    Abstract

    Monitoring of herbivorous fish populations and tracking management effectiveness for the newly established Turneffe Atoll Marine Reserve is poor due to several limitations of the existing data. Existing data on herbivorous fishes for the Atoll did not consider the newly established management zones of the Turneffe Atoll Marine Reserve and the number of sample sites was inadequate. Therefore, this paper aimed to provide baseline data for the newly established management zones of the Turneffe Atoll Marine Reserve. The herbivorous fishes mean biomass for the Turneffe Atoll Marine Reserve was 2454g/100m2. This figure fell in the FAIR category of the herbivorous fish abundance indicator of the Integrated Reef Health Index (IRHI). The mean biomass and density of the herbivorous fishes were higher for the general use zone than the conservation zones. Ocean surgeonfish had the highest mean biomass and density for the Acanthuridae populations while stoplight parrotfish had the highest mean biomass but striped parrotfish had the highest mean density for the parrotfish populations. The majority of herbivorous fishes were in the 11-20 cm size range for both the conservation and general use zones with means of 43 and 41 respectively. The general use zone had a higher amount of larger size herbivorous fishes in the size ranges 21-30cm and 31-40cm. Back reef habitats had the highest mean density while the shallow fore reef habitats had the highest mean biomass. The highest density for Acanthurids was found in the shallow fore reef habitats while the back reef habitats had the highest density of parrotfishes. However, the shallow fore reef habitats had the highest biomass for both Acanthurids and parrotfishes. Finally, the Kruskal-Wallis statistic for density and biomass for the management zones and habitats suggested that they were not significant and no real differences existed between them.
