Historical AP
Where have you seen this symbol before?
Old-School Aquaponics - Chinampas
Aquaponics supported one of the largest cities in the world
“appear so wonderful… that even we who have seen these things with our own eyes, are yet so amazed as to be unable to comprehend their reality.
Hernando Cortez
Chinampas
Historical AP = Fish + Rice + Ducks
At least 1200 year history in southern China
68% less chemical pesticide use and 24% less chemical fertilizer (ZheJiang University)
"globally important agriculture heritage system“ (FAO United Nation)
Carp Tales
Chinese love carp…. Americans, not so much.
Apparently American animals also don’t like carp They love bass or perch
Historical vs. Modern
Began in the late 1960’s “is often attributed to the various works of the New Alchemy Institute and the works of Dr. Mark McMurtry et al. at the North Carolina State University.” (Wikimedia Corp.)
Modern version is active (historical passive)
Involves continuous recirculation with a pump
Modern materials – tank and growing media are separate.
Importance of AP
Requires little energy Processes fish waste (instead of dumping it)Sustainable

Part TwoMy personal aquaponics journey…..
What and Why…. aquaponics?
People invent many things because they are
lazy.
Part Two
Flavio PelayoMy father-in-law, and Mexican mechanical engineer
My first intro to AP – System 1.0
I’m lazy….Hated cleaning out my fishtank….
Biological and plant filtration
With lucky bamboo!
My 60 cent maid refused to help!
Small-Scale (aquarium) System 1.2
From lucky bamboo to tomatos and an herb garden
System 1.3 and beyond
I dreamed of bigger and better things…..
