Without getting into the rest of the issues, let me tackle the fish feed as I believe that the argument about using wild fish stock to feed aquaponic fish is a bit outdated. There are at least a couple of resources available now that sell USDA organic fish feed which is certified to have no fish meal or soy.

The rub is the cost, which at around $3/lb is at least double the conventional feed.

Please see: http://www.theaquaponicstore.com/AquaOrganic-Organic-Fish-Food-s/126.htm
And: http://premiumfishfood.com/ultimate-organic-fish-food.html

From the latter (and no, I don't necessarily know what I am looking at, so if someone with more knowledge can point out other "gotchas" please pile in)

Here are 2 photos which show the limbed Italian Alders

The Italian Alders are dotted about the system. At least two sides of his 2 acre site are protected by pre-existing conifers. I will post photos when I get them downloaded off the camera.

I had the good fortune to tour Martin Crawford's forest garden yesterday. One technique he uses that is relevant to this discussion is that his emergent layer is mostly n-fixing trees (Italian alders) which are then limbed up to the the extent of a telescopic lopper (about 20'?) allowing a lot of light to come into the lower layers. This means that the tallest trees in the system are support species which fits well because of course he doesnt need to climb up to get their products, and also through this limbing system they have a minimized impact on the light levels at canopy level ( mostly 15-25' in his case I would guess).

According to Martin Crawford's "Creating a Forest Garden" not all Alders will coppice well.
OK for Alnus Glutinosa (Common/European) and A. Sinuata (Sitka). Not good for A. Cordata (Italian) and A. Rubra (Red)

Cortland,
Any chanceyou could post your methodology for determining the $$ return and therefore whether a particular crop makes it into the 25%? Maybe one example crop and/or product?
I have tried before to do this and ended up in despair because when I included all the factors that occurred to me I simply had too many variables to make the exercise valid. The factors that I came up with:

Price - varies by channel? (eg CSA, direct, farmstand, etc)
Harvested Yield per unit area
How much is unsold?
Growing season (for annuals - can the same area be utilized before or after for other crops?)
Side benefits (eg bamboo can yield stakes as well as edible shoots, or mulberry leaves can be a forage crop in addition to the fruit.)
Establishment costs (planting, purchase of seed, rootstock etc)
Maintenance costs - weeding, fertilizing, etc
Harvest costs
Post Harvest costs - eg grain threshing, sorting/grading of apples, etc
Processing Costs - eg smoking, making jam, labeling, packaging, etc

If you sell through multiple channels then immediately there is an issue of the different pricing, and assigning costs to products also gets pretty hairy too. Just curious how you solved this problem.

Thanks

A big thanks to all who have helped "lift the fog".

I see a copy of Mycelium Running in my future.

Gratefully
