I know I am a bit late on this post but never late then never. I guess I will ask my first question of Samw. Is there a particular reason you are looking at feeding Brine Shrimp over another type of food like Rotifers?
If you do want to use brine shrimp then you would be looking at hatching them yourself to feed. You can go to the USA to order them but you can also get them from Canadian suppliers such as Mops (

As far a the capsulation process you may want to take a look at
