Variation in food availability affects the population age structure of Atlantic puffins Fratercula arctica in the Faroe Islands

open access: yesWildlife Biology, EarlyView.
Across their entire Atlantic breeding range, Atlantic puffins Fratercula arctica have experienced decreases in food availability, often leading to population declines. The species is one of the most numerous seabirds in Føroyar (the Faroe Islands, in English) but has faced apparent, unquantified population declines.

Evaluating genetic traceability methods for captive bred marine fish and their applications in fisheries management and wildlife forensics [PDF]

open access: yes, 2014
Growing demands for marine fish products is leading to increased pressure on already depleted wild populations and a rise in the aquaculture production.

Causal Models as a Scientific Framework for Next‐Generation Ecosystem and Climate‐Linked Stock Assessments

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Rapid changes in marine ecosystems highlight the need to account for time‐varying productivity in stock assessments used to support fisheries management. Common approaches incorporate annual variation or regressing processes such as recruitment, natural mortality, or growth on environmental variables.

Implications of fisheries during the spawning season for the sustainable management and recovery of depleted fish stocks: a conceptual framework [PDF]

open access: yes, 2009
Fishing during the spawning season may negatively affects the reproductive potential and reproductive dynamics of exploited fish stocks due to a variety of mechanisms such as the disturbance of the natural spawning behaviour, effects on the age, size and

Nodavirus in farmed Atlantic cod Gadus morhua in Norway [PDF]

open access: yesDiseases of Aquatic Organisms, 2007
Viral encephalopathy and retinopathy (VER) was diagnosed in 5 to 24 g sized farmed Atlantic cod Gadus morhua kept in sea cages at Parisvatn, Hordaland county, on the west coast of Norway. Moderate mortality (10 to 15%) was observed, along with anorexia and abnormal swimming behaviour, such as looping or spiral swimming and reduced coordination ...

Effects of the Invasive Round Goby on Swedish Recreational Fishing Values

open access: yesFisheries 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

Integrative omics-analysis of lipid metabolism regulation by peroxisome proliferator-activated receptor a and b agonists in male Atlantic cod

open access: yesFrontiers in Physiology, 2023
Lipid metabolism is essential in maintaining energy homeostasis in multicellular organisms. In vertebrates, the peroxisome proliferator-activated receptors (PPARs, NR1C) regulate the expression of many genes involved in these processes.

Influence of chilled and frozen storage on the stability of trout and herring fillet [PDF]

open access: yes, 2006
Effects of chilled and frozen storage on specific enthalpy (ΔH) and transition temperature (Td) of protein denaturation as well as on selected functional properties of muscle tissue of rainbow trout and herring were investigated. The Td of myosin shifted

Post‐Release Mortality of European Bass (Dicentrarchus labrax) Discarded From Small‐Scale Estuarine Fishing

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Estuaries provide essential habitats for many fish species, but their confined and accessible nature may increase fish vulnerability to capture, and few empirical studies have quantified the value of restricting net fisheries in such areas.

Rapid morphological divergence of cultured cod of the northwest Atlantic from their source population

open access: yesAquaculture Environment Interactions, 2015
The performance of aquaculture escapees in the wild depends in part on how their morphology differs from that of wild fish. We compared farmed Atlantic cod Gadus morhua morphology to that of wild cod from the same ancestral population.
