What is is?
AUSA is short for Aquarium USA magazine. A long-standing American yearly Annual magazine.
"Aquarium USA aims to help beginning to intermediate fishkeepers get started on the right foot."
This magazine is apparently now defunct. The latest edition I could find was 2010. FishChannel also seems to be defunct as the link below does not work.
No longer in existence.
