Ostreiculture in the extreme northern islands of paraná coast

The extreme northern islands of Paraná Coast are populated by impoverished communities that see in the ostreiculture as the main alternative for income generation, but little is known about the conditions of cultivation and commercialization practiced by these families. In this context, in order to know the factors that interfere in the development of this activity, a descriptive exploratory research was conducted between July 2017 and January 2018, with interviews by accessibility and receptivity with 30 oyster producers. The study revealed that oyster farmers are an average 35 years old and they were characterized by low use of production technology, with the removal of the seeds for cultivation in an extractive way and the cultivations were performed only with the family work force. The difficulty of developing activities in a collectively way, and the low demand for oyster in the winter season are the main limiters in the development of the activity. It seems that the limiting factors could be softened as the communities strengthened their social force, especially the capacity of collective organization, which could result in a greater bargaining power with other social factors involved in the oyster production chain in the extreme northern of Paraná Coast.
