摘要: 研究了密度(361.20、722.40和1083.60尾/m2)和碳水化合物水平(15.47、29.15和41.00%)对凡纳滨对虾存活和生长的影响。5周的饲养结果表明:在三个密度水平,随碳水化合物水平的升高,对虾存活率和特定生长率均呈下降趋势,而饲料系数呈上升趋势;在三个碳水化合物水平,随密度的升高,对虾存活率、特定生长率、摄食量和饲料系数均呈下降趋势

Abstract: A 3×3 factorial experiment was conducted to determine the effects of density (361.20、722.40 and 1083.60 individuals/m2) and dietary carbohydrate levels (15.47%, 29.15% and 41.00%) on survival and growth of juvenile L. vannamei. The experiment lasted for 5 weeks. The results showed that at each density level, the survival rate and specific growth rate decreased while food coefficient increased with increasing dietary carbohydrate level; at each dietary carbohydrate level, the survival rate, specific growth rate, food consumption and food coefficient decreased with increasing density level.
