Fish are dioecious animals. Almost all of them have external fertilization. Females have a saccular ovary. Males have testes filled with liquid – milk. Fish spawn eggs. Some fish have developed offspring care. In this case, less caviar is spawned. Fish have viviparity (the yolk sac grows to the female genital tract, individuals hatch with spawning) and ovoviviparity (in this case, internal fertilization occurs. Typical for sharks, rays, guppies).
