PIT tags are a game-changer for tracking fish populations, offering an effective and humane solution for researchers. These passive integrated transponder (PIT) tags store essential data, enabling long-term studies on fish behavior, movement, and survival rates. Whether used in rivers, lakes, or oceans, PIT tags provide critical insights into fish migration, helping conservationists and researchers manage aquatic ecosystems more sustainably. Their precision and longevity make PIT tags an essential tool for any serious marine life research or fishery management project.
