Question

What do you call it when adult fish of the same species come together in a group and release gametes into the water at the same time?

Answer 1

spawning

Nearly all fish reproduce sexually and have separate sexes. Fertilization is generally external, and most fish are oviparous. Many adults of the same species may come together in a group and release gametes into the water at the same time, which is called spawning. Fish hatch into larvae that are different from the adult form of the species.
