Sensory characteristics of farmed and wild Atlantic salmon
The eating quality characteristics of farmed and wild Atlantic salmon, from locations in and around Northern Ireland, were compared by sensory analysis of frozen salmon. Quantitative descriptive analysis, using a trained panel, was used to compare specific attributes, while an untrained panel used hedonic scaling methods to assess acceptability. Freezing affected texture and appearance but had ...
متن کاملPopulation-specific gene expression responses to hybridization between farm and wild Atlantic salmon
Because of intrinsic differences in their genetic architectures, wild populations invaded by domesticated individuals could experience population-specific consequences following introgression by genetic material of domesticated origin. Expression levels of 16 000 transcripts were quantified by microarrays in liver tissue from farm, wild, and farm-wild backcross (i.e. F1 farm-wild hybrid × wild;...
متن کاملHybridization between escaped domestic and wild American mink (Neovison vison).
The release of domesticated organisms into natural populations may adversely affect these populations through predation, resource competition, and the introduction of disease. Additionally, the potential for hybridization between wild and domestic conspecifics is of great concern because it can alter the evolutionary integrity of the affected populations. Wild American mink (Neovison vison) pop...
متن کاملGenetic consequences of interbreeding between farmed and wild Atlantic salmon: insights from the transcriptome.
Large annual escapees of farmed Atlantic salmon enhance the risk of extinction of wild populations through genetic and ecological interactions. Recently, we documented evolutionary change in gene transcription between farmed and wild Atlantic salmon after only five generations of artificial selection. While differences for most quantitative traits are expected to gradually dilute through repeat...
متن کاملHybridization effects on phenotypic plasticity: experimental compensatory growth in farmed-wild Atlantic salmon
Compensatory growth (CG) is a means by which organisms can increase their growth rate above their routine growth rate after a period of environmentally induced growth depression. Despite a focus on the implications of CG for aquaculture, little research has evaluated the effect of domesticated-wild hybridization on CG. Any deviation in the mean compensatory ability of hybrids relative to their ...
