Abstract
    Penaeus monodon postlarvae (PL-5) were reared for 10 days on Artemia nauplii enriched with various levels (2.65, 5.30, 12.60, 22.35 and 31.20 mg/g DW) of (n-3) highly unsaturated fatty acids (HUFA). On day 5 and 10, their resistance to osmotic shocks (transfer from 30 ppt to 0, 5, and 10 ppt diluted seawater) was analyzed. After 5 days, postlarvae fed Artemia containing 12.6 mg/g (n-3)HUFA or more had a significantly higher resistance (p<0.05) than controls. Five days later, no significant difference could be detected among the treatments. A positive correlation was found between the stress resistance of PL-10 and the survival recorded five days later in each tank (p<0.02). It is concluded that the resistance to osmotic stress is a valuable quality indicator for penaeid postlarvae. On the other hand, neither growth rate, nor their size can be considered adequate quality criteria.
