| Abstract | ||
| Twenty water samples were collected from El-Dakhlah City in the New valley governorate, five from fishpond. Metal analyses were carried out in Animal Health Research Institute, Dokki, Giza, Egypt. A total of 200 unsexed 8 months Tilapia fish were used in this study. Fifty fish were collected randomly from each pond and then weighed. The results of this study showed that lead, cadmium, and iron were higher than permissible limits of WHO, on the other hand Iodine, copper and zinc were lower than permissible limits of WHO. Manganese was higher than permissible limits mostly in all examined ponds. The concentration of heavy metals and trace elements in fish tissue showed that Lead, cadmium, iron, zinc, copper, and iodine were lower than permissible limits while Manganese was higher than permissible limits. The average body weight gain of Tilapia fish was high in the filtered water ponds than other ponds. | ||
