“…In addition, embryos incubated at 22 and 26°C had higher hatch rates and survival after 10 d of fasting, indicating that the optimum temperature range for incubation of embryos of O. maya is between 22 and 26°C. While the recommended temperature for cultivation of embryos of O. maya is 24°C (Rosas et al, 2014a;Vidal et al, 2014), this is the first detailed study on the effects of temperature in O. maya embryo development. The optimum incubation temperatures of O. maya embryos originate in the reproductive biology of Fig.…”

“…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). However, there is insufficient information to know whether higher temperatures might reduce incubation time (50 d), or whether there are temperature limits for embryonic development.…”

“…Octopus maya is relatively easy to cultivate because its holobenthic development means that juveniles resemble adults a few days after hatching (Rosas et al, 2014a). 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 adults, this process takes around 480 min to be completed, indicating that this type of animal should be fed at least every 8 h to maintain its health in captivity (Linares et al, 2015). At a semi-pilot scale, this feed protocol has been followed for more than 5 years (Rosas et al, 2014); adults of O. maya were fed every 8 h using fresh scraps of marine fish or fresh crab (Caamal-Monsreal et al, 2015) or a diet formulated to stimulate spawning in laboratory conditions (Tercero-Iglesias et al, 2015). Under these conditions the number of eggs spawned was quite similar to those observed in wild spawns (Vidal et al, 2014), indicating that laboratory animals fed every 8 h reach a similar healthy condition to those on the continental shelf of the Yucatán Peninsula, where this species lives (Avila-Poveda et al, 2016; Angeles-Gonzalez et al, 2017).…”

Digestive Physiology of Octopus maya and O. mimus: Temporality of Digestion and Assimilation Processes

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.

“…Constant aeration is essential to keep oxygen levels above 5 mg L −1 (Rosas et al . ). Nevertheless, care should be taken with air bubbles (especially extra‐fine bubbles), as cephalopods are susceptible to air entrapment, especially in the mantle cavity.…”

Aquaculture is among the fastest growing industries in the world and the fastest in the food production sector. However, not all aquaculture organisms are produced for human consumption. Indeed, an important fraction of aquaculture products target a wide variety of applications, from pharmaceutical, cosmeceutical, ornamental and nutraceutical applications, as well as biofuel production, conservation efforts and academic purposes, among others. Despite the increasing importance of aquaculture for non‐food purposes, a comprehensive review covering the state of the art of this topic, its latest developments and future trends is missing. Here, we review what marine organisms are produced for non‐food purposes, as well as why and how they are produced. Instead of providing a thorough methodological review, production protocols are briefly summarized and an updated guide to the most relevant literature is provided. We overview current developments driving the aquaculture of non‐food organisms, underpin their most significant applications and highlight future prospects for non‐food aquaculture.
