Shark population monitoring tells us if conservation is working and is an early warning of failure. Yet shark population monitoring requires us to catch sharks, either directly (via fishing surveys) or remotely (via aerial or underwater video surveys), all of which are expensive and laborious. This study aims to compare shark numbers counted from the air with the concentration of their DNA left in the water in order to see if we can easily and cheaply estimate their numbers from DNA alone.
