An updated checklist of the marine fish fauna of Reunion Island, South-Western Indian Ocean ArchiMer
Letourneur, Yves; Chabanet, Pascale; Durville, Patrick; Taquet, Marc; Teissier, Emmanuel; Parmentier, Maurice; Quero, Jean-claude; Pothin, Karine.
The ichthyofauna of Reunion Island, Southwestern Indian Ocean, was sampled during several ecological and artisanal fisheries studies. Information from these investigations and from other sources were included to compile the present checklist of the marine fishes of the island. A total of 885 species belonging to 150 families was recorded. Nine species are known only from Reunion, indicating endemism of about 1.0%. The most speciose families (Labridae, Gobiidae, Serranidae, and Pomacentridae) were also among the most speciose at the neighbouring Mauritius Island (except gobiids), and, generally, on other islands in the Indian Ocean area (Maldives, Chagos, Madagascar and Christmas Island). The Gobiidae only represented 5.4% of the ichthyofauna, which was...

Assimilation of shrimp farm sediment by Holothuria scabra : a coupled fatty acid and stable isotope approach ArchiMer
Mathieu-resuge, Margaux; Le Grand, Fabienne; Schaal, Gauthier; Kraffe, Edouard; Lorrain, Anne; Letourneur, Yves; Lemonnier, Hugues; Benoît, Julie; Hochard, Sébastien.
Deposit-feeding sea cucumbers are efficient nutrient recyclers and have the potential to contribute to the limitation of organic matter load in polyculture or integrated aquaculture systems. Assessing how they assimilate organic matter originating from other farmed species is therefore important for the development of such multi-species farming systems. Here, a coupled stable isotope − fatty acid approach was used to characterize the assimilation of organic matter from shrimp (Penaeus stylirostris) farming by Holothuria scabra in an experimental culture system. H. scabra were reared in mesocosms on shrimp farming-originating sediment with and without additional food sources (maize and fish meals). Although fatty acid results did indicate that...

Behavioral and trophic segregations help the Tahiti petrel to cope with the abundance of wedge-tailed shearwater when foraging in oligotrophic tropical waters ArchiMer
Ravache, Andreas; Bourgeois, Karen; Weimerskirch, Henri; Pagenaud, Angélique; De Grissac, Sophie; Miller, Mark; Dromzée, Sylvain; Lorrain, Anne; Allain, Valerie; Bustamante, Paco; Bylemans, Jonas; Gleeson, Dianne; Letourneur, Yves; Vidal, Eric.
Two species breeding in sympatry are more likely to coexist if their ecological niches are segregated either in time, space or in trophic habits. Here, we combined GPS-tracking, stable isotope analysis and DNA metabarcoding analysis to understand how the rare Tahiti petrel Pseudobulweria rostrata (TP) copes with the very abundant (i.e. 500,000 breeding pairs) wedge-tailed shearwater Ardenna pacifica (WTS) when breeding in sympatry in a tropical area. WTS foraged in restricted areas along their path, while TP predominantly foraged using extensive search behavior, suggesting a more opportunistic foraging strategy. Interspecific overlap of foraging areas was higher than intraspecific overlap. Breeding seasons largely overlap between species during the study,...

Considering multiple-species attributes to understand better the effects of successive changes in protection status on a coral reef fish assemblage ArchiMer
Preuss, Bastien; Pelletier, Dominique; Wantiez, Laurent; Letourneur, Yves; Sarramegna, Sebastien; Kulbicki, Michel; Galzin, Rene; Ferraris, Jocelyne.
The response of fish assemblages to changes in protection status is a major issue for both biodiversity conservation and fishery management. In New Caledonia, the Abore reef marine reserve harbours more than 500 fish species, and has been subjected to changes in protection status since 1988. The present study investigates the impact of these changes on a wide subset of species (213), based on underwater visual counts collected before the opening and after the closure to fishing of this marine protected area (MPA). We analysed the spatial and temporal variability in fish assemblage attributable to protection status, explicitly considering habitat. To understand the successive responses of fish assemblage to fishing and protection, the assessment models...

Designing indicators for assessing the effects of marine protected areas on coral reef ecosystems: A multidisciplinary standpoint ArchiMer
Pelletier, Dominique; Garcia Charton, Jose; Ferraris, Jocelyne; David, Gilbert; Thebaud, Olivier; Letourneur, Yves; Claudet, Joachim; Amand, Marion; Kulbicki, Michel; Galzin, René.
The present paper aims at identifying and assessing indicators of the effects of Marine Protected Areas (MPAs) in coral reef regions, based on a bibliography review in ecology, economics and social sciences. First the various effects Studied within each of these domains and the variables used to measure them were censused. Potential ecological indicators were assessed through their link with the question used (here termed "relevance") and their "effectiveness" which encompasses the issues of precision, accuracy and statistical power. Relevance and effectiveness were respectively measured by the frequency of use of each indicator and the proportion of significant results in the reviewed articles. For social and economic effects, the approach was not...

Distribution spatiale des stocks de poissons récifaux démersaux d'intérêt commercial et effort de pêche en Province Nord de Nouvelle-Calédonie (Pacifique occidental) ArchiMer
Letourneur, Yves; Labrosse, Pierre; Kulbicki, Michel.
Fish from lagoon and reef in New Caledonia are mainly caught by artisanal fisheries and subsistence fishing. The present study aimed at estimating these fish standing stocks, at finding the main factors influencing the spatial distribution of these fish, and at estimating the maximum sustainable yield with considerations for socio-economic aspects sensu late. A total of 1406 stations was surveyed in the Northern Province of New Caledonia. Sampling was stratified according to three zones (north, east and west) and three biotopes (coral reefs, near-reef areas and lagoon bottoms). This work demonstrates the existence of important fish stocks of commercial interest in reefal and lagoonal waters of the Northern Province, estimated at about 138 300 t. The...

Distributions of Indo-Pacific lionfishes Pterois spp. in their native ranges: implications for the Atlantic invasion ArchiMer
Kulbicki, Michel; Beets, James; Chabanet, Pascale; Cure, Katherine; Darling, Emily; Floeter, Sergio R.; Galzin, Rene; Green, Alison; Harmelin-vivien, Mireille; Hixon, Mark; Letourneur, Yves; De Loma, Thierry Lison; Mcclanahan, Tim; Mcilwain, Jennifer; Moutham, Gerard; Myers, Robert; O'Leary, Jennifer K.; Planes, Serge; Vigliola, Laurent; Wantiez, Laurent.
Lionfish (Pterois volitans and P. miles) have become a major concern in the western Attantie and Caribbean since their introduction in the 1980s. Invasive lionfish can reach very high population densities on coral reefs in their invaded range, yet there are few data from their native range in the Indo-Pacific for comparison. We compiled data on the geographical distribution and density of Indo-Pacific lionfishes in their native ranges from published and unpublished underwater visual censuses and field collections. We found that lionfish in their native Indo-Pacific range are unevenly distributed, with higher densities in the Indian Ocean than in the Pacific. Lionfish densities increase significantly with increasing latitude, and are significantly higher in...

Effects of blue shrimp Litopenaeus stylirostris and goldlined rabbitfish Siganus lineatus in mono- and polyculture on production and environmental conditions ArchiMer
Trung Cong, Luong; Lemonnier, Hugues; Hochard, Sebastien; Royer, Florence; Letourneur, Yves.
This study was conducted to compare the effects of shrimp and rabbitfish in mono- and polyculture stocked at high biomass on production and environmental conditions in a mesocosm system. Shrimp (14 g) and/or rabbitfish (19 g) were stocked in four treatments with different density but with the same total biomass (236 g m−2), including shrimp monoculture (SM) (17 shrimp m−2), shrimp–fish polyculture (SF) (11 shrimp and 4 rabbitfish m−2), fish–shrimp polyculture (FS) (6 shrimp and 8 rabbitfish m−2) and fish monoculture (FM) (12 rabbitfish m−2). After 10 weeks of experiment, shrimp survival and biomass were low in the treatments where shrimp were dominant (SM, SF), while rabbitfish survival and biomass were high in all the treatments. Shrimp mortality was...

Feasibility of polyculture of blue shrimp Litopenaeus stylirostris and goldlined rabbitfish Siganus lineatus in a mesocosm system ArchiMer
Luong, Trung Cong; Hochard, Sebastien; Royer, Florence; Lemonnier, Hugues; Letourneur, Yves.
The study was conducted to (1) estimate the effects of polyculture of blue shrimp Litopenaeus stylirostris with goldlined rabbitfish Siganus lineatus on production, environmental quality and water and sediment metabolism and (2) to determine if blue shrimp and goldlined rabbitfish polyculture is possible. The experiment was carried out for 12 weeks in a mesocosm system that consisted of 12 circular outdoor mesocosm fiberglass tanks (1.7 m2, 1275 L water volume). Shrimp (2.9 g) were randomly stocked at density of 15 shrimp.m− 2 without rabbitfish (control), with rabbitfish (25.5 g) at low density (1.2 fish.m− 2) (LDRB) and high density (2.4 fish.m− 2) (HDRB). Results indicated that goldlined rabbitfish S. lineatus did not affect shrimp growth performance....

Fishers' perceptions as indicators of the performance of Marine Protected Areas (MPAs) ArchiMer
Leleu, Kevin; Alban, Frederique; Pelletier, Dominique; Charbonnel, Eric; Letourneur, Yves; Boudouresque, Charles F..
How users perceive the performance of Marine Protected Areas (MPAs) is fundamental for the social acceptance of these zones. Moreover, their perceptions may be relevant for monitoring the effects of MPAs on extractive activities. This study analyzes artisanal fishers' perceptions of the performance of a north-western Mediterranean coastal MPA, which encompasses two no-take zones (NTZs). Three viewpoints have been considered: the effect on the personal activity of fishers, the effect on the local fishery and the effect on the ecosystem. In order to test the hypothesis that biomass export (spillover) - which had previously been evidenced from the two NTZs - may influence fishers' perceptions of NTZ effects, fishers' perceptions were compared with both...

Flying to the moon: Lunar cycle influences trip duration and nocturnal foraging behavior of the wedge-tailed shearwater Ardenna pacifica ArchiMer
Ravache, Andreas; Bourgeois, Karen; Thibault, Martin; Dromzée, Sylvain; Weimerskirch, Henri; De Grissac, Sophie; Prudor, Aurélien; Lorrain, Anne; Menkes, Christophe; Allain, Valerie; Bustamante, Paco; Letourneur, Yves; Vidal, Eric.
Lunar phase and illumination are known to affect nocturnal behavior of many organisms, particularly through predator-prey interactions. Visual predators can benefit from higher light levels to increase their activity, while prey may decrease their activity to avoid predation. The lower number of nocturnal seabirds observed on colonies during full moon nights has been mostly interpreted as a predation avoidance strategy. However, it is also possible that shearwaters take advantage of the moon's illumination to feed also at night, and stay at sea to forage during full moon nights. We used miniaturized GPS-loggers to obtain 179 tracks from 99 wedge-tailed shearwaters breeding in New Caledonia, to investigate moonlight effects on individual behavior. Lunar...

Isotopic discrimination in helminths infecting coral reef fishes depends on parasite group, habitat within host, and host stable isotope value ArchiMer
Riekenberg, Philip M.; Briand, Marine J; Moléana, Thibaud; Sasal, Pierre; Van Der Meer, Marcel T. J.; Thieltges, David W.; Letourneur, Yves.
Stable isotopes of carbon and nitrogen characterize trophic relationships in predator–prey relationships, with clear differences between consumer and diet (discrimination factor Δ13C and Δ15N). However, parasite–host isotopic relationships remain unclear, with Δ13C and Δ15N remaining incompletely characterized, especially for helminths. In this study, we used stable isotopes to determine discrimination factors for 13 parasite–host pairings of helminths in coral reef fish. Differences in Δ15N values grouped according to parasite groups and habitat within the host with positive Δ15N values observed for trematodes and nematodes from the digestive tract and variable Δ15N values observed for cestodes and nematodes from the general cavity. Furthermore, Δ13C...

Métiers, effort and catches of a Mediterranean small-scale coastal fishery: The case of the Côte Bleue Marine Park ArchiMer
Leleu, Kevin; Pelletier, Dominique; Charbonnel, Eric; Letourneur, Yves; Alban, Frederique; Bachet, Frederic; Boudouresque, Charles F..
The overexploitation of fishery resources has led to a major fisheries crisis. In this context, artisanal fisheries, and in particular small-scale coastal fisheries, appear as relevant alternatives for a sustainable use of coastal resources. Marine Protected Areas (MPA) are more and more used as management tools for these fisheries, as protection effects and targeted access regulations may benefit to commercial fishers. Managers and scientists need then quantitative information not only to adapt their management to the fishing activity present on their territory, but also to estimate the effects of MPA management on it. This study provides catch and effort estimates that are essential for appraising and managing the artisanal fishery in the Côte Bleue...

Study seeks candidates for blue shrimp polyculture in New Caledonia ArchiMer
Luong, Cong Trung; Hochard, Sebastien; Royer, Florence; Lemonnier, Hugues; Letourneur, Yves.
Seasonal pathologies reduce the profitability and sustainability of the shrimp-farming industry in New Caledonia. A study was therefore conducted to estimate the effects of polyculture of blue shrimp with goldline rabbitfish or mullet on production performance and environmental quality. The fish did not affect shrimp production, and the combined shrimp/fish yields were significantly greater than the yield from shrimp monoculture. Changes in environmental quality in all treatments were few and minor throughout the culture period.
