Nausicaá is participating in the less involved ESB-European StudBook programme that tracks the stud of each animal within a population managed by the EAZA member institutions.
They concern the horn shark (Heterodontus francisci), the zebra shark (Stegostoma fasciatum), the sandbar shark (Carcharhinus plumbeus), the eagle ray (Aetobatus ocellatus), and the Klemmer's day gecko (Phelsuma klemmeri).
Knowing the genetic and demographic identity of the population is a valuable tool to monitor and manage each individual as part of a single population ex-situ.
The Atlantic nurse shark (Ginglymostoma cirratum), the epaulette shark (Hemiscyllium ocellatum), the sand tiger shark (Carcharias taurus), the starry smooth-hound (Mustelus asterias), the large spot stingray Potamotrygon falkneri, the ocellate river stingray (Potamotrygon motoro), the thornback skate Raja clavata, the spotted ray Raja montagui, the leopard shark Triakis semifasciata, and the nursehound catshark (Scyliorhinus stellaris) have joined even less restrictive MON-P or Monitoring programmes than the ESB.
