Evaluation of mitochondrial genomics in Salmo trutta caspius

Mitochondrial DNA. Part B. Resources, 2017
Salmo trutta caspius population is an important species for aquaculture and livestock industry. Moreover, these species are used for studies on molecular markers. Mitochondrial genomic is also beneficial for phylogenetic studies in salmonid species. They

Factors Influencing the Stocking of Juvenile Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Predator species of fish play crucial roles in ecosystem balance through top‐down control, a mechanism frequently exploited in biomanipulation to stock predator species. Juvenile pikeperch (Sander lucioperca) were stocked (n = 52,887) in spring 2023 and 2024 and autumn 2023 to compare stocking efficiency between Recirculation Aquaculture ...

Estrogen therapy offsets thermal impairment of vitellogenesis, but not zonagenesis, in maiden spawning female Atlantic salmon (Salmo salar) [PDF]

PeerJ, 2017
In female Atlantic salmon (Salmo salar), exposure to warm summer temperatures causes a reduction in plasma 17β-estradiol (E2), which impairs downstream vitellogenesis and zonagenesis, and reduces egg fertility and embryo survival.

Coping styles in farmed fish: consequences for aquaculture [PDF]

, 2017
Individual differences in physiological and behavioural responses to stressors are increasingly recognised as adaptive variation and thus raw material for evolution and fish farming improvements including selective breeding. Such individual variation has

Effects of the Invasive Round Goby on Swedish Recreational Fishing Values

Fisheries Management and Ecology, EarlyView.
ABSTRACT The round goby, an invasive fish from the Black and Caspian Seas, has spread to Swedish waters, threatening recreational fisheries. We modeled impacts on the future recreational fishery in Sweden using data from a recreational fishing survey, and estimated effects of the round goby on other fish species. Values attached to recreational fishing

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

Knowledge 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.

The use of prevalence as a measure of lice burden: a case study of Lepeophtheirus salmonis on Scottish Atlantic salmon, Salmo salar L., farms [PDF]

, 2009
This study investigates the benefits of using prevalence as a summary measure of sea lice infestation on farmed Atlantic salmon, Salmo salar L. Aspects such as sampling effort, the relationship between abundance and prevalence arising from the negative ...

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

Journal 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

Molecules
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 ...

Assessing risks of invasion through gamete performance: farm Atlantic salmon sperm and eggs show equivalence in function, fertility, compatibility and competitiveness to wild Atlantic salmon [PDF]

, 2014
Adaptations at the gamete level (a) evolve quickly, (b) appear sensitive to inbreeding and outbreeding and (c) have important influences on potential to reproduce.
