AQUACULTURE
The looming issue of water scarcity poses a significant challenge to traditional aquaculture. As these systems, particularly ponds and land-based setups, demand vast water resources for operation, the increasing scarcity of freshwater can severely impede their productivity. Water shortages can lead to unhealthy fish conditions, disease outbreaks, poor growth, and mortality. Moreover, the competition for water resources between aquaculture and other sectors, such as agriculture and domestic use, heightens the threat. In this context, the sustainability and viability of recirculating aquaculture systems, which promise the delivery of fresh seafood like sushi with minimal water usage, become even More compelling.
- Traditional aquaculture can negatively impact the environment in several ways. It often leads to water pollution due to the release of waste products, uneaten feed, and chemicals into the water bodies. These effects can result in eutrophication, leading to harmful algal blooms that deplete oxygen levels in the water, harming aquatic life.
- Fish need adequate dissolved oxygen to breathe. If oxygen levels drop, they will come to the surface where the water usually contains the highest oxygen concentration. Numerous factors can lead to oxygen depletion, including excessive algae growth, decaying plant matter, or overcrowding of fish. Whatever the cause of the problem, adding a submerged aerator will immediately help reduce the stress and other adverse effects of low oxygen. The additional oxygen supply will keep them safe while you work on a more long-term solution.
- Poor water quality, due to accumulated waste, chemicals, or a recent algae die-off can also lead to low oxygen levels. Thus, leaving fish to seek relief at the water’s surface. High ammonia or nitrite levels can be particularly harmful to fish. Do a quick water quality test and consider performing a substantial water change if ammonia, nitrites, and nitrates are too high. Alternatively, a water conditioner can quickly bring the levels down.
One primary reason fish gather near the pump is the quest for oxygen. Pumps often act as a source of aeration, introducing dissolved oxygen into the water. If oxygen levels are low elsewhere in the pond, fish may instinctively swim toward the most oxygen-rich area, which can be around the pump. Overstocking, excess waste, high temperatures, or an imbalance of plants and algae can cause low oxygen.
A fishpond that emits a rotten egg smell may indicate the presence of hydrogen sulfide gas, which has that characteristic odor. Hydrogen sulfide is produced during the anaerobic (without oxygen) decomposition of organic material, such as fallen leaves, dead plants, and excess fish waste.
The deeper regions of your pond might not receive enough oxygen, leading to anaerobic zones where this gas is produced.
A buildup of sludge and sediment on the pond floor can foster anaerobic conditions, promoting gas production.
About the Aquaculture
Sept-X
Sept-X is a microbial-based water treatment product suitable for all aquaculture systems, including ponds, tanks, hatcheries, nurseries, and raceways.
Sept-X is a powerful microbial blend that improves water in aquaculture systems by accelerating the removal of nitrogenous wastes and promoting good water biology.
Sept-X supports optimum animal performance in all aquaculture systems.
Proven applications include algae control, nutrient management, odor control, and in-feed supplementation (in countries with regulatory approval).
