Establish community-based fisheries management
A replicated, site comparison study in 2013 of 20 sites in the Paterson Inlet, Foveaux Straight, New Zealand (Twist et al. 2016) found that sites within a customary fisheries area where management was community-based had more New Zealand scallops Pecten novaezealandiae, but they tended to be smaller, compared to adjacent sites in a marine protected area prohibiting all fishing (no-take reserve) and a recreational harvest-only area. Scallop abundance was higher inside the customary fisheries area (3.62 scallops/m2) compared to the other sites (no-take: 0.63 scallops/m2; recreational: 0.56 scallops/m2). Scallops tended to be smaller in the customary fisheries area (104 mm), compared to the no-take reserve (110 mm), and the recreational area (132 mm; size data were not statistically tested). In June 2013, divers counted and measured scallops in three to nine transects (100 m2) at each of 20 sites: six in the customary fisheries area (community-based management, see paper for details), three in the no-take reserve (designated in 2004), and three in the recreational harvest-only area.

Designate a Marine Protected Area and prohibit all types of fishing
A replicated, site comparison study in 2013 of twenty sites in the Paterson Inlet, Foveaux Straight, New Zealand (Twist et al. 2016) found that sites within a marine protected area prohibiting all fishing (no-take reserve) had more New Zealand scallops Pecten novaezealandiae after nine years compared to adjacent sites in a recreational harvest-only area, but fewer than at sites in a customary fisheries area. Scallop abundance was higher inside the no-take reserve (0.63 scallops/m2) compared to the recreational area (0.56 scallops/m2), but not compare to the customary area (3.62 scallops/m2). Scallop measured on average 110 mm inside the no-take reserve, 132 mm in the recreational area, and 104 in the customary fisheries area (differences not statistically tested). In June 2013, divers counted and measured scallops in three to nine transects (100 m2) at each of 20 sites: three in the no-take reserve (designated in 2004), three in the recreational harvest-only area, and six in the customary fisheries area (community-based management, see paper for details).
