Yamba
Yamba is Tassal Group’s most southerly prawn farming operation – situated on the Clarence
River in northern New South Wales. At Yamba, we farm our prawns in more than 45
hectares of land-based ponds.
The geographical diversity of our prawn farms results in water quality being one of the
cleanest and highest quality in the industry, while allowing us to harvest fresh Australian
grown prawns over an extended season from November through to May.
Sustainability
Our Yamba prawn farm received the internationally renowned third-party Best Aquaculture
Practices certification in October 2019.
Sustainability is at the core of all that we do at Tassal Group, and farming prawns is no
different. We believe that it is our role to protect the environment that we operate in,
ensuring that the prawns that we supply are of the highest quality and produced so that our
consumers can enjoy them now and into the future.
The Australian aquaculture industry operates under some of the strictest environmental
regulations in the world and we work with government agencies and community groups to
promote sustainable practices.
Yamba Pollution Monitoring Data
We take our responsibility to protect the environment where we farm very seriously. As a
condition of our requirements with the New South Wales Government and EPA, our
Pollution Monitoring Data – EPL 4490 is publicly reported.
