Is the recruitment of fishing boat crew reliable?

It is unreliable to recruit seafarers at sea.

First of all, the crew who go out to sea have to go through various trainings and finally get the standard certificate required by the Maritime Safety Administration before they can board the ship as seafarers. Therefore, some "black-hearted" intermediaries distribute advertisements everywhere to attract job seekers to come home for consultation with high salaries, and then they will charge some fees to let job seekers go home and other news.
