Am I correct in assuming that how the DC 19 fortitude save was derived in regard to an aboleth's slime & mucus cloud being: the aboleth's CON of 20 minus its 8 HD plus its fort +7 (20-8=12+7=19)?

I don't know by heart, but the most frequent (99%) formula is 10 (base) +1/2 HD + Con Mod. That's 10 + 4 +5 = 19.

GawainBS is right, it's almost always Base 10 + half hit dice + ability modifier + misc modifiers.
