General
- Overview of integrated growing with duckweed and algae - [1]
Growth Rate
- Exponential, linear, and plateau growth rates are the normal course of life of a tilapia. Depending on the genetics, the growth rate is linear up to from 1-3 lbs of weight. Linear phase starts at 100 grams, and before that, the rate of weight gain increases. - [2]
- It takes 6-12 months until harvest. - [3]
- 2% average growth rate of tilapia - [4], but .7% if fed duckweed alone - [5].
- Fish growth in lenght is linear, but weight gain is overall exponential in the general case - [6]
Stocking Rate
- 1/4 lb per gallon without supplemental pure oxygen. With oxygen, stocking up to 1 lb per gallon is possible. -[7]
- 5-9 lbs per cubic foot with oxygen - [8]. Same? 1 cubic foot = 7.5 gallons. Thi
- Bright Agrotech - correct stocking rate of 1 lb for 8-10 gallons of water - [9]. This rate allows for flow aearation, as opposed to air pump aeration - allowing the splash of flowing water to provide adequate oxygen. Summary: this figure is 1/2 or less the MSU publication above - so consistently conservative.
- 3 gallons to one pound of fish - [10]
Stocking Rate for Fry
- Southeast Asia stocking of fry - not adult carrying capacity of the water - .7 kg/m2 - [11] - if 1 meter deep, that is 264 gallons
