Movements, growth rates and strong sexual segregation in critically endangered tope sharks Galeorhinus galeus in the Northeast Atlantic.

ABSTRACT: The tope (Galeorhinus galeus, Linnaeus, 1758) is a critically endangered shark, which, like numerous elasmobranchs, faces severe global decline. There are, however, substantial disparities between this species' global conservation status and those of some local populations, with the Northeast Atlantic representing a relative stronghold for this species. However, several areas of uncertainty, particularly regarding individual movement patterns, currently hamper region-specific conservation efforts. Therefore, utilising capture-mark-recapture tagging data, collected predominantly by recreational anglers in Ireland - but with recaptures throughout the Northeast Atlantic and Mediterranean - we investigated regional population structure, spatial segregation and individual movement patterns, and
