High-density industrialized recirculating aquaculture and industrialized shrimp and crab seedling cultivation require continuously high dissolved oxygen water. Traditional aeration oxygen enrichment is insufficient in efficiency; liquid oxygen with purity ≥99.5% injected directly into the water can stabilize dissolved oxygen in the optimal range of 6-8mg/L, meeting the rapid growth needs of fish and shrimp.
Liquid oxygen aeration efficiency is more than 3 times that of traditional impeller aerators, aquaculture density can be increased by 2-3 times, and the survival rate of fish and shrimp increases by 20%; no floating-pond fish death occurs in hot and sultry weather; on-demand gas supply saves more than 60% of electricity compared with continuously running aerators.
