zrumplina diy aquaponics | July 2012 Update Mid Summer heat and bugs

OK...I know its been awhile since I last posted any updates, but as everyone knows, everyday life can consume much of your time just tyring to get by.... Anyway, enough of that. I didnt have much time to dedicate to the plants in the greenhouse due to other responsibilities during June and the 1st part of July, but Im in the process of rectifying that. Heres an update on whats been going on with the whole system.

As you know it can get pretty hot in Texas, and boy it has been. This has been detrimental to most of the plants in my raft system...all of the Squash, & Cucumber plants succumbed to the heat along with some of the more tender Bibb lettuce. Tomatoes and Peppers didnt do well either, but I think this was mostly due to lack of enough fish in my system to provide the required nutrients. The only plants that did well were my Basil, Swiss Chard and Romaine Lettuce plants.

As for the media grow beds inside the greenhouse, I have had to rip most of those out due to an explosion of white flies that started on my tomato plants and rapidly spread to almost all of the other plants in the greenhouse. I had them under control for quite sometime, but I believe the high heat in the greenhouse stressed the plants causing them to become less resistant to the white flies. After removing most of the plants with the exception of my red Swiss chard, some of the mint, basil and rosemary and spot spraying with insecticidal soap, the white fly population has dwindled considerably and is barely noticeable. I will continue to treat for them as I add back plants to the media grow beds. Lesson learned, be consistent and persistent with pest control.

Here are the Media growbeds partially replanted with the remaining plants from my rafts.

and a pics of the rafts after cleaning the surface of the foam boards, the liners were cleaned as well.

On a happier note, due to the increased temperature in the greenhouse, my fish tank water is hovering anywhere from 82 to 86 degrees which has promoted much spawning inside the tanks.

I currently have five broods of baby Tilapia in various stages of growth. I currently up to about 300 fish, including fry and fingerlings. A pic of the latest small fry is shown below, they are gray and hard to see in the photo but show up better in the video.

I also traveled, once again, down to Overton Fisheries to purchase some Red Mozambique Tilapia. I bought forty of these and actually ended up with about forty-six. While most were a solid orange/red color. I had 13 that were partially or fully grey with a red sheen to their bodies. The only way to tell the difference between these reds and normal grey Tilapia is by their Red Eyes. Since this is the first year Overton has offered these Tilapia, I believe their breeding program has not quite gotten to the point of producing pure reds.

I think I will try to breed these back to each other in successive generation to get  pure red females that I can then breed to a Nile Male for all male offspring....Some Im off to by breeding tanks for my next chapter in Aquaponics. I intend to setup some breeding colonies of greys and reds, and once I get my Aquatic species/Aquaculture licenses perhaps I will try some Blues, & Niles.

Heres a quick video update on the aquaponics system...enjoy.
