1992 |
Identified reduced flows and subsequent poor recruitment as the key factor limiting white sturgeon productivity in impoundments. |
1992 |
Determined reservoirs provide large areas of suitable habitat for juvenile and adult white sturgeon, but compensatory population responses may reduce productivity if carrying capacity is exceeded. |
1992 |
Determined over-fishing had occurred in the three lowermost reservoirs of the Columbia. Described appropriate exploitation rates under the reduced productivity resulting from the development and operation of the hydrosystem. |
