title: [Optimal feeding strategy for juvenile Hucho taimen].
abstract: Three experiments including starvation and re-feeding, starvation and re-feeding recovery, and feeding frequency per day were conducted to approach the optimal feeding strategy for the growth and survival of juvenile Hucho taimen. In the experiment of starvation and re-feeding, all groups of restricted feeding showed non-compensatory growth. However, in the experiment of starvation and re-feeding recovery, different degrees of compensatory growth appeared in different starving groups, among which, the half a day starvation and half a day feeding group (S1/2) had a weight increment approximately the same as the control, and showed completely compensatory growth, indicating that the S1/2 could be a useful feeding strategy for the juvenile H. taimen at its early growth stage with the body mass from 0 to 2 g and at the water temperature from 9 to 15.3 degrees C. In feeding frequency experiment, the group T3 (three meals per day) had the highest body length, body mass, specific growth rate, and relatively high food conversion ratio, indicating that three meals a day could be more effective for improving the growth performance of juvenile H. taimen at its late stage with the body mass from 2 to 21 g and at the water temperature from 8.8 to 15.5 degrees C.
