Etymology: Knipowitschia: Because of N.M.Knipowitsch, a zoologist and Russian ichthyologist from the Academy of Sciences. Expeditions in "Pomor" and "Pervosvanniy" ships to Azov and Black sea (1898-1908).

Eurasia: Brackish portions of the Black Sea, Sea of Azov and Caspian Sea.

Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 2.0 range ? - ? cm
Max length : 5.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 2058); 3.5 cm TL (female)
背棘 (总数): 6 - 8; 背的软条 (总数): 7-9; 臀棘 1; 臀鳍软条: 8 - 9. This species is distinguished from its congeners by the following characters: upper part of caudal fin longer than the lower part; anterior extremity of anterior oculoscapular canal in front of middle of eye; no posterior oculoscapular canal; back unscaled in front of origin of second dorsal; breeding males with 4-8 dark bars when alive; total scales in midlateral series 33-40 (Ref. 59043).
Occur in shallow water, on sand and among weeds (Ref. 4696). Live less than 2 years. Feed on small benthic invertebrates (Ref. 59043). Spawn after first winter. Females may spawn several times during a season. Males defend eggs in cavities under stones, plant material or molluscs shells (Ref. 59043) like underside of lamellibranch valves (Cardium, Monodonta, Unio, etc.) (Ref. 4696). Eggs hatch at 3.0-3.8 mm (Ref. 59043).
出现于浅水区, 在沙子上与在杂草之中.(参考文献 4696)

Bayesian length-weight: a=0.00977 (0.00442 - 0.02163), b=3.05 (2.86 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Generation time: 1.7 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
回复力 (Ref.
