Abstract Fish processing and preservation is mainly concerned
with improving the quality and value of
seafood and one of the most reliable methods for
maintaining the quality of fish is to keep them alive
till consumption. This guarantees freshness and
more consumer demand unlike the other processed
commodities. However the stress associated with
the live fish handling and transportation is a major
challenge and minimizing this can successfully
improve the survival rate and associated biochemical
quality changes of the fish. Anaesthetics are
known for reducing stress and related problems
during live fish transportation. Hence, a study was
carried out to understand the efficacy of anaesthetics
viz., MS 222, AQUI-S and clove essential oil on the
survival of common tilapia (Oreochromis mossambicus).
Results indicated that these sedatives had differential
effect on live tilapia, with distinctly diverse
induction and recovery time as well rate of survival.
Among the three anaesthetics used, highest dosage
was required for MS 222, moderate levels for AQUIS
and lowest for essential oil for the same extent of
sedation in live tilapia. However more intense
studies are required to understand the dosage levels
for long term transportation. Similarly toxicological
studies on the use of essential oil are to be intensely
explored to standardize their permissible concentrations
in food fishes. Further, trials on the individual
and combined effect of low temperature and
aeration conditions on the survival rate of live
tilapia proved, temperature and aeration to play a
significant role in influencing the survival of tilapia.
