In the practical application of Haematococcus Pluvialis, the form of Natural Astaxanthin Powder is added to the feed as a feed additive for feeding. In aquaculture, astaxanthin is an essential nutrient for the normal growth of aquatic animals. This paper briefly introduces the application of astaxanthin and Haematococcus Pluvialis in aquafeed.
1. Impact on fish farming
1.1 Improve the growth and reproductive performance of fish
Adding Haematococcus Pluvialis to the feed can significantly improve the growth performance of farmed animals. At the same time, astaxanthin can also be used as a fertilization hormone to enhance egg quality. Adding an appropriate amount of astaxanthin to the feed can improve fish's egg buoyancy and survival rate. And the higher the amount of Haematococcus Pluvialis added, the better the effect on reproduction.
1.2 Promote the coloring of farmed fish
The rich color of fish is mainly the result of the action of carotenoids. However, because the fish body itself cannot synthesize related carotenoids, the change of body color can only be affected by exogenous pigments. Therefore, adding relevant additives to the feed can play a key role in regulating the body color of farmed fish. Especially for ornamental fish, the body color of ornamental fish is an important indicator to measure its commercial value. At present, the Natural Astaxanthin Powder in Haematococcus Pluvialis is the colorant with the best coloring effect on ornamental fish.
Adding Haematococcus Pluvialis to the feed can also promote bright red skin and muscles of fish, and the meat is more delicious, and the effect is more obvious than that of synthetic astaxanthin.
2. Impact on shrimp and crab farming
2.1 Improve the growth and reproductive performance of shrimps and crabs
Haematococcus Pluvialis, as a feed additive for shrimps and crabs, can improve the growth performance of shrimps and crabs, and promote the growth and reproduction of shrimps and crabs. The study found that adding Haematococcus Pluvialis extract in the feed can improve the weight gain rate, shelling rate and survival rate of juvenile crabs. At the same time, natural astaxanthin is more effective than synthetic astaxanthin in promoting the growth of juvenile shrimp.
2.2 Promote the coloring of shrimps and crabs
Astaxanthin plays an irreplaceable role in crustaceans. It can combine with proteins to form complexes, so that crustaceans show different colors. It is an important substance for the coloration of crustaceans. Added rain red to prawn feeding
The content of astaxanthin in shrimp shell and shrimp meat was significantly increased after feeding with cocaine, and increased with the increase of Haematococcus Pluvialis algal powder content, and the color of shrimp shell and shrimp meat were both improved. Significant improvement.
Summary
The physiological functions of Natural Astaxanthin Powder are potent. It has strong coloring and antioxidant functions, protecting cells from oxidative damage. Haematococcus Pluvialis is rich in natural astaxanthin. At the same time, the safety and uncertainty of synthetic astaxanthin need to be further confirmed. Therefore, it has a good prospect for the future development of aquaculture.
