Vitamin C is essential nutrient found in foods. It performs specific and vital functions in a variety of body systems and these are crucial for maintaining optimal health and essential for the growth and maintenance of aquatic animal life. This Vital Vitamin is not synthesized by the fish body or at a rate sufficient to meet the aquatic animals needs. They are required by the fish body in trace amounts. All fish/shrimp display distinct morphological and physiological deficiency signs when Vitamni C is absent from the diet.


Karyocee probably is the most important because Vitamin C a powerful antioxidant and immunomodulator for fishes/ shrimps. The fish and shrimp body needs vitamin C ( ascorbic acid or ascorbate) to remain in proper health condition.

Karyocee makes various benefits to the fish/ shrimp body by holding cells together through collagen synthesis. Collagen is a connective tissue that holds muscles, bones, and other tissues together. Collagen is also needed for the healing of wounds.

Vitamin C also requires in wound healing, bone and tooth formation, strengthening blood vessel walls, improving immune system function, increasing absorption and utilization of iron, and acting as an antioxidant.

Vitamin C works with vitamin E as an antioxidant and plays a crucial role in neutralizing free radicals throughout the body.

Karyocee reduces the effects of toxic chemicals in water and prevent negative effects of water temperature fluctuations.

Karyocee increases intestinal absorption of iron from plant-based foods.

Karyocee enhances in immune response.

Karyocee helps synthesize carnitine, adrenaline, epinephrine, the neurotransmitter serotonin, the thyroid hormone thyroxine, bile acids, and steroid hormones.

Karyocee regulates the moult phase and helps in quick formation of exoskeleton in shrimps.

Major Functions of Karyocee

Water temperature: Karyocee diets helps to fishes during low temperature period for enhancing digestion efficiency and thereafter promote growth rate.

Stress: The ascorbic acid concentrations in tissues in fish change during stressful periods Karyocee prevents from various stress such as: environmental stress, handling stress, pathogenic stress, transportation stress, osmotic stress etc, of fishes and shrimps.

Toxic Gasses Eliminator: Karyocee helps to eliminate the adverse effect of ammonia on growth of fishes and reduces the toxic effect of nitrite levels in intensive aquaculture systems.

Wound healing: Karyocee makes collagen formation in body and helps in quick for optimal wound repair in fishes and shrimps.

Reproduction: Karyocee helps in reproduction systems of fishes and shrimps such as growth of healthy brooders, proper egg and sperm formation, optimum fecundity, improve hatchability, healthy larval and fry conditions etc.

Larval Nutrition: Diet with Karyocee acts fast development of embryo /larvae and early fry stages with reduction of mortality in early stages of fishes /shrimps.

Immunity: Vitamin C is at the top of the list among natural immune boosters for fish /shrimp body. Karyocee have the immune-stimulating properties and compensate the immune-depression. It offers protection to fish / shrimp immune system by encouraging the activity of immune system cells including neutrophils and phagocytes. The collagen prevents various diseases caused by bacteria and viruses . Mucus helps in preventing microorganisms from entering to the body through the skin, gills and gastrointestinal mucosa. Vitamin C prevents bacteria from adhering to epithelial cells. High concentration of vitamin C in white blood cells enables the immune system to function properly by providing protection against oxidative damage from free radicals generated during their action against bacterial, viral, or fungal infections.

Antioxidant: Free radicals, such as superoxide, hydroxyl ions and nitric oxide all contain an unpaired electron. These radicals can have a negative effect on cells causing oxidative damage that leads to cell death. Antioxidants, such as vitamin E & Vitamin C, prevent cell damage by binding to the free radical and neutralising its unpaired electron. Ascorbic acid is well known for its antioxidant activities. Ascorbate acts as a reducing agent to reverse oxidation in aqueous solution.

Composition: Ascorbyl Polyphospahte (Dry phosphorylated form).


  • Provide Stable and bio-available vitamin C.
  • Improve Survival rate.
  • Accelerates growth.
  • Improves feed conversion ratio (FCR).
  • Increases body weight.
  • Helps in skeleton formation through the absorption and utilisation of calcium by gills, bones, muscles and skin,the major sites of Ca uptake and storage.
  • Facilitates tissue repair and would healing-supplementation of higher than normal level of vitamin C increases resistance to infection and fast wound healing.
  • Strengthens host defence mechanism by increasing resistance to Stress, High mortality & Disease.
