Fishes employ a variety of reproductive strategies for successful propagation of their progeny.
However, endocrine control of reproduction has been investigated in only a limited number of species. Environmental endocrinology in relation to the reproductive cycles of selected marine fishes in their natural habitat is one the areas of my research interests. One of the major problems in aquaculture of most finfish species is the lack of spontaneous spawning in captivity. The absence of appropriate environmental cues for spawning in an enclosed environment leads to the disruption of neuroendocrine pathways that control the surge of gonadotropin required for gamete maturation. A variety of environmental factors, such as day-length and water temperature, influence reproductive cycles in fishes.
