A risk management framework for avoiding significant adverse impacts of bottom fishing gear on Vulnerable Marine Ecosystems
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 ... used successfully by IMAF to minimise the effects of longline fishing mortality on seabirds. The aim of ...

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 ...

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 ...
