Responsible fishing

There’s more than one way to catch fish, but we have high standards and expect the same of our fishing partners too. We only work with partners who are committed to catching fish in the most responsible way, so the chances of other sea life being caught in the process is very low.

As a founding member of the International Seafood Sustainability Foundation (ISSF), we work closely with some of the world’s top scientists to help improve standards in tuna fishing.

Proactive Vessel Register

Proactive Vessel Register

When we purchase tuna from large scale purse seine vessels they must be registered on the Proactive Vessel Register (PVR). To make the register, each ship’s captain must be trained in how to minimise bycatch, ensuring responsible tuna sourcing.

We only work with partners who are committed to catching fish in the most responsible way so that together we can help to preserve the future of the world’s oceans and improve fishing standards.

We not only invest in research that helps fisheries towards MSC certification, but we work with current MSC certified fisheries that are committed to sustainable fishing practices.

Dolphin friendly

Dolphin friendly

All Princes tuna is dolphin friendly and as an approved and compliant member of the Earth Island Institute (EII), we only work with fisheries that reduce the risk of dolphins being unintentionally caught in the tuna fishing process (known as ‘bycatch’).

How do we catch our fish

Tuna

Our dolphin friendly tuna is caught using pole and line or purse seine net fishing, so the chances of other types of fish being caught up in the nets is very low.

Pole-and-line

A simple fishing pole and a baited hook is used by our fishermen to catch tuna one-by-one. This highly-selective technique minimises the chance of other types of fish being caught.

Purse seine nets

Purse seine nets sit upright in the water with their bottom edge held down by weights and their top edge supported by floats. Fishing boats tow the net to surround schools of fish. Catching fish this way cuts the chances of catching other, unwanted types of fish unintentionally.

Salmon

Our fresh packed salmon is wild caught in the Pacific Oceans using purse seine nets and gillnets. The size of the holes in the gillnets means they only target salmon, while other sea life can swim free.

Gillnets

Gillnets work by catching fish which try to swim through the mesh nets. The size of the mesh is designed specifically for the Salmon meaning that the bycatch of other fish is very low.

Purse seine nets

Purse seine nets sit upright in the water with their bottom edge held down by weights and their top edge supported by floats. Fishing boats tow the net to surround schools of fish. Catching fish this way cuts the chances of catching other, unwanted types of fish unintentionally.

Mackerel, Sardines & Kippers

Our mackerel, sardines and kippers are caught using trawl nets and purse seine nets, which don’t touch the sea floor. This helps protect the oceans and minimises the chance of catching other sea life unintentionally.

Trawl nets

These cone-shaped nets are dragged through the mid-water behind a trawler. Because they never touch the bottom of the sea, there is no danger of them damaging the sea bed and destroying marine habitat. Bycatch levels are also typically much lower than other fishing methods.
