Abstract

During the period 2014-18, a total of 219 cases of fish mortalities were being investigated under a passive surveillance programme. Among different disease incidences parasitic diseases were found to the major contributor accounting for 74.88% cases followed by bacterial diseases of 12.79%, mixed bacterial and parasitic diseases of 10.50% and viral diseases of 1.83%. Among different parasitic cases mixed parasitic infections (37.80%) were found to be premier cause of disease followed by Argulosis (19.51%), Dactylogyrosis (18.90%), Myxosporean infections (12.80%), Trichodinosis and Ichthyophthiriasis (3.04%) and other parasitic infections (4.88%). Among bacterial infections, aeromonads group account for 66.66% diseases besides few emerging pathogens of public health significance. Catla was found to be the most susceptible species and winter season being the most favorable season for occurrence of infectious diseases. Fishes weighing 100-500 g were most vulnerable to disease occurrence. This study generated a comprehensive disease incidence scenario in freshwater aquaculture in eastern India.

2014-2018年印度东部淡水养殖场传染病发病率的被动监测研究

在2014- 2018年期间，根据被动监测计划，共调查了219例鱼类死亡病例。在不同的疾病发病率中，寄生虫病占74.88%，其次是细菌性疾病占12.79%，细菌与寄生虫混合疾病占10.50%，病毒性疾病占1.83%。不同寄生虫感染类型中，以混合寄生虫感染为主(37.80%)，其次为舌虫病(19.51%)、趾虫病(18.90%)、粘孢子虫病(12.80%)、毛癣病和鱼鳞病(3.04%)和其他寄生虫感染(4.88%)。在细菌感染中，除少数具有公共卫生意义的新发病原体外，气单胞菌群占66.66%。发现猫是最易感的物种，冬季是传染病发生的最有利季节。体重100-500 g的鱼最容易发病。这项研究生成了印度东部淡水水产养殖中疾病发病率的综合情景。
