| 摘 要： | Oxygen uptake under starvation and short periods of sudden temperature change was measured forlarval herring (Clupea harengus L.) reared at average temperature of 7.3, 11 and 12.9℃. Larval stagesbetween first feeding and premetamorphosis were used. For comparison, the routine oxygen uptake(ROU) was also investigated and followed the relationship Q=0.974+0. 174 tW~(0.210), where Q is in μg/(mg·h), W is dry body weight in mg and t is temperature in ℃. The oxygen uptake under starvation(SOU, deprived of food for 24 h) was different from the routine when the larval dry weightwas less than 0.6-0.8 mg, it increased with temperature and body weight giving the reationship Q=1.568+0.110 tW~(0.380), if the larval dry weight mp more than 0.6-0.8 mg, it reverted to the norm(Q=1.704+0.078 tW~(-0.349)). The oxygen uptake was tested in short periods (3 h) of sudden temperaturechanges in six groups: 7.3 to 11, 7.3 to 12.9, 11 to 7.3. 11 to 12.9, 12.9 to 7.3 and 1.29 to11℃. The oxygen uptake in the 7.3 to 12.9 and 1
