Yesterday, we took a trip to Central Greens, Milwaukee's newest aquaponics venture focused on the innovative fish-as-fertilizers model. Central Greens, located near Miller Park, is a family-run business located on a once-run down site in the Story Hill neighborhood of Milwaukee's west side.

|Inside the fish tank: a tube system helps to circulate the water|
|The powerhouse of the system: tilapia|

FertilizerWhile Central Greens is able to sell a number of tilapia to restaurants for additional revenue, the greens are where they really see their 'green.'

Small plants on their way to the hydroponic green house
|Central Greens created small 'rafts' for their seedlings to float on.|
They push the older plants up stream while loading on new arrivals.
|An alternative form of seedling tray - instead of individual pods, all plants are on one large flat|
|Rows of fresh, nutritious greens getting ready to join someone's kitchen counter. Notice the height of plants at the end - once they reach the end of the greenhouse they are ready to be harvested. Brilliant!|
