Présentation Powerpoint Photo-Identification Catalogue Killer whales of the Crozet Islands 2003 - 2011 Paul Tixier, Nicolas Gasco, Cécile Roche, Christophe Guinet Centre d’Etudes Biologiques de Chizé - CNRS Villiers en Bois 79360 Beauvoir sur Niort CEBC-CNRS 2011 1 Killer whales of the Crozet Islands Austral and Antarctic French Territories Photo-Identification Catalogue 2003-2011 Paul Tixier, Nicolas Gasco, Cécile Roche, Christophe Guinet Centre d’Etudes Biologiques de Chizé - CNRS Villiers en Bois 79360 Beauvoir sur Niort CEBC-CNRS 2011 2 Preface This catalogue presents the frequently encountered killer whales that were photo-identified around the Crozet islands between 2003-2011. Pictures were taken and analyzed according to the photo-identification protocol developed in the NE Pacific by Bigg (1982). Priority was on left sides of the dorsal fin and saddle patch but for some individuals there were good pictures of the right side only. The edition of this catalogue was greatly based on catalogues produced by Bigg and colleagues (Bigg et al., 1987; Ford and Ellis, 1999; Ford et al., 2000) over the past 30 years. Pictures were taken from two distinct platforms: the Possession Island coastline, by the people working at the base Alfred Faure, and the seven Patagonian toothfish longliners allowed to operate within the Crozet EEZ, by the fishery observers. Two socially and morphologically distinct types of killer whales are observed in the Crozet waters: regular killer whales for which we have most of the data ( and the so called “Type- D” killer whales (Pitman et al., 2011) that have been sighted on few occasions only. The catalogue. In this catalogue, individuals are organized according to social relatedness. Social analysis were performed and association indexes were estimated using Whitehead (2009) methodology. Social units were given an unique code (upper left corner). This catalogue intends to assist in identification the different people encountering these whales.

From 2003 to 2008, sperm whales alone, killer whales alone, and the two species co-occurring were observed on 32.6%, 18.6% and 23.4% respectively of the 4 289 hauled lines. It was estimated that a total of 571 tonnes (€4.8 million) of Patagonian toothfish were lost due to depredation by killer whales and both killer and sperm whales. Killer whales were found to be responsible for the largest part of this loss (>75%), while sperm whales had a lower impact (>25%). Photo-identification data revealed 35 killer whales belonging to four different pods were involved in 81.3% of the interactions. Significant variations of interaction rates with killer whales were detected between vessels suggesting the influence of operational factors on depredation. When killer whales were absent at the beginning of the line hauling process, short lines (<5 000 m) provided higher yield and were significantly less impacted by depredation than longer lines.

  • Surface Temperature Field in the Crozet and Kerguelen Whaling Grounds
    SURFACE TEMPERATURE FIELD IN THE CROZET AND KERGUELEN WHALING GROUNDS SABURO MACHIDA Whales Research Institute, Tokyo ABSTRACT Some oceanographic conditions in the summer season at the surface in the Crozet and Kerguelen Ridge regions, where the good whaling grounds of baleen whales occur, are discussed on the basis of the distribution of the surface temperature observed by the Japanese whaling fleets in the 1965/66 to 1972/73 Antarctic seasons. The surface isotherms bend northwards over the submarine rising around the Prince Edward, Crozet and Kerguelen Islands. These bends of the iso­ therms suggest to reflect the bending of the surface current, and that it is presumably influenced by the bottom topography. They may be also sug­ gested that the convergence efficiency of the current is comparatively intense north and east of these submarine risings. INTRODUCTION It is well known that the good whaling grounds of baleen whales occur in the Crozet and Kerguelen Ridge regions. In these two regions right whales were taken by the old American whalers mainly in the 19th century and pigmy blue whales were also taken there in the early 1960's. Recently the Japanese whaling fleets have been often searching for the favorite haunts of the sei and fin whales in the regions. We have little knowledge of the general oceangoraphic conditions in the Crozet and Kerguelen whaling grounds, though the oceanographic conditions are the close living evnvironment to the whales. A knowledge of oceanographic conditions is fundamentally necessary to think systematic study on the environment of the habits of various marine organisms. From this point of view, therefore, the purpose of the present study is to discuss the oceanographic conditions at the surface in the Crozet and Kerguelen Ridge regions on the basis of the surface temperature distribu­ tion, which was observed by the Japanese whaling fleets.

  • National Involvement in the Indian Ocean Region
    5 December 2011 France: National Involvement in the Indian Ocean Region Bruno de Paiva Future Directions International Research Intern Indian Ocean Research Programme Key Points France has traditionally held a high degree of influence in the western Indian Ocean region and uses its cultural ties, external territories and military power to maintain its regional presence. The region is important to France, due to its strategic location and energy security needs. France’s regional influence is under threat from growing economies such as China, India and Brazil. While current French tactics will increase France’s influence in the Indian Ocean region in the short- and medium- terms, it is likely to lose influence over the longer term. Summary France has a long-standing presence in the western Indian Ocean. Despite the loss of its colonial possessions in India, Mauritius, Madagascar and the Seychelles, France retains the territories of La Réunion, Mayotte and the French Southern and Antarctic Territories. The former colony of Djibouti remains economically and militarily close to France, while relations with the United Arab Emirates have progressed to the hosting of a French military base in Abu Dhabi. For France, the Indian Ocean region – or, at least, its western reaches – continues to be of strategic importance. Over the longer term, however, the increasing interest in the region from growing economies, and the potential competition for resources and influence, may very well lead to a reduction in French influence. Analysis French Activities in the Indian Ocean Region Defence Much of France’s activities in the region have been defence related, with Paris operating a number of military bases in the region.

  • Population Trends of Penguins in the French Southern Territories
    Author's personal copy Polar Biology (2020) 43:835–850 https://doi.org/10.1007/s00300-020-02691-6 ORIGINAL PAPER Population trends of penguins in the French Southern Territories Christophe Barbraud1 · Karine Delord1 · Charles A. Bost1 · Adrien Chaigne2 · Cédric Marteau2 · Henri Weimerskirch1 Received: 31 July 2019 / Revised: 21 April 2020 / Accepted: 29 May 2020 / Published online: 3 June 2020 © Springer-Verlag GmbH Germany, part of Springer Nature 2020 Abstract Penguins are important top consumers in marine food webs and are one of the most threatened bird families, especially by climate change and food web alterations by marine fsheries. Yet, long-term population trends are lacking or are uncertain for many populations. Seven species of penguins breeding at the French Southern Territories in the southern Indian Ocean on the Crozet, Kerguelen, Saint-Paul–Amsterdam archipelagos and in Terre Adélie/Adelie Land, Antarctica are monitored regularly. This monitoring started in the early 1950s and most populations have been surveyed during the past four years, allowing assessments of population trends. King penguins increased at nearly all breeding sites within the Crozet and Ker- guelen archipelagos. Emperor penguins have decreased at Terre Adélie/Adelie Land, with a partial recovery of the colony during the 2010s. Gentoo penguin populations at Crozet and Kerguelen are highly variable but stable. Adélie penguins have been increasing in Terre Adélie/Adelie Land. The trends in eastern rockhopper penguins vary between colonies and archipelagos. Northern rockhopper penguins have continuously decreased in numbers at Amsterdam Island, but appear to have increased at the nearby Saint-Paul Island. Macaroni penguins have frst increased and then stabilized since the 2000s at Kerguelen and are stable at the Crozet Islands.
