Effect of climate change on endocrine regulation of fish reproduction

Climate change is a serious concern for aquatic environment which alters physical and chemical properties of the water causing negative impacts on the aquatic organisms including fish. Temperature alteration, ocean acidification, and hypoxia are the major factors associated with climate change, which affects the endocrine regulation of fish reproduction profoundly. Fish being poikilothermic animals, the change in environmental temperature directly affects their body temperature. Seasonal change in temperature has either fastened the spawning process or delayed the process depending upon the species and their spawning window. Ocean acidification and hypoxia had caused threat to larval survival by impairing larval behavior and sensory capacity. Often climate change shows extreme effect of the demography of fishes by leading to a non-spawning season in some species. Depending upon species, geographic location, and spawning ground, exogenous factors possess significant threat on fish reproduction. The present chapter will provide baseline information on effect of different factors of climate change such as temperature, ocean acidification, and hypoxia on fish reproduction and early ontogenesis phase of fish.
