Social dynamics and individual hunting tactics of white sharks revealed by biologging Yannis P. Papastamatiou, Johann Mourier, Thomas TinHan, Sarah Luongo, Seiko Hosoki, Omar Santana-Morales, Mauricio Hoyos-Padilla ABSTRACT: Social foraging, where animals forage in groups, takes many forms but is less studied in marine predators as measuring social associations in the wild is challenging. We

Market incentives for shark fisheries
Market incentives for shark fisheries Ruth Beatriz Mezzalira Pincinato, Maria A.Gasalla, Taryn Garlock, James L. Anderson ABSTRACT: Fishers tend to prioritize landings of the most valuable product to better utilize vessel capacity. This may lead to discards of catches that are economically undesirable or legally prohibited. The high-value of shark fins and the low-value of
The need for long-term population monitoring of the world’s largest fish
The need for long-term population monitoring of the world’s largest fish Rohner CA, Venables SK, Cochran JEM, Prebble CEM, Kuguru BL, Berumen ML, Pierce SJ ABSTRACT: Many large marine species are vulnerable to anthropogenic pressures, and substantial declines have been documented across a range of taxa. Many of these species are also long-lived, have low
