Habitat and Ecology
Length of maturity at 50% is 60 cm fork length (FL) for females and 40 cm FL for males in
Maximum size is more than 100 cm FL, 9.4 kg. The all-tackle game fish record is a 9.35 kg fish caught at Shirasaki, Wakayama, Japan in 2007 (IGFA 2011).
There are two migrations in the Inland Sea of Japan, a spawning migration in the spring (March to June) and a feeding migration in the fall (September to November) according to Hamada and Iwai (1967).

Red List Criteria
Two different stock assessments have been conducted in the East China Sea and in the Inland Sea. In the East China Sea, this species is caught by purse seiners, and catch per unit effort (CPUE) since 1994 by Japanese purse seiners is increasing. In the Inland Sea, this species was very depleted in the past as estimated biomass in 1985 was 60,000 tonnes and dropped to 2,000 tonnes in 1998. There is a slight increase to 5,000 tonnes in 2007 based on recovery program that begin in 2002 with a restocking program (Uozumi pers comm 2009). In the western part of Japan, catches are increasing as this species is likely increasing its range because it used to be rare in this region. There are no major fisheries for this species on the eastern part of Japan.
In Taiwan, reported catches of this species to FAO have declined from 15,000 tonnes in 2007 to 1,400 tonnes in 2008, but this needs to be confirmed as catches are reported from distant water long-lines which are not normally used to catch this species (Chang, pers comm 2009).
Relevance to Humans and Ecosystems
Japanese Spanish mackerel
The Japanese Spanish mackerel, Scomberomorus niphonius, also known as the Japanese seerfish, is a species of true mackerel in the scombrid family (Scombridae). Their maximum reported length is 100 cm, and the maximum reported weight is 7.1 kg.
Japanese Spanish mackerel is an important species for fisheries in east Asia. South Korea is the country reporting the biggest annual catches, followed by Japan and Taiwan. These added to a relatively modest total catch of about 56,000 tonnes in 2009. However, China reports very large catches of unidentified seerfish (Scomberomorus spp., fluctuating around 400,000 tonnes in 2000–2009), without reporting catches of any single Scomberomorus species. It is likely that these catches include a significant proportion of Japanese Spanish mackerel.
