|Confined to the subtropical and temperate waters of China, the Yellow Sea and Sea of Japan north to Vladivostock, former USSR (Collette & Russo, 1980:fig. 3).|
|Habitat and Biology|
|S. niphonius is an epipelagic, neritic species,carrying out a spawning migration in spring (March to June) and a feeding migration in fall (September to November) in the Inland Sea of Japan (Hamada & Iwai, 1967).|
Spawning extends from April to May with medium-sized fish producing some 550 000 to 870 000 eggs (Kishinouye, 1923).
No detailed food studies are available, but the species is known to prey on small fishes.
|Maximum size is 100 cm fork length and approximately 4.5 kg in weight.|
|Interest to Fisheries|
|Japanese Spanish mackerel is taken throughout its range, but is the most important Scomberomorus species in Japan. The world catch reported by China, Japan and the Republic of Korea fluctuated between 42 800 metric tons in 1975 and 68 300 metric tons in 1981 (FA0 1983). Driftnets and set gillnets are the major fishing gears in the seasonal fishery in the Inland Sea of Japan operational from March to June and from September to November.|
The fish are primarily marketed fresh, and are especially tasty in winter.The total catch reported for this species to FAO for 1999 was 595 103 t. The countries with the largest catches were China (565 764 t) and Korea, Republic of (19 502 t).
