Hoxmeier, R. J. H. and D. R. DeVries (1996). Status of paddlefish in the Alabama waters of the Tennessee River. North American Journal of Fisheries Management. 16:935-938.
The Alabama waters of the Tennessee River have historically contained abundant populations of paddlefish Polyodon spathula. During the later half of this century, overexploitation has reduced the number of paddlefish in the Tennessee River. We attempted to determine whether paddlefish populations in the Tennessee River within Alabama had recovered from this overexploitation since the implementation of a statewide moratorium in 1988. We failed to collect paddlefish after an effort of 346 gill-net-hours and 20 h of electrofishing pedal time from November 1993 through June 1994. Low abundance of paddlefish in the Tennessee River is likely the result of a combination of continuing commercial harvest in bordering states, loss of habitat, and slow recruitment due to a relatively old age at maturity. Recovery may require additional time, stocking, or both.
