Research during the last decade demonstrates that a number of fish
species use released hormones as sex pheromones that have potent
effects on both reproductive physiology and behavior. Hormonal
pheromones of fish appear to be among the best characterized
vertebrate sex pheromones, and offer exciting possibilities for both
basic and applied research. This paper briefly reviews the current
literature on the identities and functions of proposed fish hormonal
pheromones, and suggests areas in which additional research will
both increase our understanding of these reproductive chemosignals,
and facilitate application of this information to problems associated
with the controlled repr.oduction of cuJtured species.

courtship and spawning behaviors, exerting either releaser effects (rapid
