1 Requirements for Breeding Environment and Deep-water Cage Installations 1.1 Deep-sea Cage Setting Environmental Conditions in the Sea Area The tide of the sea area is smooth with a flow rate of 0.5-1.0 m / s; the surface water temperature is 8-28 ° C with a small sudden change; the pH value is 7.6-8.6 ; The transparency is above 0.3 m; the dissolved oxygen is above 6 mg / L; the water depth is above 15 m; the wave height is within 5 m. The main water quality indicators should not exceed the safety requirements of fish culture and national water quality standards. 1.2 deepwater cages and supporting facilities require the use of deep-water cage materials have sufficient strength to withstand the impact of tidal currents and storms; effective use of less area loss, while ensuring fish
