Is the recruitment of fishing boat crew reliable?

It is unreliable to recruit seafarers at sea.

First of all, sailors who go out to sea have to go through various trainings and finally get the standard certificate required by the maritime safety administration department before they can board the ship as seafarers. Therefore, some black-hearted intermediaries advertise everywhere, attracting job seekers to come to the door for consultation with high salaries, and then charging some fees to let job seekers go home and other news.
