Japanese Mackerel Fish: The World’s Most Popular Fish The Japanese mackerel fish is immensely popular in the United States and worldwide.

Origin of the Japanese Mackerel Fish

The Japanese mackerel fish is scientifically called “Scomber japonicus.” It is native to the waters of Southeast Asia, specifically the Philippines, China, Taiwan, and Japan.

Both the Asian mackerel (Scomber scombrus) and the American mackerel (Scomber scombrus) are members of the same family. Both are also referred to as “mackerel” when they live in other countries, though they are not mackerels.

Japanese Mackerel Fish Breeding

The Japanese mackerel fish is a hermaphrodite, meaning that it has both male and female sex organs.

The female’s eggs are laid in the water, and the male’s sperm. Once in contact with each other, they have a chance to breed and make baby mackerels.

Japanese Mackerel Fish Diet

The Japanese mackerel fish can grow up to two feet long. It feeds mainly on other fish, though it will also eat different types of marine life, such as crustaceans and squid.

The Japanese mackerel fish is believed to migrate all over the waters it lives in during the breeding season, though no one is exactly sure where they go or how long they stay.

It is known that they travel from north Okinawa to south Okinawa and back again during this time frame.

The Japanese mackerel fish’s mating season is quite brief. It only lasts a few weeks and begins in November or December, ending in January or February.

The male will try to find the female by swimming up to two feet above her and reaching out into its fins with his trunk.

He will then clasp the belly of the female with his mouth hooked onto its fin and swim back down to the bottom of the river, making an unmistakable “clicking” sound with his fin each time he does so.
