The rhythm of growth and feeding in larva,juvenile and young fish of Paracanthobrama guichenoti were studied under the artificial farming conditions.The results showed that,from 1 to 70 days,the daily growth rates of body length and weight were 3.55% and 11.26%,respectively.Head length/Total length decreased along with the increasing day age.The relationship between the total length （L,mm） and body weight （M,mg） was counted to be M= 0.001 2 L²-0.056 4 L⁺ 0.650 4, between body weigh （M,mg） and day age （D,d） was expressed to be M= 0.004 3 e^{0.093 6 D} ,and between the total length （L,mm） and day age （D,d） was calculated to be L= 0.015 4 D²-0.012 8 D⁺8.196 5. 20 day age late larva have the highest feeding rate with an ample supply of bait, a peak value was observed at 8:00 am. In contrast, 40 day age juvenile showed feeding rhythm obviously and was identified as the type of daytime feeding, daily feeding rate was 2.337 6%. After 6 h to eat gluttonously, the whole alimentary canal of late larva was evacuated completely, while juvenile needed 5 h.Furthermore,under starvation, 10 d larva were dead partially after 3 days,and all died 5 days later. The same tendency was also found in 20 day age larva at 6th and 9th day,40 day juvenile at 7th and 10th day,respectively.
