摘要
实验于１９９６年５月～９月对３种规格养殖中国对虾在不同条件下的耗氧率和排氨率进行了测定。结果表明，温度、体重、盐度和摄食状态对其代谢有显著影响。耗氧率（ＱＯ）和排氨率（ＱＮ）与温度正相关，ｌｎＱＯ＝０．０５８Ｔ－２．８９４；ｌｎＱＮ＝０．０７６Ｔ＋１．１１６；而与体重呈负相关，ＱＯ＝０．５１５Ｗ－０．１２６；ＱＮ＝２５．０５Ｗ－０．１９９。在盐度５～３５范围内，中国对虾（３．０２５ｇ±０．０８８ｇ）的耗氧率和排氨率在盐度２８时最小。中国对虾（３．１３ｇ±０．０７２ｇ）摄食沙蚕和配合饲料，在饱食状态下耗氧率比饥饿状态下分别提高了８３．９％和２９．３％，排泄率增加了１１３．８％和９３．６％，表明摄食时蛋白质代谢增加显著。
The oxygen consumption and ammnia N excretion rates of Penaeus chinensis are studied under different conditions. The results are shown as follows: 1. The oxygen cosnumption rate and ammonia N excretion rate are correlated positively with temperature and negatively with body weight. The correlation with temperature can be expressed by ln Q 0=0.058T-2.894 and ln Q N=0.076T+1.116. The correlation with body weight can be expressed by Q 0=0.515W -0.126 and Q N=25.05W -0.199 . 2. The oxygen cosnumption and ammnia n excretion rates decrease with the increase of salinity in the range of 5￣28, and increases at 35. The minimums appear at salinity 28. 3. The metabolism for feeding polychaete worm is higher than commercial pellet. The oxygen consumption rates are 83.9% and 29.3%, the ammonia N excretion rates are 113.85 and 93.6% for feeding polychaete worm and commercial pellet respectively, higher than those in fasting.
