Winter flounder Pleuronectes americanus is being developed for aquaculture in Atlantic Canada. Weaning, the switch from a live diet to formulated feed, is a critical stage in the culture of any fish species. In this study, we used wild young‐of‐the‐year stock to determine whether juvenile winter flounder can be weaned from live, cultured Artemia onto dry feed. The dry feed used was originally formulated for turbot Scophthalmus maximus and cod Gadus morhua by BP Nutrition, Stavanger, Norway. The performance of live feed and dry pellets was compared in terms of survival, growth and feed efficiency over three months. We were able to wean wild juvenile winter flounder onto dry feed after one week. Increased specific growth rates and feed efficiency ratios in weaned juveniles indicated that prepared diet was a better food source than Anemia . Survival was not influenced by food type.
