Description
The new series of reader research projects starts with an exciting plan to turn grass clippings into organic fish.
After some study and experimentation, we have set up a productive food chain--table scraps to earthworms to catfish--in our back yard. The project is satisfactory in many respects, utilizing waste materials to produce fresh fish for food and at the same time yielding ample compost for a small garden.
The material cost is minimal. The whole operation can be set up for less that $15.00. The equipment occupies only about 12 square feet of space, and the entire assembly can be easily moved if necessary.
