为了探讨投饵对对虾的影响,作者研究了投喂频率对凡纳滨对虾(Litopenaeus vannamei)生长、消化酶和免疫酶活性以及氮收支的影响。结果表明：投喂频率对凡纳滨对虾的存活率、生长率、饲料系数、氮生长效率以及部分消化免疫酶活力有显著影响。日投喂5次实验组获得较高的存活率、增质量率和特定生长率以及较低的饲料系数。投喂频率与特定生长率间呈二次曲线关系,投喂频率为4.45次时,获得最大特定生长率。摄食氮、生长氮和排泄氮和排粪氮,以日投喂频率2次为最低,5、6次较高。高投喂频率组获得较高的消化酶和免疫酶活性。

Effect of feeding frequency on growth characteristics, digestive enzymes, immune enzyme and nitrogen balance of Litopenaeus vannamei was studied. The results indicated that feeding frequency of Litopenaeus van-namei was significantly effected by survival rate, growth rate, feed coefficient, the nitrogen balance and part of immune enzymes activity. The groups which were fed 5 times per day had higher survival rate, weight increasing rate and specific growth rate, and lower feed coefficient. Conic relationships were found between specific growth rate and feeding frequency. The maximum specific growth rate was obtained when they were fed 4.45 times per day. Feeding nitrogen, growth nitrogen and excretion of nitrogen and fecal nitrogen, reached the lowest when 2 times per day, and higher if 5 and 6 times per day. The high feeding frequency group got higher digestive enzymes and im-mune enzymes activity.
