Many benthic copepods eat organic detritus or the bacteria that grow in it, and their mouth parts are adapted for scraping and biting. Herbivorous copepods, particularly those in rich, cold seas, store up energy from their food as oil droplets while they feed in the spring and summer on plankton blooms. These droplets may take up over half of ...
Sea lice (singular: sea louse) are copepods (small crustaceans) of the family Caligidae within the order Siphonostomatoida. They are marine ectoparasites (external parasites) that feed on the mucus, epidermal tissue, and blood of host fish. The roughly 559 species in 37 genera include around 162 Lepeophtheirus and 268 Caligus species.
Calanus finmarchicus is considered to be a large copepod, being typically 2–4 millimetres (0.08–0.16 in) long. [citation needed] Copepods like C. finmarchicus represent a major part of dry weight (biomass) mesozooplankton in pelagic ecosystems. [4] Calanus finmarchicus is high in protein and polyunsaturated omega-3 fatty acids. [5]
The organisms it eats are at a lower trophic level, and the organisms that eat it are at a higher trophic level. Forage fish occupy middle levels in the food web, serving as a dominant prey to higher level fish, seabirds and mammals. [28] Predator fish; Ground fish; Other marine vertebrates
The copepod is a product, reared in huge hundred litre tanks, fed with nearby-cultured micro algae and the nauplii would be constantly filtered out, leaving the adults and copepodites (teenagers) inside the mass culture vessels. These naulpii would be introduced to the larval rearing tanks where the larvae preferentially eat the nauplii. [18]
Calanus helgolandicus is a planktonic herbivore, [8] although it has been shown to eat both dead diatoms and faeces from other members of its species. This copepod seems to select particles based on their structure; marine snow (which is unstructured), is rejected, whereas dead diatoms and objects such as polystyrene (when given as beads 30 micrometers in diameter) are accepted as food.

Calanoida is an order of copepods, a group of arthropods commonly found as zooplankton. The order includes around 46 families with about 1800 species of both marine and freshwater copepods between them. [2]
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.
