What are the disadvantages of aquaponics?
What are the Disadvantages of Aquaponics?
- Aquaponics is Not Suitable for All Crops.
- Cost of Electricity.
- Set Up Costs.
- Expensive to Upscale.
- Needs Technical Knowledge.
- Not A Lot of Fish.
- One Part Fails, It All Fails.
- Overall.
Do tilapia like cold or warm water?
The tilapia should ideally be kept in water with a temperature of 28-30 degrees C (82-86 degrees F), this might however not be practical in colder areas. Luckily it is possible to farm tilapia in colder water even if this will affect the growth rate.
What temperature kills tilapia?
