SPAWNING PERIOD 

 References containing data on spawning period include both statements 

 regarding the dates on which spawning activity was observed or was about 

 to occur, and those statements of the duration of spawning period. 

 It is to be noted that remarks regarding the duration of spawning period 

 may be only approximations based on duration and/or peak of upstream migration, 

 and not on direct observation of spawning fish.
