Restoration of native Atlantic salmon runs in northern Spain: do costs outweigh benefits?

open access: yesKnowledge and Management of Aquatic Ecosystems, 2011
Atlantic salmon stocks in northern Spain are at the southern range of the species distribution. As such they are likely more vulnerable to environmental change and human disturbance. The Nalon-Narcea River salmon is one such population in Asturias, Spain.

Impacts of signal crayfish on stream fishes [PDF]

open access: yes, 2013
Invasive species cause biodiversity and economic loss globally. Invasive crayfish have a wide range of effects as a result of their high densities and biomass, feeding at multiple trophic levels, aggressive competition for shelter and ecosystem ...

Dietary methylmercury alters the proteome in Atlantic salmon (Salmo salar) kidney [PDF]

open access: yes, 2011
Background: Methylmercury (MeHg) is an environmental contaminant most known for its severe neurotoxic effects. Although accumulation of MeHg tends to be several folds higher in kidney compared to other tissues, studies on nephrotoxic effects are almost ...

Acute freshwater CO2 exposure does not impair seawater transfer in three different sizes of Atlantic salmon (Salmo salar) subjected to different photoperiod manipulations

open access: yesJournal of Fish Biology, EarlyView.
Abstract There is a growing interest in Atlantic salmon (Salmo salar) aquaculture to extend the time fish are reared in freshwater (FW) recirculating aquaculture systems (RAS), producing larger FW salmon that can then be induced to undergo smoltification before transfer into marine net pens for grow‐out and harvest.

A Novel Method for Rapid Screening of Salmonidae Ingredients and Accurate Detection of Atlantic Salmon (Salmo salar) Simultaneously Using Duplex Real-Time PCR Coupled with Melting Curve Analysis

open access: yesMolecules
The substitution of ingredients with Salmonidae, particularly Salmo salar, has led to widespread reports of financial losses and health risks globally, emphasizing the urgent need for the development of a rapid and precise method for species ...

Salmo salar and S. ferox in Tasmania [PDF]

open access: yesNature, 1885
IN your issue of October 29 is a communication from Mr. Saville Kent, in which he “concludes that no true salmon has yet been established in the lakes and rivers of Tasmania. The fish of large size which abound in the great lakes and other large sheets of water are really essentially the same as the great lake trout, Salmo ferox, of Great Britain.”

Transcriptomic profiling of gill biopsies to define predictive markers for seawater survival in farmed Atlantic salmon

open access: yesJournal of Fish Biology, EarlyView.
Abstract Wild Atlantic salmon migrate to sea following completion of a developmental process known as parr‐smolt transformation (PST), which establishes a seawater (SW) tolerant phenotype. Effective imitation of this aspect of anadromous life history is a crucial aspect of commercial salmon production, with current industry practice being marred by ...

Body size of male Atlantic salmon (Salmo salar L.) at introduction of a 5‐week LD12:12 winter signal influences their decision to mature early or smoltify

open access: yesJournal of Fish Biology, EarlyView.
Abstract Sexual maturation of male Atlantic salmon post‐smolts (‘jacking’) is undesired in aquaculture and seems to occur due to the intensification in modern facilities. Maturation depends on internal and external factors (temperature, photoperiod, feed availability, energy levels, body size, genetic background) that act on the brain‐pituitary‐gonad ...

Reproductive Cycle in Salmo Salar Linn [PDF]

open access: yesNature, 1939
IT is known that in Salmo salar Linn. there occurs regularly a very small percentage, possibly of the order of 0·1 per cent, of mature female fish in which discharge of ova may be delayed or does not take place. Such fish are found many months after the normal spawning time heavy with ripe ova. In certain parts of Scotland they are termed ‘baggots’ or ‘

Confidence in assessing the effectiveness of bath treatments for the control of sea lice on Norwegian salmon farms

open access: yes, 2012
The salmon louse Lepeophtheirus salmonis is the most important ectoparasite of farmed salmonids in the Northern hemisphere, having a major economic and ecological impact on the sustainability of this sector of the aquaculture industry. To a large extent,
