![]() The anterior end of the organ has three long median projections, with the central extension the longest. Japanese whiting have a swim bladder characterised by a single, long posterior extension which tapers to a slender point. Like all species of sillaginid, the swim bladder is the most dependable diagnostic feature. The species has a known maximum length of over 30 cm (11.8 in). Other distinguishing features include 70 to 73 lateral line scales and a total of 35 vertebrae. The anal fin is similar to the second dorsal fin, but has 2 spines with 22 to 24 soft rays posterior to the spines. ![]() The first dorsal fin has 11 spines and the second dorsal fin has 1 leading spine with 21 to 23 soft rays posterior. The body is covered in small ctenoid scales extending to the two rows of cheek scales and head. Description Īs with most of the genus Sillago, the Japanese whiting has a slightly compressed, elongate body tapering toward the terminal mouth. The species is locally known as Shiro-gisu in Japan and Chin-Sa-Suo in China. The binomial and common name of the species refers to the country where the species was first described from Japan, although its range has subsequently found to be much wider than just Japan. Studies into various aspects of the Japanese whiting's biology have also been incorrectly named as studies on S. The species has often been mistaken for Sillago sihama, and erroneously been published under this name by a number of authors, the first being Steindachner and Döderlein in 1885. The species was first recognized and scientifically described by Temminck and Schlegel in 1843 based on a holotype taken somewhere along the Japanese coast. The smelt-whitings are Perciformes in the suborder Percoidea. The Japanese whiting is one of 29 species in the genus Sillago, which is one of three divisions of the smelt whiting family Sillaginidae. Being one of the most abundant species of fish around Japan, they make up a large percentage of the commercial catch. They spawn between June and October, and are taken in large quantities during this period by fishermen. The species inhabits a variety of shallow water habitats where it preys on a variety of crustaceans as well as polychaetes, bivalves and small fish. As suggested by its name, the Japanese whiting was first recorded from Japan in 1843, but has subsequently been found to extend to Korea, China and Taiwan. The Japanese whiting, Sillago japonica, (also known as the Japanese sillago or Shiro-gisu) is a common species of coastal marine fish belonging to the smelt-whiting family, Sillaginidae. ![]()
