  1. A method for inferring movement rates of fish from mark–recapture data

    Abstract:  This paper presents methods to infer the rate of movement of fish that are marked ... , released, and subsequently captured. The information that is available is the location and date of the ... release and the recapture. In addition, the intensity of fishing effort (i.e. sampling) by location and ... time is known. The simplest approach is to make a frequency plot of the distance between each release ...

  2. Population structure of icefish (Champsocephalus gunnari) in the South Georgia area (Antarctic)

    Abstract:  The living conditions of Champsocephalus gunnari in the eastern, western shelf areas of ... South Georgia and at Shag Rocks are different. The length-age structure of C.gunnari groupings ... inhabiting the areas at Shag Rocks and South Georgia is characterized with the lack of fish below 11 cm in ... length and older than 6-7 years (10-11 years in the South Georgia area) and considerably lower number of ...

  3. Population dynamics of the wandering albatross Diomedea exulans at Marion Island: long-line fishing and environmental influences

    breeding population of the Vulnerable wandering albatross Diomedea exulans. The numbers of birds breeding ... result of both real changes in the size of the population and changes in the proportion of the population ... influenced by both environmental and anthropogenic effects are described. The proportion of first-time ... survival rates of breeding adults were negatively correlated with Japanese pelagic longline fishing effort ...

  4. Sources of variability associated with Adélie penguin CEMP parameters measured at Béchervaise Island, East Antarctica

    we were able to for this paper may be useful because our estimates of temporal variability ... Abstract:  We examine the magnitude of a variety of sources of variability associated with CEMP ... weights, A5: duration of foraging trips, and A7: fledgling weights. Sources of variability can generally ... parameters at around 5-7% CV. The smallest source of variability was associated with measurement error ...

  5. Peculiarities of icefish Champsocephalus gunnari (Channichthyidae) distribution in South Georgia area during the surveys made by STM Atlantida in 2000 and 2002

    Abstract:  Reasons of differences in icefish distribution and biomass assessment during two ... surveys made by STM “Atlantida” are revealed. Availability of large icefish concentrations in 2000 in the ... northwest shelf area in 10-100m layer resulted in formation of adult fish aggregations in water column. The ... the bottom even in dark hours of the day. During the two surveys, fry and immature fish occurred in ...

  6. Atlas of coastal sea ice in eastern Antarctica

    Abstract:  The attached document provides information on an atlas of sea ice produced by the n. It ... vicinity of the CCAMLR Ecosystem Monitoring Program sites at Bechervaise Island near the Australian Station ... of Mawson, at Edmonson Point in the vicinity of the Italian Station of Terra Nova Bay and at Ross ... Island. The atlas is scheduled for release in August 2002. Here we provide a sample only of the contents ...

  7. Population dynamics of wandering albatrosses Diomedea exulans at sub-Antarctic Marion Island: longline fishing and environmental influences

    Abstract:  The Prince Edward Islands support the largest breeding population of the vulnerable ... Wandering Albatross Diomedea exulans. The number of birds breeding in this population has fluctuated over ... the past three decades and appears to be the result of both real changes in the size of the population ... and changes in the proportion of the population that attempts to breed in a given year. We describe ...

  8. The influence of environmental variables and mitigation measures on seabird catch rates in the Japanese tuna longline fishery within the Australian Fishing Zone, 1991–1995

    Abstract:  Long term fisheries observer data were used to analyse the influence of a range of ... environmental variables and mitigation measures upon catch rates of seabirds in the Japanese pelagic longline ... were set during summer, in southern areas of the zone, and during daylight hours. However ... , interpretation of changes in catch rates resulting from the use of mitigation measures or from weather effects ...

  9. Environmental variability and the behavioural dynamics of Antarctic fur seals in the South Atlantic

    Abstract:  Variability in the reproductive performance of marine predators may be a result of ... physical forcing by large-scale oceanographic variability. Time lags, remoteness from the epicentre of a ... physical process and the simultaneous action of multiple physical processes often mean that it is difficult ... to link variability in predator performance with specific measurements of oceanographic variability ...

  10. Entanglement of Antarctic fur seals (Arctocephalus gazella) in man-made debris at Signy Island, South Orkney Islands 1996/97

    Abstract:  The results of the first annual survey of entanglement of Antarctic fur seals at Signy ... Island, South Orkney Islands are reported for the 1996/97 season. Neck collars of man-made debris were ... seen on 12 seals, all of which were juvenile males. Five entangled seals were observed in an area ... around Signy Island Research Station where approximately 1.3% of the fur seal population come ashore. It ...
