I think equipment will be hit the hardest, like all our pumps, filters, skimmers, and all the plastic bits and bobs we use. Tanks will also get more expensive, as China makes 29% of the world's glass, including most of our tanks. Livestock will be affected too, but probably at a lower rate. Tariffs on Indonesia and Thailand (two examples of countries where a lot of fish and corals come from) are at 32% and 36%. Given that aquaculture and mariculture are long-term operations and are heavily climate and region dependent, I doubt they will relocate to avoid tariffs.
