Eligibility applies to qualified business buyers and is confirmed after we review your product, quantity, destination, and sourcing requirements.
Application-led purchasing
Translate the culture stage and operating environment into equipment questions. The same tank volume can imply different treatment and monitoring needs when species, feeding and biomass assumptions change.
State the species and life stage, tank working volume, number of isolated groups and intended biomass basis. Ask how intake, drainage and cleaning arrangements separate groups. A shared water loop and independent loops have different operating and risk implications; equipment layout alone does not establish disease control.
Describe the planned stocking schedule and feed basis. Confirm how proposed solids removal, biological treatment and oxygenation respond to the stated range. Identify who tracks water conditions during loading changes and who approves departures from the commissioning assumptions.
Provide target standing biomass rather than only annual output. Include tank geometry, harvest access, available floor loading information and utility constraints. Request duty points for pumps and the acceptance basis for treatment; output targets are not supplier performance evidence.
These illustrative scenes identify inspection questions, not facilities owned by this service. Ask whether equipment can be isolated for cleaning, where sludge and makeup water go, and whether delivered dimensions fit the actual doorways. Keep site installation and transport constraints in the same brief as the tank and treatment specification.
A recirculating arrangement can support closer control of the water loop, but adds pumping, treatment, monitoring and emergency response responsibilities. Open pond or flow-through approaches may offer a simpler equipment scope where land and water conditions suit them, while exposing the project to different seasonal and discharge constraints. Compare measured site conditions and whole operating cost; no universal water-saving percentage is claimed.
Shared treatment can consolidate equipment and maintenance tasks. Independent loops can separate operating groups but duplicate some hardware and controls. Compare isolation boundaries, spare capacity, cleaning access and the consequences of a fault before treating either architecture as a cheaper equivalent.
Give the supplier a consistent species and feed basis, source-water results and proposed flow in m³/h. Request its calculations and duty points, agree a witnessed inspection method, then record actual test conditions and deviations against the written criteria. Validate site-specific obligations with the responsible project professional.
Consult the FAO system reference for terminology. Proceed to inquiry options with the application and US destination documented.
Send the species, biomass basis, treatment scope, quantity and delivery stages. Include installation and operating responsibility questions in your requirement.
