Prevention and Control Methods and Technical Key Points for Rotting Stomach Disease in Sea Cucumber Aquaculture
This disease mostly occurs in the late auricularia larval stage, and is more likely to break out during the high-temperature period from June to July each year and when larval rearing density is high. The disease has been found in both Shandong and Liaoning provinces, and its incidence rate has shown a trend of increasing year by year. The main symptoms of disease and death are: the larval stomach wall thickens

Technical Methods for Inducing Estrus in Meat Dog Breeding
The estrous cycle of adult female dogs is irregular. Affected by many factors such as season, environment, feed structure, and physical condition, female dogs generally produce one and a half to two litters per year. Mastering artificial estrus induction techniques can enable most female dogs to produce two to two and a half litters per year, and four to five litters of pups in two years.
