Leucopsarion petersii is a goby species from the subfamily Gobionellinae and the only representative of the monotypic genus Leucopsarion . The species occurs in the northwestern Pacific on the coasts of China , Japan and Korea . The common name is Japanese シロウオ Shirōo .

description

The goby has a thin, elongated body up to 13 centimeters in length. The species is neotenic , so it retains a larval shape even when the animals are sexually mature. The individuals of this kind are scaly, have a swim bladder and only a small ventral fin ; Most gobies develop dandruff at sexual maturity, lose their swim bladder and develop a larger ventral fin. The body of Leucopsarion petersii is transparent. Spawning may be seen inside the body. The species has a sexual dimorphism , females are larger than males.

The generic name is composed of the Greek word Leukos (for white - due to the pale, translucent body) and opsarion (meaning: "Fish eaten with bread"). This naming is also reflected in the Japanese name シロウオ Shirōo . The species name honors Wilhelm Peters , a German naturalist who published the original description of the species by the zoologist Franz Hilgendorf .

Occurrence

There are two separate populations. One is located in the Sea of Japan , the other directly in the Pacific Ocean . The separation of these populations is due to the course of the Japan Current and its branch, the Tsushima Current . In the overlapping area of the populations , the respective representatives can cross with each other. Individuals from the Sea of Japan are usually larger and have more vertebral bodies.

Way of life

During the life phase in the ocean, the goby feeds on animal and vegetable plankton . It is an anadromous species of fish that migrates from the sea, the growth biotope, into fresh water, the spawning environment. It spawns in rivers and the individuals involved in the spawning business die afterwards. The animals do not eat any more during the migration.

fishing

The goby is a popular food fish in Japan and South Korea , where it is traded at high prices. The animal is usually eaten raw and sometimes still alive, this is known as odori-gui ( Japanese 踊り食い , dancing food ).
