Commercial Aquaculture Tanks — HDPE, PVC, FRP & Steel

Aquaculture Tanks

Commercial aquaculture tanks are the backbone of any land-based farm, and the right material depends on climate, stocking plan and how often the farm expects to move or expand. SIGMA manufactures all four mainstream types in-house: HDPE fish tanks for permanent installations, PVC canvas tanks for fast low-cost setup, FRP fiberglass tanks for hatcheries and indoor RAS, and galvanized steel tanks for large outdoor volumes.

Round tanks dominate fish farming because they self-clean toward a center drain, but rectangular fish tanks earn their place where floor space is tight or raceway-style flow is wanted. Every tank ships with the matching liner, drain fittings and — where the project calls for it — the aeration and filtration equipment to run it.
