Biochemical Impact of Copper Toxicity on Pangasianodon hypophthalmus Fry
Table of Contents
Introduction
An introduction to the topic “Biochemical Impact of Copper Toxicity” Heavy metal contamination, particularly from copper, poses a significant threat to aquatic ecosystems.
Among freshwater species, Pangasianodon hypophthalmus — a commonly cultured edible fish — is particularly sensitive during its fry stage.
This blog post examines how copper exposure disrupts the biochemical balance in these fry, focusing on carbohydrates, proteins, lipids, and overall energy metabolism.
Understanding these effects is crucial for aquaculture specialists, environmental toxicologists, and students studying fish physiology.
The research reveals how even sublethal concentrations of copper can trigger measurable and potentially harmful changes at the molecular level.
This insight is especially important for managing water quality and ensuring the health of fish populations in both wild and cultured environments.
