Add butter/olive oil combination. Add the fillets, without crowding. Increase heat to high and saute, shaking the pan from time to time, until the bottom of the fish is nicely browned, about 3 minutes. Turn and brown the other side. Remove fish to a plate and keep warm in the oven. Repeat with remaining fillets.
Copepods are considered to be primary consumers. They form an important link in the food chain. Their diet consists of small plant plankton.
Copepods may be herbivorous, carnivorous, or omnivorous. The diversity in the diets of copepods provides alternative pathways for acquiring nutrients and thus, increases the chances of copepods obtaining a nutritionally complete diet (Kleppel 1993).
