在水温 ( 1 6± 1 )℃条件下 ,红鳍东方 (Takifugurubripes)仔鱼孵出后 4d开始摄食 ,此时其卵黄囊体积由初孵时的 0 636mm3减少到 0 375mm3;1 2d时 ,卵黄完全耗尽。最高初次摄食率出现在卵黄耗尽时 ,可达 1 0 0 % ;仔鱼能维持 9d高达 90 %以上的初次摄食率。初次摄食强度最大值也出现在 1 2d。饥饿不可逆点 (PNR)出现在 1 5～ 1 6d。在内营养期日平均增长率为 0 2 1 7mm/d ;在PNR前的摄食期 ,饥饿仔鱼的日平均生长率为 0 0 1 7mm/d ;而摄食仔鱼的日平均生长率为 0 0 95mm/d ;PNR后至死亡前 ,饥饿仔鱼呈负增长 ,而摄食仔鱼的日平均生长率达 0 41 0mm/d。
At the water temperature of (1 6 ± 1) ℃, the larvae of Takifuguurubripes started feeding 4 days after hatching, and the volume of the yolk sac decreased from 0 636mm3 to 0 375mm3 at the beginning of hatch. At 12 days, Completely exhausted. The highest initial feeding rate was 100% when the yolk was depleted. The larvae could maintain an initial feeding rate of 90% for 9 days. The maximum value of initial feeding intensity also appeared in 12 days. The hunger point of irreversibility (PNR) occurred between 15 and 16 days. The average daily growth rate during in-nutrition period was 0 2 1 7mm / d. The average daily growth rate of hungry larvae was 0 0 1 7mm / d during the pre-PNR feeding period while the average daily growth rate of feeding larvae was 0 0 95mm / d. The starvation larvae showed a negative growth before PNR, while the daily average growth rate of larvae was 0 41 0mm / d.
