What is Chicken grunt (Isaki)?
Isaki is written using a few different character combinations, “鶏魚” (which translates literally as ‘chicken fish’), “伊佐木” and “伊佐幾”. Adult Isaki grows as long as 40 cm. You can find it on the coasts of Japan where there are warm currents. In most cases, fish lose their flavor during the spawning season, but isaki maintains its flavor even when carrying eggs, so it is available to eat during its summer spawning season.
