FISHING GROUNDS
Our fishing grounds: from Townsville to Tasmania's pristine waters.
Our fishing grounds extend across the Pacific Ocean, from the warm, tropical waters off Townsville to the nutrient-rich, cooler currents near Tasmania. This range allows us to target the finest wild-caught species by carefully considering seasonality, water temperature, and migratory patterns. Using precision and sustainable methods, we minimise environmental impact and support marine biodiversity, ensuring the long-term health of these waters while delivering premium-quality seafood.
Key factors for sustainable success.
Our commitment to environmental stewardship is evident in every aspect of our operation, from using insulated steel vessels to implementing cutting-edge refrigeration and chilling techniques. We work hard to sustain the oceans that provide for us.
Strategic regional targeting of migrating wild catches.
We strategically adjust our fishing locations along the Australian East Coast, shifting between Townsville, Sydney, and Tasmania based on fish population dynamics and seasonal variations. This approach ensures a consistent and high-quality supply throughout the year.
Precision monitoring of water temperatures for sustainable fishing.
Our Fishing Master uses innovative technology to set lines at the perfect water column depth, targeting optimal temperatures that yield the best quality fish. This precision minimises by-catch and supports the ecosystem's balance.
Adapting seasonal and lunar fishing strategies for optimal results.
We account for moon phases and natural fish behaviours, adjusting our longline methods to maximise yield and quality. By respecting these cycles, we achieve a sustainable harvest and reduce environmental impact.
Local partnerships and efficient short trips for fresher seafood.
We collaborate with local ports for efficient unloading, allowing for shorter, more frequent fishing trips. This method enhances the freshness of our catch and reduces time to market, benefiting both our clients and the environment.
