The present study has shown that fish meal protein in feed for striped
catfish (P. hypophthalmus) fingerlings can be replaced by protein from
locally available plant and animal feed ingredients without compromising
growth performance, feed utilisation or carcass traits. However, the
degree of replacement will depend on the properties of the individual
feed ingredient. In order to get acceptance in the industry for these
findings, and to implement new feeding practices in striped catfish
farms, the economical benefits have to be shown and high-lighted. Thus,
studies should be performed on grow-out fish to confirm the present
findings and to quantify the impact on fish performance and product
quality traits, and on the production economy.
