What are the main technical measures for polyculture of fish and soft-shelled turtles?
1. Pond renovation: Build a 30 cm high escape-prevention wall around the pond, with the four corners rounded into arcs, smooth the inner wall with cement, and it is best to have an inverted-L-shaped coping on top of the wall to prevent the old soft-shelled turtles from escaping. Set up bamboo rafts in the fish pond as sunning platforms for the old soft-shelled turtles to bask their backs, and there is no need to add other necessary equipment such as feeding platforms. 2. Reasonable stocking: filter-feeding fish that feed on plankton, omnivorous fish, and herbivorous fish can all be polycultured in the same pond with old soft-shelled turtles, but black carp should not be stocked in fish-turtle polyculture ponds. 3. Reasonable stocking density of old soft-shelled turtles. If the main approach is to use

Symptoms and Prevention and Treatment Methods of White Plastron Disease in Soft-shelled Turtles
White plastron disease is a difficult and complicated turtle disease that has appeared since 1996. It is currently the most harmful turtle disease, with the highest mortality rate and the greatest treatment difficulty. If not treated in time, it can cause all of them to die. At present, there is considerable controversy over the pathogen of this disease. The reported pathogens include: 1) Bacteria: the pathogens are Aeromonas hydrophila, Proteus, and Edwardsiella tarda. 2) Virus: spherical virus with a diameter of 80nm. 3) Cross-infection: death occurs after viral infection is followed by secondary bacterial infection. The author believes that, based on the analysis of the particularly obvious effect of adding vitamins during treatment,

What are the prevention and control methods for soft-shelled turtle red plastron disease?
Cause: Caused by Aeromonas punctata infection. Symptoms: Sick turtles respond slowly to external stimuli. The most obvious sign of the disease is that the entire plastron becomes red and swollen or appears in a red patch pattern, accompanied by ulceration and edema. Some turtles bleed from the mouth and nose. Necropsy shows severe liver lesions; some are black; some are mottled. The intestines show localized or entire-segment congestion and inflammation; some have fluid accumulation in the abdominal cavity. Prevention and control: 1) Control stocking density; 2) Improve the pond bottom substrate, and thoroughly clear the pond at the end of production;

Raising red worms as feed for turtles and soft-shelled turtles delivers high economic returns
In turtle and soft-shelled turtle breeding ponds, small red worms often appear, swimming in clusters and sheets on the pond surface and in the corners, forming a layer of red water bloom on the water surface. The real name of the red worm is Cladocera, and it is a type of zooplankton in water bodies. It is composed of many planktonic flea species, with an average body length of about 1 mm. The normal body color of Cladocera is grayish white; it turns red only when the water is lacking oxygen, which is why red worms are mostly found in foul ditches. When large numbers of red worms are found in a turtle or soft-shelled turtle pond, it indicates that the pond water has begun to deteriorate,

What are some practical methods for protecting fish and soft-shelled turtles from the cold in winter?
1. Pond selection: Choose a deep-water pond (over 2 m deep) that is sheltered from the wind and faces the sun for natural overwintering. The water in the overwintering pond should not remain stagnant for long periods; usually replace part of the pond water every 20 to 30 days, each time replacing 1/4 to 1/5 of the total pond water, to prevent pond water contamination. 2. Set up windbreaks and cold-shelter holes: On the north side of the pond, a 2 m high windbreak can be built from straw or soil, and on the east and west sides, earthen walls sloping toward the south can be built in a dustpan shape to reduce the impact of the north wind, so that when a cold wave strikes, the water temperature will not drop significantly. Around the pond,
