MAKO – Movements, behaviour and conservation of South Atlantic shortfin mako sharks in a changing climate

MAKO – Movements, behaviour and conservation of South Atlantic shortfin mako sharks in a changing climate
Population assessments for shortfin mako sharks have showed that the North Atlantic (NAlt) stock is overfished and that overfishing is continuing. Satellite tracking data has also shown that mako space-use hotspots are highly targeted by fisheries, leading to an increased fishing risk in aggregation areas. However, most tagging studies are biased towards sub-adult makos causing an imbalance in estimated risk. Hence, key information on spatial distribution of key life-stages is limited. The proposed research aims to provide information on the movements and behaviour of large female (> 3 m) makos using satellite telemetry, to estimate the degree of overlap between shark hotspots and longliners in the South Atlantic (SAtl), and to explore how ocean climate change may impact habitat use patterns. Addressing these key questions is critical, particularly for the heavily exploited and data poor SAtl mako population, that is expected to continue declining for the next few decades.
