Catfish Farming - Coggle Diagram

- - - - High Protein
        Above 30%
      - Fat
        Above or equals 5%
      - Abu
        Max 13%
      - Serat Kasar (crude fibre)
        Max 8%
    - - Zooplankton
        
        eats Phytoplankton
        
        main needs
        
        needs Nitrogen
        
        needs Phosphorus
        
        needs Sunlight
        
        if too much
        
        the root cause of
        Algae Bloom
    - - Cortisol
        Measurement of Stress
        
        A response of a stress,
        Produces fight or flight instinct
        
        High cortisol = high stress
        
        It will divert all energy to "essential functions" only,
        suppressing Metabolism and Reproduction functions
        Even in biology, resources are finite :)
      - Methods
        To reduce Fish Stress
- - - - Gill Damage
        Makes Hard to Breathe
      - Higher stress.
    - - Decomposition of Organic Matters
        (Food, Dead Fish, etc)
    - - Flow through system
        A.k.a Kocor
      - Minimize organic waste
        (Uneaten feed, dead fish, etc)
      - Aerobic Decomposition (Nitrification)
        For faster decomposition
        
        achieved by Aeration
        Aerobic needs Oxygen
      - Reduce PH
        
        Higher PH leads to Ammonia
        
        Lower PH causes Ammonia turns into Ammonium (less toxic)
