| morphological re-description and new geographical records for three digenean parasites infecting african sharptooth catfish clarias gariepinus (pisces: clariidae) in egypt. | sixty specimens of african sharptooth catfish clarias gariepinus (clariidae) were collected during the period of march 2014-february 2015 from boat landing sites and fishermen of the river nile at beni suef governorate, egypt, and examined for the presence of digenean parasites. the morphology of these parasites was studied by using light microscopy to describe morphological and morphometrically measurements for different body parts. three digenean species belonging to three different genera wer ... | 2016 | 27481172 |
| pesticide residues in milk and fish samples collected from upper egypt. | in egypt, buffalo milk is much preferred by consumers over cow's milk, while small catfish and bolti fish are common in the diet of farmers. samples of buffalo milk, catfish, and bolti fish collected from beni-suef governorate (upper egypt) were analyzed for organochlorines and polychlorinated biphenyls. the results obtained by gas chromatography and confirmed by thin-layer chromatographic techniques revealed high amounts of organochlorines in milk; residues were lower but occurred more frequent ... | 1988 | 3235406 |
