| Summary: | Abstract. Information from tagging and catches supports the model that fish of eastern and western origin mix on feeding grounds in the Atlantic. The paper discusses evidence that western fish have become increasingly vulnerable in recent years to fisheries east of the ICCAT stock division line, thereby confounding VPA assessment under the two stock hypothesis. The paper offers the suggestion that as a temporary measure the working group should recommend that catches made in the so-called Central Atlantic area be treated as western in origin. Such a recommendation would assist in capping the expansion of the ABFT fishery in the central and north east Atlantic until a better assessment can be made of the situation, and protect, to some extent the conservation efforts made in the west by readjusting the historical catch series. The effect of such a recommendation on the East would be minimal as the majority of the catches there come from the Mediterranean. A strong recommendation against the continuing unrestricted catches of undersize fish in the eastern Atlantic is warranted.
