Copper,a common chemical contaminant in aquatic environment,is known to be toxic to aquatic life at high concentrations.Previous studies have demonstrated copper-induced structure damages in gill and
在以40%棉粕为主要蛋白源的基础饲料中,分别在其中添加0.5%蛋氨酸,0.5%、1.0%胆汁酸盐和0.5%、1.0%牛磺酸(记0.5%Met,0.5%Bile、1.0%Bile,0.5%Tau、1.0%Tau)配制了5种等氮等能的试验饲料,以全鱼粉组(64.4%鱼粉,记FM)、低鱼粉组(15%鱼粉,记LFM(Low Fishmeal)为对照,投喂初始体重为(0.26±0.02)g的中华绒螯蟹幼蟹,
本试验以凡纳滨对虾(Litopenaeus vannamei)幼虾(初重为2.96±0.01 g)为研究对象,探究低鱼粉饲料中添加微囊氨基酸和蛋白酶对其生长性能的影响.试验共设计5组等氮等能的饲料:鱼粉含量20%的正对照组、鱼粉含量15%的负对照组(用豆粕等蛋白替代鱼粉)、在负对照饲料中分别添加微囊赖氨酸、蛋氨酸(达到与正对照一致的水平),175mg/kg蛋白酶,微囊赖氨酸、蛋氨酸+175 mg/
The metabolic and immunological responses of the juvenile Australian red claw crayfish to nitrite and the ameliorating effects of chloride were evaluated,and an effective chloride concentration to pre
C-type lectins (CTLs) play important roles in the innate immunity of invertebrates.Although several reports showed that CTLs importantly functions in host-pathogen interactions,limited research has fo
Potato late blight caused by Phytophthora infestans is a heavy disease in potato produc-tion in Yunnan province.
核盘菌(Sclerotinia sclerotiorum(Lib.)de Bary)是一种寄主范围非常广泛的病原真菌,可引起400多种植物病害,造成巨大的经济损失.在病害循环中,适宜条件下菌核萌发形成子囊盘,成熟子囊盘可释放大量子囊孢子,子囊孢子随风散落在寄主植物上萌发并侵染,造成菌核病害的流行.
The amount and distribution of genetic variation in Phytophthora infestans populations is one of the key factors influencing the occurrence and epidemic of potato late blight.
