- How we add freshwater prawns / shrimp to our Aquaponics system. Here at Grow Dinner Aquaponics we raise freshwater prawns and tilapia in our aquaponics system. Here is a short video with some great underwater footage so you can see how it all works.

Ahhh, bottom feeders with their own compartment at the bottom of the tank, with screen big enough to let food through, that's awesome! Thanks for sharing!
I like that screen sytem you built to separate the prawns. Very simple and functional design.
Thank you
Gotta say !!! _ The camera probe was a real nice touch I haven't seen on any other video.
I'd like to see a video on the harvesting of the prawns. New animal to me.
Great! Quite ingenuous way to build an artificial habitat that can simulate the natural. Thanks for sharing.
Spectacular video!! I loved the underwater camera!
Excellent video! Planning my first back yard system and this will save me a lot of trial and error. I have a few questions please:
1) What is the barrier config separating molting/non-molting (are molted smaller and squeeze into a smaller screen sector)?
2) Where do the crayfish stay and why a blend of two crusty bottom feeders?
3) Do you breed the prawns too? Is there a nursery for the female prawns?
great video, nice underwater visual aid to understand the system. Very nice...
Nice system and some awesome underwater footage.
Great setup you have there! Thanks for sharing.
Thank you
How ingenious! Thanks so much for posting this.
All Top Shelf!!!!!!!!!!!!!!!! 1 of top 2 or 3 setups I've found in my non stop search. Prettiest under water photograpy, now looking to find similar with crawfish.
Great job! Awesome video and system. Thanks for posting !
Very cool system. Them prawns are curious little fellers
Jason I am sure we will do a video on them this fall. We don't harvest a lot they are part of the cleaning crew. They are a freshwater shrimp they have a little different flavor then the saltwater but they are pretty good. Building a system here in a few weeks it will have freshwater lobster.
Thanks for watching
Great work here!
this is an awesome set up!
Love the way you say "prawns"
Very well presented. As I look at the netting support structure, I see enough surface area of the pipe to be useful in temperature management of the pool. Not TOO much, but perhaps enough. I live where it is a little cold in the winter and would need some, but not a lot of heat for the pool for 3 months or so.
amazing footage
Lot's of great information. Thanks for sharing.
Well done! Nice design for the pond set up. We are starting year 3 on our small system in Nova Scotia... a bit harder to grow harvest fish without investing in a year round pond heating system but we are looking at it for next year.
brandie Lavoie I would recommend a cover for the pond in colder climate
Jon Baker I have a video of a solar heater I built for my ponds
Interesting and funny....very interesting the set up.
Thanks a lot man, awesome video.
Cool info and thanks for sharing this
IM GONNA BULID IT!
Great video. Its very informative. Thanks
PRAHHNS. Love your accent,... but I have never heard them called Prones.
Your video gave me some good ideas. Thanks...now I know what to do with that pond thing I got ages ago.
Thank you am from the south!
Holy fish crap, Batman! Best vid on aquaponics EVER!!!
Great video. Do you have a video or other information regarding the tanks you use? I'd like to do in-ground tanks inside a green house with with grow trays above them.
In my small greenhouse I use IBC tanks the pond is a hole with a pond liner
Great videos and great tips.
Thanks
Thank you
Thanks Crayfish would help some with cleaning the bottom I have a few in one of my systems they do ok but not as good as the prawns.
cool video have you though of adding gravel to the bottom and pipes and niches for the prawns to hide?
Try adding some scuds to the system AKA Gammarus shrimp. They help keep my redclaw crayfish system going and can handle off the chart nitro spikes when a new system is cycling.
Thank you Sam I have some mud bugs in my system they work good but I have them in my duckweed and sub tanks
Thank you and yes they are big prawn stars I will be sure to use a star plate when I am having them for dinner one night lol
nice thank you. hard to tell if those prawns are actually getting up in the layers?
amazing !!
thank for the info..great
Very Nice! The prawns seem like they would add yet another layer of goodness! Do catfish work in such a system?
Thank you Bob
Great vid! Thanks!
Patriot John Adams Thank you
Like it. The prawns like the camera. I guess the are now prawn stars;-)
Nice set up. :)
Thank you
awesome
How do you deal with the water once it's used up? is it harmful to the ground?
Great video, thanks a lot
SO WHAT DO YOU FEED THE FISH AND WHERE DO YOU GET THE FRESH WATER PRAWNS AND TILIPIA TO PUT IN THIS SYSTEM?
I will try to build this one. I love tilapia, prawns/shrimps. I just need to find where to get the equipments.
Thanks Bill
Good one and informative. It is a lot worth growing Prawns/Shrimps than Tilapia in terms of economic value.
Curious how you made the drainage from your beds to your main fish pond. I can think of ways but I wonder how it could affect the siphon.
nice video thanks
Thank you
What species of prawn do you have in this setup?
THANK YOU
Thank you I had one or two to come close to the lens
You are very welcome thanks for watching
Thats awesome!!! Great ideas. Do you have any tips on controlling ph levels in a natural manner without sacrificing plant quaity? Thanks in advance.
This a video thats shows what I use on a new system setup How to lower and raise pH in aquaponics systems
I do in some of my tanks but the neting works best for me in the ponds
You need an HD GoPro for those underwater shots and to get a sharper picture. It would be awesome to see the system in high def. Thanks for sharing!
Well done.
Not sure fresh water prawns are available here, 25 mins north of ATL.
Have seen tilapia for sale, but not sure about making it thru the winter.
Can you suggest any books or instructional materials for someone looking to start a similar system?
Hi, what other creatures could you put in with your fish, albeit separated, which would clean the bottom of the tank. Also, Talapia prefer warm water, and I am going to use Rainbow Trout because they prefer cold water which is easier in my climate. So my tank cleaning critters would also have to thrive in those cold temperatures. Thanks. Good video, everything well explained.
about all fish work I have catfish, koi, trout, crayfish and prawns
Would it work to put them in the sump tank? If so what kind and where you get them and what would you feed them?
You are very welcome
fish looks really healthy
Thanks and I have a prawn nursery
Have you tried red claw crayfish? Also how do you harvest the prawns?
Thanks
Thanks you
If you will bait the camera with a little of what the prawns eat readily, they will come right up to and around the camera lens. Nice informative videos.
Very interesing....i suppose lattitude is most important ?
have you thought about putting freshwater mussels ? also how do you spawn more? freshwater prawns
I keep prawns alive in the winter and I am in North Carolina.
Great system and video. Where do you get your baby shrimp/prawns from?
Grow Dinner Aquaponics we are a hatchery
Would you ship to NYC?
Yes we ship shrimp in the spring
Do you have a brand of bird netting that works best for you?
Nice vid, but did the prawns start as eggs or already matured from somewhere?
Its just like Prawn Big Brother.
Very Cool! How much work/time do you spend each day once your system is in full swing? Also, what would be an approximate start-up cost for a 3 tote system, and how much water would you need per month/week? I have a well so this is a consideration for me.
Thanks
Virginia Patton Cost can be little or as much as you want to spend it all depends on what you want. I spend about 5 mins per day in the greenhouse and one day a week I spend about 1 hour
It is easy to build an aquaponics system from home, whether it is indoors or outside in the backyard.
would it be practical / useful to introduce freshwater mussels as cleaners?I imagine them in a tank after the fish, perhaps on a base of sand that the water would be drawn through as a further biological filter
I have a few crayfish in my system. Harvest catch and eat
like your pond, I got a hole in the back yard. This is what I need to do with it. However, I will have to put a screen or fence over the top. we have a lot of cats in the neighbor. been trying to catch them. What do I put down in bottom to whole the water in?
Pond liner
Are talapia in the chiclid family of fish. They sure look like the african chiclids I used to have in my aquarium years ago.
How do you heat the water during the winter, been wanting to move my system outside but im concern with water temp during the winter, great video
That would depend greatly on your climate. If where you live your pond waters fall below the fish's survivable temps for more than one month it would not be economical to attempt to heat an outdoor exposed pond. The only examples I know where this is ever done was an emergency save measure for a geothermal naturally heated koi pond in unusually low temps for that keepers area (watch Greenpower Science Solar Thermal Geothermal large pond heating with giant Koi Fish). There are DIY rocket stove water heaters you can build, one is an open loop system that you have to consider the problem of overheating the water or scalding fish that swim too close to the outlet, and there's a closed loop system that you have to worry about venting the radiators and risk of explosion. It too may not be economical or feasible depending on how hard your winter freezes are and how long they can possibly last. Remember outdoor heated water also evaporates quickly in the winter, you would have to find a way to preheated refill water. For extreme winter weather you could build a building or greenhouse around the system and heat the building with your most economical system for your area, ie: woodstove. This way would reduce the evaporation. You will still need to consider preheating water for any topping off and partial or full water changes in your system. You will also want to ensure that your structure can handle snow loads without collapsing. If your soil freeze line is more than half as deep as your pond depth, you would be better off keeping your pond above ground because your heating efforts would be fighting the lateral travel of cold transferring into your pond, unless you have a very good insulated build for the walls of the pond. Above ground in a heating building would be the less costly way to go in terms of building costs. If your temps are mild and you don't have heavy snow worries, you could get away with building a hoophouse cover over your inground pond and let the sun help heat it in addition to your heat source for those cloudy days. Warm air does not want to go down into water easily, circulation to the surface is essential.
This is a summer pond we harvest before winter
The mussels I don't think would clean as good as the prawns. The gravel grow beds are our filter
You have a very nice set up there. I am planing on building a 3000 gallon pond and raising about 100 Tilapia and about 10 catfish. I have searched over the internet to see what I could find on what they require the best answer I could find is 2sq ft of bottom area to a shrimp. I love the size of your set up I was wondering what works for you?
Adult prawns need about 2 sq feet per animal but they need a place to molt the old shell as they grow that is when other prawns will move in for the kill
You say you just give them space? Don't you need rocks or hiding spots for them to stay safe while they mulch? Also you said you used side rails to develop a tight holding for the mesh screen right. I know it's to separate prawns from fish but you managed to design it to be a tight fiting all around?
Erik Maguina Yes it is a tight fit.

So where do you get yours. thank u
Hi. I just watched your video and I realized that your setup is not covered. What effect does rain have on your system?
+Gerty Hattingh It lowers the pH that is the only problem with having outdoor systems.
We have a prawn nursery and sale prawns in the spring
Yes
what would you use if it were not tilapia? cause in Utah tilapia are treated like a controlled substance?
I have a prawn nursery and have them for sale each spring
Did you use a concrete tank? Is there anything special about it?
what is the stocking density of prawns to your set up?
Its a loop system the water is never used up. You are very welcome
did the prawns work out?
I just use the diy solar that is other video for warming my ponds
