Human observers on tuna fishing vessels are required for certain gears and fishing vessels. Observers are not legally required on small scale vessels. As the Indonesian government rolls out its observer program, willing companies and vessels are accepting observers.
Legally small scale vessels ≤ 10GT are not required to have observers onboard. Electronic monitoring through cameras is seen as an opportunity for vessels not required to have obervers to transprently verify their activities at sea. This is specifically important with regards to proving non-interaction with Endangered, Threatened and Protected Species.
