Analysis of water quality requirements for yellow bone fish farming.
With the pursuit of healthy eating, fish has become a frequent guest on the table of more and more people. Among them, yellow bone fish is deeply loved by consumers because of its delicious meat and rich nutrition. However, in order to ensure the quality and yield of yellow bone fish, it is necessary to pay attention to the environment in which it grows - water quality. This article will analyze in detail the water quality requirements for yellow bone croaker farming.
First of all, yellow bony fish like to live in clear and transparent water. Therefore, the aquaculture water quality should be kept colorless, tasteless and odorless. Clear water quality is not only conducive to the life of yellow bone fish, but also conducive to farmers to observe the situation of fish and find and deal with problems in time.
Secondly, the yellow bone fish has certain requirements for pH value. The appropriate pH range is 65-8.5。Too high or too low can affect the growth and reproduction of yellow-boned fish. For example, a high pH can irritate the gills of a fish, making it difficult to breatheIf the pH value is too low, it will affect the enzyme activity in the fish and affect the metabolism.
In addition, the amount of dissolved oxygen is an important factor affecting the growth of yellow bone fish. Sufficient dissolved oxygen can maintain the normal physiological activities of yellow-bone fish and promote its growth and development. Generally, the amount of dissolved oxygen in the water is required to be more than 5 milligrams of liters. If the amount of dissolved oxygen is insufficient, it will lead to a lack of oxygen in the yellow bone fish, and in severe cases, it will even cause diseases and affect the yield.
In addition, ammonia nitrogen is one of the most common harmful substances in aquaculture, which has a great impact on the growth and reproduction of yellow bone fish. Therefore, the ammonia nitrogen content in the aquaculture water should be controlled at 02 mg liters or less. Ammonia nitrogen is mainly used for the decomposition of organic matter such as feed residues and fish manure, so regularly changing the water source and cleaning the bottom of the pond can effectively reduce the ammonia nitrogen content.
Finally, heavy metal ions such as copper, lead, mercury, etc. are toxic to yellow-boned fish, which can affect its growth and reproduction. Therefore, the concentration of heavy metal ions in aquaculture water should be lower than the standard limit set by the state. This requires rigorous testing at the time of water selection and regular water quality monitoring.
In summary, the water quality of yellow bone fish aquaculture requires clear, moderate pH value, sufficient dissolved oxygen, low ammonia nitrogen content, and low concentration of heavy metal ions. Only by meeting these conditions can we ensure the healthy growth of yellow bone fish and improve the efficiency of aquaculture. At the same time, this is what we as consumers look forward to, because we want to eat healthy and delicious yellow bone fish.
