The Calibration of Bioenergetic Models for Juvenile Acipenser brevirostrum to Natural Feeding Conditions
Two experiments were run to determine the effects of food type, food regime, and water temperature on the consumption and growth rates of young of the year Acipenser brevirostrum (shortnose sturgeon). Food regime and water temperature alone did not have significant effects on growth or consumption rates. Food type was highly significant for growth rates. Sturgeon fed bloodworms grew significantly less than those fed protein pellets. Water temperature and food type combined had a significant effect on food type. As temperature increased, sturgeon consuming bloodworms grew less and those consuming pellets grew more.
