It has also been observed that juveniles maintained at a mean temperature of 24.3 ☌ channel a high proportion of ingested energy to biomass production, suggesting that this is the optimum temperature for the growth of O. It has been shown that high ingestion rate and efficient use of fatty acids (as well as other nutrient categories) occur at lower temperatures, beyond the automatous effect that temperature has on enzyme kinetics. maya, probably due to several factors acting simultaneously: (1) a reduction of basal metabolism and consequent reduction in overall activity and (2) a reduction of digestion rates and a better assimilation of nutrients, including fatty acids, from food ( Noyola et al., 2013a,b). Temperatures around 24 ☌ favour growth and the energetic balance of O. Conch shells are offered as refuges for the octopuses. Prefattening 7.5 m 2 tanks designed to maintain Octopus maya juveniles during the first 60 culture days. gigas) fishery is practically depleted along the mainland coast, although commercial fishing continues on Chinchorro Bank.įigure 1.18. Spiny lobster fishery subsists with some oscillations ( Briónes and Lozano 1994), but conch ( S. An ongoing shift from fishing to guiding tourists to reefs coincides with harvesting smaller fishes of a wide array of species to fill the demand of local restaurants. Nowadays, most commercial fin-fisheries have suffered a reduction in mean fish size and catches. The expansion of the resort area of Cancún has opened this territory to the pressures of modern development. The Caribbean coast of Mexico was formerly an isolated and completely undeveloped area, with the exception of Cozumel and the Mujeres islands. guttatus), conch ( Strombus gigas), and of several species of groupers and snappers. But is mostly directed to high quality species like spiny lobster ( Panulirus argus and P. In the Caribbean reefs, the fishing effort has been intensive over the last twenty years.
