This item is printed on demand - it takes 3-4 days longer - Neuware -Cyprinus carpio was introduced into India during 1939 and 1957 for aquaculture purpose and it contributes more than 7.17% in total inland fish production. C. carpio was contributed maximum in the Yamuna river compared to Ganga river in landing scenario. Present investigation indicated that the growth rate was higher in the Yamuna river as compared to the Ganga river at Allahabad. The first two years growths were recorded 20.69 cm and 8.36 cm in the Yamuna river and 19.03 cm and 7.46 cm in the Ganga river, respectively. 0+ to 13+ age group fishes were recorded in the Yamuna while 0+ to 11+ age group fishes found in the Ganga. 0+ to 2+ age group fishes were highly exploited in the Yamuna (50.51%) in compared to the Ganga river (45.52%). The sex ratio of C. carpio var. communis was very close to expected sex ratio (1:1) in the Ganga and Yamuna rivers. At last it may be concluded that the C. carpio is a powerful invader in the Ganga and Yamuna rivers at Allahabad, India. 192 pp. Englisch.…

Paperback. Etat : new. Paperback. Cyprinus carpio a ete introduit en Inde entre 1939 et 1957 a des fins aquacoles et represente plus de 7,17 % de la production totale de poissons d'eau douce. C. carpio a contribue davantage dans la riviere Yamuna que dans le Gange en termes de debarquements. La presente etude a montre que le taux de croissance etait plus eleve dans la Yamuna que dans le Gange a Allahabad. Au cours des deux premieres annees, la croissance enregistree etait respectivement de 20,69 cm et 8,36 cm dans la Yamuna et de 19,03 cm et 7,46 cm dans le Gange. Des poissons ages de 0+ a 13+ ont ete enregistres dans la Yamuna, tandis que des poissons ages de 0+ a 11+ ont ete trouves dans le Gange. Les poissons ages de 0+ a 2+ ont ete fortement exploites dans la Yamuna (50,51 %) par rapport au Gange (45,52 %). Le rapport de sexe de C. carpio var. communis etait tres proche du rapport de sexe attendu (1:1) dans les fleuves Gange et Yamuna. En conclusion, on peut affirmer que C. carpio est un puissant envahisseur dans les fleuves Gange et Yamuna a Allahabad, en Inde. This item is printed on demand.

Taschenbuch. Etat : Neu. This item is printed on demand - Print on Demand Titel. Neuware -Cyprinus carpio se introdujo en la India entre 1939 y 1957 con fines acuícolas y contribuye con más del 7,17 % a la producción total de pescado continental. C. carpio contribuyó al máximo en el río Yamuna en comparación con el río Ganges en el escenario de desembarque. La presente investigación indicó que la tasa de crecimiento fue mayor en el río Yamuna en comparación con el río Ganges en Allahabad. Los dos primeros años de crecimiento se registraron en 20,69 cm y 8,36 cm en el río Yamuna y en 19,03 cm y 7,46 cm en el río Ganges, respectivamente. En el Yamuna se registraron peces de entre 0 y 13 años, mientras que en el Ganges se encontraron peces de entre 0 y 11 años. Los peces de entre 0 y 2 años fueron muy explotados en el Yamuna (50,51 %) en comparación con el río Ganges (45,52 %). La proporción de sexos de C. carpio var. communis fue muy similar a la proporción esperada (1:1) en los ríos Ganges y Yamuna. Por último, se puede concluir que C. carpio es un invasor poderoso en los ríos Ganges y Yamuna en Allahabad, India.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 200 pp. Spanisch.…
