Short description
आकृति विज्ञान | मौरफोमैटरिक्स
पृष्ठीय रीढ़ (सम्पूर्ण): 7; पृष्ठीय सौफट रेज़ (सम्पूर्ण): 8-9; गुदा कांटा 1; ऐनल सौफट रेज़: 8 - 9. This species is placed under Hyrcanogobius on the basis of slightly different organization of cephalic sensory pores (Ref. 59043).
This near-pelagic coastal marine species is found in areas with different salinities, including freshwater. It lives for a year and matures at 18-20 mm SL. Spawns after first winter, May-June, down to 2-7 m, with females probably laying 2-3 portions of eggs (0.4-1.0 mm), separately attached inside a mollusc shell; and adults dying soon after spawning. Feeds on small crustaceans (Ref. 59043).
Females probably lay 2-3 portions of eggs (Ref. 59043).
