| A diagnosis of recreational fisheries is carried out each year on the reef flat area of the Hermitage / La Saline managed by the Natural Marine Reserve of Reunion. The evolution of beach seine, fishing-rod and stick fishing activities, in terms of fishing effort and catch was analyzed. The status of exploited stocks differs according to the fishing technique. In 2018, the annual trend of catch per unit of effort indices showed 1°) an increase in the abundances of goatfish fished with beach seine, 2°) a relative stability with the fishing-rod practice and 3°) a constant decrease in octopus yields for stick fishermen. The honeycomb groupers size structure, targeted by fishing-rod fishermen, has improved. Octopus showed a decrease of larger specimens. Thus,... |

| The main objective of the CAMP project (2009-2011) was to estimate the effective connectivity between Marine Protected Areas (MPA) in the southwest Indian Ocean (SWIO) through population genetics of 3 biological models Epinephelus merra, Lutjanus kasmira and Myripristis berndti. The ultimate goal is to provide scientific results for managers to contribute significantly to the design of the MPA network in SWIO. At the end of the project and thank to the cooperation with the Natural Marine Reserve of La Réunion and 5 international partners from the SWIO, 414 M. berndti, 623 L. kasmira and 731 E. merra were sampled in 16 different sites (Reunion, Mayotte, Geyser, Europa, Juan de Nova, Glorioso, Rodrigues, Mauritius, Moheli, Grande Comore, Seychelles, Kenya,... |

| Epinephelus merra (Serranidae) is the most common and widespread species of this genus, mostly found in reef habitats from South Africa to Central Pacific. Thirteen polymorphic microsatellite loci were isolated and characterized from this species. Polymorphism was studied in two localities from the Comoros archipelago-Moh,li and Moroni. Allelic diversity was 7.5, polymorphism ranging from 3 to 13 alleles. Overall heterozygosity was high with an average observed heterozygosity of 0.587. Three of these loci were characterised by heterozygote deficiencies for both populations. Finally, ten of the 13 developed primers could be used in future population genetics study of E.merra that might be useful in a context of marine biodiversity conservation. |
