Gentlemen,
 
Is there a type of MOSFET which is normally 'on' with zero or low positive
gate voltage wrt source, but turns 'off' when Vgs is increased to a higher
positive 'threshold' value?

Reverse supply polarity and use a depletion NFET. (You’re basically asking
for a depletion PFET, but nobody makes them. )
