The Benefits Of Spirulina For Fish Growth, Health and Reproduction

Boost Fish Growth with Spirulina Fish Feed

Spirulina supplementation is an excellent replacement to existing protein diets given to fish. Increased growth, a strengthened immune system, and improved health due to antibacterial and antiviral activity are just a few of the positive effects of using spirulina as a fish feed.

Spirulina Fish Feed Supplements contain all the essential amino acids needed for fish growth and health, as well as other vitamins and minerals, commonly found in natural aquatic ecosystems.

Furthermore, thanks to its amazing ability to detoxify the body, Spirulina can cleanse heavy metals such as cadmium, lead, arsenic, and mercury out of the fish’s body, making it safer for human consumption.

Spirulina is Rich in proteins, lipids and essential fatty acids

Protein levels in aquaculture feeds generally average 18-20% for marine shrimp, 28-32% for catfish, 32-38% for tilapia, 38-42% for hybrid striped bass.
Average requirement is between 15-25% carbohydrates in fish diet
Mostly in the form of essential fatty acids, sometimes called vitamin F, which include linoleic, linolenic and arachidonic acids. Average fish requirement is around 17%.

The Main Benefits of Spirulina for Fish

  • Improves digestion and absorption of nutrients

  • Strengthens the fish immune system

  • Intensifies fish coloration with rich pigments

  • Reduces mortality and disease rates

  • Increases and uniforms fish growth rate

  • Aids in preventing swollen abdomen and blocked intestinal passages

  • Enhances unique enzyme production

Spirulina is rich in Bioavailable Pigments

Orange-yellow pigments cryptoxanthine and beta-carotene from which vitamin A is created. Intensifies fish color.
Blue pigment, important for healthy liver function and digestion of amino acids. Absorbs light and emits florescence.
Green pigment, improves oxygen levels in the pond thus helps to recover from excess nitrate and prevent nitrate poisoning.

Lipids & Essential Fatty Acids

In addition to its high content of quality protein, spirulina fish feed supplements provide lipids rich in ‘PUFAs’, or polyunsaturated omega-3 and omega-6 fatty acids. These are the ‘fish oil’ lipids that have become highly prized for their contribution to good cardiovascular health in humans. But it is not always appreciated that algae at the base of the aquatic food chain are in fact the origin of these ‘fish oil’ fatty acids. 

  • Isoleucine

    Required for optimal growth, nitrogen equilibrium in the body used to synthesize other non-essential amino acids. Increases muscular energy levels.

  • Lysine

    Building block of blood antibodies. Strengthens circulatory system and maintains normal growth of cells.

  • Methionine

    Vital lipotropic fat and lipid metabolizing amino acid that maintains liver health and acts as a stress reliever which soybean meal based diets lack.

  • Phenylalanine

    Stimulates metabolic rate.

  • Threonine

    Improves intestinal competence and digestive assimilation, regulates feed consumption and assists skeletal muscle growth

  • Tryptophane

    Increases the utilization of B vitamins and normalizes the synthesis of serotonin, nicotinic acid, hemoglobin and other compounds necessary for healthy body functions. Improving nerve health while helping to regulate endocrine status, reproductive functions and hematopoiesis.

  • Valine

    Stimulates muscle coordination and protein synthesis, naturally increasing fish growth rates.

The benefits of Spirulina for different fish species

  • Tilapia

    Protects from parasites and bacterial infections while enhancing cellular immune system function, coloration and appetite.

  • Salmon

    Enhances disease resistance while improving reproduction, appetite, skin quality and color.

  • Yellowtail Tune

    Increases growth rate and disease resistance and reduces mortality while enhancing fish coloration.

  • Ayu Sweetfish

    Improves the flavor, texture and color of meat while reducing disease.

  • Milkfish

    Improves growth a reproduction rate.

  • Fancy Koi Carp

    Enhances skin color and shine for a healthy appearance, improves disease resistance.

  • Queen Conch

    Improves juvenile growth and reduces the need for live algae

  • Prawns

    Eliminates the need for live algae. Increases immunity, stimulates growth and reproduction and enhances coloration.

  • Brine shrimp

    Replaces live algae for growth. Used as an enrichment before feeding to fish or prawns. Improves color.

  • Fish & Marine Larvae

    Increases appetite, and therefore contributes to better nutrition, faster growth rates and better survival rates.

  • Juvenile Fish

    Increases resistance to parasites, viral and bacterial diseases by enhancing cellular immune system function. Stimulates appetite and improves survival and appearance.
