The Effects of n-3HUFA on the Osmotic Stress Resistance
of Postlarval Fenneropenaeus indicus
Abstract
This study was conducted to determine the resistance of Fenneropenaeus indicus to osmotic stress.
PL-l of Fenneropenaeus indicus were reared for 15 days on Artemia urmiana nauplii enriched with
various levels of n-3HUFA. On days lOan 15, their resistance to somotic stress, transfer from 33 ppt
to 0 and 6 ppt, for 30 and 60 minutes were analyzed. In PL-IO and PL-15, Postlarvae fed with
Artemia containing 33/8 mg/g DW n-3 HUFA and DHNEPA ratio of 2/5, had a significantly higher
resistance in 80% and 100% reduced salinity (P
correlation observed between DHNEPA ratio in Artemia and osmotic stress resistance (Oppt) in PLIO
(r=0.99, P<0.05) and PL-15 (r=0.96, P
found between the osmotic stress resistance of PL-I 0 in 6 and 0 ppt for 30 minutes as well as the
survival recorded in five days later in each tank (r=0.87, P<0.05; r=0.85, P<0.05). It is concluded that
resistance to osmotic to osmotic stress is a rapid, inexpensive and valuable quality indicator for
postlarval penaeidae shrimp .
