Which element is crucial for maintaining water quality in aquaculture?

Dissolved oxygen levels are crucial for maintaining water quality in aquaculture because oxygen is essential for the respiration of aquatic organisms, such as fish and invertebrates. These organisms rely on dissolved oxygen in the water to survive and thrive. Adequate levels of dissolved oxygen promote healthy growth, reproduction, and immune function in aquatic species.

Oxygen levels can be influenced by various factors, including temperature, aeration, and the biological activity within the system. Without sufficient dissolved oxygen, aquatic animals can experience stress, reduced growth rates, and increased mortality, leading to negative impacts on production and overall health in an aquaculture setting. Monitoring and managing dissolved oxygen levels is therefore a fundamental aspect of ensuring a successful aquaculture operation.
