Quantifying the escape mortality of trawl caught Antarctic krill (Euphausia superba) B.A. Krafft, L.A. Krag, A. Engås, S. Nordrum, I. Bruheim and B. Herrmann
Resumen:
Antarctic krill (Euphausia superba) is an abundant fishery resource, the harvest levels of which are expected to increase. However, many of the length classes of krill can escape through commonly used commercial trawl mesh sizes. A vital component of the overall management of a fishery is to estimate the total fishing mortality and quantify the mortality rate of individuals that Read More

Early analyses of CPUE in the krill fishery concluded that it was not a useful index of krill abundance. However, understanding the factors effecting the operation of the krill fishery and the extent to which these reflect changes in krill abundance are key elements of developing feedback management of the krill fishery. This analysis reviewed catch and effort data from the krill fishery for Read More

The marine ecosystem associated with the ocean shelves around South Georgia and the South Orkney Islands is highly productive, with a history of commercial exploitation. Many of the key oceanographic and ecological processes that determine the structure and functioning of this ecosystem operate over small scales of <10 km. Historically, these fine spatial scales have been poorly represented Read More

We review data on the breeding phenology of predators, and use data from the CCAMLR Statistical Bulletin (Version 28) to explore whether there are times of year that would reduce the Read More

We review the state of ecological knowledge for Subarea 48.2 and suggest that the development of any new management approach based on ecological indicators is limited by the current level of relevant ecological information. We propose that there is therefore an urgent need to improve the ecological knowledge base, but identify that this will take time. We conclude that if the krill fishery in Read More

Atlas of top predators from French Southern Territories in the Southern Indian Ocean K. Delord, C. Barbraud, C.-A. Bost, Y. Cherel,C. Guinet and H. Weimerskirch
Resumen:
Penguins, albatrosses, petrels, elephant seals and fur seals are marine top predators that have to come on land to reproduce. Therefore, they are the only marine top predators that can be studied from land base sites, making them the most accessible convenient models to study marine ecosystems. Indeed, seabirds and seals are considered as good indicators of changes in ecosystems at Read More

Growth and shrinkage in Antarctic krill Euphausia superba is sex-dependent G. Tarling, S. Hill, H. Peat, S. Fielding, C. Reiss and A. Atkinson
Resumen:
The ability of Antarctic krill Euphausia superba Dana to withstand the overwintering period is critical to their success. Laboratory evidence suggests that krill may shrink in body length during this time in response to the low availability of food. Nevertheless, verification that krill can shrink in the natural environment is lacking because winter data are difficult to obtain. One Read More

Parasites of the Antarctic toothfish (Dissostichus mawsoni Norman, 1937) (Perciformes, Nototheniidae) in the Pacific sector of the Antarctic I.I. Gordeev and S.G. Sokolov
Resumen:
The Antarctic toothfish (Dissostichus mawsoni Norman, 1937) is one of the main target species of commercial fisheries in the Antarctic. It is an endemic and is found along the shelf of Antarctica, as well as on the slopes of seamounts, underwater elevations and islands in the sub-Antarctic. It feeds on a variety of fish and cephalopods and can be an intermediate/paratenic host of some Read More

Southern right whale (Eubalaena australis) reproductive success is influenced by krill (Euphausia superba) density and climate E. Seyboth, K.R. Groch, L. Dalla Rosa, K. Reid, P.A.C. Flores and E.R. Secchi
Resumen:
The reproductive success of southern right whale (Eubalaena australis) depends on body condition and, therefore, on foraging success. This, in turn, might be affected by climatically driven change in the abundance of the species main prey, krill (Euphausia superba), on the feeding grounds. Annual data on southern right whale number of calves were obtained from aerial surveys Read More

Population trends and reproductive success at a frequently visited penguin colony on the western Antarctic Peninsula H.J. Lynch, W.F. Fagan and R. Naveen
Resumen:
Petermann Island (65°10'S, 64°10'W), one of the Antarctic Peninsula’s most frequently visited locations, is at the epicenter of a rapid shift in which an Adélie penguin dominated fauna is becoming gentoo penguin dominated. Over the course of five seasons, the breeding productivity of Adélie and gentoo penguins breeding at Petermann Island were monitored to identify drivers of this rapid Read More

A bioenergetics model for estimating prey consumption by an Adélie penguin population in east Antarctica D. Southwell, L. Emmerson, J. Forcada and C. Southwell
Resumen:
We developed a bioenergetics model to estimate prey consumption by the Adelie penguin. The model predicts prey consumption throughout the breeding season and incorporates uncertainty in model parameters using Monte Carlo simulation. The model was parametised with data obtained from the CEMP site at Bechervaise Island using 13 years of data, a year when penguins successfully reared chicks, and Read More

Resumen:
Reliable statements about variability and change in marine ecosystems and their underlying causes are needed to report on their status and to guide management. Here we use the Framework on Ocean Observing (FOO) to begin developing ecosystem Essential Ocean Variables (eEOVs) for the Southern Ocean Observing System (SOOS). An eEOV is a defined biological or ecological quantity, which is Read More

Resumen:
There is a substantial harvestfor Antarctic krill in the Southern Ocean, butlittle regular scientific monitoring of the resource. Recently, however, the Commission for the Conservation of Marine Living Resources (CCAMLR) has initialised a process to make use of acoustic data from commercial fisheries to increase the amount of relevant information available for making management decisions. We Read More

Demographic effects of extreme weather events: snow storms, breeding success, and population growth rate in a long-lived Antarctic seabird S. Descamps, A. Tarroux, Ø. Varpe, N.G. Yoccoz, T. Tveraa and S.-H. Lorentsen
Resumen:
Weather extremes are one important element of ongoing climate change, but their impacts are poorly understood because they are, by definition, rare events. If the frequency and severity of extreme weather events increase, there is an urgent need to understand and predict the ecological consequences of such events. In this study, we aimed to quantify the effects of snow storms on nest survival Read More

Large-scale oceanographic fluctuations drive Antarctic petrel survival and reproduction S. Descamps, A. Tarroux, S.-H. Lorentsen, O.P. Love, Ø. Varpe and N.G. Yoccoz
Resumen:
Polar Regions are experiencing environmental changes at unprecedented rates. ese changes can spread throughout entire food webs from lower trophic levels to apex predators. As many top predators forage over large areas, these indirect e ects may be associated with large-scale patterns of climate variability. Using global climate indices that are known to impact the Southern Ocean ecosystem ( Read More

Resumen:
Commercial fisheries may impact marine ecosystems and affect populations of predators like seabirds. In the Southern Ocean, there is an extensive fishery for Antarctic krill Euphausia superba that is projected to increase further. Comparing distribution and prey selection of fishing operations versus predators is needed to predict fishery-related impacts on krill-dependent predators. In this Read More

Resumen:
The condition and survival of Antarctic krill (Euphausia superba) strongly depends on sea ice during winter. How krill utilize sea ice depends on several factors such as region and developmental stage. A comprehensive understanding of sea ice habitat use by krill, however, remains largely unknown. The aim of this study was to improve the understanding of the krill's interaction Read More

Resumen:
Catch at length is an important input into any stock assessment. Consequently, collecting length data from the catch is a task undertaken by all at sea observes in CCAMLR fisheries. Although analyses in the past have looked to the optimal design of the observer program, in terms of levels of coverage of vessels and hauls (e.g., Agnew et al., 2009; 2010), less attention have been focussed on Read More
