Science of Superior Nutrition

What's Inside
Makes the Difference

Premium nutrition is not a marketing claim — it is a measurable science. Explore the key ingredients, their roles, and why they matter for koi and arowana.

Every gram in the bag is a deliberate choice

JPD formulations are developed in collaboration with Mie University and verified under GMP-certified production standards. The result: feeds engineered to unlock the full genetic potential of your fish — whether you're growing show koi or keeping arowana as living art.

Koi Nutrition

Key Ingredients Explained

A visual breakdown of what goes into a premium koi pellet and the role each ingredient plays.

Energy

Wheat Germ

Easily digestible energy source

Cold-water digestible carbohydrate that fuels koi even at low temperatures (below 15°C), ideal for spring & autumn feeding.

Colour

Spirulina

Natural colour intensifier

Rich in phycocyanin and carotenoids, spirulina amplifies red, orange and yellow pigmentation without artificial dyes.

Protein

Fish Meal (Premium)

High-quality animal protein

White fish meal provides a complete amino acid profile essential for muscle development, tissue repair and healthy growth.

Immunity

Vitamin C & E Complex

Antioxidant & immune support

Stabilised ascorbic acid and tocopherols protect cells from oxidative stress, boost immune response and speed wound healing.

Colour+

Astaxanthin

Superior red pigment enhancer

The most potent carotenoid pigment — 10× stronger than beta-carotene — used by champion breeders to deepen beni (red) patterns.

Growth

Crude Protein (≥38%)

Growth & body conformation

A high protein ratio drives rapid, balanced growth in young koi while maintaining the body depth prized in Jumbo Tosai.

Vitality

Omega-3 Fatty Acids

Vitality & skin lustre

EPA and DHA sourced from marine oils support cell membrane integrity, brain function and the bright, lustrous skin finish.

Digestion

Probiotics & Enzymes

Digestive efficiency

Bacillus subtilis and digestive enzymes improve nutrient absorption, reduce ammonia excretion and support gut microbiome balance.

Why it matters

Premium vs Standard — The Numbers

The gap between a standard feed and a JPD premium formula is not marginal. Across every key metric — protein quality, colour compounds, digestibility and immune support — premium nutrition delivers results that are measurably superior.

Arowana Nutrition

Formulated for the Dragon Fish

Arowana are obligate carnivores with very different nutritional demands. Premium arowana feeds account for their unique biology.

🦴

Bone & Scale Development

Precise calcium-to-phosphorus ratios ensure proper scale mineralisation and a strong skeletal frame — essential for large predatory fish.

Metallic Sheen Enhancement

Chelated trace minerals (zinc, copper, manganese) activate melanin and iridophore cells that produce the legendary golden and silver sheen of arowana.

💪

High-Protein Carnivore Formula

45–50% crude protein mimics natural prey, supporting the explosive muscle growth and predatory health of Super Red, Golden and Silver arowana.

🛡️

Immune & Stress Resilience

Stabilised vitamin C, beta-glucans and organic selenium reduce susceptibility to disease and build long-term resilience in captive environments.
