闽东海域刺激隐核虫的生活史观察及乙酸杀虫效果
Observation on the Life History of Cryptocaryon irritans in Eastern Sea of Fujian and Research on Antiparasitic Effect of Acetic Acid
摘要
Abstract
Cryptocaryon irritan.s ,a holotrichous marine ciliate protozoan that causing "white spot disease" ,is one of the most devastating parasites of marine fish in Fujian Province. In the present study, a strain of C. irritans-like parasite was isolated from Pseudosciaena crocea aquiculture areas in eastern Fujian province and then identified. The morphological features and biochemical characteristics of the parasites were identical to those C. irritans strains which had been reported in other places,this fact suggested that the sampled pathogen was C. irritans. In addition, the acute toxicity of acetic acid to juvenile P. crocea and C. irritans was studied. The results showed that C. irritans theronts were more sensitive to acetic acid than tomonts. Meanwhile,the susceptibility of acetic acid to juvenile P. crocea was an important factor which was considered in the process of killing C. irritans. The results indicated that dealt "white spot disease" infected P. crocea with 157. 4 mg/L acetic acid for 2 h could kill C. irritans theronts effectively as well as unharmful to the hosts,it was a safe drug-using strategy for preventing and curing "white spot disease".关键词
