Abstract

Sparidentex hasta is benefitcailt and economical fish in Persian Gulf that has attracted more attention during this years and is a good candidate for marine aquaculture in coastal zone of Iran. It is understood that the optimal ratio of diet ingredients guarantee appropriate growth rates, condition and health of the fish. After adaptation in 2 weeks by a lipid-free diet, fish were fed for 8 weeks by experimental diets in 300 L tanks (n=36). The routine procedures of preparation of tissues were  followed and the paraffin blocks were cut at 5 microns , stained with H&E and studied under light microscope. In some unsuitable ratio, histopathological changes for example congestion, margination of nucleous and vaculation in hepatocyte were seen. Results showed for culture of Sparidentex hasta, with protein(47.7%) and energy(18.95%) was optimized for other liver histological parameters.
