25.5 Conclusions
Future tendencies are determined by the market but the results of controlled
cultivation indicate that juvenile production is possible, and at 12 °C, it takes 70
days of egg incubation, 70 days of paralarval cultivation and a further 90 days to
obtain juveniles of approximately 2 g, starting from eggs collected from the subtidal
zone. However, there are no studies reporting growth rate of juveniles in grow-out
until the harvest size of the octopus. Based on the specific growth rate of early
juveniles documented by Uriarte et al. (2010), the specimens could reach a weight
of 50 g in 260 days. Therefore, the period of total production could reach up to 14
months considering the collection of eggs from the wild as the beginning of the
productive cycle.
