Feeding transition of cultured largemouth bass (Micropterus salmoides, Lacépede, 1802) from an artificial pelleted feed to live prey

Original language description

Previous field studies indicated that hatchery pellet-reared largemouth bass Micropterus salmoides failed to adapt to feeding on live prey after being stocked into lakes. We designed a series of 48-h laboratory experiments to compare the feeding successand behavior of pellet-reared and wild largemouth bass. Prey used during these experiments were bluegill Lepomis macrochirus and Seminole killifish Fundulus seminolus. As solitary predators, pellet-reared largemouth bass did not eat any live prey, but expended a considerable amount of energy swimming around the tank. This type of behavior would contribute to poorer survival in the wild. In contrast, wild bass ate an average 6.0 +- 1.3 bluegill and 2.4 +- 1.5 Seminole killifish during the experiments andspent less time swimming than pellet-reared largemouth bass. Pellet-reared largemouth bass exhibited a group feeding mentality. When placed in a tank alone with live prey, none of the pellet-reared bass fed; however, when in a group of n
