Throwing a more sustainable shrimp on the barbie
This blog by researchers Cedric Simon and Ha Truong from CSIRO Agriculture & Food discusses a method they have developed to reduce the amount of wild fish needed for prawn feed.
Research has shown that prawns can grow 20 to 40% faster in controlled tank environments when a specially developed feed supplement called Novacq is added as a feed ingredient (at 10% inclusion). Prawns also perform better on low protein diets when Novacq is included, allowing for production of prawns with less need for fishmeal from fish caught in the wild.

This region of Oceania comprises Australia, New Zealand, the island of New Guinea, and neighbouring islands in the Pacific Ocean. Its ecozone forms a distinct region with a common geologic and evolutionary history which has resulted in a set of unique types of animals and plants. Due to the reverse seasonality with the US and Europe, much food produce is exported to these countries in the winter from Australia and New Zealand. Except for the lush rainforest of Queensland and the east, much of the Australia is arid and unsuitable for arable agriculture. The country is considered highly vulnerable to climate change and associated impacts including droughts and wildfires.
