Farmed salmon feeds have changed from purely marine-based diets with high levels of EPA and DHA in the 1990s to current 70 % plant-based low these fatty acids (FA). The aim this study was establish impacts dietary on performance tissue integrity Atlantic (Salmo salar). (50 g) seawater were fed fourteen experimental diets, containing five (0, 0·5, 1·0, 1·5 2·0 %) EPA, or a 1:1 EPA+DHA plus control close commercial diet, final weight 400 g. Lack did not influence mortality, but n-3-deficient...
Abstract In the recent years, challenges faced in salmonid farming with regard to deformities have helped improve our knowledge on skeletal biology and development of bone health salmonids. Different nutritional, genetic environmental factors are associated salmonids other fish species. Minerals a group essential nutrients having vital role play development, growth remodelling. The generated thus far structural functional importance minerals is largely restricted phosphorus. A brief account...
The suitability of land animal by-products (ABPs) in feed for Atlantic salmon postsmolts (initial weight 372 g) sea water was studied a feeding experiment, using poultry by-product meal (PBM) and porcine blood (BM) as protein sources oil fat source. Four extruded feeds were tested 2 * factorial model, with or without ABP oil. control contained mix marine plant ingredients. Initial intake highest the protein-based diets, whereas had weak opposite effect. No differences seen growth rate body...
The effects of replacing dietary fish meal (FM) and oil (FO) with plant ingredients on absorption, metabolism, flesh retention astaxanthin were tested in Atlantic salmon. Phospholipid (PL) concentrates marine (MPL) or origin (Soy lecithin, SoyLec) supplemented to plant-based diets as choline sources study potential absorption retention. A total six tested, three them at high low temperature (6 12°C). Lower slower growth increased the muscle marine-diet group but had no effect groups....
A method for measurement of gastrointestinal passage rate was tried in Atlantic salmon, Salmo salar (body weight 1131 g, temperature 13.5 °C, salinity 32‰). Salmon were force fed one single ration (10 g) extruded feed ‘as is’ (92% dry matter) or soaked 2 h sea water (70% matter), triplicate with three individuals per replicate. Content from stomach, small intestine and distal collected at 2, 6, 12, 18, 24 48 after feeding. Two hours feeding, significantly more transferred the stomach to...
Abstract There is an urgent need to find alternative feed resources that can further substitute fishmeal in Atlantic salmon diets without compromising health and food quality, particular during the finishing feeding period when demand highest flesh quality effects are most significant. This study investigates efficacy of substituting a isoprotein (35 %) isolipid low diet (FM, 15 with Antarctic krill meal (KM, 12 3 months growing 2·3 kg (quadruplicate sea cages/diet). Final body weight (3·9 (...
A strain of Yarrowia lipolytica engineered to produce high levels eicosapentaenoic acid (EPA) was used as feed ingredient Atlantic salmon (Salmo salar L.). The study designed investigate the effect washing and cell disruption, on growth, bioavailability, fillet composition growing from 0.5 1 kg. Four diets containing 200 g kg-1 yeast (Unwashed/Not disrupted, Unwashed/Disrupted, Washed/Undisrupted, Washed/Disrupted) were compared a fishmeal-based control diet in 112-day feeding experiment....
The relationships between fillet colour (CIE L* a* b* and CIE C* H°ab) carotenoid concentration were investigated using samples taken from Arctic charr, Salvelinus alpinus (L.), of different ages sizes, which held under a variety rearing conditions. Relationships parameters concentrations nonlinear. Increasing led to increased redness (a*), yellowness (b*) chroma (C*), decreased lightness (L*) hue angle (H°ab). Redness was the parameter most highly correlated with charr fillets. For given...
Two trials with Atlantic salmon (Salmo salar) were conducted to evaluate the potential of krill meal improve feed intake. In first experiment, after transfer sea water, smolts fed diets added 75 or 150 g kg−1 Antarctic in substitution for fish 13 weeks. The apparent digestibility coefficient crude protein and majority amino acids was significantly lower feeds (around 83.5%) than control diet (84.9%), whereas lipids, dry matter energy not different among three diets. Krill addition resulted...
New sources of the very long-chain n-3 polyunsaturated fatty acids (n-3 VLC-PUFA) are needed for sustainable growth salmon farming. In recent research high VLC-PUFA canola oil has shown promise as a safe and effective source docosahexaenoic acid (DHA) other PUFA in small Atlantic salmon. To study its long-term effects on performance fillet quality under realistic farming conditions, 12-month feeding experiment was carried out with growing to harvest weight (4.7 kg) triplicate sea water...
Raman spectroscopy (785 nm excitation) was used to determine the overall carotenoid (astaxanthin and cantaxanthin) fat content in 49 samples of ground muscle tissue from farmed Atlantic salmon ( Salmo salar L.). Chemically determined contents ranged 1.0 6.8 mg/kg carotenoids 36 205 g/kg fat. In addition raw spectra, three types spectral preprocessing were evaluated: first derivative, subtraction fitted fourth-order polynomial (POLY), intensity normalized versions POLY (POLY-SNV).
