Fishes play a vital role in food and nutrition all over the world. Diseases in fishes occur due to interaction of pathogens and stressful environment. Histology and histopathological studies in Catla catla liver reflect the overall health of entire population in ecosystem. Histopathological biomarker in Catla catla liver is based on experimental data to support the infection induced changes in liver tissue and protein content. This research aims to observe the effect of infection on liver. Liver is a major site of many biotransformation reactions, it play major role in digestion of food, energy metabolism, storage and synthesis of proteins. It can therefore concluded that histopathological alterations: liver necrosis, oedema, damage to pancreatic cells, degeneration of hepatocytes, bile duct hyperplasia, parasitic cyst and degeneration, in present study are indicators of poor fish health deteriorating the metabolic activity there by affecting protein content in liver.
