Summary
The susceptibility of several tropical algal species to fish grazing was studied on the Belizean barrier reef off the Caribbean coast of Central America. Short-term transplant experiments indicate that plant species vary markedly in their rates of biomass loss to grazing by a shallow-water guild of herbivorous fishes. Algal species transplanted from habitats with low grazing pressure are highly susceptible to grazing, while species occurring in habitats with high herbivore densities are highly resistant to grazing. Algal species show differential susceptibility to grazing by two major components of the tropical herbivore guild, Acanthurus (surgeonfishes) and Sparisoma (parrotfishes).
Variability in plant susceptibility to grazing by herbivorous fishes was not clearly correlated with morphological or chemical characteristics that have been previously suggested as plant defenses against herbivory. Plants found to be highly resistant to fish grazing, such as Halimeda, exhibit both morphological characteristics and secondary chemical compounds which do appear to reduce herbivory. In contrast, species of Caulerpa, Sargassum, Turbinaria, and Padina, which also possess alleged morphological and/or chemical defenses, are nevertheless highly susceptible to fish grazing.
