Technical Points and Farming Methods for Raising Soft-Shelled Turtles in Rice Paddies
Raising soft-shelled turtles in rice paddies is a form of ecological aquaculture. The rice paddy environment suits the growth of soft-shelled turtles, and the temperature at which rice grows is also the suitable growth temperature for soft-shelled turtles. Rice paddies contain abundant natural feed for the turtles to eat, and during high temperatures the rice can also provide shade for them. The activity of the soft-shelled turtles

Rice field eel cage culture techniques, suitable for both ponds and ditches
The rice field eel is rich in nutrients, has delicious meat, and has nourishing and health-promoting effects, and is deeply loved by consumers. Raising rice field eels requires little investment, has a short cycle, produces quick results, and brings high economic returns, making it a very good rural side business. Using existing fish ponds and ditches for cage culture of rice field eels does not

Five key points for farming freshwater crayfish in rice paddies after the start of winter
We all know that many creatures generally have the habit of hibernating in winter, just like us humans: in winter their activity level drops a lot, so people's resistance is also much weaker in winter, and in winter the crayfish's activity level likewise drops a lot.

Detailed Explanation of Ecological Breeding Techniques for Rice Field Eel Farming
1. Ripening and spawning induction of parent eels: After late May, when the water temperature reaches 25°C, each parent eel is first injected with LRH-A (luteinizing hormone-releasing hormone) 12.5 micrograms, injection volume 0.5 milliliters, to ripen the gonads; 7 days later, inject DOM (domperidone) 0.5 micrograms, injection volume 0.5 milliliters, or LRH-

Efficient Technical Methods for Breeding Toads in Rice Paddies
The toad is a highly valuable amphibian and reptile used for both food and medicine. The toad skin (chan yi) that it naturally sheds and the milky secretion (chan su) collected and processed from its post-auricular glands are precious traditional Chinese medicinal materials. With the depletion of wild resources, artificial breeding is imperative. Using rice paddies to raise toads offers complementary advantages and can form

Environmental Requirements and Management Techniques for Hatching in Rice Field Eel Aquaculture
The hatching rate of fertilized rice field eel eggs is affected by various environmental factors, among which the main ones are water temperature, dissolved oxygen and harmful organisms. (1) Water temperature The embryonic development of rice field eel is extremely closely related to water temperature. This is mainly shown in three aspects: first, embryonic development must be carried out at a suitable water temperature; too high or too low will cause a decline in hatching rate or embryonic deformity. Studies show that the suitable water temperature for embryonic development of rice field eel is 21-28°C, and the optimal water temperature is 24-26°C; second, within the suitable water temperature range, too large or too rapid a water temperature difference can also cause embryonic deformity or death, and it is usually required that the temperature change within a short time should not exceed 3°C, and preferably not exceed 1°C; third, the length of embryonic development time of rice field eel is directly affected by water temperature. At a water temperature of about 30°C (28-36°C), embryonic development takes 5-7 days, and at a water temperature of about 25°C, embryonic development takes 9-11 days.

Preventing Oxygen Depletion in Rice Field Eel Farming in Late Autumn
1. Cooling and aeration. In late autumn the water temperature is still high, which can cause oxygen depletion in the water body. A frame can be set up over the eel pond and covered with straw for shade, or vines such as pumpkin and cucumber can be planted around the pond and allowed to climb onto the frame over the pond for shade, so as to lower the water temperature. 2. Water addition for aeration. Every
