The Impact

Background and Objectives: The study measured the impact of crude oil fractions and its derivatives like kerosene on the early life and sub-adults growth of African catfish, Clarias gariepinus in terms of mild, acute and chronic toxicity effect. It also examines the effect of indiscriminate spillage of crude oil derivatives on aquatic organisms.  Materials and Methods: Blood profiles such as Red Blood Cell count (RBC), White Blood Cell count (WBC), Blood Differentials, Hemoglobin, (HB), and Packed Cell Volume (PCV) of the treated fishes and control were estimated after exposure of the fish to the kerosene pollutant. Behavioral changes in fish exposed to8.0ml/l, 16.0ml/l, 25.0ml/l and 50.0ml/l of kerosene pollutant varied from erratic swimming, moribund movement, jumping and lack of balance. Results: At concentration 8.0ml/L, mean total mortality was observed within 72hours of exposure. The lethal concentration (LC50) was 8.0ml/L and highest mean mortality observed with 80% kerosene pollutant. PCV of the exposed fish was 26% when compared to the control 27%, HB was 8.9 gdl as against 9.0 gdl in the control. Total WBC was 640 x 109/L as against 1280 x 109/L in control. RBC reading was 2.1 compared to 5.3 mm3 of the control.  Lymphocyte was 80%, Neutrophil was 4% and monocyte 16% compared to 62%, 8% and 30% in control respectively. There was decrease in white blood cells counts for 8.0, 16.0, 25.0 and 50.0ml/L groups (p<0.05) compared to the control. Conclusion: The study concludes that it is necessary to ensure the safety of aquatic life forms especially fishes, by minimizing aquatic pollution with kerosene to sustain fish food quality, availability and security.

Background: Natural preservatives are compounds produced by natural ingredients that can suppress bacterial growth and development. Natural preservatives are carried out because most of the preservatives circulating are chemicals and unsafe for the body. One of the natural preservatives is by using garlic extract (Allium sativum L).  Objective: This study is aimed to determine the effectiveness of the antibacterial garlic (Allium sativum L) as a natural preservative in fresh African catfish (Clarias gariepinus).  Method: This research used the Pour Plate iroculation method. African catfish (Clarias gariepinus) which is soaked with garlic (Allium sativum L) with a concentration of 7%, 14% and 21% for 30 minutes, then the fish will be kept at room temperature with a storage period of 24 hours and 48 hours and calculated growth in bacterial numbers with the Colony counter.  Result: Based on the research result, it was found that garlic extract (Allium sativum L) can obstruct the effectiveness of antibacterial in African catfish (Clarias gariepinus) at a concentration of 14%.

<p><em>Effect of four types of diluents</em><em>s</em><em> and four concentration of DMSO (5%, 10%, 15% and 20%) against the motility of African catfish sperm were evaluated after storage at freezing temperatures. </em><em>The steps in preparation the 16 treatments combination of the diluents</em><em> </em><em>are </em><em>preparation of diluents, mixing </em><em>diluents </em><em>with DMSO, packing </em><em>of semen </em><em>in</em><em>to</em><em> 0.3-ml straw, equilibration of </em><em>semen </em><em>at 4 °C for 30 minutes, freezing </em><em>of </em><em>semen in nitrogen vapor liquid </em><em>at </em><em>a height of 6.5 cm for 10 minutes</em><em>,</em><em> and subsequent</em><em>ly</em><em> storage of </em><em>semen </em><em>in liquid nitrogen (-196</em><em> <sup>0</sup></em><em>C) for further analy</em><em>sis</em><em> </em><em>of </em><em>post-thawing motility (PTM). </em><em>The result showed that t</em><em>he highest level of motility of spermatozoa </em><em>was </em><em>in </em><em>treatment </em><em>P</em><em><sub>1</sub></em><em>D</em><em><sub>15 </sub></em><em>(45.7 ± 4.3%) and the lowest </em><em>was </em><em>in </em><em>treatment </em><em>P<sub>2</sub>D<sub>20</sub> (14.5 ± 13.2%).
