Beefing up our prawns

Ahh prawns, delicious sea bounty. Some people hate them, most people love them. Paul Hogan cooks them on a BBQ. But with seafood on the menu for many people this Good Friday, spare a thought for the Aussie scientists who are working hard to help prawn farming sustainability.

Nothing fishy here

Around 50 per cent of prawns eaten in Australia are imported from overseas. Most farmed prawns are produced using feeds containing wild-harvest fishmeal, contributing to strain on global fish stocks.

The problem is pretty obvious – we need to feed prawns something other than fishmeal or our insatiable appetite for prawns could ruin our oceans.

Luckily our scientists love fixing problems. The team spent several years learning how to manipulate marine microbial organisms to maximise their productivity in controlled environments, and stimulating them to produce a novel bioactive product to enhance prawn growth.

Didn’t quite catch that? Essentially, they’ve invented an ingredient to go in prawn feed that doesn’t contain any fish. In fact, it’s made using low-value agricultural plant waste so it’s actually solving two problems in one!

Mo’ money mo’ prawns

The product, called NovacqTM, isn’t just helping the sustainability of prawn farming, it’s basically a prawn super-food. Prawns fed with NovacqTM are healthier and grow on average 20–30 per cent faster. So not only is it better for the environment, it means healthier prawns and a more sustainable industry. So, it’s a win, win… win situation.

2017: a land odyssey

“What about me!?” a prawn-hater reading this might say (if they got past the first sentence). “I want my food to be farmed with sustainable feed, too!” Well, never fear you unicorn-like creature (seriously, who hates prawns?!). We’ve just extended our partnership with Ridley Aquafeeds to further our research and knowledge of the Novacq TM technology to see if it can be used as a stock feed additive in a range of species, including land-based animals.

So, as you throw another prawn on the barbie (thanks Hoges), raise a glass to our scientists for being generally awesome and making your meal that little bit better. Oh, and if you’re looking for cooking inspiration; we’ve got the perfect prawn recipe for you.
