The physiological response of juvenile diploid and triploid Arctic charr Salvelinus alpinus to exhaustive exercise

open access: yesJournal of Fish Biology, EarlyView.
Abstract Triploidy is an effective tool for producing sterile fishes but often results in impaired performance in commercial aquaculture. In light of this, our study compared the physiological response to exhaustive exercise in juvenile diploid and triploid Arctic charr Salvelinus alpinus, a polar species with great potential for aquaculture.

Expression of corticoid‐regulatory genes in the gills of Atlantic salmon (Salmo salar) parr and smolt and during salinity acclimation

open access: yesJournal of Fish Biology, EarlyView.
Abstract In teleost fishes, cortisol is the major corticoid and has both glucocorticoid and mineralocorticoid actions. However, how fish tissues discriminate between these distinct corticosteroid actions is unclear. In mammals, the major factors responsible for intracellular corticosteroid regulation are glucocorticoid receptors (grs) and the ...

Genes, fish and fisheries: translating science into policy

open access: yesJournal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.

Study Regarding the Conformation in Four Populations of Reproduction - Female - Rainbow Trout (Oncorhynchus Mykiss) From Trout Farm Fiad, County of Bistrita-Nasaud

open access: yesScientific Papers Animal Science and Biotechnologies, 2023
Rainbow trout (Oncorhynchus mykiss) is the main specie exploited in the salmon complexes. The reason is the plasticity and resistance to changes in environmental and disease factors, and due to fast growth rate obtained by the processes of selection and ...
