Effects of Increased Water Salinity and Temperature on the Development of Rainbow Trout Fry Syndrome (RTFS) Caused by Flavobacterium psychrophilum

open access: yesJournal of Fish Diseases, EarlyView.
ABSTRACT Flavobacterium psychrophilum, the etiological agent of Rainbow Trout Fry Syndrome (RTFS) and Bacterial Coldwater Disease (BCWD), causes varying degrees of disease and mortality in salmonid aquaculture worldwide. Because its treatment relies on the use of antimicrobials, alternative interventions are of environmental and economic interest.

Effects of introduced trout predation on non-diadromous galaxiid fish populations across invaded riverscapes [PDF]

open access: yes
We assessed the landscape-scale effect of predation pressure from trout on the population integrity and distributions of non-diadromous galaxiids in high-country streams of the South Island, New Zealand.

Contribution of Amino Acids in Cereal Grain Products to Precision Feed Formulation for Tambaqui (Colossoma macropomum) Using a Digestibility Approach

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Although cereal grain products have low protein content, they can contribute up to 25% of total protein in low‐trophic level/omnivorous fish diets. Thus, understanding the amino acid contribution of these ingredients becomes crucial for meeting the dietary requirements of omnivorous fish.

The Genomics Revolution in Nonmodel Species: Predictions vs. Reality for Salmonids

open access: yesMolecular Ecology, EarlyView.
ABSTRACT The increasing feasibility of whole‐genome sequencing has been highly anticipated, promising to transform our understanding of the biology of nonmodel species. Notably, dramatic cost reductions beginning around 2007 with the advent of high‐throughput sequencing inspired publications heralding the ‘genomics revolution’, with predictions about ...

Putting Structural Variants Into Practice: The Role of Chromosomal Inversions in the Management of Marine Environments

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Major threats to marine species and ecosystems include overfishing, invasive species, pollution and climate change. The changing climate not only imposes direct threats through the impacts of severe marine heatwaves, cyclones and ocean acidification but also complicates fisheries and invasive species management by driving species range shifts.

Recent Adaptation in a Threatened Salmonid Revealed by Museum Genomics

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Steelhead/rainbow trout (Oncorhynchus mykiss) is an imperilled salmonid with two main life history strategies: migrate to the ocean or remain in freshwater. Domesticated hatchery forms of this species have been stocked into almost all California waterways, possibly resulting in introgression into natural populations and altered population ...

Bdh1l Gene Expression Is a Potential Molecular Factor in the Evolution of Carotenoid‐Based Colour Diversity of Cichlid Fishes

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Carotenoids contribute substantially to animal body colour pattern diversity. While the ecological and evolutionary drivers of carotenoid coloration are reasonably well understood, the molecular mechanisms facilitating evolutionary transitions between red and yellow hues are less investigated.
