we sell live tilapia out of the greenhouse;but, you would have to get a fish haulers permit to produce and sell live fish in IN. The good news its free
I was reading several posts on here and ran across your posts dated several months ago. How has your system come along? Do you have one up and running?
Can you provide the temps Tilapia need in order to breed and thrive year round? You may want to take that into consideration.
You can actually get away with water temps between 70-86 F for tilapia and they will survive down to 60 F and some types even down to 55 F but they pretty much quit eating/growing below 70 F. Some books will tell you that the water temp should be exactly 74 F for Aquaponics but that is for lettuce production I guess.
You say that tilapia need temps of 80 - 85 to thrive and breed. The highest temp I have ever recorded is 78 and that was only in one of my tanks. The rest of the tanks were 75 to 75. Our outside temp only gets up to 89 the water could never get any where near that in the day time . Night time temps go as low as 56 in the winter. That is the outside temp. My tilapia thrive very well and breed a lot so I think whoever made those rules are a little off I just killed several fish the smallest 1 lb and the biggest 2.25 lbs. They are extremely happy fish. Most of my tanks stay in the shade so I keep the temp lower to get the max oxygen. Remember I live in Hawaii and it is 75 to 89 in daytime year round. 75 to 82 is the winter temps and the fish continue to eat and are very happy.
Ah Raychel, isn't paradise tough.
Yes 86 might be prime breeding temperature for tilapia but I've read plenty of statements that say they can start breeding at 72-74 F.
And your temp range Raychel, in the mid 70's seems to support Nelson and Pade's recommendation of 74 being a good temperature.
I think Raychel's success is due to her having little temp fluctuations. In IN it would be more of a concern about keeping the water warm.
