中华绒螯蟹幼蟹高密度养殖技术及“牛奶病”防控技术要点

High Density Breeding Technology of Chinese Mitten Crab and Key Points of Prevention and Control of"Milk Disease"

中华绒螯蟹是重要的淡水养殖甲壳类动物,由于具有特殊的气味深受消费者的喜爱。近年来集约化养殖为满足还时常需求对生态环境造成严重损害,由于高密度养殖不合理出现许多疾病导致成活率低造成较大经济损失。牛奶病是中华绒螯蟹幼蟹养殖中发生的危害性较大的流行病,病蟹体消瘦组织严重乳化,乳白液体镜检中发现大量酵母菌样微生物,纯化液中含有大量聚团菌体细胞结构清晰。需要研究中华绒螯蟹幼蟹高密度科学养殖技术,加强牛奶病的防控,保证养殖经济效益。概述中华绒螯蟹高密度养殖技术,分析中华绒螯蟹幼蟹牛奶病原因,探讨中华绒螯蟹幼蟹牛奶病防控技术要点。

Chinese mitten crab is an important freshwater crustacean,which is loved by consumers because of its special smell.In recent years,in order to meet the needs of intensive breeding often causes serious damage to the ecological environ⁃ment.Due to the unreasonable diseases in high-density breeding,the low survival rate causes great economic losses.Milk dis⁃ease is a harmful epidemic in the breeding of Chinese mitten crab.The thin tissue is seriously emulsified.A large number of yeast-like microorganisms are found in the milky liquid microscopic examination,and the purification solution contains a large number of aggregate bacteria with clear cell structure.It is necessary to study the high-density scientific breeding technology of Chinese mitten crab,strengthen the prevention and control of milk disease,and ensure the economic benefits of breeding.Summarize the high density breeding technology of Chinese mitten crab,analyze the causes of milk disease,and explore the key points of prevention and control of milk disease.
