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.
