Recently, the incidence of Penaeus vannamei in Lianyungang, Jiangsu Province has a very obvious characteristic:
1 concentrate in one area.
2 Mostly occur in shrimp ponds where water (groundwater) is not salinity.
The incidence of 3rd generation seedlings was much higher than that of ordinary seedlings. Therefore, individuals feel the cause of the disease:
The first is poor daily management. Such as: 1 basically no live mushroom preparations. 2 Feeds weigh 4 meals a day. 3 change to the bottom of the main use of bio-bottoms into the underlying anoxic. 4 Large amount of water causes aging or small amount of algae.
This results in red liver, liver atrophy, yellow and yellow foot, intestinal diarrhea and other diseases and algae is not prosperous (aerobic colorless or muddy water about 60 days of breeding), algae aging (sustained water in the water more matt ) Poor physical condition and bad environment together lead to hulliness.
The second is the softening of water, that is, the lack of trace elements such as calcium and magnesium.
The trace elements in freshwater and groundwater are relatively small. Therefore, groundwater is used for shrimp farming for a long time. The only trace trace elements that are captured after the growth of shrimp need to be supplemented are the lack of trace elements and the lack of shrimp resources. The use of trace elements in water is not conducive to the healthy growth of shrimp, resulting in the susceptibility of shrimp.
The third is related to abnormal cold weather in Jiangsu and Zhejiang this year. Because the external temperature is always low, it is not much raining. Generally, there are many cloudy days, causing the water temperature to never rise.
Fourth, farmers have more stocks of seedlings this year. Generation seedlings have higher requirements for the environment than ordinary seedlings. If the seedlings are raised in accordance with the management methods of ordinary seedlings, the possibility of failure is high.
Responses:
1 It is necessary to maintain the use of large bubble king + multi-dimensional fish and shrimp Rishi spices to regulate the health of the intestines. The purpose of this measure is to facilitate low-temperature food intake and strengthen the liver and intestines.
2 Water Quality Management: Use Shuangshui Ling Oxygen Bacteria every 7 days, use the Amino Acid viable algae + green algae source to keep the algae steady water every other day; use Fu Dian 6 bottles + Degradation Lingbao 6 packets every 7 days - 8 days The end of oxygen to protect the liver.
3 Use the source of Shencao An + Mei every 7 days to enhance the ability of the shell to absorb calcium and magnesium ions in the water to ensure that the shrimp shell is healthy and smooth.
Amino Acid
Another important function of amino acids is to provide energy to the human body. Normally, a healthy body on a general diet will use carbohydrates as its main fuel, but when the main source is depleted due to strenuous exercise, protein and amino acids can be used as a last resort. Amino acids also play an important role in food taste. Protein doesn't have much taste, but each amino acid has its own taste, and combining them is one of the important factors that define the taste of food
