Salmon farming

The study by Hites et al. (2004) of BDEs in farmed and wild salmon promoted discussions regarding the consumption of fatty fish. The health benefits of omega-3 fatty acids are clear, but the consumption of (especially) farmed fish exposes consumers to higher intakes of lipophilic contaminants (including BDEs) and so presumably to an additional health risk (Law et al, 2006a). The development of less contaminated feeds for use in salmon farms may be a way of reducing this risk. 

As the world s fisheries have declined, attention has turned to aquaculture. For it to be sustainable in the future, current problems of replacement of mangroves by ponds, use of wild fish as feed, pollution from wastes, escapes of exotic species or varieties, and the short lifetimes of ponds, must be solved.87 Shrimp and salmon farming have many of these problems. It would be better to farm herbivorous fish. 

Fatty Acids Omega-3 and omega-6 fatty acids are fatty acids that get their names from their structures. They contain a double bond either three or six carbon atoms from the end of the fatty acid chain. These fatty acids have a beneficial effect on health because they lower bad cholesterol levels and raise good cholesterol levels in the blood. Levels of omega-3 and omega-6 fatty acids were studied in salmon from three different sources as well as in the feed used in salmon farming.

Salmon farm Wild salmon contains predominantly the (3S,3 S)-enantiomer. In fanned salmon, fed with shrimp bran, which is mainly produced from northern prawn (Pandalus borealis) or with an extract from the green alga Haematococcus pluvialis, the (3S,3 S)-enantiomer is also the main enantiomer. However, if the astaxanthin comes from the basidiomycetous yeast Phaffia rhodozyma or its sexual form Xanthophyllomyces dendrorhous, or from the Antarctic krill (Euphausia superba), the (3R,3 R)-enantiomerprevails.

Cordage is also used in rigid stractures. Lobster pots (Fig. 13.20 (a)) are a solid frame covered with net. In aquaculture, fish are contained by netting attached to metal or plastic frames, either in small cages for hatching (Fig. 13.20 (b)) or in large salmon farms (Fig. 13.20 (c)).
