  1. A risk management framework for avoiding significant adverse impacts of bottom fishing gear on Vulnerable Marine Ecosystems

    . This paper provides definitions of VMEs and summaries of their characteristics including natural agents ... adverse impacts of bottom fishing gear on Vulnerable Marine Ecosystems (VMEs) are avoided. Due to the high ... levels of uncertainty surrounding both the evidence of VME presence and the consequences of interaction ... with different types of gear, a risk management framework is proposed, similar to that which has been ...

  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 ... of that kind. The present study attempts to implement this estimator in the form of a parametric ... bootstrap model, utilising as input data published counts of Adelie penguins and estimates of their ... uncertainty at breeding sites in Antarctica. To achieve this task, a menu-driven suite of routines titled ...

  6. On acceptable scattering of longlines geo-referencing in the toothfish fishery in the CAMLR Convention Area

    Abstract:  The issues of longlines geo-referencing during the exploratory fisheries of the ... toothfish in the Convention Area are discussed. Cases of differences in the coordinates of settings and ... haulings are considered. The estimation of the maximum possible variation of the coordinates in the depths ... range of 550-3000 m was performed. It is shown that the differences of coordinates of settings and ...

  7. An alternative method for estimating the level of illegal fishing using simulated scaling methods on detected effort

    this new method are similar to those of the Agnew and Kirkwood (2005) method, and this suggests that ... the current method is adequate under circumstances of low evasion and when good knowledge exists that ... zero observations reflect zero illegal fishing. The new method performs better in the case of zero ... detections and can potentially better handle the evasion of detection by illegal activity. Both the new and ...
