Abstract Population genetics has been increasingly applied to study large sharks over the last decade. Whilst large shark species are often difficult to study with direct methods, improved knowledge is needed for both population management and conser

Abstract Severe food poisoning events after the consumption of sharks have been reported since the 1940s; however, there has been no clear understanding of their cause. Herein, we report for the first time the presence of ciguatoxins (CTXs) in sharks

International audience; The reproductive biology of the tiger shark Galeocerdo cuvier remains poorly documented because it is difficult to obtain data on a sufficient number of mature individuals to conduct appropriate analyses and thus to adequately

International audience; Sea cucumber populations are declining worldwide through overfishing. This is also the case for the greenfish Stichopus chloronotus in spite of its moderate commercial value. We studied asexual propagation of this fissiparous

International audience; Sea cucumbers are increasingly exploited for human consumption and for their cura-tive properties, and many wild populations are now depleted or in danger of extinction. While aquaculture is seen as an alternative to fisheries
