Managing fisheries to conserve the Antarctic marine ecosystem: practical implementation of the Convention on the Conservation of Antarctic Marine Living Resources (CCAMLR)
We aim to identify the important steps in the evolution of the ecosystem approach to management under the Convention on the Conservation of Antarctic Marine Living Resources (CCAMLR). The first
Abrupt mid-twentieth-century decline in Antarctic sea-ice extent from whaling records

A decline in Antarctic sea-ice extent is a commonly predicted effect of a warming climate. Direct global estimates of the Antarctic sea-ice cover from satellite observations, only possible since the
The energetic cost of egg production in Antarctic krill ( Euphausia superba Dana)
Calculations indicate that multiple spawning by Antarctic krill in a season would require above average phytoplankton concentrations and filtration rates which are close to the maximum reported (> 10 1 kl).
Population structure and condition of Antarctic krill (Euphausia superba) off East Antarctica (80-150°E) during the Austral summer of 1995/1996
Krill larvae were moderately abundant in the survey area but were more frequently encountered in the east, which is probably a function of the lateness of the season when the larvae would be rising into the surface layer sampled by the net.
Tidier Fisheries Management Requires a New MOP (Management-oriented Paradigm)

    Reviews in Fish Biology and Fisheries
  • 1 September 1998
A management-oriented paradigm (MOP) crosses the boundaries of traditional fisheries scientific, economic and policy research and involves formulating management objectives that are measurable, specifying sets of decision rules, and specifying the data and methods to be used, all in such a way that the properties of the resultant system can be prospectively evaluated.
Changes in Antarctic sea-ice extent from direct historical observations and whaling records
Changes in the extent of Antarctic sea-ice are difficult to quantify for the pre-satellite era. The available direct data are sparse. A substantially larger set of proxy records based on whaling
Marine ecosystem-based management as a hierarchical control system
Although many jurisdictions have embraced ecosystem-based management for the marine environment, it is unclear what this entails in terms of both theory and practical action. I examine the management
Taking account of dependent species in management of the Southern Ocean krill fishery: estimating crabeater seal abundance off east Antarctica
Summary 1. The crabeater seal Lobodon carcinophaga is considered to be a key species in the krill-based foodweb of the Southern Ocean. Reliable estimates of the abundance of this species are
Uncommon or cryptic? Challenges in estimating leopard seal abundance by conventional but state-of-the-art methods
Abstract The method traditionally used to estimate pack-ice seal abundance employs sighting surveys from ships or aircraft to estimate the number of seals hauled out on the ice, combined with studies
Population dynamics of the wandering albatross (Diomedea exulans) on Macquarie Island and the effects of mortality from longline fishing
Mark-recapture analysis shows that the population of wandering albatrosses on Macquarie Island is not closed, and an annual number of longline hooks in the southern hemisphere tuna fishery of 41.6 million is calculated as the ceiling below which the population would begin to recover.
