Abstract
In this study the influence of various water origin on physical, chemical and heavy metals levels of El-Abbassa fish farms, El-Sharqia governorate, Egypt during experiment period for five months from March till July 2018 were investigated. The first fish pond was irrigated from Ismailia Canal, which branched out from River Nile, while the second was supplied by agriculture drainage water. Physical, chemical and heavy metals levels of different water resources in different two fish ponds were monthly determined, also gonadosomatic index of the ovary of Nile tilapia was monthly determined. In addition, protein, cholesterol, carbohydrates and glycogen were determined at the end of experiment period. The results showed that, physical, chemical and heavy metal levels of different water resources in two fish ponds of El-Abbassa fish farms were differed significantly but not exceed the maximum permissible limits reported by ECS, 1994 and USEPA, 2006 so, quality analysis of ponds water, fish species and fish feeds during the breeding season must be performed continuously, accurately according to national and international standard specifications to ensure the success of the breeding process and to obtain the higher fish production, furthermore, the levels of pollutants must be continuously monitored in this important fish farms to improve the quality of the cultured fish species.
