| Abstract: | Compartmentation of liver, kidney muscle and gill tissues in relation to glucose-6-phosphatase and fructose 1,6-diphosphatase was examined in the fishes Labeo rohita, Clarias batrachus and Channa punctatus. The anterior region of the right and left lobes of the liver contained the maximum of fructose 1,6-diphosphatase and glucose-6-phosphatase, while the minimum was in the right and left lobes of gill tissue. Herbivore fish had the highest gluconeogenic enzyme content followed by carnivore and piscivore species. The observed enzymatic variations in the three fish species were discussed. |
