Step 1: Geothermal Sourcing

We harness the ancient power of the earth, drawing geothermal heat from deep within the volcanic bedrock of Rotorua. This sustainable energy source ensures optimal water temperatures for our aquaculture systems year-round, minimizing our carbon footprint and creating the perfect environment for healthy, thriving fish. Our methods prioritize ecological balance, ensuring the geothermal resource remains pristine for generations.

Step 2: Volcanic Ash Filtration

Purity is paramount. Our proprietary multi-stage filtration system utilizes local volcanic ash, renowned for its incredible porousness and mineral composition. This natural filter meticulously purifies our water, removing impurities and enriching it with beneficial minerals, creating an aquatic environment that mimics the clearest natural springs. This unique process results in fish with unparalleled taste and quality.

Step 3: Low-Impact Farming

Our commitment to sustainability extends to our farming practices. We maintain low-density fish populations in spacious, clean environments, reducing stress and promoting natural growth. We utilize only sustainably sourced, high-quality feed, free from hormones and unnecessary additives. Advanced waste management and recirculating aquaculture systems ensure minimal environmental impact and conserve precious water resources.
