September General Meeting Tuesday, September 2nd, 2014
Water Quality - pH, TDS, e.c., nitrates, nitrites, etc. - what does it all mean? What really matters? Come learn both theoretical and real-world water quality analysis and remediation. Bring you own pond or aquaponics water sample for a hands-on analysis as part of this interactive workshop as we teach what, why and how to provide the best possible water for your aquaponics system.
6:30 PM - Intro to Aquaponics lecture
7:00 PM - Questions and Answers
7:30 PM - Feature Presentation: Water Quality for Aquaponics
The Tucson AquaPonics Project is proud to have the support of The University of Arizona College of Agriculture and Life Sciences Controlled Environment Agriculture Center (CEAC) which is providing the use of their SmartClassroom for free for the monthly meetings of the Tucson AquaPonics Project.
The meetings, held on the first Tuesday of each month, are FREE and open to the public.
Come learn about aquaponics and how you can participate. Go to our Meetup page for more info and to join the conversation.
We build a single-tank IBC system (International Bulk Container system) from start to finish, discuss different options for AP systems and building materials and the basics of what it takes to get them running. We provide an instruction manual for you to build your own single-tank IBC system, complete with recommended sources for parts.
Each Building Session attendee will receive a 10% off coupon for supplies at Eco Gro! (excludes IBCs)
Water Temperature is the Key
The most commonly grown fish in aquaponics systems are Tilapia.
However, you do not have to eat the fish you grow. Many people use Goldfish, Koi or other species.
The photo on the left is of a Tilapia that jumped out of its 300 gallon Rubbermaid tank last month. It is just barely big enough to be considered harvest ready. Tilapia are normally harvested at 1-1/2 to 2 pounds. (The water level of the tank was lowered to prevent this in the future as the tank contains many plants and would be difficult to cover with a net.)
Tilapia are warm-water fish. They like 80 - 90 degree (F) water, but generally begin to die as the water temperature drops below 50 - 60 degrees (F) depending on variety. Tilapia are easy to grow, eat a wide variety of foods and are considered very hardy and disease resistant.
Other types of fish used in aquaponics systems include Bluegill, Channel Catfish, Largemouth Bass, Crappie, Pacu and various ornamental fish such as Angelfish, Guppies, Tetras and Mollies in warm water and Lake Perch and Rainbow Trout, among others, that live in areas that have colder water.
Dr. Stéphane Herbert-Fort runs Local Roots Aquaponics, a small aquaponic farm in central Tucson. Local Roots Aquaponics is providing all-natural aquaponic produce to Tucson residents and restaurants. You can find them online at localrootsaquaponics.com or on their public Facebook page, where they frequently post.
