Interactions of Patagonian Toothfish Fisheries With
CCAMLR Science, Vol. 17 (2010): 179–195 INTERACTIONS OF PATAGONIAN TOOTHFISH FISHERIES WITH KILLER AND SPERM WHALES IN THE CROZET ISLANDS EXCLUSIVE ECONOMIC ZONE: AN ASSESSMENT OF DEPREDATION LEVELS AND INSIGHTS ON POSSIBLE MITIGATION STRATEGIES P. Tixier1, N. Gasco2, G. Duhamel2, M. Viviant1, M. Authier1 and C. Guinet1 1 Centre d’Etudes Biologiques de Chizé CNRS, UPR 1934 Villiers-en-Bois, 79360 France Email – [email protected] 2 MNHN Paris, 75005 France Abstract Within the Crozet Islands Exclusive Economic Zone (EEZ), the Patagonian toothfish (Dissostichus eleginoides) longline fishery is exposed to high levels of depredation by killer (Orcinus orca) and sperm whales (Physeter macrocephalus). 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. -
Conservation Problems on Tristan Da Cunha Byj
28 Oryx Conservation Problems on Tristan da Cunha ByJ. H. Flint The author spent two years, 1963-65, as schoolmaster on Tristan da Cunha, during which he spent four weeks on Nightingale Island. On the main island he found that bird stocks were being depleted and the islanders taking too many eggs and young; on Nightingale, however, where there are over two million pairs of great shearwaters, the harvest of these birds could be greater. Inaccessible Island, which like Nightingale, is without cats, dogs or rats, should be declared a wildlife sanctuary. Tl^HEN the first permanent settlers came to Tristan da Cunha in " the early years of the nineteenth century they found an island rich in bird and sea mammal life. "The mountains are covered with Albatross Mellahs Petrels Seahens, etc.," wrote Jonathan Lambert in 1811, and Midshipman Greene, who stayed on the island in 1816, recorded in his diary "Sea Elephants herding together in immense numbers." Today the picture is greatly changed. A century and a half of human habitation has drastically reduced the larger, edible species, and the accidental introduction of rats from a shipwreck in 1882 accelerated the birds' decline on the main island. Wood-cutting, grazing by domestic stock and, more recently, fumes from the volcano have destroyed much of the natural vegetation near the settlement, and two bird subspecies, a bunting and a flightless moorhen, have become extinct on the main island. Curiously, one is liable to see more birds on the day of arrival than in several weeks ashore. When I first saw Tristan from the decks of M.V. -

ABSTRACT Percentage frequencies of diatom taxa from 20 levels in a sediment core from Kerguelen Island, Southeast Indian Ocean we~e considered in light of known present ecological preferences, and populations at varying levels compared. By using diatoms as environmental indicators, and also consider- ing physical stratigraphy, environmental conditions prevailing on Kerguelen during the past 10, 000 years were reconstructed. Comparisons we~e also made between depositional environment information determined by diatom studies and conclusions reached by Young and Schofield in a 1972 pollen analysis using soil samples from the same levels in the Kerguelen core • • I I • ii ACKNOWLEDGMENTS I would like to thank Dr. Gary B.

Based on new hydroacoustic data, we propose that the most recent hot spot volcanic 1234567890():,; activity occurs west of the island. We surveyed relatively young intraplate volcanic fields and scattered, probably monogenetic, submarine volcanoes with multibeam echosounders and sub-bottom profilers. Structural and zonal GIS analysis of bathymetric and backscatter results, based on habitat mapping algorithms to discriminate seafloor features, revealed numerous previously-unknown volcanic structures. South of Tristan da Cunha, we discovered two large seamounts. One of them, Isolde Seamount, is most likely the source of a 2004 submarine eruption known from a pumice stranding event and seismological analysis. An oceanic core complex, identified at the intersection of the Tristan da Cunha Transform and Fracture Zone System with the Mid-Atlantic Ridge, might indicate reduced magma supply and, therefore, weak plume-ridge interaction at present times. 1 Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Am Alten Hafen 26, 27568 Bremerhaven, Germany. 2 Faculty of Geosciences, University of Bremen, Klagenfurter Str. 4, 28359 Bremen, Germany. 3 MARUM—Center of Marine Environmental Sciences, University of Bremen, Leobener Str. 8, 28359 Bremen, Germany. 4 CNRS-UBO Laboratoire Domaines Océaniques, Institut Universitaire Européen de la Mer, 29280 Plouzané, France. -

This framework will allow the impact of threats on seabird populations to be qualitatively assessed, and will be used to prioritise a programme of seabird population monitoring. As a first stage in developing the framework, a database of demographic parameters and threats was prepared. In this project, a process was estab- lished for reviewing and synthesising this information. The demographic parameters were then used to develop an online tool, which allowed for the impact of changes in parameters on population growth rates to be assessed. In the future, this tool will allow the impact of current and potential threats on seabird populations to be promptly explored. The process was trialled on the 12 albatross taxa recognised
