Effects of climate change on fish reproduction and early life history stages
Seasonal change in temperature has a profound effect on reproduction in fish. Increasing temperatures cue reproductive development in spring-spawning species, and falling temperatures stimulate reproduction in autumnspawners. Elevated temperatures truncate spring spawning, and delay autumn spawning....

Seasonal change in temperature has a profound effect on reproduction in fish.
