Planning candidate

A cool-water species suited to oxygen-rich freshwater systems with long-cycle biomass planning.

• Active swimmer requiring stable water quality and suitable tank geometry.
• Commercial performance depends on stock, life stage and validated feed pathway.

The species is established in regional fisheries and is being evaluated for controlled aquaculture pathways.

Behaviour, stocking density and handling tolerance should guide tank layout, grading and transfer routines.

Hatchery, nursery and ongrowing stages have different temperature, flow, feed and biosecurity requirements.

Cool oxygen-rich freshwater with stable oxygen, solids control and stage-appropriate water quality.

Temperature

15–22 °C*

Salinity

Freshwater; typically below 2 ppt

pH

Validate by source water and life stage

Dissolved oxygen

Maintain a high, stable level with alarmed redundancy

Additional control focus

Temperature, ammonia, nitrite, alkalinity and suspended solids

Indicative planning bands only; validate the exact stock and life stage.

• Use a species- and life-stage-appropriate formulated feed.
• Set feed rate from biomass, temperature, water quality and observed response.

Nutrition and feed conversion require local validation.

Flow-through raceways; large circular tanks; cold-water RAS.

Cool-water RAS or flow-through raceways with dependable filtration.

Use approved hatchery seed or validated broodstock programmes.

Separate nursery zones support grading, biosecurity and low-stress transfer.

Size tanks, hydraulics, oxygen and solids capture around target biomass.

Automated or closely monitored feeding with response-based adjustment.

• Quarantine new stock and separate clean/dirty flows.
• Monitor oxygen, temperature, ammonia, nitrite and suspended solids.

Plan gentle capture, grading, chilling and transfer access.

Protect hygiene, temperature and product quality through organized handling.

Confirm target size, product format, buyer requirements and cold-chain route.

Interest is strongest where controlled systems can solve water, biosecurity and consistency constraints.

• Cool-water temperature control
• High oxygen reliability
• Long production cycle
• Continuous solids capture and welfare

• Design temperature control and oxygen redundancy as primary systems.
• Use bottom-drain or continuous solids capture for large circular tanks.
• Provide generous access for grading, welfare checks and harvest.
