In modern aquaculture, fish and shrimp ponds are often managed using high-density farming techniques. While this approach increases productivity, it disrupts the natural balance of the ecosystem. As a result, organic waste from uneaten feed, excretions, and dead plankton accumulates in the pond. These materials are not fully decomposed by other organisms and instead rely mainly on microbial action for breakdown. However, only a small portion of the nutrients in the feed is actually used by the fish and shrimp, with more than half becoming waste that pollutes the water and sediment.
At the beginning of the culture cycle, the pond has low biomass, limited organic matter, and sufficient dissolved oxygen. Aerobic bacteria break down organic material into carbon dioxide, water, and inorganic nutrients like nitrates, sulfates, and phosphates. These substances support the growth of algae, which in turn provide oxygen for fish respiration and help oxidize organic matter. This creates a healthy environment for aquatic life.
As the farming period progresses, the accumulation of organic matter increases. The decomposition process consumes oxygen rapidly, leading to anaerobic or facultative conditions. Harmful anaerobic bacteria then dominate, causing incomplete decomposition and the formation of toxic byproducts such as ammonia, hydrogen sulfide, and organic acids. These substances can damage fish and shrimp, leading to illness or even mass mortality.
To prevent this, it's essential to promote beneficial microorganisms in the water to outcompete harmful ones. This helps maintain a balanced ecosystem and improves overall water quality. Goldfish Fish and Shrimp Water Quality Conditioners have proven effective in enhancing water clarity, reducing sludge, and supporting a healthier aquaculture environment. By introducing these conditioners, farmers can create a more stable and sustainable system for raising fish and shrimp.
