Detailed Explanation of Key Technical Points for Freshwater Farming of Whiteleg Shrimp (Litopenaeus vannamei)
Abstract The most suitable water temperature for the survival of whiteleg shrimp is 28-32°C. Release them when the weather is clear or in the evening; the most suitable water temperature for releasing fry is 20°C or above. Select high-quality fry with good vitality, quick responses, and a transparent body. Before releasing them into the freshwater

Freshwater Farming Techniques for Whiteleg Shrimp (Litopenaeus vannamei) and Treatment of White Feces Disease
Abstract Pond: mud-sand bottom, water depth about 2 m, inlet filtered with 60-mesh silk gauze. Seedstock: use fully desalinated shrimp fry, turn on the aerator the day before stocking, and release a small number of test shrimp before stocking the fry in large quantities. Feed: fixed times and amounts, fixed spots and quality, small amounts given frequently,

Prevention and Treatment Methods for Several Gill Diseases in Whiteleg Shrimp (Litopenaeus vannamei) Farming
1. Gill disease caused by Vibrio. Diseased shrimp float and swim slowly on the water surface, with gill filaments slightly swollen and dark gray, showing degeneration and necrosis at the tips. Under high magnification, actively motile bacterial cells can be seen. Ponds where this disease occurs have severely polluted bottom sediment and poor water quality, and the disease peak season is from July to September.

Experience Sharing on Lighting Management in Open-Sided Poultry Houses
1. Brooding Period The lighting during the brooding period mainly stimulates the chickens' feed intake, and the effects of lighting on chicks are mainly manifested in two aspects: light duration and light intensity. At this time, problems with light duration are prone to occur. Some farmers, without considering weight gain, provide 8 hours of light during the first 2-3 weeks of brooding.

Artificial breeding techniques for whiteleg shrimp (Litopenaeus vannamei) farming
The whiteleg shrimp (Litopenaeus vannamei) is native to the area around Ecuador in South America. It was first introduced to China from the Americas in 1988, and it is one of the three most heavily farmed shrimp species in the world by production volume known to date. Compared with the Chinese white shrimp, the whiteleg shrimp has a longer breeding season, a shorter larval rearing period,

How to meet the nutritional needs of sows during the breeding period
Feeding and management of open (non-pregnant) sows. The task of open sows. During this period, for various reasons, sows consume a great deal of various nutrients in their bodies, and most are relatively thin and weak. Therefore, nutrition must be strengthened to quickly restore body condition, meeting their needs for protein, energy, vitamins, minerals and

A Detailed Guide to Open-Air Farming Methods for the White Jade Snail
The white jade snail is an edible snail, large in size, with white flesh, tender and delicious meat, high economic value, and quite competitive on the international market. (1) Advantages of open-air artificial farming. First, it has fast growth; open-air farming can meet the snail's requirements for the three key factors of temperature, humidity and feed, so growth and development are fast, and the growth rate is higher than that of box farming. ⟦4 <p>The white jade snail is an edible snail, large in size, with white flesh, tender and delicious meat, high economic value, and quite competitive on the international market.</p><p></p><p>(1) Advantages of open-air artificial farming</p><p>First, it has fast growth; open-air farming can meet the snail's requirements for the three key factors of temperature, humidity and feed, so growth and development are fast, and the growth rate is higher than that of box farming. Second, the meat is white and of good quality. Third, the shell patterns are clear and bright, very suitable for making shell-carving crafts. Fourth, it saves labor and feed, yields more product, and brings higher income.</p><p>(2) Open-air farming conditions</p><p>① White jade snails freeze to death below 5°C, so areas where the average winter temperature is above 5°C can serve as the boundary for open-air farming. Most areas of the middle and lower reaches of the Yangtze River in China can carry out open-air farming.</p><p>② A good sales channel must be found; before farming snails, the sales channel must be secured first, so that the products produced do not stagnate and cause economic losses.</p><p>③ There must be strict measures and equipment to prevent white jade snails from escaping.</p><p>④ The ecological environment of the open-air farming site must be maintained and kept free from damage by humans and other organisms.</p><p>(3) Farming techniques</p><p>① Selection of site. A site sheltered from the wind, shaded, humid, with good drainage, and covered with weeds or shrubs, at the foot of mountains, on slopes, hills, wasteland, or idle land in front of and behind houses, can all be used as stocking sites.</p><p>② Building escape-prevention facilities. (a) Dig a perimeter ditch. Around the farming site, dig a ring of ditch, generally 10 cm wide and 5 cm deep; where conditions allow, shallow water can be stored in the ditch. This perimeter ditch both prevents snails from escaping and serves to drain and store water for the site. (b) Plant scallions, garlic, chives, onions, etc. around the site as a barrier belt; because the above plants can give off a pungent smell, they have a certain repellent effect on snails. (c) Use wire mesh or plastic mesh to make a fence with inward-facing angles, forming a "┐" shape; when the snail climbs to the top, because it is inconvenient to turn and its center of gravity is downward, it will fall back into the farming site. (d) Taking advantage of the snail's physiological reaction of avoiding high alkalinity, build a wall about 1 m high with bricks around the farming site, and coat the inner wall with a layer of highly alkaline lime-sand-cement about 1 cm thick, with a pH value of 11.5; the escape-prevention effect is very good.</p><p>③ Releasing young snails at the right time. Release young snails when the temperature begins to stabilize at 20°C; in the Nanjing area, this is from May 10 to 20. The young snails should be uniform in age, preferably 2-3 months old and 5-10 g in weight, and the stocking density is 100-200 snails per sq m.</p><p>④ Strengthen management. Every night and early morning, especially after rain, is the peak period for white jade snails to come out and move about; timely inspection allows escaped snails to be retrieved in time.</p><p>⑤ Take good measures against the harm of natural enemies such as rats, frogs, snakes, birds, turtles, centipedes and ants.</p><p>⑥ Sell the products in time. Generally in early September, when the snails reach an individual weight of more than 30-50 g, they should be sold promptly to prevent losses caused by changes in disastrous weather.</p>

A Detailed Introduction to Three Methods of Snail Farming
1. Open-air farming method. Farmland can be used for farming. After plowing, break the soil up finely, plant broadleaf trees around the field for shade, and enclose the perimeter with netting to prevent the snails from escaping. A flat-roofed building's roof can also be used for farming: spread a layer of loose soil more than 10 cm thick on the roof, and
