Detailed Explanation of Key Technical Points for Shrimp Fry Stocking in Spring
1. After thorough pond disinfection, it is essential to splash Jiedu Lvshuibao or Hushui Jiedu Wang to neutralize and expel toxins. After 4 hours, splash compound Bacillus or Xinjunke combined with Heitujing over the entire pond (they must be soaked in water 4 hours in advance). This decomposes disinfected animal carcasses and other organic debris and converts them into nutrients needed for algae growth, which helps cultivate algae and fertilize the water, and cultivate bacteria to maintain water quality. Then choose a sunny morning with ample sunlight to fertilize the water. If conditions permit, add 10 cm of fresh algae-containing water to introduce algae species, or use Duozaoyuan to supplement algae species. Before fertilizing the water, turn on the aerator to make the water flow, which is beneficial for algae reproduction and growth. Fertilization: soak Qiangxiao Peizao Gao, Feishui Kele or Yizao Yingyangsu, Feishui Lishengsu in water for 4 hours before splashing. For ponds where water fertilization has failed or does not work for a long time, after filling with water, first use Hushui Jiedu Wang and Heitujing to purify the water, then after 4 hours use the above water fertilization products with Duozaoyuan to fertilize the water.</p><p>2. Most Litopenaeus vannamei (Pacific white shrimp) farmers believe that the first batch of shrimp fry is the best, and they all ignore weather conditions in order to grab the first batch of fry, even stocking fry at lower temperatures. If strong winds and cooling weather occur within two days after stocking, causing a sudden drop in temperature, the shrimp will have a strong stress response. Because the fry are relatively weak, this can easily cause fry mortality. Therefore, stocking fry requires patience. Wait for consecutive good weather to stock fry, and choose a sunny morning or evening. Before stocking, use Jiedu Lvshuibao or Hushui Jiedu Wang to remove toxins from the water, and splash VC Yingjiling and Fuhe Gaibao to improve the fry's stress resistance and promote molting. 3. When selecting shrimp fry, understand the qualification, commercial reputation and technical strength of the hatchery enterprise, such as whether the production of broodstock and seedlings is standardized, whether it meets national requirements, and whether antibiotics are used or high-temperature seedling production is carried out throughout the production process. When purchasing fry, whether the enterprise can present quarantine qualification certificates from relevant government departments to ensure the health of the shrimp fry is the primary condition for successful farming. 4. Maintain the stability of pond water. Too lean or too fertile water will cause oxygen deficiency. Choose excellent water fertilization products such as Qiangxiao Peizao Gao, Jiaosu Gaifei, Yizao Yingyangsu, Feishui Kele, Feishui Lishengsu, Duozaoyuan, etc. to cultivate high-quality algae and keep the water body fertile, lively, tender and refreshing. When the water is too fertile and too dense, appropriately exchange part of the water, use Jiangjie Wang to improve water permeability, and use microecological preparations such as compound Bacillus, Xinjunke, pure EM bacteria, etc. to maintain the balance of algae and bacteria in the pond water. Regularly use Heitujing combined with compound Bacillus, Yingji Di Jiankang and other substrate improvers to keep the pond bottom clean and prevent moss, giving the shrimp a good bottom environment. 5. Feed reasonably. The feeding time is about 2 hours. Check the shrimp's feeding situation while they are eating to avoid leftover feed or insufficient feed. Regularly add health nutritional products such as Fengxia Gaowen C, Mianyi Huoliyuan, Hugan Weibao, Kaiwei Putang, etc. to the feed to improve the shrimp's feeding ability and the body's disease resistance, and improve the intestinal tract. Especially during the juvenile shrimp liver transition period, Hugan Weibao, Fengxia Gaowen C, Mianyi Huoliyuan, etc. should be added. 6. Use drugs reasonably. When shrimp become sick, according to the incidence situation and symptoms, use drugs safely under the guidance of technicians, and try to avoid using highly irritating drugs or antibiotics. It is recommended to usually splash herbal antibacterial and detoxifying traditional Chinese medicine products such as Caoben Jundumie for prevention, and at the same time pay attention to regulating water and improving the bottom, maintaining excellent water quality and substrate environment.</p>

What to pay attention to when stocking fish fry in reservoirs in winter
Every winter is the golden season for stocking fish species such as silver carp, bighead carp, grass carp, and black carp into reservoirs. But quite a few fish farmers report that within 2 to 7 days after stocking the fry, large numbers of dead fish and swimming sick fish appear on the surface of the reservoir water; these fish lose their luster and their body surface mucus increases. Based on the above symptoms, it can be inferred that the fish have contracted a typical case of "acclimation sickness." This disease is mainly caused by a drastic change in water temperature, in which the nerve endings in the fish skin are strongly stimulated, causing dysfunction of the internal organs, and its death

Precautions for Spring Transport and Stocking of Fish Fry
Spring returns to the earth, water temperatures gradually rise, and it is once again the best time of year for transporting aquatic fry and fingerlings. During this period, because water temperatures are relatively low, fish are less active, and at the same time their bodies are firm and scales tight, so they are less likely to be injured during transport, which can increase the survival rate of spring stocking of fingerlings. There are many precautions in the spring transport and spring stocking of fingerlings, and fishermen friends are reminded to pay attention to them. 1. Pond disinfection should be carried out after removing excess sludge from the pond, reinforcing the pond embankment, and clearing the inlet and drainage ditches. Generally, for a dry pond, use about 200kg of quicklime per mu, slake it into a slurry, and

What are the pond-clearing methods? Remember these five before stocking fish fry
Before stocking fish fry, the aquaculture pond must be cleared to kill various predatory small wild trash fish, harmful aquatic animals and plants, parasite eggs, pathogenic bacteria, etc., creating a good environment for the growth of adult fish. The following five pond-clearing methods are introduced: 1. Clearing the pond with quicklime. When carrying out drainage pond clearing (that is, draining the pond water to a depth of 5-10 cm of remaining water before clearing), use 60-70 kg of quicklime per mu of pond; when clearing without draining, use 125-150 kg per mu of pond for every meter of water depth (200 ppm).

Key Technical Measures for Stocking Fish Fry in Winter
As the saying goes, "Stock fish fry in spring and they catch disease; stock fish fry in winter and they grow three fen." Practice has proven that the period from the Winter Solstice to the Start of Spring is the best time to stock fish fry. There are three reasons: first, the fry are plump and firm-scaled at this time, with strong adaptability. Second, the low water temperature weakens the fish's activity, resulting in a high survival rate during catching and stocking. Third, it avoids the trouble of merging ponds for overwintering, allowing the fry to be dispersed and intensively reared earlier, promoting early spring growth. 1. Pond renovation. Use the idle winter season to renovate fish ponds: turn small ponds into large ones, stagnant ponds into aerated ones, and shallow ponds
