Skipjack tuna

Bonito actually has two peak seasons. The first is in spring, from April to May, and the second is in summer, from August to September. In particular, bonito caught in early summer is rich and fatty, making it delicious as sashimi or tataki. The first bonito landed that year is called “hatsugatsuo,” while the bonito that migrates south around autumn is called “modorigatsuo.”

flying fish

Tobikko, tobiko, and tobiran are flying fish roe. They are small with a popping texture and a bright orange color. They are often used as toppings for sushi and salads. By the way, salmon roe is called ikura, and cod roe is tarako.

I don’t have a stomach.

Carp, sardines, Pacific saury, and medaka are called “agastric fish,” meaning they do not have a stomach. Goldfish and flying fish are also classified as agastric. In these fish, the esophagus connects directly to the intestines, and digestion reportedly takes about 30 minutes. Because food is digested so quickly, they can keep eating continuously for 24 hours.

Because it looks similar to a sword

The cutlassfish is a distinctive species with bulging eyes and sharp teeth. Its name is said to come from its resemblance to a katana, hence “tachi-uo” (literally, “sword fish”). Another theory holds that the name derives from its habit of swimming vertically while ambushing prey above its head.

pectoral fin

When a flying fish takes to the air, the part that functions like wings is its pectoral fins. Flying fish spread their pectoral fins wide and can glide over the sea surface. This helps them escape predators and travel long distances.

mackerel

Mackerel is rich in omega-3 fatty acids. These omega-3 fatty acids are believed to be effective in preventing arteriosclerosis. Omega-3s are expected to improve blood cholesterol levels and help keep the blood flowing smoothly.

archerfish

The archerfish, about 30 centimeters in length, true to its name, shoots water from its mouth like a gun to knock down insects and other prey above the water’s surface. Archerfish have a highly developed ability to aim at their prey and can shoot them down with great accuracy.
