  3. this is a very old thread but i will go ahead and advise, i am pretty sure the Hawaiian golds are not a species , there are just Mozambique( O. mossambicus ) bread for their recessive color trait. blue (Oreochromis aureus) and nile (O. niloticus) are other species...That's not a comprehensive list by any means but they are the most common ones i see in the U.S. There is another popular strain which i call "hornorum" some people call it a "wami" which is Oreochromis urolepis hornorum . The other species of tilkapias (nile, blue, mozambique) tilapias have X and Y chromosomes to determine sex. The hornorum has something different like Z and W. So hybrids are all male. Which is interesting for commercial production but the wami is considered to be more invasive and aggressive than others and is prohibited in more places than some of the other varieties. Usually "red" are niles bread for color too but maybe other species can be red too, not certain. And usually "white" are a cross between blue and nile After saying all of that, i have a lot of experience raising and breeding tilapia but i wouldnt recommend them for a backyard aquaponics system in the temperate U.S. There;s usually a lot better , more temperature tolerant options for people.

  5. Aquaponics is the combination of aquaculture and hydroponics. Aquaponics systems have been used for last many years for better growth of plants. It is particularly effective in areas with poor soil quality. Trout is the most widely farmed fish in the world because it is a prized food fish and is comparatively easier to culture. Trout Aquaponics is right for your backyard. There are different types of trouts are brook, rainbow, brown, etc and these three are main species for best aquaponics system. If you would like to know further details then check out website.
  6. It is important to be know that there are different types of tilapia like The Hawaiian Gold Tilapia, white tilapia, blue tilapia, etc. You can choose the right fish for your set up. Your main role is to feed them and maintain the water temperature and quality. In the wild they would eat diatoms and plenty of blue, green algae. Pros:- Good development and fast growth rate, Easy to harvest Cons:- High temperature
  7. Aquaponics do not need any chemicals. It requires only ten percent of water needed for plant production and as well a fraction used to grow fish easily. It should be aware that there are different species of tilapia. You can choose the right one for your set up based on the way they look or the way they behave. Some tilapia fish like a Gold Tilapia, White Tilapia, Blue Tilapia, etc are good choice for right aquaponics system and you may know more about how to aquaponic setup can be built for perfect growth.
  8. I am still waiting for 2019 for the texas legislature to reconvene and hopefully finish passing that backyard chicken bill. But thankfully there has been some civil disobedience in my city which has resulted in the issue getting re-addressed by the city council. At first i thought it was going to get dumpstered and railroaded by ignorance (again) [cause, apparently this comes up every 10 years or so] but the lady that is appealing the rule got something around 1000 signature on her petition (the city is about 40k population) so i dont think city council is going to be able sweep it away without reasons this time. That's not to say theres has not been a lot of opposition.. I know from my neighborhood social media groups that a lot of people are STRONGLY against other people having backyard chickens . The against arguments that i have heard are , in my opinion, not based on facts or real world data. one of the city council people posts recaps of the meetings and this is what his notes said on the issue of backyard chickens ref:
  9. To make a pond for any shape and to reduce the risk of leaks, you must use flexible liner and in my experience pondpro2000 EPDM flexible pond liner is the best choice. For more details:
  10. Spot on dalep.
  11. Hi iteach, Welcome to APN, Don't forget to post pics of your build and progress in the Aquaponics Systems section. We look forward to watching your progress. Cheers.
  12. Firstly you’ll need to test the water quality, and You can do this using a water testing kits. Any will do as long as you’re looking at the pH levels, temperature, etc. Some factors may be for water quality like temperature, Ph level, electrical conductivity, etc. The pH levels of the water in your aquaponic system are most important. Aquaponic pH control is essential to the health of your fish, plants that makes the whole system work.
  13. Vertical aquaponics can be built at any size. The smallest size could be small enough to fit indoors or even large made for outdoor or backyard use only. You can check complete guide click here
  14. My design has the aquarium overflowing into the bio filter. So I had to lift the aquarium to put the top of the aquarium near to the height of the the 35 gallon drum being used for the bio filter. First mistake was trying to drill hole in a 55 gal aquarium I found out that even that big of an aquarium may use tempered glass. Mine did so I have an acrylic one ordered . I picked a pre cut piece of plywood to put the aquarium on. I then bought a 6X6 and cut it the length of the plywood boards width. I only had a circular saw that I had to cut from the top and bottom so it is not perfect. I cut six pieces and stacked two on top of each other to make it 12 inches tall. But a 6X6 is not 6 inches it so it is shorter than 12 inches tall but the plywood also adds height. It worked for my 55 gal. aquarium. I am waiting on my new one to get delivered. The first pic shows the set up. I then put my black pipe frame that will hold the plants on top. Wood had small gaps to I added weights to hold everything firmly as I screwed the frame down to the wood. The screws go through the plywood and into the first 6X6 to make everything firm. If I make another one I will not use black pipe instead I will use square tubing and just weld it all. I will make a video to show how to make a black pipe square because when you screw in the last threads it unscrews to other end of the pipe. But back to this assembly. I then used a board and screwed it onto the front and put a screw into the front of each 6X6 end. I stained and sealed the wood first. I will add another clear coat after I get it all finished but before adding the aquarium. I ran into a problem on the back because I am not a carpenter the ends do not line up. So I will buy metal plates so I can screw the two 6X6's together. The screws coming down through the plywood are more than enough to hold. Not that it will move when full of water but it is at a school so it may need to be moved some day. I will add more steps ...
  15. I am currently assembling an aquaponic setup in my classroom. I have done some research and will have a steady level using a foam float and an section that will have a bell siphon and media for the plants to grow in.
  16. After dark pest scouting in the backyard aquaponica could also yield some interesting scenes such as these.. - roof touching papaya tree inside a rain-shelter structure, several trees in the trial were cut down due to this - night blooming ridgegourd and snakegourd flowers in the hanging garden - tomato army worm, this could make a leafless plant in a couple of days. Prevention (with a capital P) is better than cure.. an alert to use 'Panchasoothram' from hereon.
  17. I'm building a specific type of shrimp farming system and incorporating a bunch of aquaponics techniques, though my main issue is height requirements. I'm putting my "tank" on a work bench which is about 2'4" off the ground. The tank I'm building is going to be very long and wide (40'x8') and about 2/3' tall. My overflow will end up being about 3' tall, giving me 3' to work with. My question is, whats the minimum height difference I can have between one end of the pipe and another to have consistent water flow. 1", 2"? I realize I'll need to do a bunch of digging, but this will highly influence how much digging I do. Thanks!
  18. Hello! My husband and I are researching and learning about AP. We have a small amount of acreage that we want to utilize as an AP farm. We are excited to learn and begin our adventure! We welcome advice.
  19. First inflorescence of Enza Zaden cherry tomatoes in aquaponics sand culture yield trials.. here is an image FYI. Second most consumable vegetable after potato in the world, first in terms of total nutrients to human diet among vegetables, consumed in fresh form and various processed forms like soup, sauce, ketchup, puree, paste, canned, etc., tomato tops the list of processed vegetables. In aquaponics sand culture, semi-indeterminate Arka Rakshak tomato yields have been proved several times at >150 kg per m2 per year (@4 plants x 2.6 crops x 15 kg). Commercial aquaponics if done right is not a diabolical fantasy. We are very enthusiastic about this trial at NARDC. Today’s consumers want vegetables that are both tasty and healthy (pesticide-free). Priced at average Rs. 150/- per kg (INR), highest being Rs. 300/-, add 30% organic premium rate, there is absolute market potential for cherry tomatoes in India. Your comments?
  20. I experienced almost similar results in some of the old trials.. roots, growth and yield were much better but then most of the systems with looser sand clogged after say 18 months or so.
  21. Yes I do, it's in Hamilton Blues niles
  22. An easy and flawless way to patch your liner is to mend it with pond pro 2000, DIY version of fixing leak of pond liner, easy to use and perfect for joining without trouble. For more details:
  23. Aquaponic systems need some investments at starting But it is the efficient system that will give organic products faster than any other. And The best and easiest way to plan and organize your aquaponic production system is that which products are in demanding at your local market, prices of products, products consumption, marketing opportunities. If you follow all these factors and techniques for aquaponic system but firstly research before you invest.If the system is set in proper way then it will pay off much quicker and allow you to make profits faster.
  24. Here is some data and a picture album dedicated to Today's Fresh Aquaponics, NARDCs CSAF, a commercial aquaponics sand culture demonstration facility at Kollam, Kerala. Plants in focus: Arka Rakshak tomatoes, Arka Anamika okra, Enza Zaden cucumbers, heirloom snakegourd, bittergourd, bottlegourd, lablab beans, stevia, brijal, etc. Biodiversity and polyculture organic farming is key focus in this demo facility. Mean daily temperature: 29/25 degree celcius Precipitation: 20% Humidity: 86% Wind speed: 11 mph NW Flower buds induction and growth/development of new leaves is adequate. Natural pollination seems normal, however, hand pollination is to be practiced well by the operators. Suggested use of an electric toothbrush as well. Plant stretch and stem elongation rate seems appropriate. Plant diseases hardly observed except a few cases of tomato virus. On rain shelter protected structure: A rain shelter is a greenhouse-like unit, in which only the roof is covered with a transparent or translucent material that is impervious to rain. It can either have no or open sidewalls but has no mechanical ventilation or heating system. Rain shelters are increasingly being viewed as more sustainable than totally enclosed greenhouses because they require a much lower initial capital investment. Temperatures in these structures are generally lower than in totally enclosed greenhouses, and if appropriately managed, yields and productivity are arguably higher than in greenhouses or open field production. Particularly in heavy rain areas, its effectiveness is quite high. Challenges ahead: Cucumber beetle Fruit flies Bittergourd caterpillars Mealybugs Sanitation related issues More work to be done in tomato trellis and cluster support. Whatelse?
  25. we have uniseals if yo still want to purchase thankyou
  26. Good Day everyone, I'm new here at this forum, from the Philippines. If someone wants some Aquaponics set up, tools, seedlings and many more don't hesitate to visit our website at If you have question about aquaponics in the philippines don't hesitate to ask. More power to everyone. God bless us all. Jessele
  27. Myself and a buddy of mine are currently starting the design process for a small scale/Pilot project, partial re-use system for raising Tilapia. He recently purchased a farm in a tropical region of Colombia which has a year-round stream/waterfall flowing right through the property. We have been discussing the idea of trying to take advantage of the stream by building a pilot project for an 80% RAS//20% flow-through to get a better idea of the economics behind it before entertaining the idea of anything commercial. The one area where were getting stuck is coming up with the most efficient way to control the water temperature in the system. The temperature of the incoming flow is around 70-71 degrees F, (We've been checking it multiple days at different points throughout the day). Considering were located right on the Equator, There isnt any seasonal changes in ambient temperature...Were looking at year-round avg daily highs of 82-85 degrees, avg nightly lows of 61-63, (overall avg temperatures right around 71 degrees throughout the year. We are trying to figure out the most efficient way possible to keep the water temps right around 75-77 degrees consistently throughout the day. I've spent all week trying to familiarize myself with the Thermal aspect of water temp control but I just keep going around in circles with all of the available ways to heat the water. Were set on starting with 3 tanks, 2000 Gallons each with a replacement flow-rate of around 7 gpm, and the recirculating rate of 27gpm. The tanks will be installed outdoors but we are not opposed to putting up a greenhouse/plastic coverhouse over the tanks but I cant imagine that alone making much of a difference considering there wouldnt be any insulation. Immersion heaters work, but I have to believe there is a more economical way to taking advantage of the climate here. Granted we will have to regulate the temperature through-out the year...we are realistically only a few degrees away from Optimum growing conditions. We realize we will not only have to maintain the temperatures in the tanks, but also attempt to raise the temp of the incoming replacement flow a few degrees to try and keep things consistent. So far i've looked into In-line heaters for increasing the replacement flow temps, immersion heaters for keeping the growout tank temperatures within range, Heat exchangers/pumps to recover some of the heat from the 20% that is exiting the system. But realistically, I cant figure out which might be overkill, in-efficient, or theoretically incorrect lol Also, would incorporating a Solar heating system be complementary? How do I even begin the process of sizing it considering our production parameters? its usually around 75 degrees by 9am, 85 degrees by noon, and 75 by 5pm, so there's about 8 hours throughout the day where ambient temperatures are just perfect. Sorry If im being redundant, thermal energy is just not my cup of tea. But if anyone can point me in the right direction, any insight would be appreciated.
  28. Noble Aquaponics (NARDCs CSAF Alappuzha) had gone live on Friday. A 100 m2 demonstration farm facility, it is an owner operated subsistence farming model, surplus produce sold to the local community. Noble team will lead the aquaponics replication efforts from now on in Alappuzha district of Kerala. It was kindly inaugurated by the Niranam Gramapanchayat President and Agricultural Officer with blessings from all the near and dear ones of Sreenagesh's family. Happy aquaponicing, Noble team!
