(2018-11-07)
Channel catfish (Ictalurus punctatus) is one of the most abundant catfish species in North America. The objectives of this study were to determine the effectiveness of the Masou salmon delta5-desaturase transgene driven ...
Taxonomy and phylogenetics of fish blood flukes using morphology, life history, and molecular markers
(2016-08-05)
Fish blood flukes (Digenea: Aporocotylidae) are of rapidly progressing and emerging interest to ecology and evolutionary biologists because some lineages may have coevolved with the major lineages of non-tetrapod vertebrates ...
Taxonomy and Systematics of Early Lineage Fish Blood Flukes (Digenea: Aporocotylidae)
(2019-07-15)
The monophyletic fish blood flukes (Platyhelminthes: Digenea: Aporocotylidae Odhner, 1912) comprise ~166 species assigned to 40 genera infecting freshwater, marine, and estuarine fishes. They are occasional pathogens of ...
Taxonomy and systematics of freshwater turtle blood flukes (Digenea: Schistosomatoidea)
(2017-07-26)
Blood flukes (Platyhelminthes: Trematoda: Digenea: Schistosomatoidea) currently comprise three families: Schistosomatidae Stiles and Hassall, 1898 (species infecting mammals and birds and one crocodilian), Aporocotylidae ...
Taxonomy and Systematics of Myxozoans (Cnidaria: Myxozoa) and Disease Epidemiology of Myxobolus cerebralis in the Southeast United States
(2020-04-17)
Myxozoa (Cnidaria) comprises over 2500 species of parasitic cnidarians infecting primarily
freshwater, marine, and estuarine fishes. They represent some of the most demonstrable
pathogens to cultured fishes including: ...
Taxonomy, systematics, and life cycles of Azygiids (Digenea: Azygiidae) of the Southeastern United States
(2015-12-08)
Digeneans (Platyhelminthes: Trematoda: Digenea) comprise the vast majority of Trematoda, which is one of three entirely parasitic classes within the Platyhelminthes. They are characterized as having complex life cycles ...
Technical and Educational Aspects of Stream Biomonitoring Protocols for Teachers and Citizen Monitors in Alabama
(2007-12-15)
Accuracy of the Alabama Water Watch (AWW) Stream Biomonitoring Protocol for citizen monitors was assessed through a desktop study comparing simulated AWW stream quality assessments to known professional bioassessments. ...
Terrestrial adaptation: Expansion of myoglobin and up-regulation of hemoglobin genes in the walking catfish (Clarias batrachus)
(2017-07-07)
Walking catfish (Clarias batrachus), a freshwater fish capable of locomotion on land, serves as a great model for understanding adaptations to terrestrial life. Through comparative genome analysis, here I report that no ...
Test of the effects of geography, gear type, and culture techniques on Vibrio risks associated with farm-raised oysters
(2020-11-16)
During the off-bottom aquaculture growing process for the eastern oyster, Crassostrea virginica, farmers routinely remove the oysters for tumbling and desiccation. These routine handling practices improve oyster quality ...
Total sulfur amino acid requirement and its application to practical diets for juvenile tilapia (Oreochromis spp.)
(2007-08-15)
Tilapia have become one of the most important fish species for aquaculture and play an increasing role in the international aquatic food trade. Therefore, the development of cost-effective feeds using inexpensive and locally ...
Towards the identification of sex-determining gene(s) in channel catfish
(2013-06-20)
Sex is the most fundamental feature in the life of an organism. Studying of sex determination is an important area in animal developmental and evolutionary biology, as well as ecology. In teleost, sex determination mechanism ...
Toxic Cyanobacteria and Plant Defenses Against a Generalist Herbivore
(2011-07-18)
Toxin-producing cyanobacteria have frequently been hypothesized to limit the ability of herbivorous zooplankton (such as Daphnia) to control phytoplankton biomass by inhibiting Daphnia feeding, population growth, and in ...
Transcriptomic profiling of differential responses to drought in two freshwater mussel species, the giant floater Pyganodon grandis and the pondhorn Uniomerus tetralasmus
(2013-11-08)
The southeastern US has experienced recurrent drought during recent decades. Increasing demand for water, as precipitation decreases, exacerbates stress on the aquatic biota of the Southeast: a global hotspot for freshwater ...
Transgene Insertion of Cathelicidin Gene in Channel Catfish Ictalurus punctatus using CRISPR/Cas9 Knock-in Technology and Cathelicidin Activity Against Catfish Pathogens
(2020-04-22)
