Revolutionising the scampi fishery
In a project led by scientists from the Cawthron Institute, a Māori fishing company, scientists and engineers have joined forces to develop more sustainable and commercially-attractive harvesting methods for

At present, female scampi ‘in berry’ (carrying eggs under their tails) go to market with the rest of the trawl. Shaun says there is a tremendous opportunity here to add value by using those eggs as aquaculture brood stock, which they are successfully doing within the programme.
“The correct food is obviously the key thing, and a couple of people on our international TAG [Technical Advisory Group] have been vital, with that knowledge about what to feed them. Everything beyond the first larval stage is new to science and it’s really new for us it’s exciting stuff.”
The team are also looking at pot designs for harvesting scampi, and investigating whether the ‘potting’ method of capture can replace trawling. However, early results were not promising: 525 pots of five different types from the
Shaun says it does demonstrate that
This has led the team to develop an entirely new type of ‘Kiwi Pot’, which they have 3D printed and put the components through some 2000 lab trials. Early results are far more promising, but no figures or images of the pots are available at this time as it is commercially sensitive.
