The effects of supplementing formulated feeds with feeding stimulants (four amino acids plus 5'-UMP) on the feeding activity and growth of young eel Anguilla japonica ere studied by means of two-choice preference tests and by separate feeding tests with the unflavoured feed and the flavoured feed.
Elver showed a marked prference for the flavoured feed over the unflavoured feed. While increasing the rearing temperature from 27°C to 28°C resulted in lowered feeding activity of young eel, the flavoured dietary group maintained a relatively high weight gain and feed efficiency at 28°C. Also, the weight gain and feed efficiency of th eflavoured dietay group reared at 24°C were significantly higher than those of the control groups at 24°C or 27°C. Groups of young el fed on the flavoured feed for 40 days showed a preference for the flavoured feed when given simultaneous access to flavoured and unflavoured feeds.
The results obtained are of some relevance to the development of palatable feed for elver and of saving energy in the warm culture of eel.
