Abstract: | The results of four field experiments on rearing fry to fingerlings of mainly exotic carp, Hypophthalmichthys molitrix, Ctenopharyngodon idella and Cyprinus carpio var. communis conducted for three- and six-month periods during 1971–1975 are presented. In one experiment Labeo rohita, an indigenous species was also introduced as a compatible species. Fry were stocked at densities of 200 000 and 250 000 per hectare in the three-month period and at 100 000 and 250 000 per hectare in the six-month period.Under pond fertilization and supplementary feeding a high percentage of fingerling survival was recorded; the aggregate percentages ranging between 71.50 and 91.16 in the three-month period and 61.26 and 89.03 in the six-month period. |
