Factors related to occupancy and detection and population demographics of adult Bighead Carp and Silver Carp in the lower Red River catchment.

Birdsall, Benjamin (2023-04-24)

North America native fishes have declined throughout the 20th and 21st century for a myriad of reasons, including invasive species. Two emblematic invasive fishes, Bighead Carp Hypophthalmichthys nobilis, and Silver Carp ...

Introduced Yellow Perch in Lake Martin and Yates Lake, Alabama: Interactions with Native Fishes

Roberts, Craig (2012-07-02)

Yellow perch has been introduced into Southeastern US drainages outside its native range. In Alabama, established populations now exist in Lake Martin and Yates Lake. Here, I determined how yellow perch might influence ...

Investigating Interactions Between Channel Catfish and Other Sport Fishes in Alabama’s State Public Fishing Lakes

Leonard, David (2009-05-15)

Channel catfish Ictalurus puntatus is a popular sportfish maintained by annual stocking in Alabama's State Public Fishing Lakes. Channel catfish may negatively affect bluegill Lepomis macrochirus and largemouth bass ...

Mercury Bioaccumulation Patterns in Two Estuarine Sportfish Populations

Farmer, Troy (2008-12-15)

Mercury (Hg) is a harmful bioaccumulative heavy metal to which humans are exposed primarily through fish consumption. Several consumption advisories for mercury have been issued for fishes along the US Atlantic and ...

A metabolic approach to assessing interactions between climate change, agrochemicals, and freshwater mussel reproduction

Gibson, Rebecca (2019-04-16)

Unionid mussels are a fundamental part of stream ecology yet are one of the most threatened aquatic organisms due in part to habitat loss, stream fragmentation, and deterioration. The increasingly relevant effects of climate ...

Migratory Characteristics and Passage Efficiency of Fishes at Two Dams on the Alabama River, Alabama

Simcox, Brandon (2012-04-04)

Fish passage facilities are a widely accepted mitigation tool at many dams in the United States to assist migratory fish species to upstream spawning areas on the U.S. Atlantic and Pacific coasts. Here we investigated the ...

Mortality components for two Micropterus spp. in a Southeastern reservoir: a high-value reward and radio telemetry approach.

Rubino, Max (2024-04-25)

For black bass species (Micropterus spp.) post-release mortality rates are higher for tournaments than non-tournaments and may be a significant component of total fishing mortality. On Neely Henry Reservoir in Alabama there ...

Nursery Habitat and Hatch Dates of Large River Fishes of the Lower Red River Catchment

Ramsey, Paul (2023-04-27)

Many freshwater fishes in North America are of conservation concern. Both fine-and coarse-scale physicochemical conditions affect the quantity and quality of nursery habitat and can influence the hatches and growth of ...

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 ...

Persistence of fish assemblages on sand and gravel bar habitat in the Alabama River, Alabama

Haley, Timothy (2012-04-19)

The Alabama River is a biologically diverse system containing over 180 native fishes and at least 33 endemics. Many studies have surveyed species of conservation concern, such as the federally endangered Alabama Sturgeon ...

Privately-Owned Small Impoundments of Central Alabama: A Survey and Evaluation Of Management Techniques and Enhancements

Haley, Norman, III (2009-07-15)

Small impoundments are abundant and widespread throughout central Alabama, and support a large portion of recreational fishing effort. Because the quality of fishing in these ponds is directly related to the management ...

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 ...

Reconstructing the Past Salinities Experienced by a Freshwater and Marine Piscivore in the Mobile-tensaw River Delta Using Otolith Microchemistry

Lowe, Michael (2007-12-15)

In this study, we used changes in otolith microchemistry, with particular emphasis on otolith Sr:Ca, along the otolith growth axis to examine the past salinities, and thus the past environments, experienced by age-0 ...

The Relationship Between Shoreline Development and Resident Fish Communities in Lake Martin, Alabama

Purcell, Thomas (2011-04-06)

Many reservoirs in the southeastern U.S. have experienced an increase in human development along its shorelines. This development often includes armoring the shoreline with either bulkheads or riprap to reduce erosion and ...

Response of Aquatic Biota to Changing Land Use Pattern in Streams of West Georgia, USA

Helms, Brian (2008-05-15)

Watershed land use change is one of the most pervasive influences facing streams in the southeastern United States. In particular, watershed urbanization has a potentially dramatic impact on stream biota. Through direct ...

A Study of Native and Introduced Clupeids in Mobile River Basin Reservoirs

Bart, Ryan (2018-06-05)

In 2010, Blueback Herring Alosa aestivalis, a nonnative species were first found in Lewis Smith Lake, Alabama. Since this initial discovery, Blueback Herring have been found in several other waters in Alabama including ...

Supplemental Feeding of Bluegill as a Small Impoundment Enhancement for Largemouth Bass

Woodard, Stephen (2011-04-01)

Several pond enhancements are commonly used to increase fish production or enhance angling opportunities. I investigated whether providing supplemental feed to bluegill leads to higher reproductive rates, and if the ...

Swimming Performance of Coastal and Inland Largemouth Bass at Varying Salinities

Klimah, Carl (2015-12-04)

Coastal estuaries represent an interface between marine and fresh waters, and, as such, they are exposed to seasonal and annual fluctuations in salinity. All of the organisms that live in estuaries must emigrate or endure ...

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 ...
