tag-and-release studies

Tag-and-release studies are a scientific method used to track and understand the movement, growth, and survival of wildlife, such as fish or marine animals. Researchers catch animals, note identifying features or attach tags (like small tags or electronic devices), and then release them back into their environment. By later recapturing or re-sighting tagged animals, scientists gather data on how far they travel, how long they live, or their behavior. This information helps inform conservation efforts, manage populations, and study ecosystem health without harming the animals.
