Very little is known about bonefish spawning or their juvenile stages. As a $141 million-dollar industry in The Bahamas alone, understanding these crucial phases of the bonefish lifecycle is important to ensure the population is kept healthy and the fishery sustainable. In 2016, Dr Travis Van Leuween and the Flats Ecology team at the Cape Eleuthera Institute focused on identifying and understanding bonefish spawning behavior. In partnership with the Bonefish and Tarpon Trust, the team tracked the hormone levels of 43 individual fish using blood samples to create hormone profiles during both spawning and non-spawning time periods. By matching hormone levels to potential spawning events, they can identify hormones which may promote reproductive cues including egg and sperm production.
