Abstract
Red octopus (Octopus maya) is an important fishery resource in Mexico, due to its high commercial value and domestic and foreign demand. An alternative to fishing is the mariculture. Cephalopods digestion is a two-part process: extracellular and intracellular. This paper describes the progress made in Octopus maya digestive physiology study, particularly, in the digestion temporality, absorption and assimilation of crab in an attempt to assess the nutrients dynamic and usage along the digestive tract and, how these are transported, stored and used as an energy source for growth.
