An attempt is made to demonstrate that the availability of fish to the angler in TVA reservoirs is not strictly correlated with their relative abundance. Crappie, which are subjected to much heavier fishing pressure than bass, are caught at a much lower rate as demonstrated by creel census and return of tagged fish. It is suggested that it may be possible to calculate a factor for differential availability of fish.
