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.
Scientists have found copepods living in waters around the globe. Theyâre in fresh water and oceans from the surfaces to the depths. Theyâre in frigid polar waters as well as hot springs, rivers, lakes, streams and caves. They also live in the stagnant waters of leaf litters and old tires.
