| This study summarizes the results of the processing and analysis of data from illegal fisheries, apprehended by the eco-guards of the Marine Natural Reserve of Reunion from 2015 to 2017 (including the first dataset from 2018). These information are valued in terms of fisheries and bioecological knowledge for reef fish species. Thus, both diversity and abundance indices, size structures, growth parameters, stock characterization, can be apprehended from the biological parameters collected on all the species caught because they often do not exist : the sizes, weights, sexes, maturities, scales, otoliths, stomach contents as well as genetic and isotopic samples. These indices would contribute to a better diagnosis of the status and the sensitivity of stocks... |

| - The AMBIO project conducted a comprehensive video-based baseline assessment of coral reef fish communities and associated habitats in the New Caledonian lagoons. The surveys rely on remote unbaited underwater video observations, using the STAVIRO rotating technique. Chesterfield and Bellona remote reefs and atolls are located in the Coral Sea Marine Park, northwest of New Caledonia. -This 2013 survey is the first scientific survey covering the entire area, with a sampling design stratified according to reef type. 203 stations were validated within 10 days. They were analyzed to characterize the habitat surrounding each station, and fish communities, based on a list of 565 fish species (cf. AMBIO/A/1). - 34 indicators were computed and mapped (maps... |

| Les fonds coralligène constituent un habitat marin remarquable largement distribué dans la Réserve Naturelle de Cerbère-Banyuls. En 2015, un premier travail d'évaluation de l'état de conservation du coralligène a été réalisé par la méthode INDEX-COR. Les résultats ont montré notamment, la nécessité d'adapter les valeurs de références au contexte environnementale de la région de Banyuls, en prenant en compte notamment une plus grande diversité de stations et de faciès. Fort de ce constat, une nouvelle campagne d'acquisition a été réalisée en novembre 2018. Cette campagne avait un double objectif : (i) l'évaluation par l'indice INDEX-COR de l'état de conservation des formations coralligène dans la RNMCB et le suivi de son évolution sur le long terme et (ii)... |

| Coastal areas are complex socio-ecosystem where ecological, human and decisional compounds show multiple and reciprocal relationships. Because of the growth of population and tourism sector, coastal areas are permanently threatened through increase of recreational uses and diversification of related activities. To better understand coastal areas functioning, it is necessary to take into account uses and their management. Monitoring data over a ten years period revealed that recreational uses greatly increased especially within Marine Protecting Areas (MPA), during week-end days and warm season resulting to higher and more frequent frequentation peaks. While, practices within MPA are managed to decrease impacts, pressures associated with recreational uses... |

| Ce rapport constitue une synthèse des livrables des 3 actions de la convention PECHTRAD 2019 (n°19/1000 256). Ainsi, un soutien scientifique par une contribution aux réunions de médiation et de vulgarisation de la connaissance scientifique auprès des pêcheurs, des gestionnaires et des organismes d’Etat a été réalisé (action 1). La seconde action a synthétisé les résultats des analyses de l’évolution des efforts de pêche et des captures des différents métiers pratiqués par les usagers sur les platiers récifaux gérés par la RNMR en 2019. L’évolution des indices annuels de captures par unité d’effort a montré, une augmentation globale des abondances, aussi bien de capucins nains pêchés au filet, et des poissons ciblés à la gaulette, que des rendements de... |

| • In order to assess the sustainability of fish resources in the Natural Marine Park of Mayotte (Western Indian Ocean), indicators and monitoring protocols must be determined. • This study relied on the underwater video technique STAVIRO for assessing fish communities and resources. A pilot survey was conducted in Nov. 2014 in the south-east quarter of the Mayotte lagoon, an area encompassing the marine reserves of Longogori, M’Bouzi and the Saziley Marine Park. Out of 115 stations collected, 104 were analysed for habitat and fish, based on a list of 527 species with fishing, ecological, or emblematic interest (cf. AMBIO/A/1). • 43 indicators were computed, analysed, and for some mapped. The PAMPA computing tool was used in this purpose. • 130 fish species... |

| Antimicrobial peptides (AMPs) are natural antibiotics produced by all living organisms. In metazoans, they act as host defense factors by eliminating microbial pathogens. But they also help to select the colonizing bacterial symbionts while coping with specific environmental challenges. Although many AMPs share common structural characteristics, for example having an overall size between 10–100 amino acids, a net positive charge, a γ-core motif, or a high content of cysteines, they greatly differ in coding sequences as a consequence of multiple parallel evolution in the face of pathogens. The majority of AMPs is specific of certain taxa or even typifying species. This is especially the case of annelids (ringed worms). Even in regions with extreme... |
