Breeding technology Customer problem: There is a lot of green algae in the culture pond. The surface of the pond is almost covered. The water quality is not odor. The detection results show that the nitrous acid content is not too high. How is this going to happen and what should be done? Crown source reply: Reason: The pond is full of green algae, which is caused by the “eutrophication†of the aquaculture water and the excessive growth of algae. The reason may be as follows: 1. Before the pond was cast, the dry ponds and the clear ponds did not work. The organic matter left behind at the bottom of the pond was not completely oxidized and decomposed. 2. The feeding method was not scientific or overfeeding, resulting in water quality and bottom Deterioration of quality, excessive growth of algae; 3, the use of feed, the proportion of plant protein is too large, the soft-shelled turtle has a low use of plant protein, the protein is not absorbed by the soft-shelled turtle through the turtle's faeces into the water, causing water Pollution. Hazard: Overgrowth of algae in ponds can also lead to lack of oxygen in water bodies. Algae not only produce oxygen through photosynthesis but also consume oxygen. During the day, most of the algae will accumulate on the surface of the water to produce photosynthesis and produce oxygen. However, due to the dense growth of algae, the light cannot penetrate deeper waters. Therefore, algae in the surface layer of the water can produce oxygen through photosynthesis, and the water below the surface of the water. Algae consumes oxygen, which causes the surface of the water to be rich in oxygen while the deep water is in anoxic state. At night, both surface and deep algae are unable to use sunlight for photosynthesis, and only consume oxygen, the entire anoxic condition becomes even worse. Treatment: If the pond algae reproduce too much, you can use some drugs to kill algae (such as algae net, usually at noon), it should be noted that after using these drugs, some of the killed algae will sink to the bottom Since the algae corpses are also organic substances, they will also cause pollution to the bottom of the pool and cause oxygen deficiency in the water. Therefore, after the use of these algae-removing drugs, the water body should be oxygenated for 4 to 5 hours (usually using "granular oxygen" etc. Water body oxygenation agent), the algae corpse will float to the surface of the water body under the action of the oxygenating agent. Therefore, when the floating water surface is observed on the surface of the water body, the water in the surface layer of the water shall be promptly discharged out of the pond (can be placed on the water surface). In a bucket, the top of the bucket is slightly submerged in the water, and a pump is placed in the bucket so that the water in the surface of the water can be discharged out of the pond effectively. ã€Information above is for reference only】 For further communication, please add the QQ of our company's technical consultant Zhang.

Wealth Express Customer Name: Xu Yugen Customer Address: Dongyang Village, Daqiao Town, Jiaxing City, Zhejiang Province Investment time and seedling quantity: two batches of seedlings. The first batch voted 10,000 seedlings on July 20, 2009, and the second batch voted 10,000 seedlings on September 10, 2009. Breed species: Japanese wolfberry Breeding mode: Greenhouse, greenhouse transfer outside Tong Feed use: The “Crown Source†feed was used throughout the process. 3.2 tons of larvae and 3.2 tons of larvae were used in the greenhouse aquaculture process, and 3.7 tons of larvae were used in the aquaculture process. A total of feed of 10.1 tons of feed was used. Farming results and income: sold in two batches. On May 26th, 10th, when the greenhouse was transferred to Waitang, a group of turtles was sold. From June 26 to June 22, they grabbed more than 8,500 kilograms and sold for 20.5 yuan/kg, selling more than 170,000 yuan. All of the following 62 have been put on the outer pond to continue breeding, and were sold on December 13th, 10, and captured 9624 pounds. The EC goods were sold at 23.5 yuan/jin. Since the pool is not clean, it is estimated that it can sell about 10,000 yuan or so. About 220,000. Feed coefficient: 1.11 Customer evaluation: Although the price of "Guanyuan" feed is a bit high, but as long as you carefully calculate it, you will find that it is actually cost-effective to use "Crown Source" feed, which is a lot of money. After using this feed, I do not want to change other feeds at all! Wealth Hotline
