The maximum body length of males is 6.5 cm, females are 9. Dorsal spines: 7β11 (usually 9), soft rays in the dorsal fin 8β13, anal spines 1, soft rays in the anal fin 7β11.
Distributed in Asia: the Korean Peninsula , Japan , the Kuril Islands , the Amur basin and Kamchatka . Freshwater, saltwater or marine benthic fish [3] . Amur stickleback prefer rivers and lakes with clean, slow or calm water and areas with vegetation where they can build their nests. The flow velocity is very important for these fish - if the current near the surface becomes faster than 0.5 m / s, their population can be greatly reduced. This fish is found at a water temperature of 4.7β25 Β° C, but 14β16 Β° C is optimal for it.
The Amur stickleback feeds on mysids, amphipods, and other bottom and bottom organisms [4] .
Amur stickleback begins to breed after two years. The time required for the incubation of eggs depends on the temperature of the water: at a temperature of about 18.5 Β° C, fry are hatched after about 5 days.
Although the species is widespread throughout East Asia and the eastern part of Russia, its habitat is threatened by pollution and the construction of flood control structures and dams that can change the speed of rivers. These changes make the habitat unsuitable for this species, which may lead to its extinction. It is believed that over the past 10 years the population of the species has decreased by 30% and this process will continue.
Harmless to humans and does not have commercial value [5] . Penetrating into the ponds where valuable fish are bred, it can cause damage by eating their eggs.
