Improving eel pass efficiency: The role of crest shape and water flow in facilitating upstream juvenile eel migration

Journal of Fish Biology, EarlyView.
Abstract River connectivity is crucial for the European eel (Anguilla anguilla) to complete its complex life cycle, which is vital for upstream recruitment to the declining population of this critically endangered catadromous fish. Eel passes, or ladders, are frequently installed on riverine structures, such as dams and weirs, to mitigate barrier ...

Effect of heterozygosity, ploidy and incubation temperature on post‐cranial axial skeletal meristics and deformities in Atlantic salmon (Salmo salar)

Journal of Fish Biology, EarlyView.
Abstract The teleostean post‐cranial axial skeleton is a highly specialized structure for an aquatic mode of life. However, there is limited knowledge regarding parental contributions, early‐life environmental impacts on its meristic variation and if reduced heterozygosity challenges its development.

Testing non‐lethal techniques for endoparasite detection and sex determination in pumpkinseed sunfish (Lepomis gibbosus)

Journal of Fish Biology, EarlyView.
Abstract Developing non‐lethal techniques to estimate parasite infection is critical for studying disease ecology in wild animals. We tested the effectiveness of coelomic ultrasonographic examination and plasma enzyme markers to detect liver infection with bass tapeworms Proteocephalus ambloplitis (Leidy 1887) as well as the effectiveness of ultrasound

Postprandial oxygen consumption, ammonia excretion and carbon dioxide production of channel and blue catfish

Journal of Fish Biology, EarlyView.
Abstract Fishes undergo dramatic physiological changes upon consumption of a meal, including an increase in oxygen consumption to support the metabolic cost of digestion [specific dynamic action (SDA)] and an increase in the excretion of ammonia. Channel catfish (Ictalurus punctatus) and blue catfish (I.

Insuring Uninsurable Risks from AI: The State as Insurer of Last Resort [PDF]

arXiv
Many experts believe that AI systems will sooner or later pose uninsurable risks, including existential risks. This creates an extreme judgment-proof problem: few if any parties can be held accountable ex post in the event of such a catastrophe. This paper proposes a novel solution: a government-provided, mandatory indemnification program for AI ...
