Teleostei > Gobiiformes (Gobies) > Odontobutidae (Freshwater sleepers)
Etymology: Perccottus:Greek, perke = perch + Gr, kottos = a fish (Ref. 45335). Eponymy: Colonel Nikolay Alexandrovich Glen was honoured because of his efforts that improved the well-being of the Ussuri River area (Ussuriland) of Russia, the type locality. (Ref. 128868), visit book page. More on author: Dybowski.
Asia: Tugur (Sea of Okhotsk) and Amur southward to Yangtze and Fujian. In Amur, historically known from the middle and lower Amur (from Tygda Rive down to the estuary) with tributaries Zeya, Sungari, Ussuri and the Khanka Lake basin. Reported from Shilka in the upper Amur where it is introduced (Ref. 82587). Introduced in Europe (Ref. 59043). At least one country reports adverse ecological impact after introduction (Ref. 2058). 前苏联与亚洲: 中国，俄国, 东北方的韩国与阿穆尔河流域。 至少一个国家报告引入后的不利的生态冲击。
首次成熟时的长度 / 大小 / 重量 / 年龄
成熟度: Lm7.0, range 6 - 8 cm Max length : 25.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 2059); 最大体重: 250.00 g (Ref. 80031); 最大年龄: 7 年 (Ref. 56557)
背棘 (总数) : 6 - 8; 背的软条 (总数) : 9 - 11; 臀棘: 1 - 3; 臀鳍软条: 7 - 10. Distinguished from other European freshwater species by the following characters: 2 dorsals with the first with 6-8 simple rays, and the second with 2-3 simple and 8-12 branched rays; no spines on first dorsal; no barbels; pelvics not fused into a disc; no lateral line canals; males during spawning period, develop a hump on nape and become black with bright green spots on body and unpaired fins (Ref. 59043). Body shape (shape guide): fusiform / normal.
Occurs in lentic waters, lakes, ponds, backwaters and marshes with dense underwater vegetation and avoids river stretches with fast and even slow current (Ref. 59043). Prefers stagnant rivers and bogs (Ref. 80031). Can tolerate poorly oxygenated water and able to survive in dried out or completely frozen water bodies by digging itself into mud where it hibernates. A voracious predatory fish (wide variety of invertebrates, tadpoles and fish) constituting a most serious threat to aquatic fauna wherever it occurs. In small water bodies; known to extirpate almost all other fish species and amphibian larvae. Spawns for the first time at 1-3 years and about 6.0 cm SL. Spawns several potions of eggs in May to June at 15-20°C. Elongated eggs (3.8 x 1.3 mm) with sticky filaments usually deposited in one row close to water surface on underwater structures such as roots, leaves and others. Males guard the eggs and pelagic larvae (Ref. 59043).
