Analysis
NAICS 1125 is the 2022 industry group for aquaculture, part of 112 (Animal Production and Aquaculture).
It has only one more detailed code, 11251, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns does not cover crop and animal production, so there is no establishment count for it; farms are counted by the Census of Agriculture instead.
