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

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

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

Detailed Explanation of Soft-Packaging Quick-Freezing Fresh-Keeping Technology for Oyster Mushrooms
Oyster mushrooms have a tender and crisp texture, making them inconvenient to transport and store. Especially during high-temperature periods and peak harvest seasons, if the processing capacity at the place of origin cannot keep up, exporting becomes difficult, and the problem of "difficulty in selling mushrooms" often arises. Therefore, the problems of oyster mushroom sales, transportation, storage, and processing should be fundamentally solved. There are three main traditional methods for storing oyster mushrooms: First, processing them into salted mushrooms for export and domestic sale. However, from the perspective of domestic sales, due to the high salt content, they need to be soaked repeatedly many times before consumption, which is not only time-consuming and laborious, but they still taste too salty when eaten, and the flavor deteriorates, making it difficult for consumers to

What to Do When Oyster Mushrooms Get Soft Rot Disease? Detailed Prevention and Control Methods
Symptom manifestation is mainly shown by the white mycelium of oyster mushrooms growing in a spider-web-like pattern on the surface of the bed, rapidly spreading, covering the bed surface, and surrounding the fruiting bodies. Once the base of the fruiting body is surrounded by mycelium, it becomes infected; the pathogen spreads upward along the stipe, and finally the fruiting body stops growing, its color becomes dull, and it rapidly softens, turns yellow, turns brown, and then rots. Prevention and control methods: First, strictly treat the mushroom shed. Before the mushroom shed is put into use, spray it with Mushroom Disease Eliminator King, keep it sealed for two days, then spread lime powder on the ground at 250 grams per sq m. Second, during the spawn-running period

How to prevent and control soft rot in oyster mushrooms? These methods are very practical
Dong Yushan from Ligou Town, Pingyin County, Shandong Province, wrote in: "The oyster mushrooms grown in my town and the surrounding townships develop small yellowish-brown spots during the fruiting stage, especially when the fruiting bodies are about 1 cm in diameter, which then rapidly expand, and finally the entire fruiting body turns brown, becomes soft and sticky, and ultimately rots. Even though the mycelium inside the mushroom log is still very dense and white, it is very difficult to get another flush. What disease is this? How should it be prevented and controlled? Host Yangguang replies as follows: The situation reported by this friend also occurs quite often in other areas. Judging from the described symptoms,

Prevention and Treatment of Haemogregarinosis in Freshwater Soft-Shelled Turtles and Turtles
Haemogregarinosis is a disease caused by parasitic Haemogregarina. Haemogregarina is a sporozoan belonging to the order Eucoccidiida and the family Haemogregarinidae. Haemogregarina parasitizes the blood cells, liver cells and Kupffer cells of soft-shelled turtles and turtles and reproduces there. (1) Pathogen: Haemogregarina. According to Chai Jianyun et al. (1990), 6 species of Haemogregarina have been found in the bodies of soft-shelled turtles and turtles in China. Taking Haemogregarina sinensis as an example, in the Chinese soft-shelled turtle, there are 3 stages: (1) The mature tissue schizont in the Kupffer cells of the liver is oval

Methods for the Prevention and Control of Common Soft-Shelled Turtle Diseases and Key Technical Points
Soft-shelled turtle diseases can be divided into three major categories: infectious diseases caused by bacteria, molds or viruses, parasitic diseases caused by parasites, and diseases caused by other factors. Among them, the more harmful and common ones are red plastron disease, white plastron disease, red neck disease, skin rot disease, perforation disease, white spot disease, bell-shaped ciliate disease, etc. Below is an introduction to the pathogens, causes and treatment methods of various diseases. 1. Red neck disease. Pathogen. The pathogen of red neck disease is Aeromonas hydrophila, Gram-negative. Carrier turtles and contaminated pond water are the main sources of infection,
