Dissolved Oxygen (DO) is the most important and critical water quality parameter because of its direct effect on the feed consumption and metabolism of shrimp as well as indirect influence on the water quality. Maintenance of adequate level of dissolved oxygen in pond water is very important to shrimp growth and survival. DO can be affected by many factors particularly water temperature, respiration of plants and animals and the level of organic matter. LaviFresh has applied for supplementation of excess dissolved oxygen and stabilizes the alkalinity levels in the pond environments. LaviFresh has formulated with special Calcium Perforates.
