Fish Waste- Duckweed Treasure

March 5, 2012
tags: , , , ,

This is one of my favorite videos showing how to grow duckweed in tanks to feed tilapia, etc..What I like about it is that it shows the connection between plants, animals (fish in this case) and the wastewater nutrient cycle. One fish’s waste is another duckweed’s treasure. Fish eats duckweed. Cycle repeats. Everyone is happy.
