There are excellent discussion forums/subreddits at Reddit for aquaponics,
anthroponics, hydroponoics, aquaculture and aeroponics:
hydroponics http://www.reddit.com/r/hydroponics
Hydroponics is a method of growing plants using mineral nutrient solutions,
in water, without soil. Terrestrial plants may be grown with their roots in
the mineral nutrient solution only or in an inert medium, such as perlite,
gravel, mineral wool, or coconut husk.
"...There is intense global interest in Novaq because it solves one of the
farmed prawn industry's biggest problems - its reliance on wild fisheries
as a core ingredient in prawn food.
But aquaculture has reached "peak fish", where demand for wild harvested
fish meal now outstrips supply. Without a solution, soaring world demand
cannot be met.
"It is absolutely a critical issue for the global aquaculture industry.
There's no more room to get more wild harvest fish, so we've got to find
alternatives," Dr Preston said.
"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..."
