A new aquaculture mode — the galvanized sheet PVC canvas pool

1 mm galvanized sheet is reinforced, rust-proof, aging-resistant and long-lasting. The circular support spreads stress evenly at every point, with double-layer pressing and waterproofing. Modular assembly uses double-row screw fixation — firm and durable. The blowdown bucket can rotate the whole pool for easy cleaning. The PVC knife-cut canvas inner wall is waterproof, sunscreen, corrosion-resistant, low-temperature-resistant, tasteless and harmless. Compared with traditional brick ponds it saves time and labor and costs less to build; it also prevents flood and pollution damage. Site requirements are low, management is easier, breeding efficiency higher, and uses range from fish, shrimp, leech and crab farming to industrial and agricultural water storage and even small household pools.
