The early evolution of fish is unclear. It is thought that they evolved in the Cambrian Period (542 - 488 Ma). A primitive fish called Haikouichthys which is commonly recognised as one of the 1st fish to evolve lived around 530 million years ago.

∙ 8y agoFish, like all species, are always evolving. Most of these tiny adaptations will be failures that do not add to the species' survival rate (meaning they fail to survive long enough to breed and cannot pass on the adaptation to their offspring). But if you are asking when did fish first appear, the first fish appeared in the Cambrian Period about 510 million years ago.
