Feed Supply

Aquaculture diets traditionally have been dependent on wild caught fishmeal as an ingredient. In some countries this fishmeal has been sourced in very unsustainable ways. Here in Australia we have worked towards replacing the fishmeal with sustainable alternatives.

The CSIRO recently developed Novacq® as a fishmeal replacement. Basically they worked out how to farm the tiny marine organisms that prawns naturally eat in the wild, harvest them and turn them into a commercial feed ingredient. Not only did they achieve 100% fishmeal replacement but prawns actually grow 30-50% faster on their diet.

Whilst we work towards full commercialization of Novacq®, Ridley Aquafeeds, the Australian supplier of prawn and fish diets, has developed its Perform Plus Nocatch™ diet that utilises specialised ingredients which include by-products of human food fish processing facilities to replace wild caught fish meal. This makes us ‘positive net fish producers’- instead of using more wild fish to produce each kg of farmed prawn we use no wild fish at all.

We source all of our Cobia feed from Ridley, and they have been instrumental in developing what has been a new diet for a new aquaculture species. This has been a tough learning curve, however their technical expertise and their strong desire to help develop this new species has been critical to the end result.

Ridley have a strong sustainability focus including sourcing inputs from accredited sustainable suppliers and where possible Australian suppliers, and are Global GAP certified. Ridley has a five year goal of having all aquaculture feeds achieve positive net fish production.

We are also working on novel ways to feed the prawns, to ensure they get the right amount of feed when they want it. This is ideal from a growth and cost point of view, but it also helps to minimize the waste feed that would otherwise end up as nutrients in the water. We have been working with AQ1 systems for the last four years in developing an automated feeding system that detects how much the prawns are eating and feeds accordingly. The system uses advanced computing systems that provide real-time information on both feeding and water quality to management.
