Water conditioner - a good helper in fishery
Water quality conditioners - a good helper for fisheries The basic status of fish and shrimp ponds at present: In fish and shrimp ponds, due to the adoption of high-density farming methods, the relative balance of natural ecosystems has changed, resulting in the excretion and remaining of fish and shrimps. Organic matters such as feed and plankton remnants have lost the chance of being transformed and utilized by other organisms, mainly relying on the decomposition and mineralization of microbes in the pool. Usually in a pond, only part of the feed fed is eaten by fish and shrimp, while only half or less than half of the nutrients fed in these feeds feed the growth of fish and shrimp, while more than half of the feed Becomes a variety of organic waste rowing tanks. Therefore, organic matter such as excrement of fish and shrimps, residual feed and plankton in the water are all accumulated in the culture ponds, causing serious pollution in the water and the bottom of the pond. In the initial stage of cultivation, the biomass in the pond is small, there are not many organic substances, and the dissolved oxygen is sufficient. Under the action of aerobic microbial decomposition, organic substances produce carbon dioxide, water, and inorganic salts such as nitrates, sulfates, and phosphates, which are single cells. Algae provide nutrition for photosynthesis, while unicellular algae provides dissolved oxygen for the respiration of fish and shrimps and the oxidative decomposition of organic matter, and creates a good color for the growth of fish and shrimp. At this time, the pond is in a relatively benign ecological balance. With the growth of the breeding period, there are more and more organic substances in the pond. The oxidative decomposition of organic matter quickly consumes dissolved oxygen in the water, making anaerobic or facultative. The anaerobic microorganisms grow in large numbers to become dominant bacteria (most of the anaerobic microorganisms are harmful), and the decomposition of organic matter is incomplete. It is easy to produce ammonia, organic acids, amines, hydrogen sulfide, lower fatty acids, alcohols, methane, etc. mid product. These products have poisonous effects on fish and shrimps, which can cause poisoning of fish and shrimp, and even lead to a large number of pathogenic microorganisms, causing illness and death of fish and shrimp. Therefore, how to increase beneficial microorganisms in the aquaculture water to form its population advantage to control the reproduction of anaerobic microorganisms is a problem that we need to consider. The goldfish fish and shrimp aquatic water quality conditioners have achieved good results in improving water quality and sediment conditions and creating a good culture ecology.
