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.

The remaining 0.3% was made up of snails, fingernail clams, water mites, sculpin eggs and fish. [4] Thus the mottled sculpin is not a major threat to game fish though it has been found to eat trout eggs. [4] [11] Sculpin are cannibalistic. Males are known to eat their young if one contracts some kind of virus or fungus. The males also eat small ...
