Ontogenetic development of pallid sturgeon (Scaphirhynchus albus) and shovelnose sturgeon (Scaphirhynchus platorynchus) from hatch through yolk absorption

Sturgeons have a complex free-embryo period extending from hatch to the initiation of exogenous feeding. Although available for some sturgeon species of the genus Acipenser, descriptions of the developmental stages of free embryos of the genus Scaphirhynchus are lacking. We characterised the ontogenetic development of pallid sturgeon (Scaphirhynchus albus) and shovelnose sturgeon (S. platorynchus)

Probiotics beyond the farm: Benefits, costs, and considerations of using antibiotic alternatives in livestock

The increasing global expansion of antimicrobial resistant infections warrants the development of effective antibiotic alternative therapies, particularly for use in livestock production, an agricultural sector that is perceived to disproportionately contribute to the antimicrobial resistance (AMR) crisis by consuming nearly two-thirds of the global antibiotic supply. Probiotics and probiotic deri

Exposure to 17α-ethinylestradiol results in differential susceptibility of largemouth bass (Micropterus salmoides) to bacterial infection

Disease outbreaks, skin lesions, mortality events, and reproductive abnormalities have been observed in wild populations of centrarchids. The presence of estrogenic endocrine disrupting compounds (EEDCs) has been implicated as a potential causal factor for these effects. The effects of prior EEDC exposure on immune response were examined in juvenile largemouth bass (Micropterus salmoides) exposed

Use and Evaluation of Stimuli for Herding Bigheaded Carps to Increase their Capture Efficiency

Mass removal of the invasive silver carp Hypophthalmichthys molitrix and bighead carp Hypophthalmichthys nobilis (collectively referred to as bigheaded carp) is a primary management action in the United States to contain population growth and reduce upstream dispersal. Efficient capture and removal techniques are required to achieve this goal, and the USGS is working to develop and evaluate such...

Using Effects-Directed Analysis to test for Endocrine-Active Chemicals

Effects-directed analysis (EDA) reverse-engineers environmental toxicity testing by measuring effects on cells first, and identifying the particular chemicals later. In this publication, we reviewed published information on EDA methods to improve future methods.
