A recent study published in Ecology and Evolution offers a new approach to traditional mark and recapture studies while providing valuable insight into the growth and movement patterns of invasive lionfish. Lad Akins, Dr. James Morris, and Dr. Stephanie Green teamed up to develop a novel way of visually tagging fish underwater, minimizing both tagging time and fish trauma.
Information on fish movement and growth is primarily obtained through the marking and tracking of individuals with external tags, which are usually affixed to anesthetized individuals at the surface. However, the quantity and quality of data obtained by this method is often limited by small sample sizes owing to the time associated with the tagging process, high rates of tagging-related mortality, and displacement of tagged individuals from the initial capture location.
