Analysis
NAICS 112512 is the 2022 national industry for shellfish farming, part of 11251 (Aquaculture). Census lists 11 example activities under it in the official index.
Its index entries, the activities Census uses to assign businesses to this code, include clam production, farm raising, crawfish production, farm raising, crustacean production, farm raising and cultured pearl production, farm raising, among 11 in all.
Its goods appear in 14 statistical lines of the US tariff schedule, mostly under headings 0306 (crustaceans, whether in shell or not, live, fresh, chilled…) and 0307 (molluscs, whether in shell or not, live, fresh, chilled…). That link is how import data is matched to domestic producers, for example in trade-remedy cases.
For example, the catching or taking of shellfish from their natural habitat are classified in 114112 (Shellfish Fishing) instead.
Census lists 1 related activities that belong elsewhere, most often in 114112. Businesses that do several things are classified by their primary activity, the one that generates the most value, so check those boundaries before settling on this code.
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.
