Prevention and Control Methods and Technical Key Points for the "Huaban" Disease in Sea Cucumber Aquaculture
This disease is also called "sliding board disease", "board-shedding disease" and "disintegration disease". It mostly occurs when barrel-shaped larvae metamorphose into five-tentacle larvae and in juvenile sea cucumbers after the larvae attach to boards. It is one of the most serious and commonly occurring epidemic diseases in the late stage of sea cucumber (Apostichopus japonicus) seedling rearing. The disease is highly contagious and develops quickly

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
