Australia's top restaurants pledge to serve only sustainable seafood

Chefs won't use red-listed seafood including farmed Atlantic salmon and east coast wild prawns

Sustainably sourced fish will be top of the menu in some of Australia's best restaurants after 40 well-known chefs signed up to the Australian Marine Conservation Society's Good Fish project.

The restaurants have all pledged not to source or serve seafood that is red-listed in the Sustainable Seafood Guide, published by the society.
