Spirulina - An Essential Feed Supplement in Aquaculture
Demand and awareness of the true potential properties of Spirulina in Aquaculture are rapidly growing. Spirulina is a blue-green algae, that grows both in fresh water and marine water. Aquatic organisms like fish, shrimp, prawn, etc., are hereditarily used for the consumption of algae as one of its essential food sources. Spirulina is packed with all essential nutrients and it is highly recommended in aquaculture for its Immunity boosting, mortality rate decreasing and weight gaining properties.
Neutralizes Toxic Minerals
Studies have shown that spirulina can detoxify toxic minerals like arsenic and heavy metals in food and water. This property of spirulina is an add-on value to the aquaculture industry. As it does not just provide nutrition to fish, shrimp and prawns but also helps in keeping the water in the cultivation pond toxin-free. Phycocyanin present in Spirulina is a rich source of biliverdin which is one of the most potent Intra-cellular antioxidants.
Research has proved that spirulina improves spawning, fecundity, fertility, and hatching rates. Spirulina Fed fish, shrimp, and prawns should increase energetic activity. Spirulina when fed continuously stimulates the reproductive process and promotes the appetite to attain full maturity.
Increases Survival rate, Growth rate, and Weight
Spirulina is made up of 60-70% of protein and it has a wide variety of essential amino acids like Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophane, Valine which are responsible for maintaining nitrogen equilibrium, providing essential antibodies, stimulating metabolic rate, to fish, shrimp, and prawn.
Batches of Fish, shrimp, and prawns that are well fed with spirulina show a decrease in mortality rate, a uniform, and fast growth rate, and increased weight up to 40% which makes the yield more profitable to the aqua framers.
Spirulina is rich in Anti-oxidants and it exhibits high anti-inflammatory and anti-viral properties. Spirulina is a great immune modulator. In open culture ponds, the are high possibility that fish, shrimp, and prawns can get infected by Allergens.
Spirulina inhibits the release of histamine from the mast cell preventing allergic reactions in the fish, shrimp, and prawns. Spirulina also increases the natural immune response that boosts the survival rate in these species.
Color Enhancing Properties
Spirulina is a rich source of Carotenoids, Carotenoids are naturally occurring pigments that are responsible for the coloration in shrimp, prawns, and fish (both edible and ornamental). Spirulina contains all-trans-β-carotene, all-trans-zeaxanthin, 9-cis-β-carotene, and diatoxanthin.
With the help of these carotenoids, Spirulina boosts physiological activities for generating color pigmentations and glazing appearance in various parts of the body. Color and appearance play a major role in creating market demand.
