  7. 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 ...
