OneFishTwoFish helps people give back to the ocean, so their seafood consumption is more sustainable. By joining the program you’ll be helping to return more fish to the ocean. You can feel proud about doing your bit for ocean health and becoming Seafood Positive.

Our projects use two methods for returning fish to the sea: 1. Fish habitat restoration and 2. Assisted breeding (also known as fish restocking). To calculate the number of fish returned to the sea through habitat restoration, we use a simplified fisheries model based on a common scientific method (zu Ermgassen et al. 2021). Projects calculate the number and type of additional fish created at one year of age in the newly restored habitat compared to unrestored habitat. The calculations are measured over a 10 year period and we apply discounts to ensure our estimates remain conservative. For assisted breeding, we use the number of fish returned at the time of release. All projects are required to follow our detailed technical guidance document and adhere to our project standards. For a copy of the technical guidance document or for more information on how we calculate fish, please email: info@seafoodpositive.org

OneFishTwoFish captures fees from individuals, couples, families and businesses through annual subscriptions and makes grants to selected projects. These projects use the proceeds to undertake conservation activities that measurably improve fish habitat and populations. The remaining fees are used to provide supporters with ocean-related news and information and to market the program to new supporters.

We can't always replace two fish for every fish sold or consumed on a like-for-like basis, but the initiatives supported endeavour to holistically increase fish stock in the ocean. Read our FAQ 'What's the science behind returning fish to the sea' to find out more about our methods.

Individuals, couples and families who purchase a subscription receive a digital certificate congratulating them on becoming Seafood Positive for a year. They also receive our e-newsletters and special offers and recipes. We provide stories from the projects we support, as well as information on sustainable seafood, seafood recipes, interviews with chefs, and articles on the latest marine science and technology to keep you up to date on everything related to the oceans.

Businesses purchasing a subscription receive access to project images, videos and stories from the projects, marketing collateral, logo use and invitations to special events. We also provide access to our OneFishTwoFish sustainable seafood network that connects like-minded businesses and customers.

OneFishTwoFish only works with reputable organisations with a track record in successfully completing habitat restoration and assisted breeding. We also have a government and industry advisory board to ensure projects align with the latest strategies to improve ocean health. We’re committed to transparency and will post project reports and other documentation on our website so people can review outcomes for themselves.
