Fish Tanks — Circular, Raceway, Nursery Selection Guide
Tank choice defines hydraulics, waste self-cleaning, welfare and stocking flexibility. The right tank family depends on species behaviour, life-stage and cleaning strategy — not on vendor preference.
FishMatch Group is supplier-neutral. This page is educational content for buyers — not legal advice, not a supplier ranking.
Typical applications
- Circular self-cleaning tanks
- Raceways for salmonids and shrimp
- Nursery and quarantine tanks
- D-end and octagonal hybrids
Project sizes
- Small hatchery: $50K–$500K
- Commercial RAS: $500K–$10M
Selection criteria
- Self-cleaning velocity (typically 15–30 cm/s at fish level)
- Material: HDPE, GRP, coated steel, concrete
- Central drain design and dual-drain option
- Aeration and oxygen diffuser fittings
Questions buyers should ask
- What rotational velocity is guaranteed at my stocking?
- What is the dead-zone percentage?
- How does the drain handle mortalities without blocking?
Common procurement mistakes
- Choosing raceways for schooling species that prefer circular
- Ignoring dual-drain design for solids control
RFQ recommendations
- Publish hydraulic KPIs, not tank dimensions
- Include CIP and biosecurity in vendor scope
