生態學
; 淡水; 半鹹淡水 底中水層性. 溫帶; 4°C - 20°C (Ref. 2059); 49°N - 40°N, 25°E - 54°E
Eurasia: Widespread all over the Marmara, Black and Caspian seas basins; inhabits mostly fresh- and brackish waters with low salinity (<2%).
歐亞大陸: 黑海，亞速海，裡海與支流。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm ?, range 6 - ? cm
Max length : 16.2 cm TL 雄魚/尚未辨別雌雄; (Ref. 2058); 最大年齡: 5 年 (Ref. 59043)
背棘 (總數) : 7 - 8; 背的軟條 (總數) : 14 - 18; 臀棘: 1; 臀鰭軟條: 12 - 16. This species is distinguished from its congeners entering freshwater in Europe by the following characters: irregular position and shape of diagonal bars on body; first branched ray of second dorsal about as long as penultimate ray; no scales on midline of nape, in front of preoperculum; pelvic-disc fraenum with small rounded lobes and the length is less than 1/6 of width at base; scales in midlateral series 54-62 + 2-3; posterior part of first dorsal without black spot (Ref. 59043).
Occurs in brackish- and fresh-water habitats with low salinity (< 2 ppt); lagoons and lakes; large rivers to small, fast-flowing streams; on sand or mud bottom; mainly in well vegetated or high-complexity habitats. Abundant in backwaters and still channels (Ref. 59043). Longevity is 4-5 years; spawns for the first time at 2 years; spawning season in April to June, occasionally until mid-August; females may repeat spawning during a season; usually spawns for a single season. Males guard eggs until hatching; with adhesive eggs deposited on stones, shells and aquatic plants (Ref. 59043). Feeds on crustaceans (esp. Corophiid amphipods), aquatic insects (mostly chironomid larvae), polychaetes, also small fish and mollusks (Ref. 4696).
出現於河川下游與岸邊潟湖, 非中鹽度的; 在沙或泥上。 吃甲殼動物 (esp。 corophiid 片腳類動物), 水生昆蟲 (大部份寶刀魚仔魚), 多毛類動物, 也小魚與軟體動物.(參考文獻 4696)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00423 - 0.01184), b=3.09 (2.95 - 3.23), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref.
93245).
營養階層 (Ref.
69278): 3.3 ±0.3 se; based on diet studies.
Generation time: 1.8 ( na - na) years. Estimated as median ln(3)/K based on 1
growth studies.
回復力 (Ref.
120179): 高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
