Stocking of eggs versus hatchlings in rice fields: a comparison of survival and growth of common carp (Cyprinus carpio) fingerlings

The study assesses the relative profitability of stocking eggs versus hatchlings of common carp (Cyprinus carpio) in the rice-fish systems in Bangladesh. Results showed that although stocking eggs-covered water hyacinths directly into rice fields is a simple low cost option, the yields and profits are much higher from incubating eggs in cloth hapas and nursing hatchlings before stocking them into rice fields.
