The utility model discloses a testing arrangement of research roe exercise machine reason, be in including basin, setting the water supply unit of basin import department, edge the basin import sets gradually to the direction of export roe releaser, turbulent fluctuation generator in the basin and get the ovum counter, turbulent fluctuation generator and getting is formed with an implantation that supplies the roe implantation between the ovum counter regional. The utility model discloses a simulate natural release of laying eggs the in -process roe, adjusted water body's the velocity of flow and turbulent fluctuation intensity, the motion laws of testable acquisition roe (like drift nature roe and glutinous demersal egg ) under laminar flow and turbulent hydraulic condition, it is easy and simple to handle, this testing arrangement can go on indoor, compares more labour saving and time saving of field investigation method, and is more reliable for its result of numerical simulation means, and the ecological effect assessment who managees has established solid theoretical foundation for fish.
