Slide 3: Methods
Methods ¡ Netting and tagging operations were completed below Millers Ferry Lock and Dam in March and April. ¡ Most fish were measured, weighed, and their gender was determined, if possible. ¡ A sonic tag was implanted in the abdominal cavity. ¡ A numbered anchor tag was inserted through the left si

Slide 7: Southeastern Blue Sucker (SBS) Results
Southeastern Blue Sucker (SBS) Results 1. 940 fish were collected from 1995-2002. 2. Males outnumbered females 2:1. 3. Males live 34 years; females live 32 years. 4. Spawning occurred below Millers Ferry when water temperatures reached 16°-21°C. 5. 128 (20%) of 643 fish anchor tagged from 1995-2001

Slide 15: Paddlefish Results
Paddlefish Results 1. 17 fish paddlefish were tagged below Millers Ferry in 2002. 2. 13 fish were found within 50 miles of Millers Ferry. 3. Two fish moved downstream past Claiborne. a) One fish ranged from ARM 63 to ARM 73. b) The second fish was detected in the Mobile River- approximately 137 mile

Slide 18: Conclusions
Conclusions 1. SBS, paddlefish, and other riverine fish species will move pass Claiborne LD provided the spillway is inundated by spring floods. 2. Fish cannot move past Millers Ferry unless the gated spillway is inundated. 3. As such, fish species inhabiting the Alabama River are effectively isolat
