How to unlock the Master Gatherer achievement in BioShock 2 - Definitive Guide
You go through the little tutorial-ish-thing telling you to Hold X and follow the line, protect them while harvesting etc.
After you finish doing that, you have the ability to do that with any little sister you adopt. Do it enough and you'll get it. It doesn't matter if you rescue or harvest the little sisters only that you collect with them.
Just note; you don't have to collect with them. So if you really don't feel like doing it anymore after getting the achievement you can either harvest them on the spot or adopt them, take then to the vents, and choose to rescue/harvest them there. Having them gather/collect/what-ever-you-wish-to-call-it just gives you a higher ADAM intake.
Always up to you.
Once you adopt a Little Sister you can set her down next to glowing bodies to collect ADAM. A Little Sister can gather 40 ADAM from each body or 60 ADAM using the "Proud Parent" tonic.
Basic Gathering
As you start out you will need to harvest two bodies with each sister until you earn the "Proud Parent" Tonic.
8 Sisters with 2 bodies = 80 ADAM, 80x8=640
Proud Parent Tonic
You will be rewarded with this tonic after saving four Little Sisters. This will allow you to collect 60 ADAM per body rather than the previous 40 ADAM. If you harvest your sisters after gathering you may miss out on this tonic.
5 Sisters with 2 bodies = 120 ADAM, 120 x5 = 600
Depending on if you use the tonic or not you will earn this achievement either before or around Dionysus Park.
You can either use your map to find the ADAM or you can hold down the for a second and a trail will appear. This will lead to you the bodies that can be harvested.
Note: Saving/Harvesting a Little Sister does not count as a gather. Make sure you gather with each sister twice to avoid missing out on this achievement.
To unlock this achievement you will need to gather 600 ADAM during the Gather sequences. To be clear, this is specifically to 'Gather' the ADAM when you have adopted a Little Sister and not just a cumulative amount of ADAM earned.
See "Dealt with Every Little Sister" above for more details on gathering.

Not true. The trophy is cumulative. As soon as my sister pumped out the adam, I immediately poured it into Gatherers Garden.
Got a trophy in Siren Valley.
