Caranx koheru Hector, 1875 |
The koheru (Decapterus koheru) is a type of ray-finned fish. It belongs to the Decapterus group, which is part of the family called Carangidae (also known as jacks or trevallies).
This fish is found only in New Zealand. You can find it from Three Kings Island down to the southern part of the North Island.
Where Koheru Live
Koheru are fish that swim in large groups, called schools. They live in the open ocean near the coast. You can find them in shallow bays, harbours, and estuaries. They also like areas near rocky reefs and islands that are offshore. They can live in water from about 2 meters (6.5 feet) deep down to 90 meters (295 feet) deep.
Young koheru prefer rocky areas close to the shore. As they get older, adult koheru form big schools and swim further out at sea.
Koheru Size and Growth
The koheru can grow up to about 40.3 centimeters (15.9 inches) long. They can live for around 10 years. Young koheru grow very quickly. By the time they are three years old, they can already be about 37 centimeters (14.6 inches) long.
What Koheru Eat
Koheru mainly eat tiny sea creatures called zooplankton. Zooplankton are like microscopic animals that float in the ocean.
Koheru and People
People don't usually catch koheru for large commercial fishing businesses. However, many people enjoy catching them for fun as a recreational activity.
