Matters about population of Sturgeon fishes based on big water basins
Sturgeon fishes populate on waterbasins included low salt contents based on "Hydrodynamic Conditions" as common.As ecosystem,I say with individual experiments to expressed to extreme sense regions against to Chlorophyll-a impact on "manmade effects" of this type water basins. You are right!Summarying as manmade effects among main causes of big decreasing cond. considering actual times of this types populated as dense on ancient times for basins as Adriatic,BlackSea,Azov,Hazar.
In the other hand,citing especially to "selective a stru." for increment of this type fishes!!!(So,knowing "sense behaviour" of this creatures for dreinage routes as wide freshwater beds on sedimentary matters)
Very thanks...
Thus,I will wait to precious replies on experiments of geoenvironmets related
