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>

Key Technical Points for the Rearing and Management of Tibetan Mastiff Puppies
In order to carry out scientific rearing and management of Tibetan Mastiffs, appropriate rearing and management should be applied at different biological stages. A small Tibetan Mastiff from birth to weaning is called a puppy mastiff. Correct rearing and management at this stage is extremely important; it is the key period determining whether the puppy mastiff is strong and healthy and improving the survival rate of Tibetan Mastiff puppies.

Key Technical Points for High-Yield and High-Quality Freshwater Shrimp (Macrobrachium nipponense) Aquaculture
(1) Monoculture of freshwater shrimp in ponds. 1. Pond conditions: area of 5-10 mu, water depth of 0.8-1.5 m, firm and leak-proof pond embankments, slope of 1:(2-3), flat pond bottom slightly inclined toward the drainage outlet, and silt not exceeding 20 cm. 2. Preparation before stocking: ① Chemical pond clearing: 7-10 days before stocking, fill with 20 cm of water, apply 100-125 kg of quicklime per mu after slaking, and splash evenly over the entire pond for clearing and disinfection to remove wild fish and harmful organisms; ② Aquatic plant planting: species include Hydrilla verticillata, Potamogeton maackianus, etc., with the planting area accounting for 30-50% of the pond area, then fill with water and fertilize. 3. Water quality management: ① Use microbial preparations: such as EM bacteria, photosynthetic bacteria, etc. From late August to early November, use biological bacteria once every 15 days depending on the medication situation to improve the pond water environment. ② Microporous aeration: equip one 3 kW microporous aeration pump for every 20 mu, lay main pipes parallel to the two long sides of each pond, and install 6 disc-type microporous pipe discs with a diameter of 1.5 m per mu of pond. Dissolved oxygen should be above 5 mg/L. When dissolved oxygen in the shrimp pond falls below 5 mg/L, turn on the aeration pump. Aeration time is generally from 12:00 to 16:00 in the afternoon and from 24:00 at night to 6:00 the next morning, and should be extended on rainy or muggy days. 4. Feeding management: mainly feed complete compound feed for freshwater shrimp of different specifications at different stages, supplemented with rice bran and other feed in the early stage. Feed twice a day, with 1/3 in the morning and 2/3 in the afternoon. Adhere to the "four observations" (observe the season, observe the weather, observe the water color, observe feeding activity) and the "four fixeds" (fixed time, fixed location, fixed quality, fixed quantity). The daily feeding amount is 3-7% of shrimp body weight, and the specific feeding amount should be consumed within 2-3 hours. The feed coefficient for the whole season is 1.5-1.8. (2) Mixed culture of shrimp and crabs in ponds. There is no limit to the pond area, but generally no more than 50 mu is appropriate, with a water depth of 1.0-1.5 m. Pond clearing, disinfection, and grass planting are carried out according to the operating procedures for river crab culture. Stock 5-8 silver carp and bighead carp per mu, put in 200-250 kg of live snails per mu, and plant aquatic plants mainly including Hydrilla verticillata, Potamogeton maackianus, Elodea nuttallii, etc., with the aquatic plant coverage controlled at about 60%. During the growth period of young shrimp in autumn, apply fertilizer appropriately and feed a small amount of powdered feed. When using insecticides and disinfectants, avoid both the peak molting period of river crabs and the peak molting period of freshwater shrimp.</p>
