Sažetak
The livers of twenty-nine species of fish from twenty different fish families obtained from the Adriatic Sea (Croatia) were investigated. In the livers of twenty species of fish hepatopancreas was found, but not always in the same species. Histology and stereological analysis was undertaken of the liver in ten teleost fish, one each of: common pandora, Pagellus erythinus (Linnaeus, 1758) and in whiting, Merlangius merlangus euxinus (Nordmann, 1840). In the liver of the common pandora there was a smallest proportion of liver tissue 85.81% and liver blood vessels 2.50% and the largest proportion of hepatopancreas tissue 14.19% and hepatopancreas and liver blood vessels 2.50% and the largest proportion of hepatopancreas blood vessels 1.70%. The liver of whiting contained the largest proportion of liver tissue 95.14% and liver blood vessels 4.60% and smaller proportion of hepatopancreas tissue 4.86% and hepatopancreas blood vessels 1.43%. A statistically significant correlation was only obtained between the percentages of the mean values of the examined tissues and blood vessels of the livers between whiting and common pandora (P < 0.01), but not between the groups of the same species. In whiting and common pandora the division to the liver lobuli, the Glison trias is not visible and the perisinusoidal space (space of Dissae) is large and well developed. The Glison trias is not visible and the perisinusoidal space (space of Dissae) is large and well developed. The sinusoidal capillaries were narrow and irregularly shaped and the hepatocytes were organized in tubular form.
