Aquaponic Gardening

A Community and Forum For Aquaponic Gardeners


Caribbean Aquaponics

To bring anyone in and around the Caribbean that have knowledge and those that want learn about aquaponics together. 

Build up a knowledge base of people and resources to work together and help bring this system of food production into the public eye.

Anyone with a system willing to show others, anyone wanting help, lets start an open group to teach, learn and develop systems suited to our island homes.

Oh.. always have a back up water and air pump, not everyone but us with island homes without big box hardware stores to go to when they fail. (and they will fail)

Ha Anwar. Welcome.

bilge pump? mm they tend to be for on/off use and not constant use as we need. You would find most will used submersible pond or aquarium pumps for small systems and standard above ground pumps for commercial size systems.

not all but my my rule is. Always have more power from your pump than you need, you loose flow every inch of lift and length if pipe you have. Say I have 500gal tank.. 5ft lift and 20ft looped plumbing.. I like to pump the same volume of the tank every hour - 500gph, plus the lift would work out (depending on pump brand) to a 600-800gph pump.  

Rain water tanks are much more expensive than say IBC's plus you get one grow bed and one tank for an IBC or two grow beds from one IBC. I am sure you would have somewhere even on St. Lucia that would have IBC's??

Keep in touch and keep an eye open, alternative building material are everywhere and where you least expect...

I came across the forum while searching on google. I have been contemplating starting a small setup at the back of my house. I live in St. Lucia and material may be a bit hard to come by, but I am trying. I already have a cut black water tank which can 600 gallons, and I just ordered a 500 gph bilge pump, which I intend to attach to a solar panel setup. I just have not thought of the plants as yet. But I have an idea

always use rebar and micro manage to make sure the guys lift it off the ground and keep it centered in the slab.

Ruberizit is what we use. three coats.

We have to find and make our own gravel as the "pea" gravel here has way to much corral and lime stone in it.

Hi guys

I came across this thread on google while searching for aquaponics in the Caribbean. Love the discussion, and have lots of questions once I can figure out how to use this forum. First thing first, I am based out of the Cayman Islands and used murray hallams 'IBC tote' aquaponics. I have a 375 G. Fish Tank with spotted tilapia (caught local), cray fish and a couple of fresh water snails. Everything is going great, I had to change my gravel beds from a limestone based river rock to a non reactive pea gravel recently so I kind of started over. The sun is really hot now in Cayman and I have to build a greenhouse asap to shade the plants (seedlings dont do to well in direct sun).

Stuart Polkinghome - just have a question for you first and foremost - I want to build some concrete tanks asap as well. What do you line them with after they are built? Did you use any rebar?

Thanks a mill.

After the failure of our timber grow beds due to major ant problem, we are now putting in the base for cement grow beds. Tomorrow the slab, walls and finish render will go in. This will be a similar design as the 4000gal system going up in the next few weeks out at Tanio farm.

vermiponics could be the thing you are looking for.

Using earth worms and less water. Look around on this site as some here are already doing it very successfully.

PS the picture below is of the bottom of my compost tea barrel is just PVC pipe with dozens upon dozens of little holes drilled in it wrapped with landscape fabric. there is a plastic garden hose type valve on the outside.

Once or twice per month (twice per month in the summer when the plants are growing faster) I soak five or ten gallons of water in the compost for a few days then drain off the nutrient rich water to feed my plants and supplement my aquaponics system (if the fish waste stream is too small).

I regularly add kitchen waste, yard and garden waste, manure, fire pit ash, or whatever other organic matter I might have to the barrel.
