White crappies in the larval and juvenile stages of life eat zooplankton and continue to feed primarily on small invertebrates during their first year of life. [ 8 ] [ 15 ] [ 16 ] When white crappies reach a length of 12–15 centimetres (4.7–5.9 in), they are considered adult.
Fish larvae are part of the zooplankton that eat smaller plankton, while fish eggs carry their own food supply. Both eggs and larvae are themselves eaten by larger animals. [2] [3] 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).
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.
For example, lake-dwelling Yellowstone rocky mountain cutthroat eat zooplankton and bottom-dwelling insects, [48] while Bear River species in Bear Lake have evolved with a diet largely dependent on smaller fish, such as the endemic Bonneville cisco. [49] Stream-resident cutthroat are primarily drift feeders, eating insects carried by the ...

[3] Gambusia typically eat zooplankton, beetles , mayflies , caddisflies , mites , and other invertebrates ; mosquito larvae make up only a small portion of their diet.
