This could change the world some. A step towards the 'holy grail' of aquaculture-

"A justifiable criticism about aquaculture is the continuation of catching wild fish, grinding them up and feeding to farm fish." 

News of Novaq's development has caused huge excitement around the world, as many thought a fish-free food was impossible.

"It's the first really viable solution to not having to use wild harvest fish meal," Dr Preston said.

Australia's only producer of prawn food, Ridley, has the licence to make Novaq, and aims to have it on the market by the end of next year.

Did you read the article? It's a licensed product going to market this year. CSIRO is not generally in the 'yap yap' business.

As oil becomes more expensive, so does running the fish haulers. Eventually the idea of putting a diesel ship to sea to gamble on catching dwindling wild fish is becoming untenable, that's a large part of why fish farming is becoming so popular and important.

In much of SE Asia species like Milkfish and Tilapia are very popular because you can feed them almost anything, including maggots and to some extent faeces.

The article mentions peak fish. This includes what used to be thrown back as 'by catch' but is now kept to be mulched into fish food for farms. There is nothing 'free' about it. Ask anyone who runs a fishing boat.

Man you must be smoking some fine, they are growing the fricken microbes.

In any case, manufacturing or collecting microbes to mash into fish food has got to be more expensive/energy-intensive than ripping off ecosystems for the free stuff.

While they cynic in me agrees, the article seemed to be dealing with the problem of falling catches of wild fish to use as feed - so the hunt is on to find some other source of input. Like using alternative energy, because we can't get enough fossil fuel (except the microbes seem to be more to the prawns liking than chopped fish, but alternative energy can't get the energy density of oil).

I have a cousin. He is secretely (the silence of the bow) harvesting white tailed deer and canadian geese from suburban areas. They are His. They are His.

The Canadian Geese and White Tailed Deer Lobby are very concerned about resource depletion and climate change. Their constituents are very worried indeed.

My cousin is an outlier at the moment. Only 1 of 10,000 who pass a deer or goose on a lawn and earns a double bonus harvesting them; free meat and correcting an imabalance. Both his belly and environmental ethics satisfied with one twang of the bow.

These are still good times.

Sounds like sound animal control.
