Analysis of annual data on fish landing showed that Oreochromis niloticus and Cyprinus
carpio have invaded the lower stretch of the Yamuna river at Allahabad in a big way. The
estimated annual catch was dominated by O. niloticus (147.81 kg day-1) followed by C.
carpio (132.04 kg day-1) and miscellaneous group (92.34 kg day-1) and they accounted for
24.36%, 21.76% and 15.22%, respectively. In case of Indian major carps, Cirrhinus mrigala …

Study was undertaken during the period August 2011 to July 2012 from the Yamuna river. Analysis of annual data on fish landing showed that Oreochromis niloticus and Cyprinus carpio have invaded the lower stretch of the Yamuna river at Allahabad in a big way. The estimated annual catch was dominated by O. niloticus (147.81 kg day-1) followed by C. carpio (132.04 kg day-1) and miscellaneous group (92.34 kg day-1) and they accounted for 24.36%, 21.76% and
15.22%, respectively. In case of Indian major carps, Cirrhinus mrigala shared maximum with a contribution of 38.10 kg day-1 (6.28%). Catla catla and Labeo rohita shared 12.69 kg day-1and 20.45 kg day-1, respectively. For conservation point of view C. carpio var. communis and O. niloticus species should be monitored in the Yamuna river. Both species are very harmful for fish biodiversity in the Yamuna river.
