Ecology
Marine; freshwater; brackish; benthopelagic. Temperate; 58°N - 34°N, 120°E - 161°E
Asia: Korean Peninsula, Japan, Kuril islands, Amur basin and Kamchatka Peninsula.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 6.5 cm SL male/unsexed; (Ref. 50519); 9.0 cm SL (female)
Length in freshwater is recorded at 6.5 cm TL; in the sea, it is recorded at 8.5-9.0 cm TL (Ref. 2058). Males build, guard and aerate the nest where the eggs are deposited (Ref. 205).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00479 (0.00240 - 0.00955), b=3.02 (2.84 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec < 1,000).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
