Abstract
    The fish assemblages of a temperate (Mira estuary, Portugal) and a tropical (Mussulo lagoon, Angola) seagrass beds were comparatively analysed based on the species composition, fish abundance and functional guilds. The species composition in the two assemblages was very different and the number of species recorded in the Mira site (47) was higher than that in the Mussulo site (18). The dominant fish families were the Syngnathidae, Gobiidae, Sparidae and Labridae in the Mira assemblage and the Haemulidae and Mugilidae in the Mussulo. Both assemblages were composed of a large proportion of species that use these estuarine systems as nursery areas. The percentage of resident species was higher in the Mira estuary. Considering the trophic guilds, for both areas, the benthophagous species were the dominant group. A comparative analysis of the abundance ranks of the fish families recorded in several seagrass bed assemblages worldwide reflected mainly biogeographical areas rather than seagrass habitat types.
