摘要
水产养殖是世界上增长最快的部门之一。目前,全球鱼类消费的50%由水产养殖提供。在印度,主要的养殖鱼类是鲇鱼、罗希塔鱼、马尾鱼、毛利鱼、鱼咽鱼和鲤鱼。其中,罗氏乳杆菌是一种被广泛食用的鱼类。本研究旨在研究最广泛使用的除草剂之一草甘膦对L. rohita胚胎发育的影响。草甘膦对罗氏乳杆菌胚胎的96 h LC50为20.89 mgL−1。胚胎在1/10、1/5、1/3 LC50浓度下孵育96 h。观察到的畸形包括腹部弯曲、尾部扭结形成、卵黄囊水肿、心包水肿、鱼鳔不正常扁平。此外,我们观察到96 h时色素沉着减少,24、48、72、96 h时心率下降,所有这些畸形都导致胚胎死亡。本研究表明,草甘膦除草剂对印度主要鲤鱼L. rohita的自然种群有不利影响。
Effects of Sublethal Concentrations of the Herbicide, Glyphosate, on Embryonic Development of the Indian Major Carp, Labeo rohita
Aquaculture is one of the fastest growing sectors worldwide. Currently, 50% of global fish consumption is provided by aquaculture. In India, the major cultivated fishes are Labeo catla, Labeo rohita, Cirrhinus mrigala, Hypophthalmichthys molitrix, Ctenopharyngodon idella, and Cyprinus carpio. Among these, L. rohita is a widely consumed fish. We aimed to study the effect of one of the most widely used herbicides, glyphosate, on the embryonic development of L. rohita. The 96 h LC50 of glyphosate for L. rohita embryos was found to be 20.89 mgL−1. The embryos were exposed to 1/10th, 1/5th,, and 1/3rd concentrations of LC50 for 96 h. The observed deformities included abdominal curvature, kink formation in the tail, yolk sac edema, pericardial edema, and improperly flattened swim bladder. Besides, we could observe a reduction in pigmentation at 96 h and a decrease in heart rate at 24, 48, 72, and 96 h. All these deformities led to the mortality of embryos. This study indicated that the herbicide (glyphosate) can adversely affect the natural population of the Indian major carp, L. rohita.
