As I said in part one, you have to become a resource for others. The apt fishermen and women of our nation who are prepared to live on bass and catfish for extended periods of time will need to catch bait. As part of the whole "assets that throw off food" concept, you need an asset that will throw off another asset on a regular basis. Raising worms is one really cheap way to do that.
You need some heavy duty plastic tubs for storage. These are available for cheap from flea markets, garage sales, and if you must pay retail, for under $5.00 at walmart. I don't pay retail. Collect as many of these as you can and drill 8 holes in each side and 30 or more holes in the lid. Fill the containers with soil from your garden, some composted fruit rinds, coffee grounds and old newspapers. All of which you can get for FREE.
Order some night crawlers from a vermiticulture website or what ever worm fits the fishing needs for your area, some like red wrigglers, others prefer the giant Canadian worms. Toss the worms in the soil and close the lid. The worms will be doing what worms do and three weeks to five months later your worm population has doubled, tripled or more. So far your only real expense has been the plastic tubs, got it?
Barter one-fourth of the worms you have now and let the rest keep well doing the worm nasty and making more baby worms. As the population grows, empty some of them into other containers and your population explosion just won't stop. This can be done in a garage, a spare room or a shed when extreme temperatures are not a problem. Feed them your trash as long as it's fruit, coffee grounds, leaves, etc. Still all this food is trash to you, so you haven't spent anything on it at all.
If the tubs get too many worms, you may want to have a supply of lime on hand to reduce the pH level in the soil. (That's another $5.00 for a bag.)
Worms are sold for close to one dollar each in bait stores. Trade the worms for some fishing equipment and you can begin feeding your family.
