This counter mould group ecological circulation aquatic products cultivating system includes cultivation unit, biofiltration unit and physical filtering unit totally three units.The water level of cultivation unit remains high compared with the water level of physical filtering unit； It include: separately the first straight Xiang Shuiguan, connection cultivation unit bottom and physical filtering unit bottom cultivates the principle that liquid level is equal in the linker that the water of unit is communicated according to bottom, is directly guided to physical filtering unit to water pipe through first automatically； Second straight Xiang Shuiguan is connected to physical filtering unit top and biofiltration unit top.The water of physical filtering unit is through second directly to water pipe overflow to biofiltration unit； Third longitudinal direction water pipe, bottom are connected to biofiltration unit bottom, top connection cultivation unit top.The equal principle auto-guiding of liquid level is to third longitudinal direction water pipe in the linker that the water of biofiltration unit is communicated according to bottom； And the aerator of what third longitudinal direction water pipe is set, the bubble for forming the water on third longitudinal direction water pipe top together with aeration is spilled over to cultivation unit.本貨櫃模組生態循環水產養殖系統包括養殖單元、生物過濾單元和物理過濾單元共三個單元。養殖單元的水位保持為較物理過濾單元的水位高；另包括：第一直向水管，其連通養殖單元底部和物理過濾單元底部，養殖單元的水根據底部相通的連通器內液面相平的原理，自動經第一直向水管導流至物理過濾單元；第二直向水管，其連通物理過濾單元上部和生物過濾單元上部。物理過濾單元的水經第二直向水管溢流至生物過濾單元；第三縱向水管，其底部連通生物過濾單元底部，頂部連通養殖單元上部。生物過濾單元的水根據底部相通的連通器內液面相平的原理自動導流至第三縱向水管；以及設於第三縱向水管的曝氣裝置，使第三縱向水管上部的水連同曝氣形成的氣泡溢出至養殖單元。
