Haematological Responses in Tilapia Guineensis Exposed to Butachlor in the Laboratory

: Tilapia guineensis treated to butachlor in the laboratory had its haematological characteristics evaluated. The fish were exposed to the chemical at five different doses over a period of fifteen days: 0.00 (control), 0.05, 0.10, 0.15, and 0.20 mg/L. Temperature, pH, dissolved oxygen, nitrite, and ammonia were the five water quality parameters assessed during the exposure. After the experiment, fish blood samples were taken, and conventional laboratory techniques were used to evaluate the samples for haematological parameters. The study's conclusions showed that as the chemical's concentration rose, so did the levels for ammonia and nitrite. In contrast, the dissolved oxygen values decreased. Both pH and temperature were within the same range. Moreover, among the most important toxic manifestations are significant decreases (P<0.05) in hemoglobin (Hb), packed cell volume (PCV), red blood cell count (RBC), and platelet concentrations; dose-dependent changes were also noted in mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC). Fish exposed to butachlor in aquatic habitats can have their health quickly assessed by looking at these parameters' change.
