(2017) For
the management of endangered species, a periodic health assessment is
important, as diet in captivity is restricted due to cost and some
nutrients are lost during the processing, storage and thawing of fish.
The objective of this study was to compare and assess the nutritional,
as well as the physiological health of both the captive and
free-ranging Yangtze Finless Porpoises (YFPs) through
biochemical markers, selected electrolytes, enzymes and hematological
parameters. Our results showed statistically significantly (P
< 0.05) higher levels of some biochemical markers (HDL-c/LDL-c,
globulin, TP, Urea, Creatinine and BUN), enzymes (GGT), electrolytes
(K+, Na+, PO43- and Mg2+)
and hematological (WBCs, lymphocytes,
eosinophil) parameters in wild compared to the captive populations.
However, the captive population also showed significantly (P
< 0.05) higher levels of some biochemical markers (LDL-c, albumin
and albumin/globulin), enzymes (AMS), electrolytes (Cl¯) and complete
blood count (neutrophil, monocytes and basophil) parameters versus wild
populations. Differences in the parameters of captive YFPs could be due
to their limited diet of only three fish species as well as their
environment (captivity). Whereas, wild YFPs, continuously feed on a
large variety of live fish species and shrimp as they travel long
distances. Our results suggest that mineral supplements be added to
their diet. As well, improved physical fitness training and hygienic
conditions are required for the effective management of captive finless
porpoises.
