Fish Reproduction

Reproduction in fishes, like other vertebrate animals, involves several physiological processes including development of the male and female organs; growth, maturation, and release of the egg and sperm; and development of mating behaviors.

These processes are regulated internally by hormones produced in the brain, pituitary gland, and gonad. Environmental factors such as photoperiod and water temperature can influence the seasonal timing of reproduction.

The reproductive biology of many commercially-important wild fish, including new target species for aquaculture, are poorly understood. In nature, as well as captivity, environmental conditions can cause dysfunction of the reproductive system.

Our research in the Environmental Physiology Program aims to:
