The population of the caprellid Metaprotella sandalensis Mayer (Crustacea: Amphipoda) associated with the seaweed Turbinaria ornata (Turner) J. Agardh was studied on a spatial scale in relation to the influence of physico-chemical factors on the coral reef system at Mauritius Island. Some areas of the coast of Mauritius are currently subject to disturbance due to industrialisation and rapidly growing tourist development programmes, meanwhile other sites of the island are still unaltered. T. ornata was sampled at 12 stations, distributed around the whole island to represent the heterogeneous conditions. The density of Metaprotella sandalensis living on T. ornata was measured. The linear regression and the multivariate analysis showed a strong correlation between the densities of the caprellid and the physico-chemical parameters. The highest densities of M. sandalensis were found in the most stressed sites characterised by the highest values of nitrate, phosphate, chemical oxygen demand and silting. According to these results and taking into account that M. sandalensis and T. ornata are widely distributed in most of the tropical ecosystems, we preliminarily propose usage of the density of this caprellid as a new monitoring tool on coral reefs or, at least, as a first diagnosis for the detection of nutrient enrichment on these ecosystems.
