Thanks Fred! Yes this is an excellent fish, we got it in Europe as well. We call it Black bass (Micropteus spp). They are great predators and fantastic to eat Are you growing them in aquaponics Fred?
Melbourne Aquaponics , thanks for replying, I am curious about density in my system, system will be about 4000litres between bed and tank, tank is currently ibc tote but upgraded. How many speckled trout would you put in a setup like this?
I have noticed this with my fertile trout that the males mature after just one year, but I usually raise sterile rainbows to get better growth. I have considered getting fertile rainbows again and breeding them myself. Great information about the females! I did not know they need to expel their eggs or they will get sick and die. Thanks for the video.
Thank you very much for the video, very interesting. I wonder whether you have thought about feeding home-reared insects to fishes. I think it should improve even more the sustainability of the whole system. Thanks again
Thanks Irontoad, Fortunately I am slowly improving Are you learning anything? Is there a specific topic you would like to be developed? Cheers Jonathan
I am going to build an aquaponic garden when i move next year. I will start with yabbies and then trout. your vids are very helpful because you are local. I am in melbourne. I have read a PDF from UN called small aquaponics. its very generic. id like to develop systems for small yards and balconies in melbourne in summer cooling and evaporation are probably important ideas to work on. @@AquaponicsRevolution
@@AquaponicsRevolution actually that's my future plan and now i am just trying to inform myself and get ready for the future plan. By far your experience and the way you explain things is the best. great job and thanks.
Hello Jonathan, I noticed in your thumbnail that it showed a male trout, and i was wondering if you had male trout in your aquaponics system? Thanks and keep up the great content.
Hi! Thanks for the video! I got stuck on the 50ppm value. Plants usually need high ppm (800 and higher), how to achieve that? Evaporating water to increase concentration of nutrients? Thank you!
Hello Antony. Yes you are correct, in hydroponics we very often work with higher nitrate concentration. However in aquaponics we can't afford those values as the fish wouldn't enjoy it. Plants growing well at 50ppm. nitrate are produced constantly so they are always available for the plants :)
@@AquaponicsRevolution wow! Thanks for the quick answer! So you compensate lower ppm with higher water flow? I have a good experience in hydro and aeroponics and want to move towards aquaponics. Really interesting technique!
Great video! Very informative! I think your video is one of the very best I have found, concerning raising trout in aquaponics. Do you have any ideas or recommendations for keeping the water cool without the use of chillers? I have considered running a lot of plumbing deep underground to keep the water as close to constant as I can. This may also help me winter them, as we can reach -17 degrees C, or lower. Thank you for the amazing videos! Subscribed/
@@AquaponicsRevolution It occurred to me yesterday that without a greenhouse my biggest challenge will be keeping the bacteria colony alive. At those temps I wouldn't be able to maintain the nitrogen cycle. Have you ever seen it done or had success with a similar challenge?
Get an old mini fridge or larger, depending upon needs. Run from tank to fridge a length of garden hose and maybe about 100 feet of coiled hose inside the fridge and returned to fish tank. Buy a very small pump so water can continuously flow in a loop. You can adjust fridge temp. with fridge setting and also have a valve in the hose line to slow or speed up the flow. Simple and ultra cheap. You may be able to use a freezer and I for got to mention, you obviously have to drill 2 holes in the fridge to run your entrance and return hose.
Thanks for the video is very intresting! Giving the requirements of the "society effect" to avoid having some of the fish stressed, waht is the minimum size of the fish tank thta would allow this? If I have a fish tank of 300 liters and I plan to grow the fish untill they are 300 grams each I can have 10 fish correct? Do you think would be enough to avoid having a dominant one? Or it's required a bigger fish tank? Thanks a lot!
Enjoy your video's . Started to set up my own system here inland NSW. We are at 900 metres above sea level so get cold weather in the winter down to minus 7 and in summer up to 37 degrees. Bought a dozen Jade Perch from Queensland two weeks ago. Arrived safely but had cold night and they died!! Want to try trout as you have but not sure if I can keep water cool enough? Any thoughts and advice would be appreciated. Thanks.
Yeh thats a bit of a prick of a spot. A greenhouse through the winter maybe. Im western sydney and i have an annual water temp range between 12c - 30c. Jades dont like the winter and i lost a few. I have Tandanus catfish now, they can handle it all. Silver perch and trout wont survive the summer and Jades dont survive the winter. I heated my 2000L system with a 2kw immersion heater a few seasons ago to keep the jades alive over winter, expensive obviously so wouldnt recommend
@@MrWackozacko Just had a look at your aquaponics video Odin. Looks good. Fish can be very temperamental can't they. Alive and healthy one minute and swimming on their side the next.!!
@@rogercutler2033 It can but only around 200W worth for 4 hours, not enough to even register on the thermometer. I tried with those heat mats for a pool and they do make a difference but i didnt have the sun exposed surface area to make it worthwhile. Annoying because the growth rate of everything is closely tied with the temperature. Perhaps half burying your fish tanks and then a greenhouse over the top, the soil temp stays fairly constant and never gets as cold as a frosted lawn surface. Even a coil of copper tubing chucked in a fire and water pumped through
Im in Canberra.nice weather for trouts "I think".was thinking of trying barramundi but it may be a little cold for them. Thanks for the feedback Cheers
Hello Jack, I really recommend you to get the free training available in the description of the video. It will respond to your question and much more. From my perspective the quantity of fish shouldn’t be determined per number of fish per volume of water but kg of fish biomass per volume of bacteria media. Passionately, Jonathan :)
It's well known to not leave the trout in a dark environment with no natural light bounce. It significantly stresses the fish when the hatch is opened.
I am in the NE of Victoria, Summer temperarures up tp 40 degrees, Winter temperatures around 10 degrees. Would like to have the plants at least under plastic. How do I control the temperature for trout? Or should I grow another species?
Hello Chris, What most people do in Melbourne area is to grow the trouts for 9 months. Basically we get the fingerlings or yearlies at the end of summer and harvest them by the end of spring before the hot days. The fish will have reached the plate size 😉. Have you got a running aquaponics already?
I have a very small CHOP system in my front yard in Bangkok, with Redclaw crayfish, Maybe cod or Jade perch would be more suited for growing in a hot house here in Victoria?
Thanks Hexisan. I got someone doing the subtitles for me and he always mix them. Thanks for the pickup, I will fix it 😉. Are you growing trout as well?
Need help ...my trout started dying after a heatwave, stoped feeding and now it is more than a week since I sorted the temp problem and are now at 18 degrees Celsius gave them some food and started to die again...what am I doing wrong, how long must I wait till I start feeding again...they are still small, alsobisolated them from my system and did the salt bath days ago...please advice..
Hi Franci, were are you based? Yes here we got a specific setup placed in a shady area to grow trouts so the water temperature never really raise. You can also insulate the fish tank or put the fish tank / sump tank underground. Cheers
@@AquaponicsRevolution yes I have started already about a year ago. Temperature in winter on average is about 10-20 degrees C but can go down to 0 on a cold night. The average day in summer is about 25-30 degrees C and can go up to 40 on a really hot day. I have mostly tilapia, and few Koi fingerlings and comets. I have grown broccoli, cherry tomatoes and basil in gravel bed and chard, lettuce, mint, rosemary in dwc. My setup is outside and north facing so it gets full sun. Have to use shade netting in summer otherwise plants wilt and water temperature spikes.
Excellent! If you feel like it you are very welcome to send me a video of your setup here: melbourneaquaponics.com.au/contact-us/, I could make a review if you like. Cheers😉
I tried to download the free guide yesterday and today and I keep getting a Service Unavailable 503” error. I want to grow trout in a standard size above ground IBC tank in central valley California. It gets super hot here during spring and summer. What refrigerant system do you recommend?
Sorry for the inconvenience. I fixed the issue, you can now get the free guide there: aquaponic.subscribemenow.com/ I don't use refrigerant system but play with different parameters like depth, shade and rafts.
Melbourne Aquaponics haven’t done any yet I’m still studying and trying to figure out what type of fish would do best in my region , but I have to say you’re video was quite informative.
@@Roadsaftyslowdown you are very right however the only fault in your thoughts are in regards to a black out or a power out or whatever they call it in your area. If the power goes out the venturi can't oxygenate the water as there is no pump pumping the water to the grow bed which then activates the venturi (a no power way of adding oxygen into the water before it hits the fish tank, for anyone reading that doesnt know what a venturi does). It seems most people like to hook up the pump to a backup power supply to combat this issue though so under those conditions you are completely right. Remember, no oxygen in the water, your fish will die, ALWAYS, ALWAYS have a back up supply dont make the same fatal mistake many others have done due to being too tight or too lazy to do it right properly
Sir pleas help me ! For example I have 600 m2 dwc space to grow lettuce ,following size of 6 time dwc 4x25x0.5m . 1-How much size fish tank I'm going to need ? 2-How many kg fish I do need? 3- How much kg I need to feed fish per day ?
Honestly if you ask those questions you are probably a beginner and if you are a beginner you should never plan such a large scale system. The secret is to start small and grow big 😊 Start with the free aquaponics training and you will grow your skills until you can scale up to a large size system. Where are you from? Cheers
Hello Sian! Yes if you feed your trouts with shrimp it will definitely colour the flesh but will you be able to produce enough to feed your trouts? What type of system are you using to grow your shrimp? Cheers 😉
Thank you so much for the quick reply and I thought that it would be illegal because it is an invasive species. I would also thank you for the free six-step training as it had helped me to have the first step to a completely new way of growing and farming plants and fish.@@AquaponicsRevolution
Hello Fishmut, all trouts are not injected. I worked in farms where we did inject them for vaccination but it's not everywhere. Most of the farms are using antibiotics and chemicals to regulate the disease population though. The meat industry is probably not better but we can change things by growing our own food 😉
Melbourne Aquaponics thank you , definitely agree on that one , I’ll be setting up a small system before the cool about April here and try about 8 to 10 trout in a chop in drop tank method harvest about November before it gets to warm if everything goes well, great vide to btw cheers. 👍
Its incredible how people like this don't realize we don't want to see you talk. We want to SEE what you are doing. That's called a video. If we wanted the data we'd read it and get the information much faster than you blabbering on for 22 mind numbing minutes. Unbelievable how so many RU-vidrs just don't understand common sense. And buy a real camera. This looks like it was shot from a pinhole camera.
@@AquaponicsRevolution Sounds good. What you want to strive for is to try to demonstrate as much as you can so there's a video story along with your vocal story.
