“…Previous studies provided evidence strongly suggesting that marine reserves enhance the abundance and size of certain fish specles (usually fishery target species) within their boundaries (Bohnsack 1982, Bell 1983, Alcala 1988, Buxton & Smale 1989, Russ & Alcala 1989, Roberts & Polunin 1991, Bohnsack et al 1992, Polunin & Roberts 1993. However, there is little information concerning movement of fishes out of reserves or other biological correlates of differences among species in the protective effect of reserves.…”

High population densities of larger fish withln reserves could result in emigrat~on of fish to surrounding non-reserve areas, producing a gradient of abundance and mean size across the reserve boundaries. The difference in fish abundance and size between reserve and non-reserve should be higher for sedentary than for mobile species and for highly catchable than for less catchable species. To test these hypotheses we estimated the abundance and size of fishes by trapping and visual census on fringlng reefs in Barbados: 5 reefs with~n the 2.2 km of the Barbados Marine Reserve (BMR) and 8 reefs in the non-reserve (NR) area within 4 km of the reserve boundaries. The abundance of large, trappable size fish of all species combined was higher in the BMR than in the NR, but abundance of small, nontrappable fish did not differ between BMR and NR. Trap catches decreased gradually with distance from the BMR center, but this gradient of abundance was less evident in visual census counts of trappable size fishes of all species combined, and not apparent in trap or visual census estimates of abundance for individual species. Mean size was larger in the BMR than in the NR for 18 out of 24 species.The relative differences in both abundance and size between BMR and NR did not differ between mobile and sedentary fish taxa. However, for sedentary taxa, the relative differences in abundance and size increased with trappability (the vulnerability to traps, which are the most common fishing method). These patterns suggest that the BMR does protect the fish community from fishing mortality and that em~gration rates are generally low. Trappability and mobility depend on complex behavioral characteristics of fishes and are potentially important for the functioning of marine reserves.

“…In general, the results show significant differences for particular species (Bell 1983, Paddack & Estes 2000, see also other references in review papers cited above), taxonomic families (e.g. Alcala 1988, Jennings et al 1996, Letourneur 1996, Wantiez et al 1997a, or other groups of species, e.g.…”

“…Paddack & Estes (2000) compared fish assemblages between sites, while accounting for substratum composition. Sometimes, an additional factor related to habitat was included in the model, such as depth (Bell 1983, García-Rubies & Zabala 1990, Kelly et al 2000, reef type (Chapman & Kramer 1999), or some other definition of habitat (McCormick & Choat 1987, Castilla & Bustamante 1989, García-Charton et al 2004.…”

We propose a statistical approach based on multivariate analysis and general linear models to test the consequences of removal of reserve status from the Abore Reef fish assemblage of the Abore Reef reserve, New Caledonia. Consequences on fish density were examined at the level of fish assemblage, accounting for habitat. Fish counts and habitat-related information were collected before and after the removal of reserve status, both inside and outside the reserve. Species groups were constructed on the basis of additional information on behavioural characteristics and taxonomy. The impact of the removal of reserve status was assessed by using 2 habitat proxies corresponding to 2 spatial scales and by considering several criteria for grouping species. Habitat appeared to be a determining factor in explaining density variations. Significant positive effects were found for several species groups such as macrocarnivores, piscivores, herbivores, Lethrinidae and Siganidae. A counterintuitive negative effect was observed for Acanthuridae. No significant differences between the area which remained closed to fishing and the area open to fishing were found for the other species groups. The approach allows for a synoptic diagnosis of the impact of changes in reserve status at the fish assemblage level. It could be used to develop and select potential indicators for monitoring such impacts on fish assemblages in coral reef ecosystems and in other contexts.

“…However, there are still certain problems, such as the illegal selling of the catches or the resistance of spear fishermen to comply with protection measures, despite spear fishing could be policed and possession of spear fishing equipment could be a controlled activity. Although spear fishing is usually carried out at low intensity along all suitable stretches of coast, (except during competition events), there is published evidence that, in the western Mediterranean, spear fishing can affect the composition of fish communities [56][57][58][59] and the structure of fish populations [60][61][62]. Conflicts between different user groups can arise because recreational fishing may take place in areas closed to commercial fishers and they may compete for the same resources.…”

a b s t r a c tA general conceptual framework for the management of marine protected areas (MPAs) was developed. The driver-pressure-state-impacts-response (DPSIR) framework was used to determine the elements affecting MPAs. The developed evaluation framework helped to select an appropriate suite of indicators to support an ecosystem approach, an assessment of the MPAs functioning and policy decisions. Gaps derived from the management and policy responses in the MPAs were also outlined. It was concluded that the DPSIR framework can help to simplify the complexity of MPA management. This document is a tool for policy makers, scientists and general public on the relevance of indicators to monitor changes and MPAs management.
