This research analyzes the producing cost of oysters grown during the summer and winter, to find out whether the mortality of oysters associated with the high temperatures of seawater in the summer is an important factor for cultivation in this season. The results showed that, on the monitored farm, production costs were quite similar between the two seasons. The main differentials found in the analysis were the higher incidence of predators in the summer and the higher costs of pro-labore in the winter, due to the need for a longer growing period when the cycle starts in the fall. A change in farm management has been recommended to avoid predation, and to allow the producer to take advantage of the shorter growing season observed in the summer.
