Splenic lipidosis in intensively cultured perch, Perca fluviatilis L.

---

Macroscopically visible lipid deposition varying in size from pinpoint to 8-mm diameter was found in
spleens of a population of intensively farmed perch,Perca fluviatilis L. over a 24-month rearing period.
Large agglomerates of adipocytes distinguishable from surrounding normal tissue occurred in all individuals
with spleen lipidosis. Several affected fish presented total dystrophy of large clusters of hepatocytes.
Prevalence of lipidosis was 5.0% at 12 months and 16.6% at 24 months. There was no significant difference
between fatty acid profiles of liver or perivisceral fat of perch with and without lipidosis except for linoleic,
myristic, c-linoleic, cis-eicosatrienic, palmitooleic acid. Body weight and hepatosomatic, perivisceral fat
and splenosomatic indices were not associated with lipidosis. There was no significant effect of lipidosis
on mortality or growth.

Keywords: dietary fat, histopathology, lipid metabolism,lipoma, nutritional pathology, spleen pathology
