Fishing methods

Avoid buying tuna caught via the following methods.

 Fish aggregating devices (FADS) with purse seine nets: this method of fishing kills large amounts of non-targeted fish, including threatened species. FADS also have a reputation for washing up on beaches or getting tangled in coral, causing more unnecessary damage.

 Gillnetting or longlining: This is a fishing method generally utilised on an industrial level, it also catches large amounts of non-targeted fish when not closely managed, these non-targeted fish can include turtles, dolphins and sharks. Whilst Australian longlining practices are better managed than overseas it is still problematic.

 

Better methods of fishing

Pole and line caught fish: This method of fishing results in the lowest amount of overfishing and bycatching (accidental capture of non-targeted species of fish). Furthermore, this method of fishing creates jobs for local fishing communities

FAD- free purse seine: This method utilises a large floating net that is drawn tight like a drawstring purse to capture fish

 Labelling information:

 Dolphin friendly: is a misleading term and should not be used to dictate sustainability, this is because a majority of tuna is caught from the Pacific Ocean where dolphins do not actually congregate near tuna, bycatching of dolphins is a much larger issue in central American and the eastern pacific. This is an example of product greenwashing.

MSC certified: tuna with this labelling is certified sustainable by the Marine Stewardship Council, this means it has adhered to the MSC fisheries standards which considers sustainability, environmental impact, and management.
