“…Por fim, como informação adicional, obtida por mera observação do processo, notou-se na experiência obtida na Reserva Extrativista do Mandira, que a experimentação de direções de manejo levou ao aprendizado coletivo e à construção de instituições locais -regras de manejo de limitação de usuários, parada do Mendonça & Machado (2010), recomendaram medidas de ordenamento do extrativismo da ostra em Cananéia focadas nas práticas extrativistas e no controle do número de usuários, reafirmando que a co-gestão participativa é fundamental para aumentar a eficiência das ações. Estas medidas poderão, de acordo com os autores, reduzir conflitos e dar legitimidade ao processo, promovendo a gestão por um caminho sustentável.…”
