Ichthyoplankton

Ichthyoplankton (pronounced: ik-thee-o-plank-ton) are the eggs and larvae of fish. They are usually found in the sunlit zone of the water column, less than 200 meters deep, sometimes called the Epipelagic zone. This is the principal spawning ground for many fish species.

Etymology

The term "ichthyoplankton" is derived from two Greek words: "ichthys" which means fish, and "planktos" which means drifter or wanderer. This term is used to describe the fish in their earliest stages of life, where they drift along with the ocean currents.

Epipelagic zone: The topmost layer of the ocean where there is enough sunlight for photosynthesis.
