FBname: Eastern tubenose goby
Comments: Inhabits a variety of slow-flowing or still waters; usually associated with dense vegetation or coarse rocks.  Spawns for the first time at 1-2 years, and usually only for 1 to 2 seasons, April-August with females spawning more than once during a season.  Males guard the eggs which are deposited in cavities; larvae and juvenile are benthic.  Feeds on benthic invertebrates.  It is invasive in Volga where reportedly, the spreading was due to canalization of main river and reservoirs or slow-flowing waters created by hydroelectric plants (Ref. 59043).
