It's not at all insinuated - it's right there in a hidden cut-scene at Quan's home. Quan was out on his pier 'fishing' into the Mist one day, and his line snagged Vivi, presumably off a passing airship as Kishi says. At first, Quan only kept Vivi because he thought the Black Mage would grow into a culinary curiosity, but he soon warmed to the little guy and raised him as family.

I don't quite recall how to view that cut-scene; I believe it involves visiting Quan's pier during disc 3, perhaps with Vivi and Quina in the party.
