1. 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 ...

2. 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 ...

7. An attempt to derive a composite index of abundance from acoustic surveys and fishery data

   Abstract:  Maps of krill (Euphausia superba) density derived from acoustic survey data and the ... distribution of fishing effort in the Chilean krill fishery indicate an area of high krill density wrapping ... around the northwestern end of Elephant Island during the austral summer of 1992. In this area, the ... distribution of catch-per-fishing-time and krill density (measured acoustically) show similar forms. Search ...
