Do trophic subsidies affect the outcome of introductions of a non-native freshwater fish? [PDF]
, 2013 Understanding how environmental variables and human disturbances influence the outcomes of introductions of non-native freshwater fish is integral to their risk management. This can be complex in freshwater ecosystems that receive subsidies that increase

Anadromous fish as marine nutrient vectors [PDF]
, 2009 The tidal freshwater of Virginia supports anadromous herring (Alosa spp.) spawning runs in the spring; however, their importance as nutrient delivery vectors to the freshwater fish food web remains unknown.

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Blindness in Freshwater Fishes [PDF]
Nature, 1938 THE cause of blindness in some rainbow trout was recently described by me1 as being due to a trematode, Diplostomum volvens Nord., being present in large numbers in the lens of the eye. Since that date, two more lots of rainbow trout and one lot of roach have been examined, and in each case about five per cent of the fish were blind, due to a similar ...

Designing of Self‐Dispersing Soft Dendritic Microcleaners for Microplastics Capture and Recovery
Advanced Functional Materials, EarlyView.The capture and recovery of microplastics from open aquatic systems is a complex problem, which necessitates nontrivial solutions. The principles of a comprehensive multistage process based on sustainably sourced microcleaners with hierarchical morphology are demonstrated.

Probiotics for cultured freshwater fish [PDF]
Microbiology Australia, 2020 Probiotic products are viewed as an alternative to the use of antibiotics in freshwater fishes farming. Probiotic organisms include bacteria, yeast, and filamentous fungi offering different benefits to fish including growth promotion, inhibition of pathogen colonisation, and improvement of nutrient digestion, water quality, and stress tolerance, as ...
