In the aquaculture industry, dissolved oxygen serves as a core factor affecting the survival and growth of aquatic organisms including fish, shrimps and crabs. Insufficient dissolved oxygen in water may cause farmed species to surface gasp for air, suffocate or even die. Conventional oxygen augmenting methods such as mechanical agitation and chemical oxygen addition often suffer from low efficiency and high costs. Under such circumstances, professional aquaculture oxygen generators have become critical equipment for improving farming returns. This article analyzes the core value of aquaculture oxygen generator suppliers from three dimensions: technical principles, key selection criteria and industry trends, helping farmers make well informed equipment choices.
