摘要
近年来,河蟹池塘养殖发展较快,由于养殖规模和放养密度的不断扩大,从而造成池水过肥,水质恶化,有机物含量过高,导致河蟹纤毛虫病呈多发趋势。纤毛虫是河蟹养殖过程中常发生的一种寄生虫病,该病死亡率极高,在河蟹的各个生育期均可造成危害。根据近几年来的工作实践经验,在此记述了纤毛虫病的发病症状,分析发病原因,并提出了综合防治技术的一些措施,以期为各养殖生产者防止此病提供参考。
In recent years,for the rapid development of crab pond culture,stocking size and density of the culture continue to expand,resulting in water over fertilization,deterioration of water quality,too high organic content,resulting in multiple trends of disease crab ciliates.Ciliates is a parasitic disease which often occurs during crab culture,the disease has extremely high mortality rate and can cause harm in various crab growth stages.According to recent years working experience,the author gave an account of ciliate disease symptoms,analyzed causes of morbidity and put forward a number of integrated control measures to prevent the disease which provided information for the aquaculture producers.
