Biotic and abiotic factors affecting the distribution of Paddlefish Polyodon Spathula in William “Bill” Dannelly Reservoir and the Cahaba River, Alabama.
(2023-12-06)
Paddlefish Polyodon spathula river section use, and summer backwater use (where zooplankton is thought to be abundant) vary seasonally. I quantified Paddlefish habitat use in Dannelly Reservoir, Alabama, which includes the ...
Coinfection dynamics of experimentally challenged channel catfish (Ictalurus punctatus)
(2023-04-28)
Catfish farming is the largest sector of the U.S. aquaculture industry and is of paramount economic importance for Southern U.S. agriculture. Maintaining and improving catfish health is a primary concern for producers, and ...
Cryptic Tolerant Species and Their Potential Effect on Index of Biotic Integrity (IBI) Scores, with the Presentation of an Alternative Metric of Stream Health
(2023-04-17)
Metrics such as the Index of Biotic Integrity (IBI) are often used by management agencies to estimate the abstract property of stream health. These metrics are usually predicated on the belief that certain fish species are ...
Development of intensive indoor rearing strategies for largemouth bass (Micropterus salmoides) during critical early life history stages
(2022-07-25)
Largemouth bass (LMB), Micropterus salmoides, is arguably the most sought-after
recreational fish in the United States. Recently, there has been rising interest in LMB as a food
fish and current production techniques ...
Distribution, Relative Abundance, and Habitat Association of Tallapoosa Bass Micropterus tallapoosae in the Tallapoosa River Drainage, Alabama.
(2021-07-16)
The diversity of freshwater fishes and black bass Micropterus spp. in the United States are concentrated in the southeastern region. Dams, anthropogenic land use, fragmentation, invasive species and other factors are ...
Distribution, Relative Abundance, and Habitat Associations of Warrior Bass in the Black Warrior Watershed, Alabama
(2022-07-26)
Single season occupancy and zero inflated poisson models were used to identify relationships between Warrior Bass Micropterus warriorensis occurrence, relative abundance, and multiscale habitat factors. Warrior Bass ...
Ecology of crayfishes in the Ozark Highlands ecoregion of Oklahoma
(2023-04-27)
Crayfishes aid in the transfer of nutrients through aquatic ecosystems and are prey to
many aquatic and terrestrial species. Although their importance in ecosystem dynamics is
generally well recognized, information ...
