The effects of temperature and dissolved oxygen on fish respiration determined by enzymatic and organismal techniques
(2021-04-16)
One of the greatest threats to freshwater biodiversity is anthropogenic alteration to habitat. Temperature change is one of the most important anthropogenic impacts, especially for ectotherms that experience the effects ...
Enhancing the efficiency of hybrid catfish (♀ channel catfish, Ictalurus punctatus, × ♂ blue catfish, I. furcatus) embryo production through xenogenesis
(2023-05-01)
Xenogenesis has been identified as an innovative technology for hybrid catfish (♀ channel catfish, Ictalurus punctatus × ♂ blue catfish, I.furcatus) embryo production. The xenogeneic process can be accomplished by transplanting ...
Epigenomic and transcriptomic alterations of channel catfish exposed to DNA methyltransferase inhibitor and estradiol
(2021-07-23)
Teleost fish exhibit a great level of diversity of sex determination. With channel catfish (Ictalurus punctatus), a lower teleost, sex determination genes have not been identified. However, the sex determination region ...
Essential amino acid balance in channel catfish Ictalurus punctatus diets
(2021-12-02)
Channel catfish are among the top cultured aquaculture species in the U.S. Protein is an important factor in catfish feeds to allow for proper health and development and accounts for 50%-60% of the total feed cost. Due to ...
Establishing Energetic Cost of Acute Exposure to Select Anthropogenic-Caused Environmental Conditions in the North Gulf of Mexico Derived Eastern Oyster (Crassostrea virginica)
(2024-04-16)
Oyster aquaculture is an important industry in the Gulf of Mexico and has seen a significant increase in interest over the last 20 years. Because oyster farming takes place in ambient waters, farmed oysters are subjected ...
Evaluating the effects of three Alabama River dams on fish movements and population connectivity using otolith microchemistry
(2022-04-20)
Dams impede fish movement and can isolate riverine populations into defined areas. The Alabama River is divided into four major sections by three lock-and-dam structures. I used otolith microchemistry to quantify movements ...
Evaluating Tradeoffs Between Fishing Quality and Economic Performance in a Reservoir Black Bass Fishery with High Tournament Effort
(2024-04-24)
Black bass Micropterus sp. populations are subject to high catch-and-release angling effort and higher post-release mortality partly attributable to the popularity of fishing tournaments. Increasing stakeholder conflicts ...
Evaluating various management strategies of biofloc systems and understanding the physiological basis behind the thermal tolerance of Pacific white shrimp, Litopenaeus vannamei in low salinity waters
(2023-04-28)
Biofloc technology (BFT), in its various types, has been known to be a realistic solution for efficiently managing water quality with low or no water exchange, enhancing shrimp growth performance and establishing an efficient ...
Evaluation of an alternative salt mixture and the levels of magnesium in low salinity water for Pacific white shrimp Litopenaeus vannamei
(2021-04-12)
One of the primary challenges faced by inland shrimp farmers today is the higher cost of reconstituted sea salts (RSS) which represents a considerable financial burden considering the volume of salt necessary for the ...
An Evaluation of Carbon Dioxide and Water Flow as Control Techniques for the Invasive Red Swamp Crayfish
(2022-04-26)
The Red Swamp Crayfish (RSC) is an invasive crayfish species that has invaded many
water bodies in North America and other continents. Recent work has demonstrated the potential
of carbon dioxide (CO2) as a tool to ...
Evaluation of dietary immunostimulants and probiotics on growth performance and health indices of channel catfish, tilapia, and shrimp.
(2023-08-07)
Channel catfish, Nile tilapia, and whiteleg shrimp are three major aquaculture species worldwide. Growth performance and disease mortality are common bottlenecks within these culture systems. Feed supplementation with ...
Evaluation of mechanical removal rates for rehabilitating over-crowded largemouth bass Micropterus salmoides populations in Alabama small impoundments
(2021-07-15)
Largemouth bass Micropterus salmoides populations in small impoundments exhibit poor growth and body condition under high population densities typically found in unmanaged ponds. The effectiveness of largemouth bass harvest ...
Evaluation of probiotic effects on the growth performance of Nile tilapia (Oreochromis niloticus) in a high-density biofloc system.
(2023-07-31)
Biofloc technology (BFT) is an aquaculture production system that has gained popularity with tilapia producers. Probiotics provide benefits for the host and/or the environment. Probiotics have been reported in some cases ...
Examination and Evaluation of the Persistence of Virulent Aeromonas hydrophila, Edwardsiella ictaluri and Flavobacterium covae Within the Sediments of West Alabama Commercial Catfish Ponds
(2023-04-26)
The three most prevalent bacterial pathogens responsible for channel (Ictalurus punctatus) and hybrid [♀ channel catfish (I. punctatus) × ♂ blue catfish (I. furcatus)] catfish losses are virulent Aeromonas hydrophila (vAh), ...
Factors related to occupancy and detection and population demographics of adult Bighead Carp and Silver Carp in the lower Red River catchment.
(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 ...
Feeding ecology and lethal thermal tolerances among selected North American freshwater mussels (Order: Unionida)
(2022-05-04)
Sixty-five percent of North American unionid mussel species are considered imperiled. Knowledge gaps persist in unionid feeding ecology and lethal thermal tolerance limits which could aid in the conservation and management ...
Fish Kill Loss Valuation through Estimation of Angling Effort and Use Valuation on Three Mid-Size Alabama Rivers
(2022-07-25)
State fisheries management agencies seek financial restitution following a fish kill. Economic losses due to fish kills on rivers have been underestimated in Alabama, as user loss values have not been included as a loss ...
