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

Overwintering management techniques for freshwater pomfret fry and fingerlings after being stocked into ponds
1. Overwintering pond preparation: area 600-1500 sq m, pond depth 1.5 m; the pond water in the Pukou District area of Nanjing is geothermal spring water, flowing into the pond in a slight current; the inlet pipe is 10 cm, and the mud at the pond bottom is 10 cm thick. After drying the pond and disinfecting it, fill with water. Each pond is equipped with two 3-kilowatt aerators. 2. Pomfret fry and fingerlings
