Our Sustainable Story

SeaDragon formally reviewed its unrefined oil sourcing arrangements to assess the oversight and management of the fisheries.


SeaDragon’s vision is to be recognised as a world-class provider of marine ingredients which are sustainably sourced from the Southern Oceans and manufactured in New Zealand. We have integrated sustainability into our vision because careful management of marine resources is integral to the viability of our industry for the long term.

SeaDragon currently produces refined Omega-3 products from unrefined tuna oil sourced primarily from skipjack, albacore and yellowfin tuna caught in the South Pacific and skipjack and albacore tuna caught in the Indian Ocean.

We also source oil from New Zealand waters primarily from the hoki fisheries and we expect this resource
to represent a growing share of the oil we source and refine.

In the last year, SeaDragon formally reviewed its unrefined oil sourcing arrangements to assess the oversight and management of these fisheries, the state of the fish stocks and their ability to sustain the current level of fishing.

The review, which considered the management of the fisheries and independent assessments on their health, has confirmed the strength of our responsible sourcing processes and further reinforced our confidence that SeaDragon’s practices are aligned with building a sustainable business for the long-term.


Research commissioned by the Western and Central Pacific Fisheries Commission (WCPFC) and the Indian Ocean Tuna Commission (IOTC) have found the fisheries from which SeaDragon sources unrefined fish oil are healthy and more than capable of supporting the current level of fishing. Data comparison between the two regions is difficult due to different scientific approaches.

The International Seafood Sustainability Foundation (ISSF), a global organisation formed in 2009 as a non-profit partnership among the tuna industry, scientists and the World Wide Fund for Nature, is one of the many non-governmental organisations that review the WCPFC and IOTC data and research.

In the ISSF’s most recent report assessing tuna stocks across different regions it used a consistent methodology allowing an easy comparison between regions. The ISSF validated
the findings of the WCPFC and IOTC science and it made the following assessments of the stocks from which SeaDragon sources its oil.

In the Indian Ocean SeaDragon sources unrefined tuna oil from members of the IOTC. It is charged with the management of tuna stocks in the region to ensure the optimum use and the sustainable development of the region’s tuna fisheries. The IOTC’s 32 members states, and the fishing vessels operating out of those states, must comply with the IOTC’s conservation and management measures. The IOTC operates a monitoring and surveillance programme to ensure compliance.


SeaDragon sources unrefined oil from countries in the Pacific that are members of the WCPFC one of a global network of fishery management organisations. Fishing entities operating out of the 27 WCPFC member countries are bound to the rules of the WCPFC. The commission has established monitoring, control and surveillance programmes to ensure compliance with the rules.

SeaDragon sources hoki and a mix of other species caught within the New Zealand exclusive economic zone and managed under the New Zealand Quota Management System, which has its focus on the sustainable management of fish stocks.

The system is managed by the New Zealand government (MPI), which sets a yearly catch limit (the total allowable catch) for every fish stock. The quota is tradeable among fishing entities and is set to ensure enough fish remain for future breeding.

The New Zealand hoki fishery is certified by the Marine Stewardship Council, an international non-profit organisation that provides certifications on the sustainability of fisheries around the world. It was the first white flesh fishery in the world to receive this certification.

Hoki Fisheries Management Map


The hoki fishery is managed as two stocks: the eastern fisheries and the western fisheries. In 2017 MPI found both the eastern and western fish stocks have been increasing since 2006 and that the biomass of the western stock represents 40-79% of the theoretical unexploited biomass, while the eastern stock represents 44% - 75% of the theoretical unexploited biomass.

The graphics below show the trajectory of the stocks since 1972.
