Reproductive Confinement of Common Carp, Cyprinus carpio, and Channel Catfish, Ictalurus punctatus, via Transgenic Sterilization
(2012-12-05)
Transgenic animals had shown great potential for increasing growth rate, ability to resist disease, and for use as tool to research in forward and reverse genetics. Genetically modified animals could pose ecological risk ...
Resource Use and Waste Production at a Semi-Intensive Black Tiger Prawn Penaeus Monodon Farm
(2007-08-15)
A study of resource use and waste production was conducted at the Aqualma shrimp farm in Madagascar . This farm has 685 ha of grow-out ponds where black tiger prawn Peneaus monodon are produced by semi-intensive production ...
Role of water availability on fish assemblage structure: effects of agricultural land use and spawning mode
(2012-04-09)
The availability of water has been changing as human demands increase, weather patterns change, and land use is altered. This is a common trend throughout the world as well as in the tributaries of the Middle Chattahoochee ...
The Roles of Acoustic and Visual Signals in the Reproductive Behavior of the Federally Threatened Pygmy Sculpin, Cottus paulus, (Cottidae)
(2009-07-02)
Animals use many modes of communication (i.e. tactile, visual, acoustic and chemical) for territory defense, resource defense, and/or courtship. These communication systems can be used singularly or combined together, such ...
Satiation Feed Consumption as an Inventory Tool to Assess Biomass of Channel x Blue Hybrid Catfish in Earthen Ponds
(2011-11-15)
The present study was conducted to determine the percentage body weight of feed
that specific sizes of hybrid catfish consume at various water temperatures when fed to
satiation under pond conditions. This information, ...
Second generation of catfish genetic linkage map and integration of catfish genetic linkage and physical maps using BAC-anchored microsatellites
(2012-07-17)
Integration of physical and linkage maps is a critical step in building necessary genome resources for fine mapping of QTL, comparative genomics, and accurate and efficient whole genome assembly. Previously, we have ...
Shifting Relationships Between Crayfish and Symbiotic Worms in Surface Water and Subterranean Environments
(2013-08-22)
Branchiobdellidans are small annelids (Clitellata) that have neutral, positive, and negative effects on stream crayfishes. Host effects are context dependent, with positive effects (increased survivorship and growth) ...
Shoal occupancy estimation for 3 lotic crayfish species in the Tallapoosa River basin, Alabama
(2010-04-08)
The greatest diversity of crayfishes in the world is in the southeastern United States; however many species are at risk and lack of information on habitat requirements and the effects of habitat alteration hamper crayfish ...
Sound Production And The Effect Of Noise On Communication In The Blacktail Shiner (Cyprinella venusta)
(2012-06-06)
Animal communication is important in the success and survival of species. In order to find a potential mate, individuals must be able to communicate effectively with each other. This communication may involve identification ...
Stage-specific responses to freshwater mussels to temperature and suspended solids
(2013-04-22)
Elevated levels of suspended solids (TSS) are one of the most widespread water quality problems in streams, rivers, and lakes throughout North America, yet little is known about their effect on populations of freshwater ...
Studies for Improvement of Reproductive Biotechnology for Production of Channel Catfish (Ictalurus punctatus) Female X Blue Catfish (Ictalurus furcatus) Male Hybrid Embryos
(2012-12-10)
Investigative studies were conducted on the relative effectiveness between carp pituitary extract (CPE), luteinizing hormone releasing hormone analog (LHRHa) injections and LHRHa implants for producing hybrid catfish ...
Studies on the digestive gland microbiome of freshwater mussels
(2019-04-16)
Freshwater mussels are among the most imperiled aquatic invertebrates in North America. In the United States, Alabama has the highest diversity of freshwater mussels with 178 species. To address the conservation needs of ...
Studies on the Epidemiology, Vaccination, Susceptibility, and Treatment of Columnaris Disease in Fishes
(2015-07-07)
In this dissertation, I explored the intraspecies genetic heterogeneity within Flavobacterium columnare isolates collected during particularly severe columnaris outbreaks observed at the E.W. Shell Fisheries Center, Aquatic ...
Studies on the Microbiota of Fishes and the Factors Influencing Their Composition
(2014-07-24)
In this dissertation, I aimed to characterize the microbiota of finfish including identification of the bacteria present as well as the factors that influence their composition. I examined the microbiota of the skin, gill, ...
Study and evaluation of bigano snail (Stramonita haemastoma) as a marketable seafood species
(2013-12-03)
To evaluate whether a species is potentially edible, marketable and sustainable, we need to answer quite a few questions about what, why, where, who, when and how. This dissertation consists of five chapters. The basic ...
Study of Bacterial Flora in Eastern Oyster (Crassostrea virginica) Treated with High Pressure
(2008-05-15)
Analysis of bacterial communities present in high-pressure treated, quick-frozen, and raw oysters was carried out independently during three different seasons: winter; summer; and fall of 2006. Oysters used in all experiments ...
