Rating summary

Giant river prawns are farmed inland and have relatively low inputs such as feed, chemicals and pesticides. There are risks of pollution and prawn escapees from ponds during flooding or water releases. However, the risk to the wider environment is considered low because the prawns are native to the area and disease and pollution risks are not widely reported. Our main concerns are the limited enforcement of regulations for farms and the reliance of farms on wild caught juveniles. Collecting young prawns from the wild also catches other wild species, reducing numbers of prawns and fish in the wild. Although regulations are in place, enforcement of management measures relating to juvenile harvesting and wider ecological impacts is weak. This and other farming practices need to be better regulated.Rating last updated: November 2024
