The coral reef fish connumities of Saba Marine Park (Netherlands Antilles) and Hol Chan Marine Reserve (Ambergris Caye, Belize) in the Caribbean were studied to assess differences between them and adjacent ecologically similar sites after four years of protection from fishing. Forty-five percent of target species comonly recorded in visual census in Belize (23% of all recorded target species), and 59% at Saba (22%)., showed greater abundance, size or biomass in shallow protected sites. These differences are considered primarily to reflect increased survivorship with the cessation of fishing mortality. The greatest estimated biomasses were observed in locally protected snapper (Lutjanidae) in Belize and Saba, and grunt (Haemulidae) at Saba. In both protected areas the local stock of visible demersal target fishes was 1.9 to 2.0 times greater in biomass and 2.2 to 3.5 times greater in commercial value than in fished sites. Larger local stock of many target species is likely to support higher egg output from the protected areas, while larger predator biomass will mean more intense predation at the protected sites. This study generally focused on a fish counting methodology and the statistical analysis thereof. However, there is also included a snapshot of prices paid for various ranges of fish at the Caribena Cooperative in San Pedro, Ambergris Caye. The authors used these prices combined with relative frequencies of fish to estimate an average price paid per count of catch. Mean for the two fished sites was B$1.85/count (Belize dollars). Mean for the Hol Chan Marine Reserve was B$4.08/count. The mean value for fish caught at the Basil Jones Cut was B$2.96/count. The mean value of fish in families showing significant differences at Saba (snapper, grunt, grouper and parrotfish was B$1.48/count in fished areas and B$5.30/ count in the no fishing zone of the marine park.
