Japanese anchovy
Small schooling fish of the northwest Pacific
The Japanese anchovy is a small pelagic fish found in the northwest Pacific Ocean. It supports commercial fisheries in Japan, South Korea and China using traditional and modern nets. This short-lived species grows quickly and forms large schools in coastal waters.
- Lives for only two to three years
- Caught using traditional nangjangmang nets in Korea
- Found in the Sea of Japan and Yellow Sea
- Maximum weight reaches forty-five grams
What it is
This species belongs to the anchovy family and lives in large groups. Adults typically measure fourteen centimetres in length. The largest individuals reach eighteen centimetres and weigh up to forty-five grams. Its body shape is streamlined for fast swimming in open water. The fish inhabits the northwest Pacific region. It shares biological traits with the European anchovy, including a similar size range and life cycle.
Where it lives
The distribution covers several major bodies of water in East Asia. Populations thrive in the Sea of Okhotsk and the Sea of Japan. They are also common along the east coast of Japan. The range extends into the Yellow Sea and the East China Sea. These coastal and shelf environments provide the necessary conditions for their survival. The species is not found in tropical or southern hemisphere waters according to available records.
How it lives
These fish form dense schools as a defence mechanism against predators. They live for a short period, usually two to three years. This rapid turnover allows populations to recover quickly if fishing pressure is managed. Their behaviour is typical of pelagic species that stay near the surface. They move with currents and temperature changes in the northwest Pacific. Specific dietary habits are not detailed in the provided information.
Breeding and life cycle
The short lifespan suggests a fast growth rate and early maturity. Like other anchovies, they likely release eggs into the water column.
Fish and people
Commercial fleets target this species in Japan, China and South Korea. In South Jeolla Province, fishermen use a traditional fixed shore net called nangjangmang. This long bag set net captures schools as they move near the coast. The catch serves as food for local populations and export markets. It is a staple in regional cuisines across East Asia. The fishing methods vary from traditional nets to industrial trawling in other areas.
Status and threats
Overfishing can impact short-lived species, but no specific threats are listed here. Management relies on national fisheries regulations in the range countries.
