Some young sticklebacks in freshwater lakes are eaten by dragonfly larvae. Since lateral plates are made of bone, low-plated sticklebacks need to make less bone tissue than their completely plated peers. This allows the low-plated fish to grow more quickly in fresh water, which has a low concentration of minerals.As the threespine stickleback is small, abundant, and a slow swimmer, it serves as a suitable prey for a wide variety of species. Natural predators include fish in the families Percidae, Esocidae, and Salmonidae, as well as avian piscivores such as loons, herons, and kingfishers.As nymphs they feed on aquatic insects, fish, tadpoles, and mosquito larvae. As adults, they eat other flying insects, including mosquitoes and biting flies.
