Hatching and rearing of carp (Cyprinus carpio L.) in the Polonnaruwa nursery

Carp fingerlings have been raised at Polonnaruwa since 1957 (Ling, 1962), by a method essentially the same as that described by Hora and Pillay (1962). The present work was initiated to assess and increase the efficiency of the nursery. Two experiments were carried out. In the first, 3 females and 6 males were used. Thirty bundles of Hydrilla were tied to the 3 strings and 10 of them taken at random were used for egg counts. In the second experiment the same number of fish was used but 36 bundles of Hydrilla were tied to the 3 strings and 9 of these taken at random for egg counts. The results of these 2 experiments are given in Table l.
