Based on literature and original experimental (aquarium) and natural (the Mediterranean Sea) data, the author’s point of view on the nature of the specific dynamic food effect (SDA) in fishes is substantiated. It is concluded that, in fishes the SDA exists constantly because this effect is supported by continuously proceeding digestion of food. The intensity and duration of the SDA as an energy metabolic process depend on the ratios of chemical components in food.
