In the (race)_AI_fleets.txt file, you can set the number of fleets per number of ships. This is how to control the number of ships per fleet.

In practice you still will have very different fleet sizes: one or two huge fleets together with fleets that have only two or three ships. So in fact there is no direct minimum or maximum ship number in fleets specified.
