Small herbivores suppress algal accumulation on Agatti atol
Original language description
Despite large herbivorous fish being generally accepted as the main group responsible for preventing algal accumulation on coral reefs, few studies have experimentally examined the relative importance of herbivore size on algal communities. This study used exclusion cages with two different mesh sizes (191 cm and 696 cm) to investigate the impact of different-sized herbivores on algal accumulation rates on the shallow (2 m) back-reef of Agatti atoll, Lakshadweep. The fine-mesh cages excluded all visible herbivores, which had rapid and lasting effects on the benthic communities, and, after 127 d of deployment, there was a visible and significant increase in algae (mainly macroalgae) with algal volume being 13 times greater than in adjacent open areas.The coarse-mesh cages excluded larger fishes ([8 cm body depth) while allowing smaller fishes to access the plots.
