Abstract:
Effects of four kinds of feed and delayed feeding on the survival rate and feeding rate of
Pelteobagrus fulvidraco were studied to reveal the growth characteristics of
Pelteobagrus fulvidraco.The results showed that the best diet of larva
Pelteobagrus fulvidraco was plankton,which could promote the growth of
P.fulvidraco significantly,while the larval body length was 14.174 mm,the survival rate was 84.36% after feeding for 22 d.Delayed feeding could exceed no more than 4 d,and it was suitable to feed a few plankton at 3 d after hatching.It could feed with full bait after 4 d,while the larval feeding rate could reach 100%.In these ways could ensure the survival rate and feeding rate of larvae,reduce the waste of bait,save the cost,and protect the environment.
