Comprehensive Prevention and Control Techniques for Soft-Shelled Turtle Gill Gland Inflammation
Since the intensification of soft-shelled turtle farming, because research on turtle diseases has lagged behind production, various hidden disease risks have remained latent. Among them, the most harmful and also the most difficult to treat, turtle gill gland inflammation, has gradually become prevalent in recent years. At the farm where the author works, the annual losses caused by this disease account for about 50% of total losses. This disease repeatedly occurs in broodstock turtles and adult turtles, and has now developed to affect the entire production process. 1 Main symptoms and pathogens This disease is mainly characterized by systemic edema and pale plastron. Most have intact body surfaces

A Detailed Guide to the Main Diseases of Soft-Shelled Turtles and Their Prevention and Treatment
With the continuous development of the soft-shelled turtle farming industry, the ever-increasing density of artificial breeding, and the promotion of constant-temperature intensive farming, the factors causing turtle diseases are increasing day by day, bringing many difficulties and economic losses to specialized farming households. Below is an introduction to the causes and prevention and treatment techniques of several common diseases of soft-shelled turtles. 1. Hemorrhagic disease: Caused by viruses and Aeromonas punctata. Bleeding points or bleeding spots can be seen on the plastron of diseased turtles, and erosive growths appear on the carapace; in severe cases it can cause death. Prevention and treatment: Apply furazolidone at 1.5 g/cubic meter to the whole

What are the prevention and treatment methods for ornamental turtle trauma
[Cause] During capture and rearing, the turtle's shell, skin, limbs, mouth and other parts may suffer abrasions, injuries or crush wounds. [Symptoms] Local redness and swelling, tissue necrosis, and pus. [Prevention and treatment methods] For fresh wounds, bleeding should first be stopped by applying pressure with gauze; in severe cases, apply Yunnan Baiyao, then clean the wound surface, and wash with disinfectant drugs (93% hydrogen peroxide, 0.5% potassium permanganate) to prevent infection. Large wounds should be sutured and bandaged. For old, suppurating wounds, first enlarge the opening, remove the pus and necrotic material from within the wound

How to prevent and treat Epistylis infestations in soft-shelled turtles
Cause: Caused by parasitism of Epistylis spp. (bell animalcules) of the genus Epistylis. Symptoms: On the body surface of the soft-shelled turtle, clusters of flocculent material can be seen with the naked eye on the limbs, back and neck, and even the head, yellowish or earthy yellow in color; in water it is not as soft and flowing as water mold, but somewhat stiff and wing-like. When the condition is severe, the limbs turn brown or copper-green. A small number of parasites has no effect on the soft-shelled turtle, but heavy parasitism affects its movement, feeding, and even breathing, causing the turtle to waste away and die. Prevention and treatment: 1) When the disease occurs, use 0.5 ppm "Fish-use

Chinese Box Turtle (Yellow-margined Box Turtle) Breeding Methods and Key Points of Daily Feeding Management
The yellow-margined box turtle (Cistoclemmys flavomarginata), also known as the broken-plate turtle, snake-eating turtle, clamp-plate turtle, and yellow-plate turtle. Its taxonomic position is the family Geoemydidae, genus Cuora, species Cistoclemmys flavomarginata. Within China it is distributed in Anhui, Henan, Macao, China, Hong Kong, China, Taiwan, China, Fujian, Hunan, Jiangsu, Zhejiang, Guangdong, Guangxi, and elsewhere. Outside China it is distributed in Japan. [Morphological characteristics] The head is smooth, the front of the snout is flat, and the upper beak has a distinct hook-like curve. The top of the head is olive-colored, with a yellow "U"-shaped arc stripe behind the eyes. The carapace is dark reddish-brown and rather

Detailed Introduction to the Classification and Common Varieties of Softshell Turtles
Introduction to the Classification and Common Varieties of Softshell Turtles With the improvement of people's living standards and the growth of market demand at home and abroad, softshell turtles have gradually moved from hotels, restaurants and eateries into ordinary households. As a nutritious food, softshell turtles' dietary therapy and medicinal therapy functions can meet the needs of consumers at different levels. Market demand has stimulated production, and China's softshell turtle farming industry has developed rapidly, with the scale of farming continuously expanding and output increasing accordingly. Large-scale farming urgently needs a large number of softshell turtle hatchlings. Due to the rapid development, the breeding of seedlings, the classification, distribution and basic biological research of softshell turtles, as well as hatchling cultivation, species identification and disease prevention in farming production, cannot adapt to the needs of production development. Aquaculture operators and merchants in our province have purchased many softshell turtle hatchlings through different channels from abroad, Taiwan, China and other provinces in the mainland. Because these hatchlings come from different sources, their seed stock quality is unclear and it is hard to tell the genuine from the fake. Some farmers and aquaculture operators have paid a lot of "tuition fees," causing losses of varying degrees to production. Therefore, studying the classification and common varieties of softshell turtles and breeding superior softshell turtle varieties with good germplasm are urgent issues that must be solved for the sustainable development of the softshell turtle farming industry.

Prevention and Treatment Methods and Technical Key Points for Abscess Disease in Turtles
Turtles in nature are relatively disease-resistant and are also long-lived animals. Common turtles can live for decades, and some can live for one to two hundred years. When turtles are kept in captivity, factors such as deteriorating water quality or insufficient nutrition can easily lead to invasion by various pathogens and cause abscess disease. In recent years, with the promotion of artificial turtle farming, abscess disease has also become prevalent, and in some places the incidence rate has been rising year by year. In the early stage of the disease, a pus-filled swelling appears locally under the turtle's skin, and afterward the pus-filled swelling gradually hardens and forms a raised tumor-like mass. It can be moved when touched by hand, but the inside is hard.

Detailed Explanation of Key Points for Polyculture Techniques of Soft-Shelled Turtles, Crabs, Shrimp and Fish
1. Pond conditions: The pond area is 3.5 mu, the pond bottom is flat, the silt is about 15 cm thick, and the water depth is 1.5 m. A 40 cm wide glass fence is installed around the pond, equipped with one 1.5 kW paddlewheel aerator. 2. Pond clearing and water fertilizing: After clearing the pond by the dry method with 75 kg of quicklime per mu, expose it to the sun for 5 days. One week before releasing the seedlings, fill with water to a depth of 80 cm, and use Feishuibao and EM original liquid to fertilize the water quality, so that the water transparency is about 30 cm and the water color is tea-brown or yellow-green. 3.

How to Prevent Sand-Shelled and Soft-Shelled Eggs in Three-Lined Box Turtles
Three-lined box turtles mate and fertilize in March-April each year, and lay and incubate eggs from May to July. A single sexually mature female turtle lays 3-9 eggs per year; the three-lined box turtle has a relatively low egg production among turtles. Improper feeding and management or the influence of other factors can also cause some three-lined box turtles to lay 1-2 eggs, or even a whole clutch, of sand-shelled eggs (with a sandy, non-smooth shell surface) or soft-shelled eggs, affecting the hatch rate and causing certain economic losses to three-lined box turtle farming. 1 Causes of three-lined box turtles laying sand-shelled or soft-shelled eggs a) Lack of eggshell-producing

What to Do When Alligator Snapping Turtles Kill Each Other? Five Methods to Help You Prevent It Effectively
Alligator snapping turtles are native to North America and Central America. They are physically strong and highly aggressive, making them a relatively unique species among turtles. Alligator snapping turtles are famous for their high reproduction rate, fast growth, large meat yield, and delicious meat, and are now favored by many farmers. They have been promoted for breeding in many regions, with considerable economic benefits. However, in high-density artificial breeding, due to their nature as well as environmental, feed, and mating factors, alligator snapping turtles kill each other, resulting in a low survival rate. To solve this problem, Zhejiang Province
