When you learn grow-out in Tilapia farming you have to deal with: density, aeration, and food.
Remember, these parameters are not absolute requirements. You can go at your own pace and achieve the same results in a longer period of time. I use degassing units with splash down and our simple injectors. This encourages faster grow-out with low density tanks.
Here is the formula: in order to raise a tilapia fingerling to 1 pound, you need to provide it with 1 pound of oxygen and 1 pound of food.
Here’s the trick, though. We need to provide these materials in just the right amounts over the desired length of “grow-out” time – generally anywhere from 7- 8 1/2 months. The first question that arises is density: How many can I place in the tank?
Farmers say a rule of thumb is to allow for a carrying capacity of 2 pounds of biomass (Tilapia) per cubic foot of water. Densities of 5 pounds per cubic foot or higher can be accomplished with more sophisticated equipment.
In order to grow 66 Tilapia to 2 pounds (908 grams), you will need to dissolve in the water 6.8 grams of oxygen per hour for 12 months.
If we were to increase the dissolved oxygen to 10.4 grams per hour and provide better waste disposal and water changes, we could do it in 240 days (8 1/2 months)!
We must ensure that you feed your fish well besides maintaining favorable environmental conditions during the grow-out phases. Remember that tilapia reach a harvestable size in a matter of six to eight months with Tilapia farming. This also depends on the species you have.
On September 5, 2013 at 7:00 pm Central (USA) we are hosting our live training webinar
This exclusive and comprehensive training is one of a kind. It includes more on the details we’ve gone over in this series, plus information on:
- Choosing the right location
- Setting up your brood, nursery and grow out tanks
- Selecting quality brood stock
- Fry Care
- Sexing tilapia
- * Our Secret Tilapia Food Recipe we have used for years that will accelerate your fry’s growth safely and organically! This process alone is worth the cost of the webinar as it will produce a superior brood stock and set your Tilapia’s growth speeds to reach maturity faster.
- We are also offering the webinar digitally for download, so you’ll be able to reference it at any time in the future.
This will all be for in introductory of $99, after this it goes to $199. Even at $199 it’s a steal. You can make this back from your first sale of brood stock!
I used to offer just my fry care training for $325 and tilapia breeding at $500 per person. With this webinar you get $825 worth of training for an introductory cost of $99. I don’t know how long our staff will offer this, but since you’ve come this far, you’ll definitely want to get in on this training while you can. You’ll want to join us for our upcoming webinar because it is going to be packed with information to get you started right away.
