EOL Text
This taxon is one of a number of demersal species in the Amur River system. Demersal river fish are found at the river bottom, feeding on benthos and zooplankton
The persistence of mercury contamination in Amur River bottom sediments is a major issue, arising from historic cinnabar mining in the basin and poor waste management practises, especially in the communist Soviet era, where industrial development was placed ahead of sound conservation practises.
The largest native demersal fish species in the Amur River is the 560 centimeter (cm) long kaluga (Huso dauricus); demersal biota are those that inhabit the bottom of a surface water body. Another large demersal fish found in the Amur is the 300 cm Amur sturgeon (Acipenser schrenckii), a taxon which is endemic to the Amur basin.
Other demersal endemic fish species (all in the concubitae family) of the Amur Basin are Iksookimia longicorpa, I. koreensis, I. hugowolfeldi, Cobitis melanoleuca melanoleuca and the Puan spine loach (Iksookimia pumila).

Non-Migrant: No. All populations of this species make significant seasonal migrations.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.
Inhabits muddy and sandy bottoms along the shore of bays and estuaries, sometimes ascends rivers. Oviparous, spawn in winter to early spring (Ref. 205). Eggs are deposited in Y-shaped nests (Ref. 205). Used in Chinese medicine (Ref. 12166).

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

The species has a northwest Pacific distribution. It is known from coastal waters of Siberia (Reshetnikov et al. 1997), the Korean Peninsula (Kim et al. 2005), Japan (Masuda et al. 1984), Chinas mainland (Eschmeyer et al. 1983) and northern Viet Nam (Kuronuma 1961). Introduced in Australia, Mexico and USA (Welcomme 1988, Lever 1996).

Inhabits muddy and sandy bottoms along the shore of bays and estuaries, sometimes ascends rivers (Ref. 559). Larvae and juveniles (0.9-1.3 cm SL) took mainly small planktonic animals, while newly settled and benthic juveniles (1.4-2.0 cm SL) consumed predominantly small benthic or epiphytic crustaceans, along with polychaetes. The contribution of polychaetes to the diets increased in larger individuals (2.1-5.3 and 5.4-11.4 cm SL). (Ref. 53631).
