Water restoration for 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.
The problems we see on your water
What Alchemal installs and takes responsibility for
A hatchery lives or dies on stability. The animals are small, the stocking is dense, and dissolved oxygen (the oxygen dissolved in the water) that dips for a few hours at night can cost survival that no daytime reading would predict. Nanobubble oxygenation holds oxygen steady and continuous through the water, so the sensitive stages are not riding a curve that falls every night.
We baseline the oxygen profile before sizing anything, install the system matched to your tanks or raceways, and Stewardship logs dissolved oxygen continuously from there. The record is the profile itself, inflow to outflow and through the dark hours, measured against a baseline taken before any commitment. Where the real limit is flow or waste rather than oxygen, the assessment says so instead of selling you a system you do not need. The N-Series unit is matched to the site at the assessment, with a published target price band, and what we measure and how is published so the numbers you plan against are ones you can check.
Proof from hatchery managers
The first installations for this audience are being instrumented now, and their case files publish when the record is worth reading. The methodology is already public: what we record, how we calibrate, and how we report what didn't move.
From your first note to the assessment
- You describe the water. A specialist reads it, replies with a plain answer, and says whether an assessment makes sense.
- Your water goes on the schedule. The first assessments and installations are being scheduled now; requests are answered in the order they arrive.
- The assessment puts a baseline on paper: dissolved oxygen top to bottom, clarity, the condition of the sediment, and a plan with a prediction attached. If oxygenation isn't the right fix, the report says so.
Questions hatchery managers ask
Do you work with flow-through and tank systems?
Yes. We baseline dissolved oxygen through the system, inflow to outflow and across the tanks, then size the system to hold it steady at the stocking you run. The measured profile, not a rule of thumb, sets what goes in.
Is steady oxygen as important as high oxygen at early stages?
Often more so. Early life stages are sensitive to swings, so a continuous supply that does not dip through the night matters as much as the peak reading. Because the effect is measurable, Stewardship logs it rather than leaving it to impression.
How disruptive is installation to a running hatchery?
The system installs alongside what you run and holds a base supply from the start. There is no shutdown to plan around, and nothing is added to the water except oxygen.
