文摘

C. striata larvae fed live prey 1 ×/d showed poorest growth and stress resistance. Growth improved as the same ration was allocated from 2 ×/d to 4 ×/d in smaller meals. Stress resistance and Na+/K+ ATPase activity were higher in larvae fed 2 ×/d to 4 ×/d. Feeding frequency of live prey did not affect larval survival or fatty acid profiles. Judicious feeding of live prey resources maximizes larval growth and vitality.
