Fish larvae are part of the zooplankton that eat smaller plankton, while fish eggs carry their food supply. Both eggs and larvae are themselves eaten by larger animals. [39] [40] Fish can produce high numbers of eggs which are often released into the open water column. Fish eggs typically have a diameter of about 1 millimetre (0.039 in).
Forage fish, also called prey fish or bait fish, are small pelagic fish that feed on planktons (i.e. planktivores) and other small aquatic organisms (e.g. krill). They are in turn preyed upon by various predators including larger fish, seabirds and marine mammals , this making them keystone species in their aquatic ecosystems .

Both plankton play a huge role in keeping our ocean ecosystem healthy. Most zooplankton sink towards the bottom of the ocean during the day, and at night they migrate towards the surface and feed ...

Plankton can be divided into producers and consumers. The producers are the phytoplankton (Greek phyton = plant) and the consumers, who eat the phytoplankton, are the zooplankton (Greek zoon = animal). Jellyfish are slow swimmers, and most species form part of the plankton. Traditionally, jellyfish have been viewed as trophic dead ends.
Many varieties of fish, particularly cold-water oily fish like salmon, are rich in omega-3 fatty acids, “healthy” fats that support heart, brain and eye health.
A planktivore is an aquatic organism that feeds on planktonic food, including zooplankton and phytoplankton. [1] [2] Planktivorous organisms encompass a range of some of the planet's smallest to largest multicellular animals in both the present day and in the past billion years; basking sharks and copepods are just two examples of giant and microscopic organisms that feed upon plankton.
