Signs look out for:
While the majority (not all) of fishing vessels have poor working conditions, a vessel that has a crew that has been trafficked, conditions will be far worse. They will in most cases:
Emotional state of seafarers
Will be emotionally withdrawn
Will be afraid to communicate with outsiders
Displays fearful and anxious behaviour
Travel documents and contracts
to see their contracts (see if contract matches ship name)
To see their passports (in most cases the owner will not let the have or see it)
If they understand their contract (in trafficked victims, contracts are sometimes written in a language they do not understand.
When last they have received a salary
When last and/or have they communicated with their families.
My usual routine
When a fishing vessel comes into port, I will usually wait a 24 hours to board the vessel. If the crew and captain welcome me on board with open arms, I will usually just do the one visit. However if the I am not welcomed and get the idea that the owners/and or agents have something to hide, I will invite in the crew to the seaman's club, where I will attempt to build a relationship with the crew, to either dismiss or confirm my suspicions. If my suspicions are confirmed, I will contact the relevant parties.
(While most of these signs are accurate for and in our port, they might not be for others)
