摘　　要：在实验室测定了不同条件下凡纳滨对虾 (Litopenaeusvannamei)的摄食率、生长率及食物转化率 ,并探讨了体质量和温度等因子的影响。结果表明 ,温度和体质量对凡纳滨对虾的摄食率及生长率有显著的影响 ,温度对食物转化率影响不明显。在温度 1 6～ 3 1℃的范围内 ,摄食率及生长率随温度的升高而增加 ;相同温度下 ,随个体质量的增加摄食率、生长率及食物转化率下降。凡纳滨对虾摄食率 (RF)、生长率 (RG)和食物转化率 (EF)与温度和体质量的复回归关系分别为 :RF=0 .461W- 0 .793e0 .12 2T(r2 =0 .876,P <0 .0 1 ) ,RG =0 .1 63W- 1.398e0 .174T(r2 =0 .784,P <0 .0 1 ) ,EF=0 .3 84W- 0 .54 6 e0 .0 4 6T(r2 =0 .5 2 9,P <0 .0 5 )。The effects of temperature and body weight on ingestion rate,growth rate and food conversion efficiency of Penaeus vannamei were studied in laboratory.The experimental results indicate that ingestion rate and growth rate are correlated positively with water temperature and negatively with the body weight,but there weren’t notable effects on the food conversion efficiency of P.vannamei with water temperature.Relative relationship can be expressed by following multiple regression equations:R F =0.461W -0.793 e 0.122T (r 2 =0.876,P<0.01),R G =0.163W -1.398 e 0.174T (r 2 =0.784,P<0.01),E F =0.384W -0.546 e 0.046T (r 2 =0.529,P<0.05).
