Diets affect abalone meat quality, shell color

A preliminary study investigated the effects of diet on the meat quality and shell color of Pacific abalone. A test diet and a commercial abalone feed resulted in lower meat protein content compared to that achieved with a diet of Pacific dulse seaweed. The artificial diets also caused the abalone to have yellow or orange shells. The seaweed diet alone resulted in abalone with dark-brown shells. However, a combination of seaweed and either artificial diet improved abalone growth, meat quality and shell color.
