Essentially every naval unit, in it's description, says something along the lines of "if you wish to become Thelasotkia (Not sure the exact term) then you must build many of these" now you could just dismiss this but the description is present in many naval units implying that there is a way to stop pirates from spawning.

I wasn't sure if it was if your fleet needed to be a certain size, or you needed to destroy a certain amount of victories at the sea.
