The colonization of a fringing reef of Reunion Island by fish larvae takes place essentially from August to February with two peaks, in August-September, when the water temperatures are coldest, and in February when they are at a maximum. The number of fishes, as well as the number of sampled species, present similar values over two consecutive years with, nevertheless, a strong variation in the species involved. In Reunion Island, the number of post-larvae which colonise the reef is one hundred to four hundred times lower than on larger and more structured reefs. This phenomenon could be explained by the geographical characteristics of the island. The stock control of the adult fish in Reunion could largely be the result of the arrival of post-larvae on... |

The ichtyofauna of Geyser and Zelee coral banks (north of Mozambique canal) was investigated in 1996, this work being the first quantitative study on this area. Quantitative data were collected on 11 stations (mean depth 18 m) by visual observations along 50 m transect, widened to 2 m for small sedentary species, and to 5 m for commercial species with a large action range. The main descriptors of the fish communities (species richness, abundance per species) and the trophic structure (omnivorous, herbivorous, carnivorous, browsers of sessile invertebrates) were described and analysed.A total of 294 fish species, belonging to 43 families were recorded. The species richness varied from 45 to 83 species / station, and the abundance, from 292 to 1322... |
