Abstract
Sequential alterations of
body weights as well as total lipids, triglycerides, cholesterol and ketone body levels in the blood of Protopterusannectens during twelve month duration of
aestivation were investigated.? The
results revealed that after the first trimester of dormancy, there was
significant body weight reduction (p<0.05) coupled with significant hypolipodaemia, hypotriacylgly-cerolaemia
and hypocholesterolaemia respectively (p<0.05)
but without significant ketonaemia
(p<0.05).? The total lipid,
triglyceride, cholesterol and body weight reductions continued through the
second, third and fourth trimesters of aestivation respectively (p<0.05)
but with serum ketone body levels remaining
unaltered (p<0.05).? Thus, the
utilization of lipids as a source of energy during aestivation of P. annectens does not lead to ketone
body accumulation.
