The number one issue in aquaponics is the uncontrolled reproduction of Tilapia in the system, which eventually leads to overcrowding and stunted growth. Additionally, if newborn fry somehow get in the grow trays they will start eating the roots of the plants relentlessly and will not stop until the plants are dead.
Due to the natural genetic makeup of each individual pure breed, our breeder colonies made up of Hornorum males and Mossambica females will produce fry that are almost all male naturally; not treated with sex-reversal hormones as is the current industry accepted practice.
No females, no hanky-panky in your tanks, life is good.
Almost? I have never seen a female hybrid. According to my teacher, however, there is a 2% chance that a female hybrid can occur. These females, should they happen, stand a very slim to none chance of ever reaching breeding size.
The hybrid males, in the mean time, will grow faster and bigger than either of their parents and will inherit some of the male’s “improved body form”.
This combined with Tilapia’s natural resistance to disease and ability to thrive in much less than perfect water conditions makes them the ideal fish for aquaponic systems.
It is also a great business opportunity besides selling table-ready Tilapia!
By purchasing your own breeder colonies you can market all-male fingerlings to other aquaponic system enthusiasts!
Of course you can also bypass the whole breeding part and just purchase as many fingerlings as you need.
Pure Breed Blue Tilapia breeder colonies
Blue Tilapia is popular with backyard aquaculturists because it is relatively easy to obtain and not regulated as closely (or at all in many states) as other breeds.
In commercial aquaculture they are routinely hormone sex-reversed to achieve an all male population. Ours are pure-breed, all-natural, hormone-free and they work fine as long as you keep in mind that you will have mixed-sex offpring which themselves will continue to reproduce and overcrowd your tanks if not managed properly. as you can see, the top right one is a female about 4 inches in size carrying about 200 fry in her mouth already!
Nile Tilapia breeder colonies
Nile Tilapia have been used extensively in commercial aquaculture but unfortunately are routinely hormone sex-reversed to achieve an all-male population. Ours are genuine hormone-free, all-natural Nile Tilapia breeders and will produce mixed-sex fingerlings just as they should.
If you have ever had an aquarium and actually kept your fish alive for longer than a month, you are already half way there! If you have not had one, I would suggest purchasing a small 10 to 29 gallon one and buying some “feeder goldfish” to learn the basics. I started out with one goldfish and a one gallon aquarium (I’m a slow learner). Then just click on the “how you can do it” button on the left.
Whether you are a beginner or a pro, one thing you will find useful here is that I do not use industrial strength Aquaculture language, and what I suggest you do is what has worked for me after the customary “trial and error” routine. Which means: if you know better, let me know, I’m always looking for the “EBW”. (Easier Better Way)
Anyway, here’s the latest. I went to Whole Foods Supermarket. They have the closest thing to the offspring from my breeder colonies out there: no sex reversal hormones, no antibiotics or preservatives, and fed good quality food. They still have to import them from Costa Rica and Ecuador and go for $9.99 a pound for fillets! Growing your own does pay! Even the best commercial fillets can’t be as fresh as your own!
Now! If you are the type who says: “Geeez, if I want fish I’ll just go to the supermarket and get it”, think again. What would you do if for A, B, C, or “D” reason there isn’t any available anywhere at any price? or any other kind of meat for that matter?
