Trials conducted on Salmonids in the
U.K., Chile, Norway and the US have established the efficacy of
NatuRoseTM natural astaxanthin as an effective carotenoid and
vitamin source for farmed-raised salmonids. (Norway has been
the leading producer of farmed salmon for decades.) The
continuous growth of salmonid farming has created an enormous
demand for pigments. The flesh colour of salmonids is due to
the absorption and deposition of dietary oxygenated
carotenoids, primarily astaxanthin.
Salmonids are unable to synthesize
astaxanthin de novo, thus carotenoid pigments must be supplied
in their artificial aquaculture diet. Astaxanthin is
accumulated in the diet through insects or crustaceans which
are ingested by salmonids. Since cold water fish like salmonids
have a high level of polyunsaturated fats in their membranes,
astaxanthin can effectively protect lipid tissues from
Benefits of NatuRose
- Farm trials with NatuRose produced salmon with equal or
better color scores than synthetic pigments.
- Atlantic salmon fed with NatuRose had even more natural
- NatuRose is oil-miscible and ideal for topcoat or
vacuum infusion applications.
- NatuRose's esterified form provides greater stability
than synthetic and other natural sources.
- Recommended use in accordance with Good Manufacturing
Practices (GMP) at levels that will enhance the
pinkish orange colour of salmonid flesh to an acceptable
