What is Ainame アイナメ【鮎並】?

Ainame is a popular fish in Japan, which prefers low-salt sea regions and is widely distributed along the coast of Japan. In addition to its use for sushi and sashimi, it is also an ingredient in many other dishes of Japanese cuisine.

Ainame as an ingredient for Sushi and Sashimi

The meat of the Ainame is white, has a slightly sweet mild, yet aromatic flavor. The meat owes its strikingly light color to its high fat content. The texture is firm and elastic, but not tough. Fresh fish is preferred for the preparation of sashimi, but is also well suited for the preparation of ainame nigiri. The skin is delicious and fatty, which is why ainame in aburi (炙り) style is also a perfect alternative for sushi or sashimi. This is done by either flaming the skin to a crisp with a blowtorch or pouring hot water over it while leaving the rest of the meat raw.

Best Season

The taste is quite stable throughout the year, with the best season being from spring to summer, when the fish are more fatty and aromatic. Top specimens trade at remarkably high prices at this time of year.

Characteristics & Ecology

Ainame prefers rocky coastal areas, shallow water below the tidal zone, occasionally also artificial reefs if covered by algae or seaweed. The distribution area extends along various parts of Japan except the Nansei Islands to the Korean Peninsula, the Yellow Sea coasts and southern Sakhalin. They usually reach a length of about 57 centimeters and weigh about 5 pounds. They are usually found on rough soils at depths of 140 to 155 meters. It is a nocturnal species that lives territorially in rocky coastal areas. They feed mainly on smaller fish, snails, mussels and crustaceans. It has a certain importance for Japanese commercial fishing.

The spawning season is from late autumn to winter. In the colder waters of Hokkaido it starts already in September and ends in November. At this time of year the scales of the male take on a golden color, which is called wedding color (koninshoku, 婚姻色、こんいんしょく). During this time, the males migrate into shallower water and form precincts there, in which they guard and care for the eggs fastened at small rocks. Although the males are responsible for the brood care, it was observed occasionally that they partially eat the carefully maintained eggs. The reason for this cannibalism is not yet conclusively clarified by science (Munehara & Miura, 1995).

Ainame in Japan

Looking at the Japanese kanji characters of ainame (鮎並) and ayu (), it is noticeable that the kanji for ainame contain the character of ayu. It is commonly said that this is due to the fact that ainame males protect their brood as vigorously as an ayu. Now and then one comes across the claim that the character is a reference to the fact that an adult ainame resembles an ayu. However, even at a quick glance it can be seen that these fish have very little in common.

Economy

In the market mainly individuals with a length of 30 to 40 cm can be found, occasionally they reach a size of up to 60 cm. The economic importance is low, in Japan a commercial breeding in aquacultures takes place sporadically. The most common fishing methods include by-catch in trawls, gillnets or pots. Furthermore, ainame is a popular catch for sport fishing.

The economic importance in relation to large-scale fisheries is so small that the Food and Agriculture Organization of the United Nations (FAO) does not explicitly include ainame (lat. Hexagrammos otakii) in its statistics.
