Effects of Rostrum Injuries on Body Condition, Dam Passage, and Hydrodynamics of Paddlefish (Polyodon spathula) in the Alabama River 

Steffensmeier, Nathaniel (2024-04-05)  ETD File Embargoed
The rostrum of Paddlefish (Polyodon spathula) aids in finding zooplankton prey as well as provides lift and stability during swimming, but this structure can sometimes be damaged or even completely missing. Injury or loss ...

Estimation of Survival of the Atlantic Horseshoe Crab, Limulus polyphemus, by Analysis of Mark-Recapture Data with Tag Loss 

Butler, Catherine Alyssa (2012-12-17)
The Atlantic Horseshoe crab, Limulus polyphemus, is a valuable resource along the Mid-Atlantic coast which has, in recent years, experienced new management paradigms due to increased concern about this species role in the ...

Evaluating Methods for Estimating Delaware Bay Limulus polyphemus Abundance 

Merritt, Emily (2015-08-18)
Monitoring is an essential component of wildlife management. In the United States, Atlantic horseshoe crabs (Limulus polyphemus) are harvested and relied upon by several user groups in mid-Atlantic states, and managers ...

Passage and Fine Scale Movements of Paddlefish and Smallmouth Buffalo near Claiborne Lock and Dam 

McKee, Dustin (2019-07-10)
Dams often impede spawning migrations of fishes, concentrating adults in their tailwaters. Little is known about behavior of migrating fishes as they approach dams, including where fish are located in the tailrace, their ...

Quantifying fish swimming performance and behavior in two diverse environments: a multifaceted approach. 

Hershey, Henry (2019-07-11)
In the southeastern United States, low-head dams are common and the effects of these structures on migratory fishes are relatively unknown. Studying how migratory fish behave in habitats altered by dams such as the upstream ...

The swimming performance of Freshwater Drum (Aplodinotus grunniens) below Claiborne Lock and Dam and in various temperature and dissolved oxygen treatments 

Laubach, Colin (2020-07-24)
Alterations to temperature and dissolved oxygen regimes in the tailwaters below dams can cause harmful stress to fish. Although Freshwater Drum Aplodinotus grunniens are widespread in rivers across North America, this ...

Using physiological approaches to quantify potential effects of anthropogenic alterations to river systems on fishes 

Stell, Ehlana (2024-04-13)  ETD File Embargoed
In this dissertation, I used an ecophysiological approach to study the effects of dams on fishes via studies on swimming performance, metabolic rate, and thermal tolerance. The first study focused on 4 fish species (Channel ...
