The document provides guidelines for maintaining healthy fish and plant production in an aquaponics system. It recommends monitoring water quality, providing good aeration and filtration, and using biological and non-chemical methods to control any diseases. Key factors include keeping fish actively swimming without lesions, balancing nutrients like nitrogen and phosphorus, and supplementing with calcium while controlling pH levels.

2. Have a good
production

3. Water quality is key
•Fish should be:
1.Actively swimming
2.No lesions or red
spots
3.Eating regularly

4. What if my fish
get sick?
1.Most diseases are a result of
poor water quality
2.Check water quality
3.Do water change if necessary
4.DO NOT ADD SALT!
5.Quarantine fish if disease is not
water quality related

5. Water, but not too much
Oxygen but moist
Nutrients balanced:
- nitrogen
- phosphorus
- calcium

6. What if my plants
get sick?
A)Soil borne diseases will not
be a problem
B)Non-chemical methods:
1.Biological control
•Resistant cultivars
•predators
•antagonistic organisms
•barriers, traps
2.Manipulation of the environment

7. Guidelines
are:
1.Use a feeding rate ratio for
design calculation.
2.Keep feed input relatively constant.
3.Supplement with Ca,K and Fe.
4.Ensure good aeration
5.Remove solids.

8. Continued…. 6.Be careful with aggregates.
7.Oversize pipes.
8.Use biological control
9.Ensure adequate
biofiltration.
10.Control pH.

9. Conclusion
