fish larvae have several sensory systems that are functional at or soon after hatching and then are developed further during larval and juvenile stages. this study was conducted to investigate development of the eye in rutilus kutum , based on histological and allometric growth analysis during early developmental stages up to 35 day post hatching with emphasis on retinal morphology. for this pu...

the proteins in fish, as well as other aquatic animals has nowadays become an important and complete protein sources in many people’s diets around the world and as a results, there has been a growing interest to protect and ensure the health of this important food source. heavy metals due to their specific physical and chemical characteristics as well as their effects on various ecosystems are ...

The heavy metals concentrations including Zinc, Copper, Lead and Cadmium (Zn, Cu, Pb and Cd) in water and sediments in Gorgan Bay and their accumulation in Rutilus frisii kutum, Acipenser persicus, Rutilus rutilus caspicus and Cyprinus carpio organs (gills, muscle, kidney and liver) were investigated. There was substantial increase in concentration of heavy m...

in this study, levels of cadmium, lead, arsenic and mercury heavy metals, which are required by the who and the unfao to be determined in sea food, were evaluated using flame atomic absorption spectroscopy technique, in tissues of two commonly consumed fish in iran namely rutilus frisii kutum and cyprinus carpio collected from the south coastline of the caspian sea. the average concentration of...
