Human Factors
On a passenger flight departing from ZZZ to ZZZ1; with a VERY inexperienced FO we neglected to put the sufficient amount of fuel on the aircraft for the trip.  The plan required about 4;000 lbs to land with about 1;000 lbs of reserve fuel.  When we were about 200 nm from the destination we got a low fuel light.  We advised ATC that we were low on fuel and required priority handling.  We were over water at the time.  So diverting was not an option.  Scary!!! We should have landed with about 1;000 lbs of reserve fuel.  Instead we landed with about 500 lbs of fuel!  Very embarrassing and humbling experience.I don't mean to reject responsibility.  But I distinctly remember asking the inexperienced FO prior to departing if everything was ready to go.  His answer was 'I don't know'...that should have been a sign of trouble.  In the future I will always ask the other pilot specifically he/she agrees we have enough fuel for the trip.
BE400 Captain reported that the aircraft departed with less fuel than was needed for the trip and got a low fuel light during cruise. The flight landed with less than the required amount of reserve fuel.
