body Composition of Muskellunge and Tiger Muskellunge Fed Four Commercial Diets

Abstract
Feed is one of the largest annual costs in fish production. Various commercial feeds are used for muskellunge (Esox masquinongy) and tiger muskellunge (E. masquinongy × E. lucius), but no data are available that compare growth and survival of these two fishes on these diets. Growth and survival were evaluated over 8 weeks for both muskellunge (initial mean total length, 172 mm) and tiger muskellunge (187 mm) fed four commercially available feeds: Biodiet Grower, Biodry 1000, Abernathy S8-2 (84), and W-16. Across all diets, tiger muskellunge grew more than 1.5 times as fast as muskellunge. Both muskellunge and tiger muskellunge grew faster on three diets developed for coldwater species (Biodiet, Biodry, and Abernathy), than on the one developed for coolwater species (W-16). Muskellunge also grew faster when fed Biodiet or Biodry than when fed Abernathy. Differences in growth may be related to dietary protein levels. Body composition was affected by diet; percent fat was highest for both species fe...
