Abstract The Gymnodiptychus pachycheilus is a second-class nationally protected wild animal and a vulnerable species with a key role in maintaining fish biodiversity in the upper reaches of the Yellow River. In order to investigate the effects of starter feed on early growth and survival, Artemia, rotifers, and commercial feed were used to feed the larvae of G. pachycheilus for 21 days and recorded growth and survival rate. The results showed that the larvae fed Artemia and rotifers had significantly higher body weight and total length in 0—7 days than those in the larvae fed commercial diet did (P<0.05), thus priority to use biological food is recommended in the 0—7 days. After the 7th day, however, high specific growth rate of 6.79%/d was observed in the larvae in the Artemia group, while the specific growth rate was dropped sharply from 5.83%/d (0—7 days) to 2.12%/d (7—14 days) in the rotifers group, indicating that the suitability of rotifers was shown to be decreased significantly after 7 days. There was survival rate of 90.17% in the Artemia group, significantly higher than that in other groups (P=0.015). It is recommended to adopt a two-step feeding strategy: use of Artemia or rotifers from 0 to 7 days, and after 7 days, switching to feeding Artemia alone, which can not only ensure the growth rate, but also minimize the mortality rate to the maximal extent.
