| Summary: | <b>Aim:</b> "Labidochromis caeruleus" and "Xiphophorus hellerii" are commercially
important aquarium ornamental fish. The aim of this study, upon the discovery
that these species died by showing various clinical signs in optimum conditions
and standard feding conditions, was to investigate the causes of death and to
determine the problems that may be encountered in the field.<p>
<b>Materials and Methods: </b>In our study, five of Labidochromis caeruleus and
Xiphophorus hellerii, which were grown as seven species of ornamental fishes
and died with similar clinical symptoms were used. Because of the changes observed
in the liver, macroscopically, liver dissection, and HxE staining were carried
out respectively and examined by light microscopy.<p>
<b>Results:</b> Serosangioz exudate in the abdomen, anemi, livers yellow-brown, lipidosis
with inflammation, excessive growth, crispandeasily degradable consistency,
bluntends and petechial hemorrhage foci were observed. Microscopically
seen that the hepatocyte cytoplasms were filled by large oil droplets with macro
and micro vesicular. Fatty changes in liver cells are widely distributed from central
veins toward hepatocytes in the middle of the lobule and periportal areas.<p>
<b>Conclusion:</b> The histopathological changes in the liver were investigated and
under optimum conditions and standard feding conditions, and the sensitivities
of these commercially important aquarium ornamental fishes were determined
against market baits. It has been concluded that the sespecies can be a model
organism for studies on fatty liver thanks to widespread/clear visualization of
fatty liver and observation of a case of steatohepatitis, which is an important
health problem and has not been previously reported for Labidochromis caeruleus
and Xiphophorus hellerii species. |
