Etymology: Pseudorasbora: Greek, pseudes = false + Rasbora, an Indian word for a fish, also used in Malay peninsula; pugnax: The specific name, pugnax, is Latin for belligerent, aggressive, pugnacious. Mature males defend their territory very aggressively during breeding season. This species is locally called ‘Kenka-Moroko’ (kenka means fighting in Japanese) (Niwa, 1967). Thus, the name alludes to the behavioral characteristics of this species..

deskripsi pendek Morfologi | Morfometrik

duri punggung lunak (Keseluruhan (total)): 10; Sirip dubur lunak: 9; vertebrata, bertulang belakang: 33 - 34. Pseudorasbora pugnax can be diagnosed from other Japanese congeners by having a faint dark stripe on the flank which disappears in females and poorly-developed nuptial tubercles in adult males. It differs from P. parva in having longer head (27.5-31.9 % SL vs. 23.5-27.3), lateral line incomplete (vs. complete), infraorbital, supraorbital and supratemporal canals of the cephalic lateralis system incomplete (vs. complete). It can be further distinguished from P. pumila in having 33-34 vertebrae (vs. 34-35), infraorbital canal of cephalic lateralis system developed (vs. undeveloped) with a rostral branch present (vs. absent), nasal canal present (vs. absent) and mandibular canal complete (vs. incomplete) (Ref. 103407).

Occurs in deep irrigation canals and ponds (1-2 m depth) with emergent plant growth. Spawns from late March to early July and preferentially lays eggs under stones (< 200 cm3 volume) in shallow water (< 40 cm depth) (Ref. 103407).
