Scientific AdviceSingle-stock exploitation boundaries
The only new information available for these species is landings information and it is not sufficient to change the advice from 2006. The advice for 2009 and 2010 is therefore the same as the advice given in 2006: “Due to their spatial distribution associated with seamounts, their life history and their aggregation behaviour, alfonsinos are easily overexploited by trawl fishing; they can only sustain low rates of exploitation. Fisheries on such species should not be allowed to expand above current levels unless it can be shown that such expansion is sustainable. To prevent wiping out entire subpopulations that have not yet been mapped and assessed the exploitation of new seamounts should not be allowed.
