Abstract:According to the symptoms of the bacterial, viral, parasitic, as well as other non-biological diseases in the main species of abalone in China, we summarized 18 kinds of common abalone diseases and established a reference table for their diagnosis. This retrieval table is composed of specific symptoms in sick abalone observed under visualor 10×10~40 microscopy. The parallel taxonomic retrieval table was drawn, based on the characteristics of different disease. With some pictures also presented for reference, this diagnosis table is established specially for quick and easy retrieval during abalone culture.
