“…Previous experiments performed with O. maya confirmed that animals fed with crab used ingested protein as a source of energy via the gluconeogenic pathway, which facilitated the accumulation of glycogen and its posterior release as glucose , Martínez et al 2012, Baeza-Rojano et al 2013. In the present study, DG protein and glycogen levels in O. maya and O. mimus followed an inverse relationship throughout the digestive process, confirming the role of protein as a source of energy.…”

“…That study demonstrated that animal diets made with fish meal and fish hydrolysed protein have low growth rates and lower DG energy content than octopuses fed crab, suggesting that the type of food determines not only the amount of energy directed to growth, but also the energy stored in the DG that will be used to process the next meal. Those results and others obtained from experiments performed with O. maya indicate that the type and level of protein are the principal source of metabolic energy in the muscle, while lipids are the principal source of energy for DG intracellular metabolism (Martínez et al, 2011; Rosas et al, 2011; Baeza-Rojano et al, 2013). Similar results were observed in O. mimus , indicating that the biochemical pathways observed in O. maya could be generalized to other octopus species (Linares et al, 2015).…”

“…Previous experiments with O. maya confirmed that glucose, synthesized via the gluconeogenic pathway, is the final energetic product of protein catabolism (Martínez et al, 2011; Rosas et al, 2011; Baeza-Rojano et al, 2013). Linares et al (2015) showed that protein catabolism and glycogen synthesis in O. maya and O. mimus followed an inverse relationship throughout the digestive process.…”

Digestive physiology is one of the bottlenecks of octopus aquaculture. Although, there are successful experimentally formulated feeds, knowledge of the digestive physiology of cephalopods is fragmented, and focused mainly on Octopus vulgaris. Considering that the digestive physiology could vary in tropical and sub-tropical species through temperature modulations of the digestive dynamics and nutritional requirements of different organisms, the present review was focused on the digestive physiology timing of Octopus maya and Octopus mimus, two promising aquaculture species living in tropical (22–30°C) and sub-tropical (15–24°C) ecosystems, respectively. We provide a detailed description of how soluble and complex nutrients are digested, absorbed, and assimilated in these species, describing the digestive process and providing insight into how the environment can modulate the digestion and final use of nutrients for these and presumably other octopus species. To date, research on these octopus species has demonstrated that soluble protein and other nutrients flow through the digestive tract to the digestive gland in a similar manner in both species. However, differences in the use of nutrients were noted: in O. mimus, lipids were mobilized faster than protein, while in O. maya, the inverse process was observed, suggesting that lipid mobilization in species that live in relatively colder environments occurs differently to those in tropical ecosystems. Those differences are related to the particular adaptations of animals to their habitat, and indicate that this knowledge is important when formulating feed for octopus species.

“…In culture conditions and after hatching, juveniles of O. maya are routinely fed with amphipods together with a formulated diet that covers nutritional requirements until octopuses reach 250 g when they are harvested (Baesa-Rojano et al, 2012;Martinez et al, 2014). In the semi-pilot-scale area for hatchling production of O. maya at the National Autonomous University of Mexico, embryos are maintained at 24°C, the temperature recommended for cultivation of embryos of this species (Rosas et al, 2014a;Vidal et al, 2014).…”
