Description : Volcano tourism plays an important role in the economies of volcanic islands in the Lesser Antilles. On islands like St. Lucia and Dominica these volcanoes have been utilized as geoparks and the areas even being designated as World Heritage Sites. In many of these islands, farming communities also live on the slopes to these volcanoes and with the increased pursuit of geothermal energy the siting of geothermal operations are also located in close proximity. Volcanic activity, therefore, has a significant impact on these islands at a local and national level. Many volcanomonitoring institutions face the financial and human resources challenge of providing ongoing monitoring services to economically burdened small island states. This has often led to the exploration of alternative low-cost monitoring options and strategies to be adopted by monitoring agencies. One such strategy is the adoption of a volcanic risk reduction approach to research and monitoring activities, which integrates the social and physical sciences through the engagement of local communities as partners with scientists in disaster risk reduction. We present a recent approach adopted using this type of strategy in St. Lucia and lessons learnt from this approach with implications for volcano tourism on island. The potential use of this strategy in Dominica is also presented, given the economic challenges the island currently faces during its ongoing recovery efforts from Hurricane Maria in 2017.

Résumé : At the outbreak of war with Spain in 1898, the U.S. Army was very small in numbers. This situation necessitated an immediate call for volunteers. President McKinley's appeal was overwhelmingly answered by a generation that had grown up in the shadow of their elders' Civil War glory. One group answering the call was the First Regiment of the U.S. Cavalry Volunteers, headed by Colonel Leonard Wood, a distinguished army doctor and Medal of Honor recipient. The regiment was actually the brainchild of Theodore Roosevelt, assistant secretary of the navy and Wood's friend. Roosevelt, realizing his own lack of military experience, suggested Wood for the command. The Rough Riders, as the regiment was soon known, comprised 1,250 men, including cowboys, Native Americans and eastern college athletes. Despite their dissimilarities, they were in excellent physical condition'a stark contrast to most of the other volunteer contingents. The Rough Riders departed from Tampa in mid-June without their horses. They landed at Daiquiri on June 22 and two days later served with distinction in a battle at Las Guásimas. Immediately prior to the conflict at San Juan, Colonel Wood was promoted to another field command, enabling Roosevelt as a full colonel to take command of the Rough Riders. On July 1, Roosevelt, having secured a horse, led his forces in a charge up Kettle Hill outside of Santiago. They achieved their goal and later in the day participated in the victory at San Juan Hill. By seizing these heights, American guns commanded the harbor at Santiago. The Spanish position was imperiled and an abortive attempt by the Spanish navy to escape from the harbor was halted with devastating results. Spanish land forces surrendered shortly thereafter. Roosevelt urged the Rough Riders' swift evacuation, fearing the continuing spread of disease. They returned to Montauk, Long Island, where they were held in quarantine before being mustered out in September. More than one-third of the Rough Riders were casualties in the Spanish-American War, a fact that has led some observers to criticize Roosevelt for unnecessary risk-taking. Nevertheless, the Rough Riders became heroes to the American public and Roosevelt emerged as a major national figure.

Résumé : Crayfishing is not particularly organized in the French islands as their population is not fond of large crustaceans. However, young crayfishes, about the size of the European scampi are ordered by rich Creoles for receptions or family gatherings. But lobsters, heavier than 0.750 to 1 kilo are eaten only by Europeans.Any fisherman who is asked to provide 10 kilos of crayfish catches them very quickly with a brass snare or a hook placed underneath the rocks. Some artisans gather the crustaceans in large rectangular baskets made of wire mesh and called "gardes", to wait for the potential customer. There is no specific pot for this type of fishing whereas Creole wicker makers worked hard on the creation of tools both complex and difficult to make to catch small morays; a fish which does not have a great commercial value.Consequently, it is impossible to precisely assess the importance of the exploitable large crustacean stock based on the catches of the Creole fishermen. If the performances of some crayfish boats from Douarnenez, using Mauritanian nets on the banks of St-Martin, can be considered as extremely satisfactory, it is not the case of other attempts. A whole study has to be undertaken. This note is only the beginning of a larger work focusing on the natural history of the crayfishes and Spanish lobsters in the waters of the arc of the Petites Antilles.
La pêche des langoustes n'est pas spécialement organisée dans les îles françaises, la population n'étant que peu friande de gros crustacés. Toutefois de jeunes langoustes, de la taille de la langoustine européenne sont commandées aux pêcheurs par les riches créoles, à l'occasion de réceptions ou de fêtes familiales; mais les « homards») dépassant le poids de 0,750 à 1 kilo sont consommés seulement par les Européens. Le pêcheur. auquel on demande de fournir 10 kilos de langoustes, les capture rapidement au collet de laiton ou au crochet sous les cayes, Certains artisans rassemblent les crustacés dans de grandes nasses rectangulaires de grillage métallique, appelées « gardes », en attendant l'acheteur éventuel. Il n'existe pas de type de casier spécial à cette pêche, alors que les vanniers créoles se sont ingéniés, par exemple, à créer des engins compliqués et difficiles à construire pour capturer les petites murènes appelées « moringues » qui n'ont pourtant que peu de valeur commerciale. Il est donc impossible de se faire une idée précise de l'importance du stock de gros crustacés exploitable en se basant sur les apports des pêcheurs créoles. Si les rendements de certains langoustiers douarnenistes, travaillant au filet mauritanien sur les bancs de St-Martin, ont pu être considérés comme extrêmement satisfaisants, il n'en est pas de même à propos d'autres tentatives. Il y a là toute une étude à entreprendre. Cette note n'est que le début d'un travail concernant l'histoire naturelle des langoustes et scyllares des eaux de l'arc des Petites Antilles.

Résumé : Selon le Consensus de Washington (1989), la Banque mondiale et les institutions internationales, la bonne gouvernance signifie la gestion saine du développement. L’objectif du présent article est d’analyser le lien entre bonne gouvernance et développement économique dans le cas des Etats insulaires. Après l’examen de la bonne gouvernance dans le cas particulier des Etats insulaires, nous utilisons la méthodologie de l’analyse en composantes principales afin de distinguer les caractéristiques institutionnelles et la gouvernance des économies insulaires selon leur niveau de développement économique.
According to Washington Consensus (1989), World Bank and international institutions, good governance means sound development management. The aim of this paper is to analyze the link between good governance and economic development in the case study of Island States. After the examination of the good governance in Island States, we use the principal component analysis in order to distinguish the institutional characteristics and the governance of the Island States in accordance with their level of development.

Résumé : L’objectif de cette étude est d’analyser les impacts et les limites d’une expérience de lutte contre la pauvreté par le tourisme au travers d’une étude de cas dans le village d’Anse-la-Raye, à Sainte-Lucie.Depuis son indépendance en 1979, Sainte-Lucie a tenté de diversifier la structure économique héritée de son passé colonial, en développant notamment des sources alternatives de recettes. Au début, il y a eu un certain succès avec l'industrie de confection et le tourisme qui ont émergé comme des activités viables en dehors de l'agriculture d'exportation.À la fin des années 1980, le pays avait même atteint un taux de croissance qui aurait été considéré comme raisonnable. Sainte-Lucie a d’ailleurs été l’île ayant connu la plus grande croissance économique des Etats du CARICOM. L’exportation de la banane a contribué pour beaucoup à ces résultats, et les nouveaux secteurs ont permis la création d’emplois ainsi que des revenus et des recettes d'exportation supplémentaires.Mais comme tous les Petits Etats Insulaires en Développement (PEID), Sainte-Lucie est caractérisée par sa vulnérabilité économique face aux catastrophes naturelles et crises extérieures. Ainsi, deux des secteurs principaux de son économie se sont affaiblis ces dernières années (l’agriculture et l’industrie), avec pour résultat principal une aggravation de la pauvreté à Sainte-Lucie malgré les bons résultats du secteur touristique devenu le pilier principal de l’économie de l’île.Dans ce contexte de faible croissance économique, le gouvernement et les partenaires sociaux se sont rassemblés pour identifier les politiques susceptibles d’accélérer la croissance économique de Sainte-Lucie. Ainsi, trois axes principaux ont été retenus : l’augmentation de la production locale, la réduction du crime et la réduction de la pauvreté. Dans ce dernier cadre, le gouvernement a lancé plusieurs stratégies de lutte contre la pauvreté notamment l’aide au développement d’activités touristiques.L’étude s’intéresse plus particulièrement au village d’Anse-la-Raye et à une expérience de tourisme pro-pauvre qui y a été développé en 2000 : l’Anse-la-Raye Seafood Friday, une sorte de festival qui permet aux visiteurs de déguster les produits de la mer tous les vendredis. Ce festival a-t-il eu réellement des répercussions sur la population pauvre de la communauté d’Anse-la-Raye ? Est-il viable? Quel est son devenir?
The objective of this study is to analyse the impacts and limitations of attempts to combat poverty using tourism through a case study in the village of Anse-la-Raye, in St. Lucia.Since its independence in 1979, St. Lucia has attempted to diversify the economic structure it inherited from its colonial past, in particular developing alternative sources of revenue. Initially there was some success with the clothing industry and tourism, which emerged as viable business activities outside of agricultural exports.At the end of the 1980s, the country had reached a growth which was considered reasonable. Of all the states of CARICOM, St. Lucia has moreover experienced the greatest economic growth. Banana exports have contributed significantly to these results, and new sectors have led to the creation of jobs and income to supplement export income.But like all Small Island Developing States (SIDS), St. Lucia is characterized by vulnerability to natural disasters and external economic shocks. Two major sectors of the economy have weakened in recent years (agriculture and industry), resulting in an increase in poverty in St. Lucia despite favourable outcomes in the tourism sector, which became the primary pillar of the island.In the context of low economic growth the government and social partners gathered together to identify policies and accelerate economic growth in St. Lucia. Three main themes were identified: Increasing local production; reducing crime and reducing poverty. In this context, the government launched several strategies to combat poverty including assistance for the development of tourism.The study focuses on the village of Anse-la-Raye and the experiences of pro-poor tourism that was developed in 2000: Anse-la-Raye Seafood Friday, a kind of festival that allows visitors to taste the seafood on Fridays. Has this festival really had an impact on the poor of the community of Anse-la-Raye? Is it viable? And what is its future?

Résumé : L’application de modèles macro-économiques à l’analyse et la conception de politique économique ainsi qu’à la maitrise des déséquilibres macro-économiques est encore à un stade précoce dans les petits états insulaires en développement. La présente étude tente de combler cette lacune en proposant un modèle macro-économique applicable à chacun de ces territoires et destiné à l’analyse, la prévision et l’impact de chocs sur leurs économies. La Dominique, petit État insulaire en développement de la Caraïbe, a été choisie comme étude de cas pour un tel exercice. Ce modèle s’appuie sur les techniques analytiques de la cointégration et du modèle à correction d’erreur. Les équations du modèle sont spécifiées et leur performance prévisionnelle évaluée. Une fois élaboré et estimé, ce modèle est ensuite utilisé à des simulations de chocs issues de scénarios alternatifs afin de fournir des enseignements sur la trajectoire future des principales variables économiques de ce pays. L’un des principaux scénarios de l’étude consiste à déterminer le taux de croissance économique que la Dominique devrait cibler pour atteindre l’objectif de réduction de la pauvreté de moitié d’ici à 2015 et ce, conformément aux Objectifs du millénaire pour le développement (OMD), et de déterminer la politique budgétaire et monétaire compatible avec cet objectif. Enfin, l’intérêt d’une telle étude réside dans le fait qu’elle peut servir à réaliser les cadrages macro-économiques des stratégies de réduction de la pauvreté. Sa flexibilité peut en faire un instrument de décloisonnement administratif, favorisant ainsi la discussion avec toutes les parties prenantes de l’élaboration des politiques économiques.
The application of macroeconomic models to analyse and conceptualize the economic policy, as well as controlling macroeconomic imbalances, is still at an early stage in small islands developing states. This article tries to fill in this gap by proposing a macroeconomic model for analyzing, forecasting, and testing the effects of shocks to the economy, applicable for each of these territories. The case of Dominica, a small island developing state of Caribbean area, has been approched. This model draws on the analytical techniques of cointegration and error correction. The single equations are specified and their forecasting performance is assessed. Then, the model is constructed and shock simulations are performed and different scenarios are developed to give further insight in the future path of the main economic variables.One of the main scenarios of this study will determine in comparison of Millennium development goals (MDG), the economic growth rate of Dominica which would help to attain the objective of reduction poverty in half by 2015, as well as the fiscal and monetary policy compatible with this goal. Finally, it helps to make macroeconomic frameworks for strategy reduction of poverty. Its flexibility serves to aid the discussion with all parties.

Résumé : The availability in interesting sites and the zootechnical performances of tropical fish are two impo rt ant assets in favor of the development of fish farming in the Caribbean islands. This repor presents a technical and financial analysis of red drum farming projects in floating cages in Martinique(French West Indies). This project analysis makes it possible to compare the economic feasability of a small-scale production system with that of a semi-industrial one submitted to different technical constraints. The main criteria of the project analysis are the profitability of the funded capital, the financial feasability during the buildup period, the profitability at a steady state and the cost price. Production costs are hi gher in the the small-scale enterprises than in the semi-industrial ones, thanks to better capita] productivity and better labour productivity. An analysis of sensitivity to the variations ofbiological and economical parameters is also contained in the report. The results of these studies indicate that Caribbean fish farming could be profitable, due to the rapid buildup of the facilities and to the short production cycles. Nevertheless, attention should be paid to the risk of storms and hurricanes in this part of the world. Moreover, the analysis of sensitivity highlights the great influence of seed price.

Les bonnes performances zootechniques des poissons tropicaux et la disponibilité en sites propices sont deux atouts majeurs favorables au développement de l'aquaculture de poissons dans les îles des Caraïbes. Ce rapport présente l'adaptation d'un outil de simulation technico- économique à l'éleva ge de l'ombrine en cages flottantes dans le contexte martiniquais. Cet outil permet de disposer d'éléments de comparaison sur la faisabilité de deux systèmes de production, Fun de type artisanal et l'autre de type semi- industriel, soumis à des contraintes techniquesdifférentes : rentabilité du capital investi, faisabilité financière au démarrage, rentabilité en année de routine, prix de revient. Une analyse de sensibilité des résultats aux variations de paramètres biologiques et économiques est également présentée. L'analyse de ces projets fait apparaître une rentabilité satisfaisante de l'activité, liée à la rapidité de mise en route des installations et à la brièveté des cycles de production. Line grande attention doit être cependant portée sur les risques d'accidents climatiques fréquents dans cette région du globe (cyclone, mais aussi tempête...). L'analyse de sensibilité montre la grande influence du prix d'achat de l'alevin, en particulier sur les résultats de la variante artisanale, dont le coût de production de l'ombrine rendue à quai, est plus élevé que celui de la variante semi- industrielle.

Résumé : Holothuria atra is the most common aspidochirotid holothurian on tropical Indo-Pacific reefs, Asexual reproduction by transverse fission, followed by regeneration, has been studied at Reunion Island (Indian Ocean) and compared with different populations of the Indo-Pacific zone, thus permitting a better identification of the most significant parameters and a better understanding of this reproductive strategy. At Reunion Island, the species is studied at two stations on the same fringing reef: 1) on the back-reef where the fission rate is high (20 % of the population), the individuals small (generally weighting less than 150 g) and the population density high (4/m(2)); and 2) on the reef front, where fission is extremely rare, the mean size of the individuals larger (up to 300 g) and the density low (0.01/m(2)), Different categories of individuals, fissioning (F), after fission, anterior and posterior parts (A and P), and regenerating (Ap and Pa) have been identified from external observations. Dissection has demonstrated the unequal allocation of organs during fission and the variability of the regenerative states, mostly in the anterior part. Concerning fission, the position of the split in an individual is in the anterior half (at 44 % of the total length). The monthly incidence of fission is higher from October to January and in June-July. Fission does not result in an increase in the density of the population. The monthly rates of regenerating individuals originating from anterior (3.7 %) and posterior (5.1 %) parts suggest that survival is higher in the latter instance. The occurrence of asexual reproduction in various populations of this species is discussed in relation to the ecology and the parameters of the populations considered. On the back-reef studied at Reunion Island, the population is subtidal and emersion cannot explain fission. Anthropogenic disturbances are possible triggers of this phenomenon.

Résumé : L’île caribéenne de la Dominique est une destination touristique émergente. Ce petit Etat, indépendant depuis 1978, situé entre les territoires français de la Guadeloupe et de la Martinique, entend développer un positionnement touristique original pour percer sur un marché régional prospère mais extrêmement concurrentiel.Le pays, relativement isolé, compte parmi les plus pauvres de la région et n’a pas suscité l’intérêt des investisseurs internationaux et sa charge de population est restée relativement stable depuis son indépendance (de l’ordre de 80 000 habitants en 2005 pour une superficie de 750 km²) en raison d’une émigration constante. C’est dans ce contexte que l’Etat dominiquais a construit sa stratégie touristique qui se fonde sur la mise en valeur de la singularité de ses ressources naturelles et humaines dans le cadre d’une planification territoriale qui vise à lutter contre la pauvreté.
The Caribbean island of Dominica is an emerging tourist destination. This small state, independent since 1978, located between the French territories of Guadeloupe and Martinique, intends to develop an original tourist strategy to break into a prosperous but highly competitive regional market.The country is relatively isolated and is among the poorest in the region. Dominica has not succeeded in attracting international investment, and its population has remained relatively stable since independence (about 80 000 people residing in an area of 750 km ² as of 2005) as a result of constant migration. It is in this context that the state of Dominica has constructed a tourism strategy based on the unique value of its natural and human resources in the context of spatial planning, which aims to fight against poverty.

Résumé : International audience
Assessing population connectivity is necessary to construct effective marine protected areas. This connectivity depends, among other parameters, inherently on species dispersal capacities. Isolation by distance (IBD) is one of the main modes of differentiation in marine species, above all in species presenting low dispersal abilities. This study reports the genetic structuring in the tropical hydrozoan Macrorhynchia phoenicea (sensu Postaire et al., 2016a), a brooding species, from 30 sampling sites in the Western Indian Ocean and the Tropical Southwestern Pacific, using 15 microsatellite loci. At the local scale, genet dispersal relied on asexual propagation at short distance, which was not found at larger scales. Considering one representative per clone, significant positive F-IS values (from -0.327*** to 0.411***) were found within almost all sites. Gene flow was extremely low at all spatial scales, among sites within islands (<10km distance) and among islands (100 to >11,000km distance), with significant pairwise F-ST values (from 0.035*** to 0.645***). A general pattern of IBD was found at the Indo-Pacific scale, but also within ecoregions in the Western Indian Ocean province. Clustering and network analyses identified each island as a potential independent population, while analysis of molecular variance indicated that population genetic differentiation was significant at small (within island) and intermediate (among islands within province) spatial scales. As shown by this species, a brooding life cycle might be corollary of the high population differentiation found in some coastal marine species, thwarting regular dispersal at distances more than a few kilometers and probably leading to high cryptic diversity, each island housing independent evolutionary lineages.

Résumé : Since 2000, the exploitation of the deep demersal fish (200-700 m) with the use of electric winches has been increasing in Reunion island ; and this has needed a new appraisal of yields (CPUE) and individual fish sizes, as indicators of the state of the fish stocks. A first survey has been carried out at the first half of 2011, in order to set up the comparison with a previous survey in 2000 on the West coast of Reunion island. Drops of yields and sizes could be pointed out, attesting the overexploitation of the commercial species (Fleury et al 2011). This present report displays the results of a second campaign, carried out in the second half of 2011 all around the island. 32 fishing trips have been conducted which have permitted 251 fishing operations. The overexploitation (i.e. decreasing of yields and fish sizes) has been confirmed in the West of the island, and in a lower stage in the North. Yields are better in the East and the South. As much as in the first survey, the small non commercial sharks (Squalus megalops) could be countered for half of the catches. At the same time, 2 hook sizes have been tested and the small hooks have displayed a better efficiency in number of catches but not in global weight. Various types of bait have been tested and meat of small local pelagic fish (Selar crumenophtalmus and Decapterus macarellus) have appeared to be the most efficient. This report provides helpful indicators for the management of fish stocks which have been poorly surveyed and poorly regulated till now.
Depuis 2000, la pêche aux poissons démersaux profonds (200-700 m) à l'aide de virelignes électriques s'est développée à La Réunion ; et le besoin se faisait sentir d'une évaluation des rendements (CPUE) et des tailles individuelles de capture, indicateurs halieutiques classiques des états de stocks. Une première campagne a été réalisée au 1er semestre 2011 pour établir la comparaison avec une campagne de prospection réalisée en 2000 dans l'ouest de La Réunion. Elle a mis en évidence des baisses marquées des rendements et des tailles de capture, signes d’une surexploitation des espèces commerciales (Fleury et al 2011). Ce rapport présente les résultats d'une 2e campagne de prospection étendue à tout le tour de l'île. 32 marées ont été réalisées permettant la mise à l'eau de 251 filages. La surpêche (baisse des rendements et des tailles de poisson) est confirmée dans l'ouest et à un moindre degré sur la côte nord. Les rendements sont meilleurs dans l'est et le sud. Comme dans la première campagne, les requins zépines (Squalus megalops), non commercialisés à La Réunion, représentent la moitié des captures. Parallèlement, 2 tailles d'hameçons ont été comparées et les petits hameçons ont donné une augmentation du nombre de captures, mais pas du poids global. Des comparaisons ont aussi porté sur les types d'appât et les laizes de petits pélagiques locaux (pêche-cavale et bancloche) se sont révèlées les plus efficaces. Ce rapport fournit des indicateurs utiles à la gestion de stocks jusqu'ici peu suivis, et peu encadrés.

Résumé : Some States host Open Registers (also known under the pejorative term of “flags of convenience”): ships are registered regardless of their actual owners’ nationality or residence, and thus States enable them to escape from their country of origin’s legal framework. By being an aspect of globalization, this phenomenon has been growing up for 30 years, and is nowadays widespread, or even universal. Because each State fixes the conditions for implementation of its right to register ships, the phenomenon is a legal one. But it has strong economic implications too. Indeed, the laws of the State of registration – namely “flag state” – determine certain costs or some advantages for the company that adopts it, and can be attractive or repellent as for them.This work proposes an economic reading of the open registers of ships as a recent object of economics and tries to highlight the contribution of this activity to small islands’ economies, especially through some Caribbean examples (the Caribbean is by the way the historical cradle of this activity and offshore financial centres).Based on data concerning the last 30 years and 7 open-registry countries of the Caribbean (Gross Domestic Products and some items of the balances of payments), the research conducted here shows that, except perhaps Antigua, no significant correlation exists in host countries between the fleets registered and the economic gains : the “open registration” is not, by itself, a gain for small island economies surveyed.
Certains Etats pratiquent la libre immatriculation, également connue sous le terme péjoratif de « pavillons de complaisance » : ils enregistrent des navires chez eux sans considération de la nationalité ou de la résidence effective des propriétaires, et leur permettent ainsi d’échapper au cadre légal de leur pays d’origine. Aspect de la mondialisation, le phénomène qui a pris de l’ampleur dans les 30 dernières années est aujourd’hui largement répandu, voire universel.Au-delà des aspects juridiques (chaque Etat organise son droit à immatriculer les navires), la libre immatriculation a des conséquences économiques fortes car la législation de l’Etat d’immatriculation – dit « Etat du pavillon » – détermine certains coûts ou certaines facilités pour l’entreprise qui l’adopte.Le présent travail propose une lecture de la libre immatriculation des navires en tant qu’objet récent de la science économique et tente, à ce titre, de lever le voile sur la portée de cette activité sur les pays d’accueil, en prenant le cadre restreint de petites économies insulaires de la Caraïbe, berceau historique de cette activité et des centres financiers offshore.Sur la base de données économiques sur 30 ans concernant 7 pays de libre immatriculation de la Caraïbe (produits intérieurs bruts et éléments des balances des paiements), la recherche menée montre qu’hormis peut-être le cas à approfondir d’Antigua, aucune corrélation significative n’existe entre le nombre de navires immatriculés et les gains économiques dans les pays d’accueil. Ces résultats vont dans le sens des critiques de la libre immatriculation : cette activité ne présente pas, en soi, un gain pour les petites économies insulaires étudiées.

Résumé : Situated in the north of the Mozambique Channel, Mayotte is the easternmost island of the Comoros Archipelago. From 1998 to 2005, Grande Saziley beach was monitored daily for green turtle Chelonia mydas nesting activity. Track surveys were monitored daily on 5 other adjacent beaches. Although nesting occurs throughout the year, nesting seasonality begins at the end of the wet season and intensifies during the dry season to reach an average nesting peak in June. In order to estimate the number of females nesting in the Saziley site and population trends over the study period, incubation success and number of nests per female and per season were estimated at 0.77 (±0.05 SD) and 3.03 (±0.37) respectively. With an average of 1545 nesting turtles per year (±439), the change in nesting numbers over the study period was so small that the population can be regarded as stable, with an estimated annual mean growth rate of 0.912, confirmation that this population is both stable and in good health. Added support for this argument is demonstrated by the fact that the annual carapace size distribution of nesting females is stable, meaning that the nesting green turtle population of Mayotte is not ageing or rejuvenating. After due consideration of data on other nesting sites in the southwest Indian Ocean, the data from Mayotte emphasizes the fact that the green turtle is not an endangered species in this region. Even if it is still illegally exploited and alterations occur in their different habitats, the green turtle populations of this region seem to have successfully survived all threats during the past century.
