Project Overview

This project evaluated the therapeutic and ameliorative potential of dietary Vitamin C (L-ascorbic acid) in counteracting sub-lethal zinc sulfate ($\text{ZnSO}_4$) toxicity in juvenile Nile Tilapia (Oreochromis niloticus).

Key Methodologies & Outcomes

  • Biochemical Profiling: Evaluated serum enzymes, total protein, and antioxidant defenses (SOD, CAT, and TAC).
  • Tissue Histopathology: Conducted renal and muscle microtomy to analyze cellular lesions and tissue recovery.
  • Toxicity Alleviation: Confirmed that therapeutic supplementation significantly reduces heavy-metal bioaccumulation and accelerates organ healing.
