I've just been thinking. We can make some funny stuff using aquaculture. Algae grows and reproduces much much faster than using normal crops and plants, capable of doubling their population in 24 hours. In fact, algae blooms are considered to be a problem due to the increased runoff from agriculture of things like phosphorous and nitrogen. Since a whole lot of fish eat algae, you can probably turn the biomass from the algae (I think there's no food that uses it) and turn it into fish flesh to be eaten, either by shrimp or filter feeding fish or snails. Or maybe shellfish. Like oysters, who have a noted tendency to filter out the water they feed on and reproduce in large numbers.
Issue comes with having to take care of highly volatile algae which also contain things like cyanobacteria, who are capable of massive ecological devastation and release toxins that literally no other creature consumes. You might want to genetically engineer algae types which are more efficient and also murder any kind of cyanobacteria in its crib before they can spread out and wipe out your 'crop'. Types of fish would be desired as well, probably something fast growing and really hardy, like tilapia or shrimp (hopefully genetically engineered for fast growth and genetics that prevent them from breeding in the wild). Aeration should be done, although I lack the google-fu skills to really know about how a mechanical aeration of the local pond would affect both algae and larger scale multicellular life.
Hopefully this would be useful for things like preventing overfishing and having a precious protein source in the form of fish and shellfish.
