  1. Cease or prohibit all types of fishing in a marine protected area

    A site comparison study in 2001–2003 of a reef archipelago in the Atlantic Ocean, Brazil (Garla et al. 2006) found that young Caribbean reef sharks Carcharhinus perezi were more abundant inside a marine protected area where fishing had been prohibited for over 12 years, compared to an adjacent fished area. Average catches of sharks were higher inside the unfished area than the fished (unfished: 0.16 sharks/h, fished: 0.03 sharks/h). Sharks caught in both areas were almost all smaller immature individuals (71–170 cm). Fernando de Noronha Archipelago (26 km2) is 345 km off the northeastern coast of Brazil and has a marine protected area, no fishing since 1988, around the coastline of its main island out to 50 m water depth. The rest of the area allows fishing and boat traffic. Monthly from March 2001 to February 2003, fishing for sharks was done at 148 randomly selected sites around the archipelago, inside (79) and in the fished area outside (69) the protected area. At each site two baited, single-hook handlines were deployed simultaneously from a small boat. Catch per unit effort of sharks was calculated from the time the first hook was deployed to the time the last hook was removed. Number, length, and sex of captured sharks (143) were recorded.
