Carnivorous trout grow slowly on fishmeal-free diets due to low feed intake

A recent study from the University of California Santa Cruz tracked outcomes of trout fed 100% fishmeal-free diets consisting of three different kinds of algae. Although two of the three algae species tested performed considerably better, and even produced harvested fish with higher levels of omega-3, the fish experienced slower growth than trout fed standard diets.
