DIFFERENT DIETS ON GROWTH AND WSSV-RESISTANCE OF PENAEUS MONODON
不同饵料对斑节对虾(Penaeus monodon)幼虾的生长及对WSSV 敏感性的影响

Five different diets were tested to feed artificially-WSSV (white spot syndrome virus) infected Penaeus monodon in high density, and the body length and body weight before and after 20-day experiment were measured and the survival rate calculated. The result shows that the group fed with Artemia salina nauplii had the best, while that of shrimp flakes the worst, in growth performance among all the groups (P<0.01). The group of shellfish took the second place, and that with shellfish, the third. The fish-feeding group grew faster than the one with artificial feed. By infecting with WSSV on Day 12, an obvious (P<0.05) difference occurred among groups. In addition, the death rate of WSSV-infected group was must higher. The analysis results of semi-quantitive PCR show no WSSV infection before but after the experiment when all showed positive sign of infection.
