# Aquaculture: who we serve

The work is the same on every water body, restore the oxygen and keep the record, and what changes is who you answer to.

- [Shrimp farmers A crash before dawn, a black bottom by mid-cycle, a feed bill that climbs while growth stalls. In grow-out the margin lives in the overnight oxygen, and one hot night can take a season's work. You want numbers, not adjectives, which suits us.](https://alchemal.com/aquaculture/who-we-serve/shrimp-farmers/)
- [Hatcheries In a hatchery the value per animal is highest and the tolerance for a bad night is lowest. Larvae and fingerlings feel a swing in oxygen before anything else does, and a few hours of low water can undo weeks of careful work.](https://alchemal.com/aquaculture/who-we-serve/hatcheries/)
- [Raceway operators On flow-through raceways the water arrives rich and leaves used, and the last pass runs the tightest margin. Carrying capacity is set at the lowest-oxygen point, and trout or catfish crowd it whenever a warm spell thins the source.](https://alchemal.com/aquaculture/who-we-serve/raceway-operators/)
- [RAS operators In a recirculating system the margins are tight and the biology is unforgiving. When the biofilter runs short of oxygen, ammonia creeps up and the whole loop feels it, and a water change spends the heated, conditioned water the design exists to keep.](https://alchemal.com/aquaculture/who-we-serve/ras-operators/)
