  2. SEASONAL ESTIMATION OF ABUNDANCE BY BOOTSTRAPPING INEXACT RESEARCH DATA (SEABIRD): A METHOD FOR ASSESSING ABUNDANCE AND UNCERTAINTY FROM HISTORICAL COUNT DATA USING ADELIE PENGUINS AS A CASE STUDY

    Abstract:  In addition to a review of published studies on Adelie penguin abundance at breeding ... sites in Antarctica, Southwell (2004) proposed a general abundance estimator appropriate for a species ... of that kind. The present study attempts to implement this estimator in the form of a parametric ... uncertainty at breeding sites in Antarctica. To achieve this task, a menu-driven suite of routines titled ...

  3. A sensitivity analysis of a simple krill individual-based model designed to investigate length-based recruitment indices

    LFDs: growth, mortality and recruitment. Understanding how these processes interact is a prerequisite ... to the interpretation of any observed trend. To illustrate these interactions a simple mechanistic ... individual-based model of krill population dynamics was subjected to a sensitivity analysis. Starting from a ... , since the population size structure at a given time is the result of a mixture of several annual cohorts ...

  4. Developing and applying a general abundance estimator for land-based predator surveys: Adélie penguins as a case study

    Abstract:  The development of a general estimator of abundance would facilitate a standardised ... approach to regional and circum-Antarctic surveys of land-based predators. Such a generalised estimator is ... abundance of Adélie penguins at regional scales in Antarctica, given a range of logistical scenarios and ... related survey designs. Author(s):  C. Southwell (Australia) Title:  Developing and applying a general ...

  5. A revised estimate of short-term yield for the mackerel icefish (Champsocephalus gunnari) off Heard Island based on a trawl survey in 1998

    Abstract:  A random stratified trawl survey of Mackerel icefish in 2 populations (Plateau and ... Shell Bank) in the vicinity of Heard Island enabled a revised estimate of yield for the coming 2 seasons ... cohorts are still sufficiently strong to provide for a yield greater than estimates of the long term ... estimate of a long term precautionary level and be maintained thereafter unless a further survey again ...

  6. A brief review of information relevant to the establishment of a Krill Research Zone within the proposed Ross Sea Region Marine Protected Area

    Resources meeting in 2015, New Zealand and the United States introduced a revision to the proposed Ross Sea ... Region Marine Protected Area (RSRMPA) that included the addition of a Krill Research Zone (KRZ). A ... central aim of the proposed KRZ is to enhance research opportunities within the RSRMPA. To provide a ... , focusing primarily on krill and krill-dependent predators. Here we provide a summary of that review, which ...

  8. The error of the biomass estimate as a function of survey parameters and the statistics of a density field of krill aggregations

    estimate (by means of a survey) on statistical characteristics of fish concentration density field under ... methods of calculus of probabilities; biomass estimate is determined as a product of average density for ... a posteriori estimation of error made when calculating biomass, and for survey planning on the basis ... of a priori estimates of statistical characteristics of concentration density field. They might make ...

  9. A survey of fish stocks in the Heard Island and McDonald Islands region in the 1999/2000 season and a comparison of the abundances of selected species with those obtained in previous surveys

    Abstract:  A random stratified trawl survey was conducted in May 2000 to assess the abundance of ... stratum. A total of seven surveys have been conducted in the Heard Island and McDonald Islands region ... , varying by a factor of 2-3 between years, but C. gunnari abundance can vary by a factor of about 20 ... .
