Typical predators for Daphnia are the phantom midge larvae Chaoborus, the heteropteran Notonecta sp. or small fishes26,27,28. In the presence of fish predators, Daphnia react with an earlier sexual maturity, an increased fecundity and the production of resting eggs26,29,30.
Are water fleas harmful to humans?
Why they are harmful. Spiny waterfleas are not harmful to humans or pets, do not carry disease, and do not affect lake water quality for swimming. However, their presence can be harmful to our ecosystems. Spiny water fleas affect our fish populations by threatening their food source.
