Changing pattern of fish landings and fish species composition in the Ganga River system.


The River Ganga and Yamuna are main capture Fishery resources in Allahabad region. Fish landings in Allahabad region were observed during January 1998 to Dec. 1998. Average annual landing was recorded 199.3 tonnes. Indigenous major carps rohu, bhakur, mrigal contributed 5.2, 6.2 and 3.5 tonnes respectively. Among the major Carps the catch was dominated by Calbasu and average annual landing was recorded 29.6 tonnes. Trash fish also dominated the catch. If it is compared with present situation, the catch of Indian major Carps have become negligible. Catch is dominated by exotic fishes and certain cat fishes. Hilsa is not seen in the riverine catches.
