Resumo(s)
Recreational fishing at Parque Natural do Sudoeste Alentejano e Costa Vicentina
(PNSACV) was limited by legal restrictions, including fishing ban in Ilha do Pessegueiro
and continental adjacent area. All the area was later classified as protected. The aim of
this study was to evaluate the ecological effects of a 2 year period (2009-2011) of
marine protection, to propose monitoring methodologies and suggest management
improvements for recreational and commercial fishing. Ecological effects of the stated
protection were studied on intertidal organisms (limpets and sea snails) that use to be
explored by recreational fishers on the rocky shores of the cited area, and on the
community of macro-epibenthic organisms. The protected area was compared with non
protected control areas. Variance analysis didn’t show effects of protection at both area
and local levels in the abundance and size of limpets and sea snails. Variability at local
scale was detected. Compared with previous data the abundance and size of limpets
decreased but the abundance of large limpets maintained. Insufficient recovery time,
predation by other mollusk consumers and deficient regulatory enforcement are
possible causes for the obtained results. Social conflict resolution is essential.
Collaborative governance is suggested as a management strategy for the marine
protected area in PNSACV.
