    Sublethal effects of the Water -Soluble Fractions of Virgin Diesel Oil on some Physiological Parameters of Clarias Gariepinus Juveniles.
    (Department of Zoology, Nasarawa State, University Keffi, 2020-03-06) Lemuel, A.S.; Banyigyi, A.H.; Makpo, James Kpuk; Abdulmalik, A.A.; Andrew, N.C.
    This study was undertaken to evaluate the sublethal effects of the water-soluble fractions of virgin diesel oil on some physiological parameters of C. gariepinus juveniles. The mean weight of C.gariepirws Juveniles weight of l.61±1.86g, total length of 9.5± 10.5cm and standard length of 11.0±l2.5cm were exposed to sublethal concentrations of 0.58 ml/L, 0.29 ml/L, 0.14 ml/L, 0.07 ml/L, 0.04 ml/L and control 0.00 ml/L. There were significant differences at (P<0.05) on the different levels of sublethal concentrations.The tissues include.; gills, liver and intestine. The alterations considered include; the gills; inflammation, hyperplasia, fusion, lamella aneurism, epithelial lifting, abrasion and necrosis, in the liver, there was lesions,1 and:inflammation, and also alterations of the intestine were mainly sloughing of the intestinal villi and intestinal rhueosa. It was concluded that contamination of water-soluble fractions of virgin diesel oil in any water body or aquatic environment can induce several histopathological alterations in the tissues of Clarias gariepimisjvivtnWz.

    Sublethal effects of the Water -Soluble Fractions of Virgin Diesel Oil on some Physiological Parameters of Clarias Gariepinus Juveniles.
    (Department of Zoology, Faculty Of Natural And Applied Sciences, Nasarawa State University, Keffi, 2020-06-21) Lemuel, A.S.,; Banyigyi, A.H.; Makpo, James Kpuk; Abdulmalik, A.A,; Andrew, N.C.
    This study was undertaken to evaluate the sublethal effects of the water-soluble fractions of virgin diesel oil on some physiological parameters of C. gariepinus juveniles. The mean weight of C.gariepinus Juveniles weight of 1.6l±1.86g, total length of 9.5±l 0.5cm and standard length of 11.0± 12.5cm were exposed to sublethal concentrations of 0.58 ml/L, 0.29 mi/L, 0.14 ml/L, 0.07 ml/L, 0.04 ml/L and control 0.00 ml/L. There were significant differences at (P<0.05) on the different levels of sublethal concentrations.The tissues include; gills, liver and intestine. The alterations considered include; the gills; inflammation, hyperplasia, fusion, lamella aneurism, epithelial lifting, abrasion and necrosis, in the liver, there was lesions, and inflammation, and also alterations of the intestine were mainly sloughing of the intestinal villi and intestinal mucosa. It was concluded that contamination of water-soluble fractions of virgin diesel oil in any water body or aquatic environment can induce several histopathological alterations in the tissues of Clarias gariepinus juvenile.
