a-e Histological pictures of the liver of Labeo rohita fingerlings fed different diets. a Liver of Labeo rohita fingerlings fed with 20% protein for seven days either on 26⁰C or 32⁰C showing no visible changes (H & E, 160X). b Liver of Labeo rohita fingerlings fed with 30% protein for seven days on 32⁰C showing mild swollen cells i.e. increase in the size of hepatocyte (H & E, 160X). c Liver of Labeo rohita fingerlings fed with 40% or 45% protein for seven days on 26⁰C, cells are highly swollen (H & E, 160X). d Liver of Labeo rohita fingerlings fed with 40% protein for seven days on 32⁰C showing comparatively higher swollen cells than fed with 30% protein at same temperature (H & E, 160X). e Liver of Labeo rohita fingerlings fed with 45% protein for seven days on 32.⁰C showing sclerosis of the artery i.e. thickening of the wall of blood vessels (H & E, 160X)
